Although Ubuntu is a fantastic Linux distribution they have done quite a few annoying things by default in a effort to create a more user friendly work environment. One of these things is the tool tips and descriptions which pop up whenever the mouse is hovered over anything.  This happens for links, applications, folders and pretty much everything else.

Recently I was doing a security audit on a Linux server and noticed some Apache and PHP items that needed to be modified to make the server more secure. One of the items that should be disabled is allow_url_fopen because the risk that it can be abused. The issue is that allow_url_fopen is on by default even though many times it is never used on a server. Modify the below line in the Linux servers php.ini file which typically located in the /etc directory.

I recently had a client who kept complaining that their office server was randomly rebooting through out the night. I knew when I had done the install of server 2003 I had turned off auto updates so that I could control the update procces myself but the problem sounded like auto updates. Once I did a little investigation I noticed that auto updates was still on and when I tried to change it via the control panel all the options were grayed out and I had no control. I then remebered that active directory’s group policy determines pretty much every thing on a domain controller and since I had just reused the existing policy when I did the reinstall, the automatic updates were still on.
In this article I will show how to turn off auto updates on a domain controller running active directory:
