I have one bash script under RHEL 5.3 to reconnect the VPN whenever
it's broken i.e.
############
if ! ps -C 'vpnclient' --no-heading >/dev/null 2>&1
then
echo "relink at $(date +%F\ %T)"
nohup /path/to/vpnclient connect ******* >/dev/null &
fi
#############
sometimes the ps command displays vpnclient OK but the connection is
stale, there is no actual connection until I run pkill vpnclient and
reconnect the VNP.
is there any way that I can detect if a connection is stale for a
certain time i.e. 120 seconds, and then run the pkill command in order
to re-establish the connection?
many thanks,
lihao
