More info.
I found a mistake typo in ax25route.c where i did not /* out */ a short line
else if ( /* cp->rejsent && */ (cp->reseq .....
im shure you know where..
well this did not fix the problem.
Im connecting with tests to db0dar the darmstadt Germany flexnet-dama digi
its almost impossible to get a ax25 trace as the system just stops as soon
as i get an I frame ?? well i think thats it..
i see my SAMB go out and the UA (dama) come back, at this poing it just
crashes the NOS.
again im thinking that there is a small part of the code in error
the dama processing of I frames. ?
any one else want to have the src code and help work on this bug ??
please email me an ill mail you the src's
some help please..
Thanks. Barry gm8sau/dc0hk

Subject: unexpected text connections
To: tcp-group@ucsd.edu
If I have a process accepting AX.25 connections with the expectation
that imbedded protocols (tcp/ip, net/rom, etc) will be passed up to the
next protocol layer, but I don't have a text stream listener waiting on
the socket, what should I do when streamtext comes along? Reply with a
'service not available' or 'no handler attached' message, and/or
disconnect?
Where this happens is when a naive vanilla AX.25 user connects to a
port that's not normally configured to handle vanilla streamtext
connections. Just tossing the packet on the ground is uncool; it
leaves the user wondering whether his equipment has died or what.
Or should an unattached streamtext socket become an echo server?
That is, the naive user would just get back everything he sends?
Suggestions?
