I've never used it, but I can give you a few generic steps to take when you want to figure out what's going wrong with a connection. Are you familiar with tcpdump and/or ethereal? 1. Go to the computer of a client who is complaining about disconnection. 2. ssh into your gateway and run: # tcpdump -i eth0 host 123.123.123.123 and port not ssh Change "eth0" to the inside interface and "123.123.123.123" to the IP address of your client. 3. See if tcpdump is catching lots and lots of packets. If it is, either stop programs on your clients machine that access the Internet or use more filters (like "and port not imaps"). 4. Once you're not catching lots of extraneous packets, kill tcpdump and run: # tcpdump -s 1500 -w log -i eth0 host 123.123.123.123 and port not ssh Include any other filters you have to use. 5. Have your client start up their program, and then sit there and wait. Don't do anything else that would send packets through the gateway; you don't want to clutter up the log. 6. See if the problem manifests. Most likely it won't, because that's just the way things are :) , but if it does you'll have a log. Kill tcpdump and examine the file with: # tcpdump -r log If you want more verbosity, use "-v", "-vv", or "-vvv". Or, if you want to use a gui, copy the log file to some machine with X11 and use: # ethereal -r log -Corey _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
