Call this every n minutes with cron

   ----- test-link begins -----
#!/bin/bash
#
# Checks link to gateway to see if it's still up
# Note: ispgate defined in /etc/hosts
#
export result=`ping -c 4 -q ispgate | grep avg | wc -l`
if [ $result != 1 ]
 then
   echo `date` Attempting reconnection to ISP >> /usr/adm/connection.log
   /usr/sbin/isp-connect     # script that dials ISP
fi
   ----- test-link ends -----
