Its reachability is quite definitive re: whether your ISP link is up or down. Even it it's assigned dynamically by DHCP, you should be able to write a script that pulls that IP, pings it a few times, and checks the result. No special tools necessarily required. -- Greg Barniskis, Computer Systems Integrator South Central Library System (SCLS) Library Interchange Network (LINK) <gregb at scls.lib.wi.us>, (608) 266-6348
