Right, a script would bring the interface down. What if I need the interface back up as soon as the link is up. In this case my script would have to ifconfig my interface up every minute or so, then ping and wait for a reply ,if no reply receved, bring the interface down. May work, although not sure if flaping the interface up and down hundreds of times per day will not crash my FreeBSD router. Cisco's would sense no carrier on the 10baseT port and pring the interface down. On Thu, 2 Sep 1999, Joe Pepin wrote: > Hello, > > Yes, it seems to me you need a "hearbeat".
