This being System Administrator Appreciation Day, I'd like to give a shout out to all the people on ServerFault.com who help system administrators find the answers to their questions. If you are patient, understanding, and looking to help fellow system administrators, this is a worthy community to join.
I like to click on the "Unanswered" button and see what questions are most in need of a little love.
Sometimes I click on the "hot this week" tab and see what has been answered recently. I always learn a lot. Today I learned:
- that GRUB has the ability to have a "one time boot" option, that fails to a different boot option;
- how to diagnose a Windows server that doesn't show all RAM that is installed;
- the pros and cons of using your ActiveDirectory DCs as your internal DNS servers (there were some suprises);
- ways to recover from accidentally revoking all your Puppet certs;
- that there's a utility called AutoSSH which keeps tunnels open for you;
- and how to find and fix a problem with a Windows VM using a constant amount of CPU even when it should be idle.
ServerFault also has a chatroom Chatroom which is a useful place to hang out and meet the other members.
Happy Sysadmin Appreciation Day!
