[syslog-ng]syslog-ng fails to start if attempting to forward to unrouteable ip
05 Dec 2002 14:36:25 +0000
I have a box I am testing syslog-ng v1.5.23 on - its basically a
stripped Red Hat 7.3 box with a 2.4.20 kernel.
This box talks to other stuff via an IPSec (FreeS/WAN) link. At boot up
time, when the interfaces are originally bought up, the box has almost
no routes at all - it definitely has no default route. Following the
syslog-ng startup the ipsec startup script runs and brings up the
tunnels incidentally providing a default route.
The syslog-ng config includes remote logging of some of the information
to a central server - seen over the IPSec links. The destination part
of this is set as udp("188.8.131.52");
However the syslog-ng startup fails with an error - from memory it is:-
Error creating AF_INET socket - Network is unreachable
I'm not sure if a failing destination - especially where its a
network/udp one - should kill the complete daemon startup.
Also can people suggest a route round this?
So far the best that comes to mind is to make the remote logging run via
a program which buffers anything it receives and tries repeatedly to
send it until it manages to successfully sent it - but thats quite a
