[AMXX] [FIX] How to protect from steam id changer

How to protect from steam id changer in cs 1.6 server

Exploit:
when i was having server, hacker used different method to get password
He invite my admins to his server and steal his password using rcon
For steam id he used steam id changer at the time i don't know much about this stuff how he did :O
Also he claimed at Gametracker and reset my server rank but i gain that rank within week

Solution:
open dproto.cfg and search steamidhashsalt
>>First way
put steamidhashsalt [if hacker set the steam id then it will change steam id]
(Salt string for SteamIDs hashing. Irreversibly changes SteamIDs. Applies only to SteamIDs generated by emulators.
it Should be more than 16 chars length. If string is empty, hashing is not applied.)

SteamIDHashSalt = avbd26ja22gra1ma

>>Second way
step 1:change the steam id prefix
steam_0:0:123214321 to steam_0:4:123214321
