A quick script would be
#!/bin/sh
while (1)
do
ping ping -c1 isp.domain.com > /dev/null 2> /dev/null
sleep 240
done;
It will ping you ISP every 4 minutes. If you want to kill it, use a ^C
You should check to make sure you have the your ppp connect up before trying
to ping anything, and then modify anything that is Red Hat specif.
