OpenVPN

Installing OpenVPN

OpenVPN can be downloaded here.

For security, it's a good idea to check the file release signature after downloading.

The OpenVPN executable should be installed on both server and client machines, since the single executable provides both client and server functions.

Linux Notes (using RPM package)

If you are using a Linux distribution which supports RPM packages (SuSE, Fedora, Redhat, etc.), it's best to install using this mechanism. The easiest method is to find an existing binary RPM file for your distribution. You can also build your own binary RPM file:

rpmbuild -tb openvpn-[version].tar.gz

Once you have the .rpm file, you can install it with the usual

rpm -ivh openvpn-[details].rpm

or upgrade an existing installation with

rpm -Uvh openvpn-[details].rpm

Installing OpenVPN from a binary RPM package has these dependencies:

• openssl


• lzo


• pam

Furthermore, if you are building your own binary RPM package, there are several additional dependencies:

• openssl-devel


• lzo-devel


• pam-devel

See the openvpn.spec file for additional notes on building an RPM package for Red Hat Linux 9 or building with reduced dependencies.

Linux Notes (without RPM)

If you are using Debian, Gentoo, or a non-RPM-based Linux distribution, use your distro-specific packaging mechanism such as apt-get on Debian or emerge on Gentoo.

It is also possible to install OpenVPN on Linux using the universal ./configure method. First expand the .tar.gz file:

tar xfz openvpn-[version].tar.gz

Then cd to the top-level directory and type:

./configure
make
make install

Windows Notes

OpenVPN for Windows can be installed from the self-installing exe file on the OpenVPN download page. Remember that OpenVPN will only run on Windows 2000 or later. Also note that OpenVPN must be installed and run by a user who has administrative privileges (this restriction is imposed by Windows, not OpenVPN). The restriction can be sidestepped by running OpenVPN in the background as a service, in which case even non-admin users will be able to access the VPN, once it is installed. More discussion on OpenVPN + Windows privilege issues.

OpenVPN can also be installed as a GUI on Windows, using Mathias Sundman's installation package, which will install both OpenVPN and the Windows GUI.

After you run the Windows installer, OpenVPN is ready to use and will associate itself with files having the .ovpn extension. To run OpenVPN, you can:

• Right click on an OpenVPN configuration file (.ovpn) and select Start OpenVPN on this configuration file. Once running, you can use the F4 key to exit.
  

   

  
  
  


• Run OpenVPN from a command prompt Window with a command such as:
  

   

  
  

  
  

  openvpn myconfig.ovpn

  
  

  
  

  Once running in a command prompt window, OpenVPN can be stopped by the F4 key.

  
  


• Run OpenVPN as a service by putting one or more .ovpn configuration files in \Program Files\OpenVPN\config and starting the OpenVPN Service, which can be controlled from Start Menu -> Control Panel -> Administrative Tools -> Services.
  
  

   

  
  

A GUI is also available for the Windows version of OpenVPN.

Mac OS X Notes

Angelo Laub and Dirk Theisen have developed an OpenVPN GUI for OS X.

See also OpenVPN Client and Mac OS X 10.3.

Other OSes

Some notes are available in the INSTALL file for specific OSes. In general, the

./configure
make
make install

method can be used, or you can search for an OpenVPN port or package which is specific to your OS/distribution.
