Installing and Configuring OpenVPN 2.3 on Microsoft Windows Small Business Server 2003

My previous posts(http://nkush.blogspot.com.au/2012/08/installing-openvpn-22-on-centos-63-64bit.htmlandhttp://nkush.blogspot.com.au/2011/10/installing-openvpn-22-on-centos-57.html)have been on installing OpenVPN on Linux.

Installing Snort 2.9.1.2 on CentOS 5.7

CentOS 5.7 uses an older version of libpcap (0.9.4), but Snort’s DataAcquisition Library (daq) needs a newer version of libpcap (>=1.0.0).The latter is not an issue with the CentOS 6.0. Vishesh Kumar [1]provides an excellent instructions to getting Snort 2.9 to run on RHEL 5(http://www.linuxmantra.com/2010/10/install-snort-29-on-rhel-5.html).The purpose of this post is not to duplicate his efforts, but to extendit slightly to include instructions for a complete Snort set-up.
