I have a VPS with Centos and with firewall that I used to configure by Lxadmin. Now I don't have Lxadmin control panel and can't go to change it by web interface. How to discover what firewall I have on my machine and where is the config with blocked IP so I can remove mine?

Your own IP is blocked on the server?– grufftechMay 18, 2010 at 16:25

Administration panels are off topic. Even the presence of an administration panel on a system, because they take over the systems in strange and non-standard ways, making it difficult or even impossible for actual system administrators to manage the servers normally, and tend to indicate low-quality questions from users with insufficient knowledge for this site.– HopelessN00bApr 9, 2015 at 19:49

On CentOS, the default location for iptables rules are /etc/syconfig/iptables. If you want to whitelist your work IP, add this right after the -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT line:
-A INPUT -i eth0 -p tcp -s <YOUR_WORK_IP> -j ACCEPT
You can check for iptables by just typing the command
iptables
EDIT: ... can you get to a shell?

I'm currently trying to whitelist my work IP so I can get to my server at home. Going thru the /etc/hosts.allow, and my moblock whitelist. Just some other things that could block you.– Joe AAug 20, 2010 at 19:41
