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. Its seriously annoying for a seasoned Linux user so I embarked on a quest to disable it. Fortunately its very easy.
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.
Installing a bunch of packages on a CentOS server today I ran into an issue where the CentOS Base mirror I was using was incredibly slow. First I checked to make sure that the yum-fastestmirror plugin was installed which it was. Next I attempted to clear the fastest mirror plugin cache by running “yum clean plugins” but I ended up with the same exact CentOS Base mirror yet again. Follow the directions below to disable a specific mirror from yum.
We have a site that does automated tasks using GPU processing however at times we use the GPU processing for other tasks which requires us to disable access to the public. The easiest way to do this is to install a WordPress maintenance mode type plugin that will allow you to easily disable access to the public but not require much work. Having a site in maintenance mode is also beneficial for any major site changes that may prevent a bad customer experience when visiting your WP site. Below are instructions on installing the WP Maintenance Mode plugin as well as information on putting your site in maintenance mode and bringing it out of maintenance mode.
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:
