You only have to use a well known internal or external machine which will answer ping requests, i.e. 8.8.8.8 always responds to ICMP ping rquests. You can even check wether the internal connection works by choosing a well known internal machine. This way will make you sure that you either have an access to the intra or extra network or none.

The other replies about doing pings look good. About 15 years ago I wrote up an answer to this question: http://www.brenemanlabs.com/iConnect.htm My answer also has some clues for the old days when using a modem to call an ISP but pinging is discussed at the bottom. :) -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
