How to Configure yum-updatesd to Notify By Email

On most new CentOS server installs yum-updatesd is installed by default and by default it sends notifications to the dbus. You do however have the option to configure it to send updates via email or to syslog. If you do decide to have updates sent via email then you will need to add a couple more configuration options to /etc/yum/yum-updatesd.conf which are email_to and email_from. Listed at the bottom of this post is the default configuration file followed by a yum-updatesd.conf file that will send email notifications of new files.

Another thing to watch out for is yum-updatesd locking your ability to update files via yum. While it is checking to see if there are new packages available it puts a lock on using yum so if you run into this problem you either want to remove yum-updatesd or set its configuration to not check once every hour. I changes my default to 10800 seconds or 3 hours.

WordPress Blog With Mandigo Theme Not Displaying Via Firefox

As you can see we have the Mandigo theme installed for this WordPress blog. Earlier today I was doing some testing I and noticed the site was not displaying when trying to view the site with FireFox version 3.0.1 which is the newest release at this time. I was running Mandigo version 1.36.2 and a new version (Mandigo 1.3.7) had been released so I decided to start my troubleshooting by upgrading. After the upgrade the problem still existed so I had to dig deeper.

I went through all sorts of steps to locate the issue but ended up contacting Tom at the creators of Mandigo and he provided a resolution. He thinks that Google may have changed the Adsense code thus causing the problem with Mandigo and Firefox. The true issue is not with Mandigo but with Google Adsense ads JavaScript conflicting with jQuery use in the Mandigo Theme. The fix was to replace code in the Mandigo theme footer.php as follows.
