in thread Ping and check for server running on port 27015

AFAIK there is more than one way to do a Ping (mmmm sounds familiar)... Anyway, you can also use TCP Ack packets and Syn packets to "Ping" but they dont really fall under ya good ole' Ping :)

    And sending mangled/raw IP packets in this fashion is a "feature" unavailable to mortal users. You would need root or administrative privileges on the machines in question to perform this. Generally when somebody wants to "ping" another machine, it's an ICMP echo request/reply. If you want to test to see if the machine is responding to connection requests, simply try to make a connection. Sending out bare SYN packets and watching for responses is stuff you see packet kiddies doing, so you're quite likely to set off some intrusion detection systems.
      Well, I never said it was a normal way to ping :) In fact, I said "...but they dont really fall under ya good ole' Ping" :)
