Ever locked yourself out of your Server while making some iptables changes? What about when you change your SSH port and then forget what you set it to? These are common support tickets we receive at RackWire.com. In many cases this is something our customer’s can fix on their own if they are using cPanel on thier VPS/Server.

cPanel comes with a number of “hidden” autofix commands that allow for administrators to fix common problems simply be logging into WHM and going to a special URL. Two of the most useful ones I’ve seen are flushing iptables and restarting SSH in “safe mode” (basically the default settings and port).

Flushing iptables rules  http://yourdomain.com:2086/scripts2/doautofixer?autofix=iptablesflush

Restart SSH in safe mode  http://yourdomain.com:2086/scripts2/doautofixer?autofix=safesshrestart

Once you hit the URL you will be prompted to log in. Simply enter your root password and cPanel will do the rest. These have definitely saved me on more than one occasion when my attempt to ’secure’ my server worked a little too well.  Remember that if you happen to also lock yourself out of WHM through iptables, you will not be able to hit the URL’s I mentioned.  In that case, contact support.

Here are some other userful commands as well:
