There's a file in the HL SDK that explains the protocol in detail, but I'll paraphrase it:
The client sends a UDP packet to one of the master servers (which are listed in a valvecomm.lst/woncomm.lst file) and the master server replies with a list of IP addresses which are running Half-Life servers. The client then sends a query UDP packet to the server, and that replies with details like the server name, active/max players, etc. and it works out from the time taken between sending the query and receiving a reply the ping of the server. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Vyacheslav Djura Sent: 04 November 2003 11:00 To: [EMAIL PROTECTED] Subject: [hlcoders] n00bish question Hello people, I'd like to know how Half-Life searches for active servers, running a game.
