Currently I have several cod2 servers in version 1.0, called dtN (destination eSports), they are top 10 in gametracker.

I would like to know how to change the name to: Unknown Soldier, when they connect to the server, For example: dtN_eSports:Fan#242.

How can I implement the code in my mod?

I would like to know the step by step for the implementation.

My servers run under linux server.
