Call of Duty: Modern Warfare 2 on the PC does have a config file with settings that are modifiable. You can open the config file in notepad and edit away. Don’t remove anything or add extra lines or your game will crash. It’s also against your legal terms of use psycho-babble i’m sure.

I still prefer a flat ascii file either loading the rules one at a time, or the built in iptables save/restore which basically does the same thing. But if you like/want/need a GUI application, then skip the lokkit firewall configuration tool in favor of system-config-firewall. It makes configuration of your firewall as easy as the simple Windows firewall, but with the option detail you expect from Linux.

If you’re behind a proxy and you run that, you’ll get something like “the other end hung up” or “Cannot get remote repository information” because git is trying to connect using port 9418 by default. I found a few sites saying all you need to do is change git to http in the url and it will work, but that did not work for me. But it’s an easy fix. Change git’s http.proxy and you’re done. Here’s how: (replace my proxy host and port 8002 with your own)

Check the current config of a Qlogic HBA easily by looking under proc. I was stumped on one system for a few minutes because I couldnt get to the .conf file or modinfo. All I really wanted to check at the time was that the driver version loaded on each host was the same. Then I was going to find SAN surfer to find more info… I guess you could get most of this info from dmesg | grep qla, or modinfo qla2xip or whatever.
