Sure, easy, you could use fetch to grab a web page and check it's return code. If it gets an error or times out it will probably return a code >0 (have to check the manpage). So something like this: #!/bin/sh fetch http://your-isps-site.com/ || kill-ppp-command > i am keeping a log of all the ip's i connect as so to > inform the provider of the malfunctioning modem line. The times are really important. When you have a bank of 100 modems it's virtually impossible to find bad modems without some seriously detailed data.
