[nos-bbs] Raspberry Pi Jnos exiting every 15 minutes or less

Thu Feb 13 21:37:59 EST 2014

Thanks Bob for your help.

I disable the Respawn and run it from the shell.  This afternoon tested it in the office and Jnos stay alive for 4 hours without exiting until I exit and went home.  At home now, the status command show is up for 2 hours, 19 minutes, and 30 sec.

Something is wrong with the way I automatically restart routine in case of crash.

In /etc/inittab added this line:

##Start Jnos on bootup and respawn it should it crash
JNOS:2345:respawn:/jnos/startnos

My startnos:

#!/bin/sh
# Script to invoke the Linux Jnos.  Usage: dojnos [optional_args]
# User should edit definitions for jnosroot and autoexec, and edit the
# $local and $remote addresses, and $mtu value in the DIP script below:
#
rm -f /jnos/spool/mqueue/*.lck 2>/dev/null
rm -f /jnos/spool/mail/*.lck 2>/dev/null
#
exec /jnos/jnos -d /jnos -v </dev/tty8>/dev/tty8 2>&1
#

So maybe something wrong with tty8 or should I try another tty?

Or if there is another way to autostart Jnos in the RPI?

Now, that I monitor my log more frecuently to try to solve my problem.  I see that hackers are trying to hack into my Jnos.

  Check or /var/log/syslog gives you a clue just before the time it restarts.

  Run jnos from the shell prompt instead of in a pseudo tty  and let it run for a while
  and see or it doesn't crash or whatever.

  It may be how you start jnos in a pseudo tty if it keeps running from the shell.

My only problem is Jnos that is keep exiting in every 15 minutes or less.  I set it to respawn automatically.   I tried jnos2f and jnos2fx4 compiled from the source OK but still exiting.  The logs doesn't show me why it is exiting.

    I tried gdb but it said no debugging symbols.  I re-compiled the jnos binary without stripping but still shows the no debugging symbols.  I tried in the makefile debug static -g3 but does not compile and exit with Error.

    I tried looking at the autoexec.nos for anything not right, the network configuration, shorewall firewall configuration, cron jobs, not running the other software LinBPQ, APRX, etc but still exiting in 15 minutes or less.

    Any help where to look or what to try to make JNOS work.

    Thanks,
    Jose / HP2AT
