Big A$$ Backups to Removable Media

Ever asked to backup a boatload of files to DVD?  Been stymied time after time adding just one too many files to a folder and it won’t fit on DVD/CD?  Enter Capacity.  A tool to break up that big job into just the right size chunks saving you time and heartache!

You are ready for DNSSEC right?!?!?

If you’ve not heard, time is growing short.  A massive rollout of DNSSEC will begin next week.  Learn more about it here.  I’m sure the change won’t be seamless and it will probably slow name resolution for awhile.  Might  be a good time to start reading if you haven’t begun already….

SELinux Issues

I had a few issues on a CentOS box today that I upgraded from 4 to 5.  Syslog wouldn’t start if SELinux was in enforcing mode.  I had to do a filesystem-wide relabel to get it all working.  It was pretty straight forward to do but here was the procedure that worked for me.

1. First make sure SELinux is up to date with a yum update
2. Put SELinux into Permissive mode (setenforce 0)
3. Now set it so that it won’t turn on after a reboot by editing /etc/selinux/config and setting the line SELINUX=permissive
4. reboot (not sure this is required but I did)
5. set the system to autorelabel (touch /.autorelabel)
6. now reboot again (this one is required and it may take a little while if you’ve got a big filesystem)
7. now run setenforce 1 and edit /etc/selinux/config and set it back to SELINUX=enforcing

That was pretty much it. A “service syslog restart” got it all going again. 

I’m still learning about SELinux.  Here is a great PowerPoint on it.

Windows 7 GodMode Folder

Happy New Year!

As you can tell I’ve been on vaca for a few weeks so I haven’t posted much.  I’ve been reading up on Windows 7 so I’ll be releasing some of what I’ve found over the next few updates. As I this is my first day back to work in two weeks I’ll keep this one simple.  You may have seen this around the net already but I thought it was kinda cool.  In Windows 7, there is the ability to create a “Control Panel-like” folder that has all the admin stuff that seems awfully hard to find in the new “forced” view of control panel. (I say that because the took the damn classic view of control panel completely out of Windows 7.  Damnit.)  Anyhow on any drive create a new folder and call it:

GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}

Now when you access that folder the goodies inside let you have a central location to go find a bunch of admin goodies.

Enjoy!
