====== Loosing Gateway on freebsd 5.5 ======
I have not seen any solution so far, so following custom scripts will help you.
add following line to rc.local.
/usr/local/bin/netmonitor
create script netmonitor
#!/bin/sh
. /etc/rc.conf
netmonitor(){
while [ 1 ]; do
ping -c 5 -t 1 $defaultrouter
if [ $? -ne 0 ]; then
sh /etc/netstart
sh /etc/rc.virtual
fi
sleep 5
done
}
netmonitor &
==== OR ====
Following script you should run from the crontab.
#!/usr/local/bin/bash
gtway=24.24.222.25
ping -c 5 -t 1 $gtway
if [ $? -ne 0 ]; then
sh /etc/netstart
sh /etc/rc.virtual
echo "$date Gateway issue Detected" >> /var/log/messages
fi
