my server working but can't login to it and i cant add it to Gametracker please help me .

I suggest that you contact your server provider for login assistance.

you have to open some ports in in the firewall iptables rules like ports of steam users (1200) , port of MYSQL (3306) , port of httpd (80), port of the server (27015) , if your server runing in centos 6 go to etc/sysconfig/iptables open the file iptables and add this :

-A INPUT -s 127.0.0.1/32 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT
-A INPUT -p udp -m udp --dport 1200 -j ACCEPT
-A INPUT -p udp -m udp --dport 27000 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 27020 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 27039 -j ACCEPT
-A INPUT -p udp -m udp --dport 27020 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
-A INPUT -d serverip/32 -p udp -m udp --dport 27015
-A INPUT -d serverip/32 -p tcp -m tcp --dport 27015 -j ACCEPT

then save the file and open SSH tool (putty) write service iptables restart this will 100% fix your login problem .
if gametracker can't scan your server take a look at this:
