repochk

repochk is a set of scripts to test if a system has packages with version numbers different then that of the official mirrors. This is useful for finding out-of-date packages, packages with a future version number, and packages which are not from the official mirror.

Requirements

You will need a system with internet access to update the mirror cache. Nothing is required to be installed on the system being tested. The following are required to run the other scripts.

• wget
• gzip
• Python

Running

1. On the machine you wish to check run getrpms.sh. This will create rpmlist.txt. This script does not need internet access to run. If you are testing an offline system you will need to transfer rpmlist.txt to a system with internet for the next steps.
2. Run update_repo.sh which will download the CentOS mirror list and output it to repocache.txt.
3. Run repochk.py, output prints to the screen

How it works

The latest version string for each package in repocache.txt is extracted. Then each package from rpmlist.txt is compared against the latest in the repo.

The version strings to compare are split into sections, they are split on two characters - and .. Each section is iterated and converted to an integer if possible. If both sections are integers then they are compared based on that. If they aren't integers a string compare is used. If one string has more sections and they have been equal up to this point, the longer one is considered larger.

Example

$ ./repochk.py

           ."""-.
          /      \
          |  _..--'-.
          >.`__.-"";"`
         / /(     ^\
         '-`)     =|-.
          /`--.'--'   \ .-.
        .'`-._ `.\    | J /
       /      `--.|   \__/
