That usually depends on what exactly you mean by "the network". If you're using diald or some such, take a look at the result of `route`. If the network is always "logically up" on your machine, but frequently not "physically up" you'll need to probe for a response from some remote system. Take a look at the man page for ping and read about the -c and -n options. You'll need to run grep on the result because the presence or absence of a remote host won't affect ping's return code. -- Raul
