FBB Packet-radio BBS mini-HOWTO Miroslav "Misko" Skoric, YT7MPB, m.skoric@eunet.yu v1.18, 2003-06-01 This mini-HOWTO covers the installation and use of the most popular amateur packet-radio BBS server software "FBB". That software works under Linux, DOS and Windows operating systems. It serves as a bul­ letin board system (BBS), a mailbox for personal messages, a database for various texts, documents and binary files, a server for small use­ ful calculations etc. Packet radio is a way of connecting computers via amateur radio stations. 1. Introduction I have been using FBB amateur radio software since early nineties. It was the time of DOS operating system, so most of us, system administrators (or, so called system operators - sysop's), used various packet radio server software for DOS. Versions of FBB packet radio BBS server software for DOS, today are known as "DosFBB". I still administer one DosFBB database in the SRV (Amateur Radio Union of Vojvodina, a part of SRJ). It is DosFBB v7.00g23 that runs on a 486DX computer with 16 MB of RAM and Hercules b/w graphics. Since December 1999, it runs without any re-boot (excepting some power failures). Before that, it was a bit tricky to set up all memory management properly, in order to avoid "frozen" system. Although this server runs under DOS, its "radio clients" don't depend on that. In fact, users of that DosFBB might run their client software under DOS, Windows, Linux or any other operating system that offer amateur packet radio abilities. I have also used DosFBB v5.15c on a 286/12 box at home. Five years ago, when I got better box, Pentium I at 166 MHz with 32 MB of RAM and VGA color graphics, I switched to a Windows version of FBB ("WinFBB"). Author of the software, a radio amateur from France, Jean-Paul F6FBB, has made many versions of WinFBB, including 16 bit variant for Windows 3.x and Windows 9x as well as 32 bit variant for Windows NT. I have run both variants until now (at the moment it is 16 bit WinFBB v7.00g25 that runs great under Windows NT 4.0). New: Since Spring 2001, I run WinFBB v7.00i (17 March 2001) under Windows 2000 Professional. The main difference between DosFBB and WinFBB is that the second one offers you to do other jobs with your computer, while FBB is running as just any other application. Beside that, it is always nice to copy a text from another application (for example, from an Internet email) and to paste it into a packet radio message, or vice versa. In the mean time, I upgraded my system to the Celeron 400 MHz with 96 MB of RAM and a big hard disk that has enough room to install Linux and try LinFBB ... New: In July 2001, I added more 128 MB of RAM so my home system is very confortable now. Finally, you should be aware what I want to have here: 1. WinFBB when I run Windows. 2. LinFBB when I run Linux. It should be an Xwindow application that may be started/stopped similarly to WinFBB. That's why X11 LinFBB package is used. 3. LinFBB when I run Linux, but as a daemon that runs in the background. In addition, an interface for a local user (myself) is needed, as well as an interface to monitor the radio channel. 4. All three versions must be capable to share the same configuration files, i.e. to be able, for example, to begin a new session from the exact position where the other version has finished its own last session. 5. I am not an expert in Linux, so I am only able to install "factory-made" packages for Linux (just like to install self executing software packages under Windows). I mean of RPM packages. So, there are no source (re)compilations here at the moment, but in the future we will see :-) 2. How to install X11 (Xwindow) version of LinFBB · First of all, you should have running Linux with a GUI installed. I am fully satisfied with Gnome GUI but I suppose that KDE will be OK too (or any other GUI available). · Download or copy LinFBB (the main ftp site is ftp.f6fbb.org but there are many mirror sites too). For example, if you get a file like x700e_full.tgz it means that it is X11 version 7.00e and it contains all you need in tgz archive to install the BBS. On the other hand, a name like xd700g_full.tgz means that it is not X11 but daemon version 7.00g and it is also com­ plete to unpack. Further, x700f01.tgz and x700g.tgz are "upgrades" to any previous "full" package. For example, after I have upgraded to x700g.tgz I started to run X11 LinFBB 7.00g (04 August 1998). Btw, X11 versions are not maintained anymore, but I still run it here. It has some bugs but I like it. · Copy the archive file in /tmp directory. · You have to make a "base" directory where your FBB will be installed. For example you may type: mkdir /usr/local/fbb if you want FBB to be there. You have to be logged as · Then, you should locate yourself in that directory: cd /usr/local/fbb. · Now, you should unpack the archive: tar xvzf /tmp/x700b25.tgz (<-- use the right name of the archive here). · When you finished unpacking the archive, you may continue installing the software: ./install.sh is the command for that. The setup will ask you for the 'base' directory where FBB will be installed. If you chose /usr/local/fbb again, you will be told that such directory already exists and all files will be overwritten. It is OK, so you should answer yes. If everything is fine, you should see on the screen that fbb system directories are created. At the beginning of that procedure, program will ask you for BBS's callsign, name of the city, QTH locator, your name etc. That details will become a part of /usr/local/fbb/init.srv file. · After that, you MUST check this file again manually in order to fix some other details needed (because installation script does not fix all parts within that file). · Well, so far - so good. After you have checked all configuration files, you may start the software: ./xfbb.sh (<-- type this within an xterm or something similar). When you start your BBS for the first time, it will ask you to create some files it needs, so you should answer "yes" to the questions. 3. How to install LinFBB in addition to existing WinFBB Notice: Folks, you see, at my place, I have a dual-boot system, consisting of Windows NT and Linux (each of them having their own partition(s) and file system). I wanted to have 'independent' operating systems that won't see each other. So I made two NT's partitions as NTFS partitions and rest of the space used Linux as ext2 & swap partitions. Well, at first I have installed WinFBB under NT and X11 LinFBB under Linux. Both of them worked, but there was a big "problem": I could not share their system files. You might say: So, what a big deal. But, my FBB's should serve as packet-radio forwarding stations (regardless of which one I boot at the moment), so it was really needed for new LinFBB to "know", for example, the position where WinFBB has stopped the mail exchange last time (and vice- versa, of course). · Well, in order to allow both WinFBB under Windows NT and LinFBB under Linux to use the same system files, it is needed to put these files in a place that both operating systems are able to "see". So I do that by re-installing WinFBB onto a FAT (FAT16) partition that is recognized by NT and Linux too. The best way to do that is to install a "fresh" copy of WinFBB on a FAT partition and to copy complete "old" WinFBB from NTFS partition over the fresh installation (whenever you are asked to rewrite existing files, you should answer "yes"). · When that is finished, you should have a "clone" of the existing old WinFBB, but this time on the FAT partition that is visible from under Linux. Anyway, you should check if the "new" one installation is able to run properly as the "old" one. · I could also recommend you to check the file tree of WinFBB in order to become more familiar with it. The file tree of LinFBB is a bit different so it is advisable to note various details here and there. · Some files can't be used as they are under both operating systems (without some necessary changes). That's why some file names should be renamed (or, at least, you should make appropriate copies of some files): init.srv -> init_w.srv forward.sys -> forw_w.sys port.sys -> port_w.sys protect.sys -> prot_w.sys FBB is able to recognize and accept those renamed files. · Make a backup of the actual WinFBB (I do that by copying the whole WinFBB file structure into the other Windows partition that won't be shared with Linux, like NTFS one). You'll never know when a catastrophe may happen, so as a result, you won't be able to start neither of the "old" WinFBB or the "new" LinFBB. As a precaution, the backup might be the easiest way to recover at least the old WinFBB for a while (until you configure your new LinFBB, ok?). · Now, you should restart your machine and boot into Linux. Log on as 'root' or make 'su' from a user's account. · Mount a shared FAT directory (where FBB files are): mount -t vfat /dev/hda2 /mnt/win (for example). If that works, later you may adopt that change within your /etc/fstab configuration. · Copy LinFBB archive to /tmp directory. · Position yourself to the 'base' directory: cd /usr/local/fbb (for example). · Unpack the archive: tar xvzf /tmp/filename. · Start the installation script ./install.sh and, after asked for the 'base' installation directory, chose /usr/local/fbb. It doesn't matter if the program warns you that such directory already exists so existing files will be overwritten (by the way, if you choose a mounted directory shared with NT, many original WinFBB files, located there, would be over-written by LinFBB files, so after returning to Windows, WinFBB might not be as functional as before this installation). · Copy /usr/local/fbb to /mnt/win/fbb but do *not* rewrite existing files with the new files having the same names. · Copy /mnt/win/fbb/init_w.srv to /mnt/win/fbb/init_l.srv file. · Edit /mnt/win/fbb/init_l.srv to what is needed for Linux. You may use the existing file /mnt/win/fbb/init.srv as an example. · Copy newly edited /mnt/win/fbb/init_l.srv over the /mnt/win/fbb/init.srv (if you do not do that, maybe you wouldn't be able to start LinFBB using ./xfbb.sh, like me at the first time). · Copy /mnt/win/fbb/system/port_w.sys to /mnt/win/fbb/system/port_l.sys file. · Edit /mnt/win/fbb/system/port_l.sys to what is needed for Linux and LinFBB. You may use the existing file /mnt/win/fbb/system/port.sys as an example. · Edit /mnt/win/fbb/xfbb.sh in order to fix the right path. · Ensure that you are in FBB's main directory: cd /mnt/win/fbb (for example). · Start the script ./xfbb.sh to run LinFBB. If everything is OK, your LinFBB under Linux should run with the same configuration as your "old" WinFBB under Windows. From this point, both FBB's should behave very similar (actually, I must admit that WinFBB has much better visual quality than X11 LinFBB, but probably the reasons for that you may find in Windows-vs.-Linux-GUI quality "battle field"). FYI, my actual WinFBB is v7.00g25 (05 January 2000) and X11 LinFBB is v7.00g (04 August 1998). · Although this combination WinFBB/X11 LinFBB works fine, I have noticed some problems. For example, LinFBB was not able to use amsat forward_to_file routine (located in /mnt/win/fbb/system/fwd directory), because that file was composed like this (for example): A AMSAT * P @ * C D:\FBB\SYSTEM\SAT\AMSAT.TXT <-- looks familiar to DOS/Windows only * G AMSAT * -------- On the other side, LinFBB's amsat.sys (located in /etc/ax25/fbb/fwd directory) has suggested something like this: A AMSAT * P @ * C /var/ax25/fbb/sat/amsat.txt <-- looks familiar to Linux only * G AMSAT * -------- Well, then I copied LinFBB's amsat.sys into /mnt/win/fbb/system/fwd directory so it could become functional. As a result, I got two amsat.txt files, one of them for each of WinFBB/LinFBB, and of course, both files appeared on different locations: the first one was /mnt/win/fbb/system/sat/amsat.txt and it was filled by WinFBB; the other one was in /var/ax25/fbb/sat/amsat.txt and was filled by LinFBB. I didn't like it that way. In order to have only one result, regardless of FBB version, the newly copied amsat.sys had to be slightly changed: A AMSAT * P @ * *C /var/ax25/fbb/sat/amsat.txt C /mnt/win/fbb/system/sat/amsat.txt * G AMSAT * -------- As you can see now, when LinFBB is active, its amsat.sys will not forward into its "native" location of amsat.txt. Instead of that, it will go to the location of the WinFBB's amsat.txt and just add some new materials into it, ok? Well now it's up to you to decide what to do with your growing amsat.txt. An old DosFBB manual says that the 'batch' file (I suppose, the old good APPEL.BAT) should be adopted in order for SATUPDAT.EXE can update sat tracking data and, after that, to erase AMSAT.TXT because it is not needed anymore. Well, I haven't found a way to manage that in both WinFBB and LinFBB. Actually, whenever I perform housekeeping from either of them, it seems that AMSAT.TXT remains intact. Happily, it doesn't grow too much, so it's not a big problem. Any suggestion here? 4. How to install Protus password utility Notice: Well, I have been using Protus connection filters for a long time now. At first, it was the version 3.1/1.2 for DosFBB515c and, later, version 3.3 for Dos/WinFBB700. I have found Protus as very useful utility because of its implementation of automated BBS-to-BBS forwarding protection, using MD2 algorithm. One of the reasons to cover Protus in this document is the fact that its author haven't made a manual in English yet. I keep trying to translate original manuals from Spanish into English, but it is a hard work. Any good 'spanish- to-english' translator is welcomed to contact me: m.skoric@eunet.yu. Protus offers several interesting features: · It can send a presentation message to all users, informing about possibility to make users' access more safe, · It can send messages to users who have usual, non-restricted access, informing about utility's existence, · It can send messages to users who have no valid access (before disconnecting them), · It can send messages to new users who have connected the BBS for the first time, informing them about the password utility. · It can send messages to users who have entered wrong password (before disconnecting them), · It can inform sysop about almost everything related to users' connections (new user on the system, unsuccessful connections etc), · Messages mentioned above could be translated into various languages and used similarly as various language files that FBB system use, · Messages mentioned above could be different for different BBS ports, · Protus could be activated/deactivated at various intervals of time using CRON.SYS system file, · Passwords could be managed remotely, using an external server, developed by Jose EB5IVB, · ... Well, let's see what should be done in order to implement secure access to the FBB packet radio BBS, using Protus type of, so called, c_filter: · Users of Dos/WinFBB versions of Protus already know that it is needed to create a new directory \FBB\PROTUS where several *.PRT files should be placed. In addition, the main C_FILT*.DLL files should be copied into \FBB\BIN directory, as well as a couple of "system", (i.e. config) *.PRT files that are going to be within \FBB\SYSTEM directory. · After the sysop has copied all files into their proper locations, it is needed to make some configuration. The most important files are two "system" ones: CONFIG.PRT and USERS.PRT that should be carefully adopted to any particular situation. Other *.PRT files will work as they are in original, but they may be translated because they are originated in Spanish (those files are just the parts of information that are sent to users who connect to the BBS). For your information, I usualy don't care much about, because my BBS's are so called "open systems". It means they work quite normal for all users in the same way as they worked before implementing Protus. Only a couple of callsigns have password installed and, when connecting, they know what they are doing, so, they don't need any additional info. Your mileage may vary. · So far - so good. After everything mentioned has been done, you have to restart your FBB in order for Protus utility to be activated. In all connections to your BBS (including console), you should see a line like this: {PROTUS-4.0} just after the well known line [FBB-7.00-AB1FHMRX$]. It only gives an information that Protus is active on the system. Users of your BBS who don't have their passwords, connect just normally as before. Users who's callsigns have password implemented, are prompted for password just after their connections. roman } · The author of Protus, Jesus EB5AGF, has made several working "modes" of its utility. It is possible for users to have various kinds of passwords: a fixed phrase (similar as those you are used to when connect to the Internet via telephone line, but this way the phrase can be masqueraded within the longer answer); a changeable answer to the 5 random numbers (just like usual FBB sysop's password); a mode that uses automatic answer from user's client packet programs; implementation of MD2 and MD5 algorithms; FBB-to-FBB automatic protection etc. FYI, my WinFBB is equipped with 16-bit Protus 4.0 (13 August 1999). There is also a 32-bit module of the same date that would be called from within 32-bit WinFBB (I haven't tested those 32-bit applications). · Well, the situation regarding working location of Protus files under LinFBB is somewhat different. I have become familiar to the directory structure that DosFBB and WinFBB versions of Protus have been using, so I considered that it was enough to implement the same directory structure when I started the installation of Protus under LinFBB. It was wrong. After having pulled out the remaining hair, the things started to work, so, now I am going to tell you what to do. · I have already told you that I have been running here both WinFBB under Windows NT and LinFBB under Linux (see also Linux+WinNT mini- HOWTO and Lilo mini-HOWTO). That means all Protus stuff has already been installed in a way WinFBB has required, except Linux executable of c_filter file. I put that one file into /fbb/bin directory and, after the next restart of LinFBB, I got the info mentioned above: {PROTUS-4.0}. But the password protection was not likely to work. I was told by the author to make a new directory /var/ax25/fbb/protus and put *.PRT files there. I didn't move files from \FBB\PROTUS but rather copied them into the new location, because I wanted Protus to continue working under WinFBB as before. The utility still didn't want to run, unless I also copied additional two *.PRT files from \FBB\SYSTEM to the same new location (/var/ax25/fbb/protus). After I did that, Protus became functional. · Well, I suppose, the above info would be useful for those of you who intend to run *both* Windows and Linux FBB's on the same machine. For the majority of LinFBB-only users, it is just important to make /var/ax25/fbb/protus where all *.prt files should be placed. Only c_filter executable should go to /fbb/bin and that's it. · About FBB-to-FBB protection: *both* partners have to install Protus. Password for the forwarding partner's callsign must be the same at *both* sides of the link. The versions of Protus don't need to be the same (neither the versions of FBB, neither the operating systems, HI!). Anyway, MD5 algorithm will only work if both parties have Protus 4.x and above (I still don't use that, but it is not a problem, because my two boxes, DosFBB-Protus3.3 and WinFBB/LinFBB- Protus4.0, make all things OK with MD2). · One of the interesting features of Protus is to log unsuccessful connections. Due to the different locations of *.prt files here, I have separate logs for WinFBB and LinFBB "c_filtering". Those of you who are going to run only one operating system and appropriate version of FBB, will have one complete log of connection errors, users make when try to connect your BBS. · As it was told earlier, if you implemented password protection for only some of your users (but not for all of them who connect normally) - your system is considered as the "open" one. It means that will be logged only unsuccessful tries to enter the system by "protected" callsigns. But, if you decided that your BBS can be accessed by only those callsigns who have Protus password, that means your system is the "closed" one. Then, there is no way a user could enter your FBB unless its callsign has given a password within your Protus. Any unauthorized try to connect your BBS is also logged. · In addition, you may decide to have a "guest" access or a "read- only" as default for some BBS's access ports and/or for users who enter the wrong password. Many combinations are possible. You could even password protect your own FBB console! · To finish with this topic for now, just to inform you that my X11 LinFBB is equipped with Protus v4.1b7 (15 February 2000). It has some minor bugs, for example, it logs incoming connections with a SSID of -48 if a user doesn't have a SSID at all (of course, in such case a SSID of -0 would be expected). } 5. How to install "xfbbd", a daemon version of LinFBB Notice: You see, folks, that I keep trying to get as many as possible versions of this great software (Jean-Paul, F6FBB, must be very proud after reading these words now). What I think when mention "as many as possible versions" means that we have learned how to get both WinFBB and X11 LinFBB on the same computer. But, that's not all. There is a variety of daemon versions of LinFBB. In this section we are going to discuss how to *add* a daemon LinFBB to the existing two: X11 LinFBB and WinFBB! · Well, many amateurs have suggested me to install a couple of packages that weren't look to me as really requested for LinFBB daemon to work. Anyway, I installed those packages before the installation of LinFBB itself: libax25.rpm ax25apps.rpm ax25tool.rpm · Now it is the right time to install fbbsrv.rpm package. The archive was composed to make its own directories, as "base" directories. The last new version to start with, that I have managed to find as a .rpm package, was 7.01f Release 4 (09 December 1999). · A file called fbb.conf, serving as the replacement for init.srv, is placed in the location: /etc/ax25/fbb.conf · Unless you are going to install daemon-only system, you should make a backup of the following existing files: dirmes.sys etat.sys heard.bin inf.sys statis.dat tpstat.sys · Now you have to edit /etc/ax25/fbb.conf and change some paths in case you already have X11 LinFBB installed on a different path. Here you have some examples that cover my particular situation... · Directory of data files, instead of /var/ax25/fbb, should be /mnt/win/fbb/system · Directory of config files, instead of /etc/ax25/fbb, should be /mnt/win/fbb/system · Directory of message files, instead of /var/ax25/fbb/mail, should be /mnt/win/fbb/mail · Directory of compressed files, instead of /var/ax25/fbb/binmail, should be /mnt/win/fbb/binmail · Directory of users, instead of .../home/fbbdos/..., should be .../mnt/win/fbb/users... (case you don't mind that both your WinFBB and LinFBB users handle the same location for users' files) · Directory of YAPP files, instead of /home/fbbdos/yapp, should be /mnt/win/fbb/users/yapp (the same reason as above) · Directory of documentation files, instead of /var/ax25/fbb/docs, should be /mnt/win/fbb/docs · Directory of pg programs, instead of /usr/local/pg, should be /mnt/win/fbb/pg · Path and filename for import file, instead of C:\FBB\MAIL.IN should be /mnt/win/fbb/mail.in · Now you have to edit /usr/sbin/xfbb.sh and change some paths in case you already have running X11 version of LinFBB on a different path. Here you have an example that cover my particular situation... · Base directory of XFBB software, instead of /var/ax25/fbb, should be /mnt/win/fbb · So far - so good. Now it is the time to start LinFBB daemon. The command for that is in the location: /usr/sbin/xfbb.sh and it may be executed within an xterm. If everything is OK, you should get several system messages on your screen, ending with something like: xfbbC/X server running ... xfbbd ready and running ... · Well, daemon itself can't be used to access the BBS so it is needed to activate a client that is /usr/sbin/xfbbC. It has a couple of parameters (a callsign/password pairs that are stored in /fbb/passwd.sys). Note that xfbbC can also be activated within another xterm. · If you are like me, you would like to activate one more xterm with xfbbC in a way to monitor your radio frequency. If you have enough room on your screen, you may place all three xterm windows side by side. · When you finish your xfbbC console session, it is suitable to use the same xterm to eventually stop the daemon. First of all, with the command ps ax you should locate PIDs of xfbb.sh shell and daemon itself, that you may kill after that. 6. How to install an upgrade to a daemon version of LinFBB 6.1. LinFBB v7.02g Notice: Well, the main trouble I have discovered with 7.01f daemon was the absence of Protus c_filter protection. As I told you before, Protus is a "third-party" product, so it might have some problems with the compatibility to LinFBB itself. Anyway, it is also possible that a daemon version of LinFBB has some special requirements over some "third-party" software. · I also noticed that my version of Protus was newer than the version of daemon LinFBB I had at first. Besides that, some hams, including F6FBB himself, have suggested me to upgrade LinFBB. I have also found a "problem" that I am still new in compiling Linux software, so, I'd rather look for pre-compiled packages for easy installation. · Jose, HI8GN, has offered daemon LinFBB v7.02g as a .rpm package (18 September 2000). I got it from his site: http://hi8gn.dynip.com/indice.html . But, when I tried to install it over the previous version 7.01f, it complained about some existing LinFBB files. · Then I had to uninstall the old package, after what some config files remained in their locations, but with new .rpmsave extensions. It was nice, so I could use them later to update my new-installed config files. · Btw, the installation of Jose's package was performed without problems, but the new daemon was not likely to run as I expected, although I tried to configure it as best as I could. Not quite sure, but it looked to me that F6FBB is likely to implement some changes not only to the main executables but to shell files too. So, I have decided to save copies of these new xfbbd and xfbbC executables from 7.02g package (I have made it with adding extensions like .702 to the files). After that, I *uninstalled* the rest of that 7.02 .rpm, in order to install the previous version of LinFBB once again - the version that I was satisfied with. · So far - so good. The "old" 7.01f version was installed again and tested one more time to be sure it was OK. Then, I just copied the previously saved executables from the new package, over the "old" executables. In a couple of minutes, the new daemon LinFBB v7.02g has come in place and function. Comments...? · Well, the new daemon is likely to check for some more directories than the older version (mostly related to 7plus operations). Next, its xfbbC console client looks better than the previous version. But, I still miss graphical xfbbX client, that I have found not able to become activated. I hope it will be fixed soon. Finally, Protus c_filter utility is active too. · An interesting question might be: is that now a really upgraded LinFBB daemon or not? Actually, I haven't changed the "old" script xfbbd.sh with the new one, because during the first tests with the new 7.02 I was getting lots of error messages. Looks that the directory structure was a bit complicated for me to set properly within the new version of xfbbd.sh. After I returned to xfbbd.sh from 7.01 package, the BBS finally started to be run, though without some functions like over-night maintaining (that one problem I solve in a way to boot the BBS as WinFBB under Windows NT where that task is OK). In addition, there are still some mysterious messages telling that m_filter has not been found or something like that. The next tasks are to solve these issues. 6.2. LinFBB v7.03 Notice: As I have said in the previous section, I haven't found an easy way to upgrade FBB's (its main executables), without temporary uninstalling an older version, then to install the new version - in order to get new executables. After that is done, a reverse procedure must be put in place. · Well, it was needed to get 7.03 package (09 December 2000) as an .rpm package from www.f6fbb.org/versions.html , that was suggested by Jean- Paul, F6FBB. Anyway, soon after there appeared several mirror sites, offering 7.03 too. · If you use GnomeRPM, it is easy to uninstall your actual LinFBB (If you just try to install new .rpm over the existing LinFBB you will get some error messages complaining that you already have FBB installed on the computer). Anyway, after the uninstallation, there you will find some config files as .rpmsave files, so you could use them later again. · Installation of 7.03 package will give you new executables in /usr/sbin directory. Those new executables should be temporary given extensions like .703 (for example). · So far - so good. Now you should *uninstall* the 7.03 package (of course, .703 files won't be unistalled automatically). Uninstall? Why? You will find out soon, read on ... · Once again, you should *install* the last one version of LinFBB daemon, that works OK with its own xfbb.sh (in my case, that is 7.01f). · For sure, many of you might find it odd, but now it is the right time for the executables from /usr/sbin (I mean of all fbb executables, except those who were renamed to .703) to get their new extensions (in my case, that is .701). · Well, after that is performed, .703 files should *lose* their previously attached extensions, in order to become usable. · Folks, on that point I usually hold my breath, cd to /usr/sbin and type: xfbb.sh following with an Enter. If everything is fine, several lines should scroll on the screen, ending with something like: xfbbC/X server running ... xfbbd ready and running ... · If you don't get something similar on your xterm utility), you're out of luck, so you might go thru the procedure once again in order to be sure you did all what was needed to be done :-> · /usr/sbin/xfbbC is the easiest way to check if your new 7.03 is in the game or not. When I mention xfbbC it is good to let you know, that I kept living in a belief that xfbbC is also useful for regular telnet users (who are also supposed to 'connect' to the BBS via the same computer's console, where LinFBB is running from). But, I have discovered that my users, who were not declared as sysops, are allowed to read all messages (including all private messages), as well as to have some other sysop's abilities. I did think it was a matter of probably wrong declared security flags. But, it was not. · Recently, I was informed that xfbbC is suitable mostly for sysops, so the other users (who might also have access to the local keyboard) should rather try something less dangerous, like this: telnet localhost 6300 · ... where 'localhost' and '6300' may vary from BBS to BBS. I was pleasantly surprised when discovered that telnet is much more suitable for ordinary BBS users than sysops' client xfbbC. · Folks, I also think of writing a chapter about FBB's system configuration. Until something like that appears in this howto, you should know that all of those callsigns who are going to use xfbbC have to be added into your passwd.sys file. In addition, all of these folks who are going to telnet the BBS, have to be declared as users with the 'M' flag (modem users). It is up to your security precautions, if either of them would eventually have 'root' capabilities to that one Linux machine itself. · My next task is to use an old i286/12 MHz box, having only 1 MB of RAM, running DOS 5.0, as a card so I would like to 'connect' to the BBS from that one 'telnet client' box. If that succeeds, it would be a good preparation for installing another LinFBB (in the local school club), where several old 286 computers will also be available. It would be nice to offer more than one student-amateur the opportunity to 'connect' the BBS simultaneously, using a bunch of vintage 6.3. LinFBB v7.04 Notice: Maybe I have already explained that I use Red Hat 6.2 at home. That's why I usually look for .rpm packages that have been made for that particular Linux distribution, but not only that. I have also tried to use Red Hat 7.1 but it seemed not to support an older Xwindow application, LinFBB 7.00g (04 August 1998). When I noticed that issue, I returned back to Red Hat 6.2. · Well, I started by downloading the package xfbb-7.04-2.i386.rpm (07 August 2001) from www.f6fbb.org/versions.html · Folks, this time I finally decided to install version 7.04 as a completely "fresh" installation, i.e. without some parts of any previously used "daemon" on the disk. It means that I have uninstalled the last daemon version I was using before, and, in addition, I also removed the old executables. Of course, before the uninstalation, I made the backup of some config files that are not version depending (like /etc/fbb.conf), in order to avoid editing the same "defaults" once again and again :-) · The setup procedure has reported some dependency issues. I didn't want to get bored with them so I repeated the installation once again with "--force" and "--nodeps" options. · So far - so good. Then, I replaced a couple of "default" files with the saved ones. After that being accomplished, I mounted a FAT partition with WinFBB's system files, made a pray and started LinFBB's daemon. It was also an interesting new experience to try HI8GN's script /usr/sbin/fbb start (activated in an xterm) to start the server. Although there were no usual lines: xfbbC/X server running ... xfbbd ready and running ... on my screen, TNC's PTT lamp confirmed that a beacon was really transmitted. · Then I wanted to try HI8GN's script /usr/sbin/monitor to see what's going on the frequency. Although I got something like: Connecting localhost ... Ok Authentication in progress ... Ok Monitoring channel 0 ... there appeared no traffic on the screen. In order to really monitor the channel, I had to start another xterm and type: telnet localhost 6300 Bingo! From the usual FBB's prompt I entered the gateway and typed the familiar "M" ("Monitor") command. Interestingly, as soon as I "telnet-ed" to the BBS, /usr/sbin/monitor window, mentioned above, started to copy whatever was going on the telnet xterm as long as that telnet session was closed. I was in doubt if that was OK or not, because there I expected to see the traffic from the radio channel - regardless being connected to the system or not. Any suggestion here? · Well, then I wanted to use /usr/sbin/bbs, in order to connect to the client's (or better to say: sysop's) console (xfbbC). Looks that there was a line in HI8GN's script: xfbbC -c -f -h localhost -i [callsign] -w [password] with missing ./ (dot slash) before xfbbC, so the script was not likely to be executed. Instead of that it reported that command couldn't be found. Anyway, xfbbC v3.01 itself appeared to work nice. It is still possible to monitor the working channel too (using the "M" command from within the gateway), but this is not a valuable solution because while "Monitor ON", it is not confortable to do anything else within the gateway. Once again, solutions are welcomed! · Although the active xfbbC session can be easily terminated using "B" ("Bye") command, a fooled /usr/sbin/monitor can not. The user has to find its process number, (PID), using ps ax command and then kill that process. · At the end of the game, daemon itself should be stopped. HI8GN's script /usr/sbin/fbb stop returns: Shutting down xfbbd: [OK] but /usr/sbin/fbb status reports: Checking, the FBB daemon xfbbd (pid) is running... Looks that /usr/sbin/fbb stop does not terminate daemon *every* time the command is executed, but re-start it (the only difference is the new PID of the process and ps ax can show that new PID). So, there is a question why it returns that [OK] when it is obvious that daemon is not stopped, but rather re-started. · Well, if you are like me, you may also want to experiment with some special sysop's commands, from within an xfbbC session. For example, "/R" command ("Re-boot PC") shuts down xfbbC and /usr/sbin/fbb status reports: Checking, the FBB daemon xfbbd dead but subsys locked while "/A" command ("Stop BBS") returns: Stop-request accepted, no connection. before shutting down xfbbC client itself. Further attempts to re-start either xfbbC client or xfbbd server (using /usr/sbin/fbb start) are not successful, unless an additional /usr/sbin/fbb stop is executed. The result is: Shutting down xfbbd: [FAILED] Now another /usr/sbin/fbb status reports: Checking, the FBB daemon xfbbd is stopped so finally, daemon might be re-started again. Here it is also a mystery why it returns that [FAILED] when it is obvious that daemon is really stopped (maybe it is a "failure" when we try to stop the same thing twice). There are some other commands: "/K" (Re-boot BBS with housekeeping), "/M" (Re-boot BBS immediatelly) and "/L" (Re-boot BBS, waiting users to disconnect) - all of them with slight different behavior. Anyway, those three commands have something in common: they all re-start the daemon (with different PIDs, of course). · Finally, what I would like to have is to manage housekeeping and other maintaining tasks. Until now, that is not accomplished. I suppose that I should make some more fine customization in system paths. Any suggestion about is welcomed. 7. How to use LinFBB's "xfbbX", a GUI client for Linux 2002-10-20 Well, soon after the installation of LinFBB v7.04 .rpm package, I noticed a new "kid on the block", i.e. a new item within the Start menu (under Gnome environment). That was a "HamRadio" group, having several "Xfbb version 7.04" sub-items and one of them was "xfbbd X Client". It seemed that a mouse click on that "xfbbd X Client" icon was not likely to return any response, although xfbbd daemon has been successfully running before invoking the client. That's why I have been asking for help (related to that issue) from other LinFBB users, but it seemed there was no one capable to solve that problem. Anyway, it looks to me that there is a "dead" link from this "xfbbd X Client" icon to an existing executable. Trying to find a solution, the other day I was browsing the /usr/sbin directory. I have noticed something that I have already seen for several times. That was xfbbX file. Well, I am sure that I tried to use this executable earlier, but without much success. This time, I have entered the full path, like this: /usr/sbin/xfbbX and, finally, the GUI client appeared on the screen. So far - so good. Soon after, I realized that 'Monitoring' window was capable to monitor the actual traffic on the radio frequency, but not only that. Headers of all packets appear in green and the actual information is in blue, so it is easy to distinguish what is the header and what is the text info (comparing to my old X11 LinFBB application where everything came in black). What I could describe as a disadvantage of the 'Monitoring' window, is that the scroll bar does not give you much of the previous, already scrolled traffic. The 'All channels' screen was even better, so the system user correspondents' traffic appeared in green, the local user's traffic was in black and the port information was in yellow. Unfortunately, there's no easy way (if any) to change colors (and that's the standard feature in WinFBB) for both 'Monitoring' and 'All channels' windows. Maybe I haven't managed yet to find a switch for that, so any useful info about is appreciated. What I have also found a bit annoying, was that both windows mentioned above, appear not arranged side-by-side, a form that would be more suitable. Besides that, the third window, 'Console', has to be activated with another mouse click (instead of being activated automatically with the other two windows). Actually, the whole thing of xfbbX client seems to be primarily useful for sysops looking only for BBS's command line, in order to execute some server's commands etc. That's why I have found a bit strange why the console window must be activated separately (OK, I know that's the same with WinFBB's windows, but why not to add some additional feature?) Anyway, the 'Console' connection window has almost the same functionality as WinFBB's 'Console' window. Here I think of the commands given at the BBS's command prompt, because they are invoked from the usual language *.TXT files. But, the big disadvantage of today's version of xfbbX client, I've found here, is the absence of several useful icons, that I was very fond of within the WinFBB's user interface. For example, there are no icons for pending mail, users information, disconnect a user, edit a message text or a header etc. It looks to me that xfbbX developers are not likely to offer the full comfort that we have within WinFBB's GUI. It makes me wonder why? There are lots of commands that can not be easily activated without the proper icons. It drives me crazy whenever I have to re-boot to Windows to start WinFBB, in order to perform some simple tasks mentioned, using the mouse. Besides that, there is no way to activate that nice message editor screen, very useful in WinFBB (also existed in an old Xwindow LinFBB application v7.00g from 1998!) The same goes for replying a message, where a sender does not get the text of a message to be replied to, within the new message body. In short, I don't like absence of all those earlier implemented, but now abandoned features. Well, I can't imagine what Jean-Paul, F6FBB, and other developers would do in the future, but I am not satisfied with the idea to only keep further development of LinFBB server side, but, in the same time, to abandon the development of LinFBB's graphical client side. And not only that: It looks that MS Windows client for LinFBB server, xfbbW has been reported to be much more functional that described xfbbX, while, in the same time, WinFBB server development has been also stopped. A bit confusing situation, isn't it? Some amateurs think that it is just a result of "global" IT situation: Linux (as well as other Unix-type platforms) is better suited for servers, but Windows is better for clients. If so, it looks that LinFBB packet-radio system operators, "sysop's", seem to be forced to run at least two computers, in order to get the same functionality they always had with WinFBB. I'd rather suggest to Jean-Paul, F6FBB, and other developers to transfer all known WinFBB's GUI features to xfbbX GUI environment, in order to avoid using two computers. 2002-10-30 A couple of paragraphs ago, I said that "xfbbd X Client" icon didn't work under Gnome environment. It did make me wonder if it would work under KDE graphical user interface. So, this time I started KDE (and I did it as "root" so, in addition, I also got a mailbox icon on the desktop, named "fbb X11". When I located the mouse pointer over that icon, there appeared some more description: "F6FBB bbs Server for Packet Radio"). Well, when I tried to click on that icon, I got a KFM Warning message box explaining that program /root/.xfbbX could not be executed. Fortunately, a "right click" on the icon allowed to enter file's Properties. The Execute card gave me a possibility to change the path for a program to be used. So, I did some browsing and located the new path: /usr/sbin/xfbbX. After that, another click resulted in running the GUI client. Interestingly, there is some slight difference between xfbbX appearance under KDE and Gnome. Actually, each KDE's xfbbX window has "FBB" logo in the upper left corner (Gnome's windows haven't that). That may indicate that xfbbX client was produced primarily for KDE environment. Besides that, it seems that other features are almost the same, regardless being within KDE or Gnome environment. On the other side, the already mentioned "xfbbd X Client" item (within the Start menu, under yhe "HamRadio" group), still does not work. I suppose that there should also be some modifications, related to program executable paths, but I do not know how to manage that. Anyway, it does not matter because xfbbX is running here this or that way. 8. How to use LinFBB's "xfbbW", a GUI client for Windows 2002-11-17 Notice: Well, folks, I couldn't try to install and use LinFBB client for Windows, because I have not had a second computer for that purpose. The only way to check how this client works, was to borrow a laptop machine and give it a try. The first task was to link that Windows laptop to a Linux desktop. I had some difficulties with the network card on the desktop box, because it seemed not to be likely to start the appropriate eth0 interface. I'll give you some more details about the equipment here: Linux is Red Hat 6.2 and my ISA network card has UMC UM9008 chip. Long ago, I used some utilities that should "recognize" ISA cards (if I remember their names, that were isapnptools, pnpdump etc). What I do know, is that such tools should have add some new lines into the existing files, like /etc/conf.modules or, to create some new files, like /etc/isapnp*. Well, I have forgotten what exactly should be done, so I went to look for the right tools. The one that was looking suitable was /sbin/isapnp. Although I got its response on the screen, telling that the UM9008 chip was recognized, there was nothing added to the system files, nor new files seemed to be created. What I also tried to use, was the old good Linuxconf tool, that was already installed per default within RH 6.2 Linux. I found the right place to add the information related to NIC's IRQ and I/O address. There I seemed to make a little mistake, so I put the value of 220 (for the I/O address), instead of 0x220 that would better fit. The result was as one may expect: the interface eth0 continued to report that a ne module had not found a card at that one address. Then I checked the actual I/O address the card uses under Windows OS (was the same) and tried to fix the parameters (Thanks goes to a UK ham who advised me to have to let Linux know the proper IRQ and I/O addresses). Interestingly, Linuxconf added a couple of new lines into /etc/conf.modules too. In short, the next time during the system boot, the interface eth0 reported a green [OK], so I could establish the link. So far - so good. The next task was to download the client package from the FBB's main site. I did it from the "Newest version" web page and the number of the version was 1.12 (it seems that was not a pretty much new version, or maybe the content on that "newest" page has not been updated recently - another task for Jean-Paul?). Anyway, I installed it without any problem, configured its part related to the LinFBB server it was about to access, changed the console font to my favorite one (Tahoma) and started the utility. At the first sight, the client looked great, because Linux clients still prefer so small letters, that are hard to read (compared to characters on a Windows screen). Now I tried the most used commands like List, Read, Send Reply etc. All of them worked great. What I have found a bit strange, was that the message justification did not work in its message editor window. You see, I like my messages to be justified on both sides. I hope a solution for that problem will be found soon. Another issue with xfbbW client is that seems not to allow a multiple click onto more than one BBS callsign within pending forward list, comparing to WinFBB's behavior. You know, I am not very fond of opening the same pending forward window repeatedly again and again, in order to start (or to stop) more than one forwarding action. In general, I like xfbbW client. I hope to install some newer version(s) soon, and I hope some of its features will be upgraded and some new ones will be added in the future. What I would also like to have, is to activate the maintenance of the BBS (a "housekeeping" task) from that client's menu. Another thing I miss at the moment, is the absence of the xfbbW's help system. I mean of a real Windows help, because there's not much use of a Help menu, having only Copyright and About information :-)) 9. How to compile LinFBB's executable files 2003-01-01 Notice: Until recently, I preferred to download "factory-made" executables in RPM format (something like ZIP in MS Windows world). After getting a RPM package, a click on it activates the program that unpack and install its content. Well, it is great whenever your RPM has been "manufactured" for the very similar distribution of Linux you have. If not ... · Well, I have already had the package xfbb-7.04-2.i386.rpm (07 August 2001), that was running OK under RH 6.2 distro. And not only that. Its "packager", Jose HI8GN, has explained that this package was actually compiled and linked with utilities that came with RH 6.2 - so under that distribution should be no problems at all. · The other day, I finally decided to abandon that 4-5 year old version of X11 LinFBB application that I knew it would not run under something newer than RH 6.2 distro. In short, I decided to stay with daemon LinFBB's only, so it was the right time to upgrade the Linux system itself. Another handy installation that I had, was RH 7.1 and I used it. After finishing that task, I rushed to re- install the RPM package above, but it just didn't want to run. · I had no choice but to browse fbb web sites in order to find a RPM package that would fit RH 7.1 distribution. Unfortunately, it looked that there were no LinFBB precompiled RPMs for 7.1 version of RedHat. The only solution was to try with tarballs. So, what I have downloaded from www.f6fbb.org/versions.html , was xd704h-src.tgz archive. · So far - so good. Well, folks, I am not very good in "deepest" secrets of Linux, so I was not sure where might be the best location to unpack the archive. According a readme file, it should be "fbbsrc" directory, so I considered that /usr/src would be the best place to copy archive's fbbsrc.704h directory. · fbbsrc.704h directory has been made of 12 files and 7 subdirectories, one of which is src subdirectory. As I said, the readme suggests a user to "goto fbbsrc/src" directory, and I concluded that /usr/src/fbbsrc.704h/src was the right place. · The readme also suggests to "update the variables" at the beginning of Makefile files, but I did not do that because I was not sure what should be replaced there. I have just left the file(s) intact. · The next task was to run make command from the shell and it took half a minute to be finished. The result were few new xfbb executable files that I quickly moved to /usr/sbin directory. BTW, some people rather suggest to run make install, in order to avoid multiple copying of compiled executables, but I found that way as not functional. · Soon after, I tried to activate LinFBB's daemon and it seemed to work without visible difficulties (using a temporary home LAN with a laptop, I also started fbbW, a LinFBB Windows client. It recognized the daemon in a second and I've only noticed that there was no Protus password utility running). · According the readme, the next task should be to "compile the xfbbC client". That operation is to be performed from a place called "fbbsrc/client" but the only directory available under /usr/src/fbbsrc.704h/src was X11 subdir. · After clicking on its icon, I recognized the second one file with a name Makefile (they have mentioned "updating" of both Makefile files, so I hoped to reach the proper place once again, regardless of two unknown paths). Besides that, they have suggested to use "at least the version 2.1.37b of ax25-utils" and I found not to have something like that installed (case they mean of a suit of libax25, ax25apps and ax25tool - than it is OK). Anyway, one more time I activated make command from the shell and the result was in getting xfbbC executable. · As usual, xfbbC client is invoked from within an xterm (or similar) window and it seemed that it was also fully functional. So far - so good. · The next issue is to "compile the xfbbX client", but this time a user is requested to have a version of Motif installed. Well, what I knew was that I had no Motif in the box, but a couple of Lesstif RPM packages were somewhere around. Anyway, I installed them with --force and --nodeps options to avoid several dependency obstacles. In sum, Lestiff has come to its place on the disk. · This time, I did make some "updates" related to Makefile paths and tried to run make command from the shell (for the 3rd time now). Seems that I got no answer, because there appeared neither xfbbX nor xfbbX_cl new executable files. In order to "solve" that issue, I just applied the executables from the earlier version I have backup-ed on the system. · Finally, I managed to activate xfbbX client without problems, although I knew it was not an updated version (compared to the daemon itself). Regardless of that fact, a GUI client works properly. · As I just mentioned, I noticed that the first console connections were without familiar {PROTUS-4.1b7} designation. So, I had to check and double-check all the paths and system directories, described in the Protus section of this mini-HOWTO. At the first sight, it looked to me that everything was fine, but the utility was not likely to start. Finally, I copied its main executable into the yet another system location: /usr/lib/fbb/filter, re-started the system and Protus returned back to its function. · What I have to do in the future, is to check if the procedure described in this section was the right one, although most of the BBS's main features seem to be active - like they were with RH 6.2 distribution and mentioned LinFBB packages in RPM format. 10. How to make better ham radio rules? 2002-10-27 Notice: Folks, here I am going to discuss some rule'n'regulation issues that we, radio amateurs, every day face to. These problems make rather significant obstacles for this nice way of communication to be more developed and widely used. First of all, anybody who might be interested in running Linux amateur radio software, as a way of using radio amateur stations on the international HF waves, in a digital manner, has to learn manual analog Morse telegraphy and pass the similar manual Morse skill test. For a long time now, I have been trying to explain myself, why manual Morse telegraphy is still being kept as the requirement without an amateur is not allowed to use HF radio frequencies under 30 MHz, in order to contact other Linux and remaining digital radio amateurs world-wide. I still have no answer, except that all of those who have wasted lots of time learning Morse, now don't want to allow newcomers to use the same capabilities - without the same (useless) tests! You all know, there are so many Linux enthusiasts world-wide (including myself) who have been fighting against all types of monopols (like a company from Redmond, USA). The Morse obligatory test is the same: just another type of a monopoly! That's why I have been trying to persuade all relevant authorities to remove such outdated regulatory principles, that make more and more obstacles for not only Linux users, but for other kinds of computer users - when it comes to the modern ICT technologies. I hope, all of you, readers of this mini-HOWTO, can now understand what does it mean to endlessly use outdated rules and regulations. For example, I often contact people from the academic world, students and scientists, in order to motivate them to join amateur radio wireless activities. They mostly refuse to start with amateur (also called "ham") radio, as soon as they hear they have to pass the Morse test, as the legal requirement before they become allowed to connect to remote computing radio users world-wide, using the HF radio bands and devices. I am sure, the absence of those high educated people in the ham radio is one of the most negative consequences in ICT areas we face to. I have been thinking what to do, since early ninetees when I was the secretary of YU7 (Vojvodina province in Serbia) amateur radio union. It seemed to me that it was a very hard task to persuade the people who govern the amateur radio organizations, to remove such outdated rule. When I realized that the removing the mandatory manual Morse test is almost impossible to be expected in a short period of time, I decided to suggest the implementation of another regulatory principle: To adopt a new type of amateur radio licenses, a Ham Digital Licence (the HDL in short). The HDL licensees would be allowed to use ALL amateur radio frequencies, including ALL international HF bands under 30 MHz. But, they rather should be allowed to use ONLY digital types of amateur activities, including the use of computers with LinFBB packet radio software. The HDL holders might use some dedicated radio transmitters, without the capability for both voice microphone and Morse key connections, in order to avoid possible misuse of unwanted amateur activities (like voice SSB operations). All HDL candidates would have to learn various topics like computer hardware and software in general (operating systems and system software configuration, amateur radio software setup etc), connecting amateur radio stations to the computers (connecting radio modems to the transmitters etc), building simple antennas (like 1/2 wave wire dipole for 20m I used long ago), English language (or German etc) in the written exam etc. The Morse requirement would not be used anymore, as well as some other obsolete tests, like highly complicated radio circuits or skills needed for building home-brew radios from the scratch (instead of buying modern factory manufactured devices) etc. Of course, regulatory issues should also be tested (like band plans - in particular recognizing the sub-bands dedicated for digital ham radio), RFI issues and how to avoid them etc. I believe that amateur radio digital activities have their future only if we all do our best to improve the regulatory principles that govern this fine hobby. You should also know that, besides the telegraphy skill requirement for HF access, here in Serbia we have some further restrictions: we have all to be the members of the national amateur radio unions (SRV in YU7 province and SRS in Serbia in whole), as the legal requirement, before we become allowed to use any type of the amateur radio activities. Such a stupid rule does not exist elsewhere! Should you want helping us to adopt internationally known principles, that do NOT require to join any type of an amateur radio organizational system, i.e. an amateur radio society (that only wants to get our membership money), you are invited to lobby for that. Our outdated amateur society leadership has their email address: yu0srj@eunet.yu (I suppose they may have more than one email address, but you may try to use this one). You may also use an Internet search engine and scan for more info related to "Savez radio amatera Jugoslavije", "Savez radio amatera Srbije", etc). Your valuable help would be highly appreciated. Case you need more info regarding these legal issues, do not hesitate to contact me too. If you find yourself interested enough in making amateur radio rules and regulations better and updated (say to spread the idea of liberalize the ICT areas and make them free of any kind of monopols), I would suggest you to look for your national radio amateur society and/or national telecommunication regulatory agency (like FCC in the USA). Lobby to them in order to remove the obsolete manual Morse proficiency test. In addition, should you have some opportunities to attend to some ICT related science conferences or something like that, you are also invited to let me know of. Case we all do our best to remove obstacles mentioned above and allow the new people who may wish to enjoy the amateur radio digital and Linux-related operations to do so, the technology would become the part of more homes. I hope you, the readers, may help. So I look forward to hear from you soon! 11. Bibliography 2003-06-01 Notice: Folks, I often visit some (inter)national ICT conferences all around Serbia and Montenegro, submitting papers and having presentations. What I want to do is to spread - as wide as possible - the basic idea and the useful mission of the amateur radio hobby. You bet, whenever possible I want my readers to make it with Linux. Besides that, I have been writing various articles for a variety of scientific and other magazines. Here you have a list of the articles I have written, and the papers submitted to the conferences until now.

I hope to improve it whenever possible. Beside that, there are other documents that may help you to use amateur radio stuff on your computer. You may also look for AX.25 (mini-)HOWTO at the same location where you get this FBB mini-HOWTO. This mini-HOWTO would be improved from time to time. If you think that the HOWTO on your Linux installation CD is some out-of-date, you may check for newest release on the Internet. It could be found within the main Linux Documentation Project homepage or this one: Linux Documentation Project . 12.4. Credits This version of mini-HOWTO can thanks to: Jean-Paul Roubelat, F6FBB, the author of FBB, Per Olsen, LA6CU, the author of FBB documentation, Jesus R., EB5AGF, the author of Protus, Jose Marte, HI8GN, the packager of 7.02g package, and a variety of helpful radio amateurs world-wide. Any comments or suggestions can be mailed to my email address: m.skoric@eunet.yu. 12.5. HOWTO These are intended as the primary starting points to get the background information as well as show you how to solve a specific problem. Some relevant HOWTOs are Bootdisk, Installation, SCSI and UMSDOS. The main site for these is the LDP archive at Metalab (formerly known as Sunsite). 12.6. Mini-HOWTO These are the smaller free text relatives to the HOWTOs. Some relevant mini-HOWTOs are Backup-With-MSDOS, Diskless, LILO, Large Disk, Linux+DOS+Win95+OS2, Linux+OS2+DOS, Linux+Win95, Linux+WindowsNT, Linux+NT-Loader, NFS-Root, Win95+Win+Linux, ZIP Drive, FBB packet-radio BBS etc. You can find these at the same place as the HOWTOs, usually in a sub directory called mini. Note that these are scheduled to be converted into SGML and become proper HOWTOs in the near future. 12.7. Local Resources In most distributions of Linux there is a document directory installed, have a look in the /usr/doc directory. where most packages store their main documentation and README files etc. Also you will here find the HOWTO archive ( /usr/doc/HOWTO) of ready formatted HOWTOs and also the mini-HOWTO archive ( /usr/doc/HOWTO/mini ) of plain text documents. Many of the configuration files mentioned earlier can be found in the /etc directory. In particular you will want to work with the /etc/fstab file that sets up the mounting of partitions and possibly also /etc/mdtab file that is used for the md system to set up RAID. The kernel source in /usr/src/linux is, of course, the ultimate documentation. In other words, use the source, Luke. It should also be pointed out that the kernel comes not only with source code which is even commented (well, partially at least) but also an informative documentation directory . If you are about to ask any questions about the kernel you should read this first, it will save you and many others a lot of time and possibly embarrassment. Also have a look in your system log file ( /var/log/messages) to see what is going on and in particular how the booting went if too much scrolled off your screen. Using tail -f /var/log/messages in a separate window or screen will give you a continuous update of what is going on in your system. You can also take advantage of the /proc file system that is a window into the inner workings of your system. Use cat rather than more to view the files as they are reported as being zero length. Reports are that less works well here. 12.8. Web Pages There is a huge number of informative web pages out there and by their very nature they change quickly so don't be too surprised if these links become quickly outdated. A good starting point is of course the Linux Documentation Project home page, or this one: Linux Documentation Project , an information central for documentation, project pages and much, much more. Please let me know if you have any other leads that can be of interest. 13. Getting help In the end you might find yourself unable to solve your problems and need help from someone else. The most efficient way is either to ask someone local or in your nearest Linux user group, search the web for the nearest one. Another possibility is to ask on Usenet News in one of the many, many newsgroups available. The problem is that these have such a high volume and noise (called low signal-to-noise ratio) that your question can easily fall through unanswered. No matter where you ask it is important to ask well or you will not be taken seriously. Saying just my disk does not work is not going to help you and instead the noise level is increased even further and if you are lucky someone will ask you to clarify. Instead describe your problems in some detail that will enable people to help you. The problem could lie somewhere you did not expect. Therefore you are advised to list up the following information on your system: Hardware · Processor · DMA · IRQ · Chip set (LX, BX etc) · Bus (ISA, VESA, PCI etc) · Expansion cards used (Disk controllers, video, IO etc) Software · BIOS (On motherboard and possibly SCSI host adapters) · LILO, if used · Linux kernel version as well as possible modifications and patches · Kernel parameters, if any · Software that shows the error (with version number or date) Peripherals · Type of disk drives with manufacturer name, version and type · Other relevant peripherals connected to the same busses Remember that booting text is logged to /var/log/messages which can answer most of the questions above. Obviously if the drives fail you might not be able to get the log saved to disk but you can at least scroll back up the screen using the SHIFT and PAGE UP keys. It may also be useful to include part of this in your request for help but do not go overboard, keep it brief as a complete log file dumped to Usenet News is more than a little annoying.
