Installing OpenVPN server on CentOS Linux (part3)
Server configurations for Debian and CentOS Linux are almost identical, except for the beginning of the installation process.
Since the package is not included into the CentOS repository, you will need to enable RPMforge (http://rpmrepo.net/RPMforge) to install OpenVPN.
Run the commands:
wget -ivh http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.i386.rpm
rpm -Uvh rpmforge-release-0.5.1-1.el5.rf.i386.rpm
The repository will be installed, and you will be able to install OpenVPN using the command
yum -y install openvpn
Copy the files (key utilities) into the folder of the openvpn configuration file
cp /usr/share/doc/openvpn-2.0.9/easy-rsa/2.0/* /etc/openvpn/
and set access privileges for the following files:
chmod +x clean-all build-ca build-key-server build-dh build-key /etc/openvpn/whichopensslcnf ./build-ca
Create the keys
Copy the openvpn configuration file
cp /usr/share/doc/openvpn-2.0.9/sample-config-files/server.conf /etc/openvpn/
Configuration is similar to that used for Debian; you will need to provide other settings, for example configure NAT.
Configuring the client OpenVPN on Windows Vista
We recommend using OpenVPN GUI for Windows http://openvpn.se/ as the client software
Download the openvpn-2.0.9-gui-1.0.3-install.exe file from the official website and install it leaving the default parameters.
Once finished, copy the client.ovpn file form
C:\Program Files\OpenVPN\sample-config\ into c:\Program Files\OpenVPN\config\
and paste the certificates’ files from the server
In the client’s client.ovpn configuration file change
remote my-server-1 1194
into the line that refers to your server’s address, for example,
remote 18.104.22.168 1194
and specify other certificates’ names
If you wish to connect to the Internet through the OpenVPN-server, you will need to add the following lines to modify the routing
Run OpenVPN as administrator – Start -> Programs -> OpenVPN –> double-click OpenVPN GUI and start it as administrator to apply the cahnges.
Double click OpenVPN GUI and choose Connect
Congratulations! You have successfully installed the client software.
