Server

Git is yet another open source version control, and seems to be the tool of choice for contemporary coding mavericks. I still prefer svn and cvs, for centralised version control, but can appreciate why some projects may require distributed repositories as afforded by git.

Setting up a central git repository on a server is easy. You basically setup a user, whose home directory is used to store the repositories, and allow access to people using keys, where the user retain their private key and their public key is saved as an authorised key for the git user account.

This post is just an update of a previous post that used CentOS 5.7 and OpenVPN 2.2 (http://nkush.blogspot.com.au/2011/10/installing-openvpn-22-on-centos-57.html). The basic instructions are the same, however this post uses some newer packages which may have been relocated to new URLs. Again this blog and the posts are mostly for my own reference and not intended as step-by-step instuctions for other systems/network administrators

Install RPMForge or RepoForge as it’s now known[1]

OpenVPN is an SSL based VPN. There are other VPN solutions such as IPsec, etc. but OpenVPN provides a cost effective alternative. I like OpenVPN as it support two-way authentication, i.e. both the client and server authenticate using certificates. To install OpeVPN on CentOS we need a number of cryptographic libraries. The simplest way is to use the DAG/RPMForge repository.

Set-up the RPMForge repository [1], as this contains the packages necessary for the installation and the instructions are provided below. The instructions below are just to document this specific installation and therefore this blog post is not to be misinterpreted as a best practises guide. The instructions are adapted from the OpenVPN website [2], but this blog post is intended more as a quick and dirty guide to getting OpenVPN running on CentOS 5.7. Additionally the set-up and configuration of the client is considered beyond the scope of this blog post.
