Depends on who "you" are. If you are the end that is pinging, there is no way to know (putting aside fancy tools used by crackers, an area I'm not knowledgeable about). All a ping is supposed to tell you is that some host responds to that address, not any details of what host it is. If you are the end being pinged ... in the normal course of events, no records are kept of ping replies, you you are still out of luck. But if the server in question is running firewalling, you can set it to log icmp packets, which will let you know if the ping requests actually reach it. Or, on the firewall, you can log icmp packets that get forwarded. (At least these things are true of Linux servers and firewalls; since you don't say what OS your server is running, YMMV at that end.) -- -----------------------------------------------"Never tell me the odds!"-------------- Ray Olszewski -- Han Solo Palo Alto, California, USA [EMAIL PROTECTED] ------------------------------------------------------------------------------------------- ------------------------------------------------------- This sf.net email is sponsored by: Dice - The leading online job board for high-tech professionals.
