Hi,
Our VPN runs okay for some time, and every now and then one of the links (we
have three hosts connected redundantly) just falls out with no reason. In the
syslog I get several (strange?) messages:
Feb 14 09:56:02 ophar tinc.pirnet[2816]: 212.187.121.188 port 655: Connection
timed out
Feb 14 09:56:02 ophar tinc.pirnet[2816]: Could not set up a meta

Feb 14 09:58:22 ophar tinc.pirnet[2816]: Bogus data received from unknown

Could someone give some commentary on those messages?
TIA

Could you do: ls -lR /proc/`cat /var/run/tinc.pirnet.pid` when this happens again and tell me what you see? If you see really lots of sockets in that directory listing then perhaps we've got a filedescriptor leak. If not, my next best guess would be that your kernel runs out of memory... Could you tell me which version of tinc and the kernel you are using, and on what hardware you're running this? ------------------------------------------- Met vriendelijke groet / with kind regards, Guus Sliepen <guus@sliepen.warande.net> ------------------------------------------- See also: http://tinc.nl.linux.org/ http://www.kernelbench.org/ ------------------------------------------- -------------- next part -------------- A non-text attachment was scrubbed...
