GH> Maybe check whether a particular port is open? unfortunatelly, there is no simple and universal answer. providers and administrators does many specific things, which valid only for their clients. for example, for a typical client it's enough to make an http protocol up and running. second, your "connected" is a very common thing. is your system connected, if your connect to provider is ok, but provider's network lies down? or provider lost connection to europe or US? basically, take a look at modules at http://search.cpan.org/search?mode=module&query=ping Things, which shows you, that system is NOT connected: 1. you can not reach your default gateway 2. you can not operate with your provider's DNS server(s) addresses of gateway and DNS servers you can obtain by running 'ipconfig /all' command on Win* boxes.
