Recently we installed a development server running 64-Bit (x86_64) CentOS Linux. One of the things we needed to install was Python version 2.6 without overwriting the default Python version 2.4 on the server. The reason for not wanting to overwrite the default Python version is because other packages such as the Yum Package Manager depend on Python version 2.4. Anyhow in the past I have used the CHL repository for the Python version 2.6 packages because they are compiled to run as python26 or python2.6 and using the python command still launches python 2.4. Anyhow after installing the CHL yum repository as noted here we had issues installing python version 2.6 which I describe below along with how to resolve the issue.
I use tshark sometimes to strip down packet captures based on specific variables and needed to install tshark on a CentOS Linux server I recently built for various development tasks. The problem is that when attempting to install tshark using yum it returned an error because there was no package named tshark available in any of the yum repositories I had configured.
I recently installed Windows Virtual PC on my Windows 7 laptop and so far really like using it for virtual machines. One thing that I needed to change after the initial installation was to assign more available memory to the virtual machine which I initially thought I could do from within the XP Mode virtual machine as displayed in the below image.
I rarely use CentOS as a desktop but purehate and myself set up a development box the other day to test some things. We needed the computer to not only function as a Linux server but also as a Desktop for some of the items we wanted to test. In doing so I have been playing around with various items and I find myself needing to open terminal windows on a regular basis so I wanted to know what the keyboard shortcut was to open a terminal window. The quick answer is that there is not a keyboard shortcut to open a terminal window by default on CentOS running the Gnome desktop environment. Below are some quick steps to add a keyboard shortcut to open a terminal window on a computer running the Gnome Desktop environment.
I have been playing around with building RPM packages today on CentOS because I needed to upgrade curl and the latest version available on CentOS didn’t have the features I needed to use. One of the things that had come h up during the RPM build process and the RPM package installation process using yum was the fact that your RPM packages should be signed. Signing RPM packages gives them some validity and will allow others to install them without having to modify their yum.conf file. Below I describe how to generate a GPG key to be used to sign RPM packages created using the rpmbuild command. First below is a message that will be received when attempting to install unsigned packages using yum with the default yum configuration.
