Install Newest libpcap Version On CentOS Linux

Insights20 Comments

Earlier this evening I needed to install a newer version of libpcap on a CentOS Linux server. The current version available via the yum package manager is libpcap version 0.9.4-15 and I needed something newer than libpcap version 0.9.7. I ended up not being able to find a yum repository or RPM package that included a version newer than 0.9.4-15 so I decided to upgrade to the latest stable version of libpcap currently available which is libpcap version 1.1.1. Below are directions on downloading libpcap, installing it, and then verifying it is installed.

While creating a development environment for a Ruby project earlier I ran into an error installing some of the gems required by the project. I realized that I had installed an older version of RubyGems which was causing problems with some of the gem dependents that needed to be installed. Below I list one of the examples of the errors I was running into and how I resolved the issue.

Earlier when attempting to install the request-log-analyzer gem on a CentOS Linux server I ran into some issues. I noticed that on one server I was able to install the request-log-analyzer gem without issue but on another server running the same version of CentOS and Ruby as the first server the attempt to install request-log-analyzer returned an error. The error was that the gem required a newer version of another gem.
