SuSE 7.3 System crash with FBB
Hallo, I have a big problem to get FBB running on my brand new SuSE 7.3. I used to run RedHat 5.2 for years without problems. When I start FBB my system completely crashes. Yes, the system - the complete PC hangs itself. Nothing responds and not even an Oops appears. I can not change between virtual consoles (outside X) and the only thing that is "moving" is a blinking caps-lock light. I have 2 modems on my system, a BayCom for APRS use and a YAM 9k6 which is used by FBB. Using "call" I can connect to the local BBS via the YAM modem, and on the BayCom I can see traffic. I have to use the full-duplex driver, I still have to sort out why. Furthermore there is an ax25-loopback to simulate access over the air towards FBB. I used the FBB supplied with SuSE but because that crashed I also compiled my own. The one I compliled was the very same version that had ran for years on RH 5.2 (only small patches to make it work with the new utils). FBB is not using the baycom. Not stating up BayCom doesn't make a difference, and even when I only use the loopback ond have switched off the YAM modem the crash will occur, albeit it takes a little longer. When I disable all kernel-AX25 interfaces FBB stays up, but that's pritty useless :-(. I hope somebody can help me, I use FBB as intermediate program between eMail/News and the local BBS. The local FBB does the forwarding and reception and MailGW passes it to sendmail and INN. Kind regards, Henk.

Hello Don, Thanks for thinking with me, but if it was that simple I would not have bothered the list. I have been running AX.25 trough the kernel for about 3 years now, with an 2.0.36 kernel, so this is not a problem (I am even the author of the HAM packages on the SuSE CD). Anyway, even if I made a complete mess of it, it should never ever freeze the machine (unless wrong IO adresses and interrupts were configured which is not the case). I suspect that the AX.25 stuff for the 2.4 kernel is not okay yet. I applied the patch to the YAM modem module by OK1ZIA to get rid of the "kfree_skb on hard IRQ" and the "Bad boy" kernel messages. It did not solve the problem. I noted that it is not an FBB problem. I have some home-made tools to do reverse forwarding to fetch bulletins. These run for a while but eventually also hangs the system. It seems to occur upon closing the connection or closing the socket, at least I saw it 3 times lockup exactly at that point. Thanks to a suggestion by Jean-Paul ROUBELAT (F6FBB) I tried the 2.2.19 kernel packaged with SuSE (I did not realize one was there, I already started thinking about downgrading). This seems to run just fine. Both FBB and my home-made tool stays up. So at least this is a bypass for now and also its pritty sure this is a kernel problem and not something else. I just compiled the latest kernel 2.4.15-pre6 from www.kernel.org (first tried 2.4.14 but the loop device did not compile, so I patched it with the latest patch). This is a bleeding edge kernel now. I'm still fighting with it as the new kernel cannot find the reiserfs module at bootup (yes, it is there, but maybe in the wrong place...). Anyway, no results from that yet (changes to the AX.25 parts compared to SuSE's kernel are minimal, so I don't expect much).

Hallo,
...
I hope somebody can help me, I use FBB as intermediate program between eMail/News and the local BBS. The local FBB does the forwarding and reception and MailGW passes it to sendmail and INN.
Kind regards,
Henk.

Hello Jean-Paul,
Van: "Jean-Paul ROUBELAT"
In another way, last versions of FBB (7.04g) now include a pop and news server.
Okay, thanks for the information! I like however dedicated programs since I bet whatever you build in, it doesn't beat INN, sendmail, Apache, FTPd etc. I also fail to understand programs like TNOS that build in everything that is already present in the system - and is much better (and better supported) in the Linux system. But everybody takes what sutes him best. But maybe I will try it out when I have some time because it will make the setup simpler. Our local BBS is still using DOS and we want to go to Linux there too, so maybe we can deploy this functionaly for that. I'm now running my own compiled FBB 7.00g ("ported" to the new ax25 libs) with everything contained in /home/fbb (everthing runs under the fbb userid, only xfbbd is SUID to root). With the new version the files are all-over the place so I have to sit down and see it is worth the effort. First I have to get Xastir running again (latest development version). I now run on the 2.2.19 kernel since the afternoon and have had no lockups since. The mailgateway runs and I saw my first message send with "mutt" pass via sendmail to FBB and handed over to the local BBS. So thats good. I hope somebody will fix the AX.25 stuff in the 2.4.x kernel. Kind regards, Henk.

For sure, I dont't claim to be even 50% under these software, but this is a simple implementation of a pop3 server (with APOP authentication), a news server and a SMTP server. This has been designed only for local users as a "packet/local ip" gateway

Yes, the versions after 7.0 are now following the installation rules and the files are "in their place". This is not realy easy at the beginning, but when anyone knows the linux organisation, it's OK. pass
via sendmail to FBB and handed over to the local BBS. So thats good. I hope somebody will fix the AX.25 stuff in the 2.4.x kernel.
I'm now running 2.2.20 since one week without any problem.
Kind regards,
Henk.

I know Joerg is working on this. I made some fixes in the rose layer of 2.2 kernel which are included in 2.2.20 but I must admit that I have few motivation (and many other things to do...). May be Joerg could tell us what is the actual level of his implementation for 2.4.x
Kind regards,
Henk.
