I recently discovered Scamper: http://www.wand.net.nz/scamper/scamper-cvs-20070523i.tar.gz I use it to detect the maximum MTU size at each hop along a connection. Good for troubleshooting path MTU discovery problems. Having Netflow up and running on your network is an important tool, for problem diagnostics, performance measurement, forensics, billing, and more. Another handy tool is ngrep, like tcpdump but it only prints packets that match a particular pattern in the data. I'd also like to put in a word for tcptraceroute, which is like regular traceroute but via TCP so it can often give you extra information about hosts behind firewalls since the TCP packets make it all the way to the end host. _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
