Re: Strange SEG Fault - need help on this one.
OK, you don't by chance have a different callsign/ssid on your VHF port, do you?? I'm thinking probably not, but I'm not coming up with much. 73, Lee K5DAT On Sun, Apr 27, 2025 at 11:52?AM Charlie Hein via <chein=[email protected]> wrote:

Re: linbpq seg fault
Hi, thanks John,
?
I've sent config directly to you for any comment/issue.
?
Excluded, got it. If it starts to crash again I will try this.
What's the difference between this excluded checkbox and the bbs checkbox on the same users page?
Is there a web doc to explain this page somewhere, I didn't locate it so far.
?
Still no crashes, still no update on the MH for n2mh - so that still seems inline with the issue being triggered by the new ax-ip UDP map set up.
?
Many thanks,
All the best, 73 de Louis / kd2yck

Brian,

Here are a few things to check/set.
?
Run raspi-config, check the serial console off, then serial port on.
?
remove power
(you can leave the sd card out)
turn pot R6 on the tnc all the way CCW and apply power .
yellow DCD LED should flash. (resets pi-tnc to factory defaults)
remove power
turn R6 clockwise 1/2 turn
put the sd card back in
apply power
?
change to the directory your running bpq from.
sudo setcap "CAP_NET_ADMIN=ep CAP_NET_RAW=ep CAP_NET_BIND_SERVICE=ep" pilinbpq
Replace pilinbpq with the program your running as the executable.
?
This should be a good place to start.
run htop to verify linbpq is active or run sudo systemctl status bpq
post the results.
?
Check the log files for clues if bpq is NOT active
?

Re: Strange SEG Fault - need help on this one.
Hi Lee - Yes, you're understanding it better than I said it <grin> - this is only happening when connecting on the VHF port, and connections to the Chat and node aliases work just fine, but the BBS dies when called from the node menu when the connection was made on my VHF port.? I'm running Version 6.0.24.69 - once I discovered it, the first thing I tried after reviewing my configs was to update the version.? That wasn't the problem as it turns out.

? Are you referring to only incoming connections on VHF?
I think based on the above you are talking about incoming connections. Are you saying that an incoming connection over VHF directly to the BBS alias or call will cause the segfault, AND if an incoming connection is made first to the node, then to the BBS, the segfault happens upon attempting to connect to the BBS? What version of BPQ are you running, and did the problem start after upgrading to a newer version? 73, Lee K5DAT

Strange SEG Fault - need help on this one.
Thanks in advance for your attention.? I'm really stumped by this one.
?
My BBS will die with a SEG fault at connect over my VHF port, but NOT when called over the internet (AXIP port) or from the keyboard.? ODDLY, the RPi does NOT SEG fault when called over the air on any other aliases, but if the BBS is called from the node alias, the RPi will immediately die of a SEG Fault as it does if called directly.
?
Any ideas?

Re: linbpq seg fault
Hi Glenn,
?
Thanks for the message and info. Very Interesting.
I am not fully up to speed on forwarding - but when I checked my node's config I did have a rule for n2mh
it was something very simple, like this:
c 2 n2mh-7
(port 2 was vhf radio direct link, our nodes are near each other) - but in order to rule out I have removed it for now...
Once all is stable I can try put something back in, perhaps more like (or same as) what you have shared there.
Thank you, this is invaluable reference.
?
Hopefully addressing all these areas, this will all fall in to place, can't see why it won't all work as expected unless we've found a bug to fix, but I suppose it can most likely be addressed as a config/setup issue, I hope.
?
All the best, Louis

Re: linbpq seg fault
Hi,
?
>I don't recognise the messages - do they mean anything to you?
I'm not quite sure - only significance is that is Mark's node, the new link we were adding in.
?
>It looks like the AXIP link is somehow getting connected to the BBS. Do you see in Incoming Connect message for N2MH-8?
Where would I see this? Could there be a problem with ssid suffix routing or forwarding, or some forwarding loop even?
?
>I would be interesting to see if excluding N2MH from the BBS allows the BBS to run.
Good idea, I presume that's just uncheck bbs from users page for n2mh for a bit and see what happens
?
>Could you also send me your bpq32.cfg so I can see if I can see anything that could be a problem?
Sure - what is best way to share it all, I do not want to compromise any station's ip/dns unwittingly. Should I email you it privately?
?
>The .mes files just contain the message contents, not the To, From, Subject etc.
Noted - lesson learnt, if I do this again ever I'll also back up the metadata file. If it had lived in the dir with message files that would have been fine, did not realise it was separated.
?
I currently have the node running, no crash in last 5-10mins, but also MH for n2mh* is still stale - I wonder if it will crash once that starts communicating again (assuming Mark still has map for my node in it).

All have been in place and working fine for some time (months/years) but the last n2mh is the new one added since yesterday and coinciding with crashes.
As you can see, all is AX-IP UDP, AX-UDP, all on same UDP port.
?
The only other thing I can think of at this time is there was a forwarding to N2MH in the forwarding rules, it was like this: c 2 n2mh-7 (port 2 is vhf direct link) - but to eliminate this I've removed this forwarding rule for now. Once stable this can be reinstated correctly as required. Not sure if these can have been causing issues?
?
I'm no expert on all of this, relatively new to it, so input from yourself as the author and other experienced packeteers is invaluable. Also, I am learning in the process :)

I think that this post has evolved into two separate issues.
?
1. Problems with bringing up a link between my jnos system and KD2YCK's bpq system.
2. A forwarding problem at WW2BSA.

As N3MEL can agree, his link works Ok.
?
I would point out that I have set this up as an AXUDP link, not an AXIP link. Terminology is very important here. AXIP and AXUDP are separate technologies and will not talk to each other.
?
I also run a second bbs system 600 miles away using BPQ software that links to the same jnos machine, this time over 44-net. This is the map statement for that machine along with the matching jnos configuration

Note that the UDP port can be changed. The only requirement is that both ends must agree. In this case, they do agree and the link works satisfactory.
?
For the record, hostnames and ip addresses have been changed to prevent tampering.
?
While it's possible that YCK's problem may be due to something that I am doing, I think that possiblity is remote. I use the same basic configuration very successfully for other forwarding partners.
?
As for WW2BSA, he is trying to send me a personal message, the same personal message, for the past several days. His machine does not seem to recognize the BID rejection being sent back to him. I don't want to hijack this thread with someone else's issue. So, that's all I'm going to say in this thread. I will say that I can stop the repeated forwarding attempts by going into his BBS and killing the message.

While it's possible that YCK's problem may be due to something that I am doing, I think that possiblity is remote. I use the same basic configuration very successfully for other forwarding partners.

As for WW2BSA, he is trying to send me a personal message, the same personal message, for the past several days. His machine does not seem to recognize the BID rejection being sent back to him. I don't want to hijack this thread with someone else's issue. So, that's all I'm going to say in this thread. I will say that I can stop the repeated forwarding attempts by going into his BBS and killing the message.

Re: linbpq seg fault
N2MH-8 is a J-Nos system, those errors I believe are coming from his side. I was watching that port yesterday and
WW2BSA looked like he was having the same problem.
?
I forwarded with Mark a number of times yesterday and again today BPQ to J-Nos with no issues.?
?
Louis I am not sure how your setup to forward to Mark's system but here is my forwarding script for him.?

Re: linbpq seg fault
¿ªÔÆÌåÓýHi Louis,I don't recognise the messages - do they mean anything to you? It looks like the AXIP link is somehow getting connected to the BBS. Do you see in Incoming Connect message for N2MH-8? I would be interesting to see if excluding N2MH from the BBS allows the BBS to run. Could you also send me your bpq32.cfg so I can see if I can see anything that could be a problem? The .mes files just contain the message contents, not the To, From, Subject etc. 73, John On 26/04/2025 22:22, Louis Botterill

Re: linbpq seg fault
Hi John, thanks very much!

I do see a lot of these in the logs, I think from when the new axip UDP link is started up

many times over

The ^M is a line endings, could that be an issue?
?
Interestingly n2mh is the new remote node I was hoping to link with...
?
When I traced some seg fault file line numbers to code it did see to be in a line endings area.- could it be forwarding many messages to me over new link we're trying to set up and causing a crash, due to some invalid / incompatible message content?
?
Shame about the DIRMES.SYS, I see a few backups but all super recent, alas. Shame - oh well. Is the format of dirmes.sys binary, I'd have no chance to make a small script to recreate from the mes files?
?
All the best, Louis

Re: LinBPQ error & exit
John,
toggle quoted message

Up to now, it seems to me that it crashes only when KAM port is used to initiate (or receive) a g-tor or pactor connection to/from the other station (UT1HZM, who also runs a KAM). It sometimes crashes after a session fails and disconnected, or an outgoing call was initiated but did not get response from the other party. It also looks to me that KAM does not fully returns to a TOR standby after the last link was over or failed, so it does not respond to a subsequent incoming connection request from the other party (even when the signal from the other end is loud & clear).

Does it crash randomly or only when you do something with the KAM? |
