Look at 'man ping'. Try something like:
ping -n -i 300 some.host.some.where.in.ca
which will ping the named host every 5 minutes. If your ISP gets
clever and disallows ICMP Echo packets (i.e. ping requests) from
resetting their timer, use rsh to run this command on *their* system;
the output packets coming back to you will look like any interactive
session and will fool their watchdog.
