If you're a bit into perl, you could periodically do a ping -c <count> to your default gateway, grep the last line from the ping output, like: 5 packets transmitted, 1 packets received, +5 errors, 80% packet loss Use a regexp to extract the 80% from the line and output it to a graph with mrtg and/or call a mail client or sms client to notify you if the packet loss exceeds a treshold. Shouldn't be too difficult :) Serge Maandag. -----Original Message----- From: Ralf G. R.

Well, I'm already using it since more than a year, but it's not exactly what I want. With MRTG I don't see if the line drops out for just a few minutes or so. Even if it drops out for a longer period it's sometimes hard to recognize. What I want is "something" that clearly indicates "line disrupted," that optionally notifies me immediately when this occurs, that also notifies me if excessive ping times occur, etc. Is such a thing available?
