How to Set Up OpenVPN on Linux

This stepwise tutorial will help you set up and configure the OpenVPN server and client for Remote Access.

Install OpenVPN

Install the OpenVPN app on both the server and the client machine.

$ sudo apt-get install openvpn

Use the respective package manager of the distribution that you are working. If you are using Yum, then do the following

$ yum install openvpn

Create Directories and Set Env Variables

Copy the easy-rsa contents in the directory created inside /etc/openvpn. By doing so the changes done to the scripts will not be lost whenever the package is upgraded. Change the owner to the current user so that it has permission to create files.

$ sudo mkdir /etc/openvpn/easy-rsa

$ sudo cp /usr/share/doc/openvpn/examples/easy-rsa/2.0/* /etc/openvpn/easy-rsa

$ sudo chown -R $USER /etc/openvpn/easy-rsa/

Then you can edit /etc/openvpn/easy-rsa/vars to adjust to your environment.



export KEY_CITY=”CHN”

export KEY_ORG=”tgs”

export KEY_EMAIL=”admin@beencrypted.com”

Create the CA – Certificate Authority

Establish a Public Key Infrastructure to enable server and clients to authenticate each other.

$ cd /etc/openvpn/easy-rsa/

$ source vars

$ ./clean-all $ ln -s openssl-1.0.0.cnf openssl.cnf

$ ./build-ca Generating a 1024 bit RSA private key



unable to write ‘random state’writing new private key to ‘ca.key’


You are about to be asked to enter information that will be incorporatedinto your certificate request.

What you are about to enter is called a Distinguished Name – DN.

You can leave a few fields blank, by entering ‘.’, the field will be left blank.

There will be a default value for some fields.


Country Name (2 letter code) [IN]:

State or Province Name (full name) [TN]:

Locality Name (eg, city) [CHN]:

Organization Name (eg, company) [tgs]:

Organizational Unit Name (eg, section) [changeme]:

Common Name (eg, your server’s hostname or your name) [changeme]:

Name [changeme]:

Email Address [mail@host.domain]:

After ./build-ca is done, you will be able to see a file namely ca.crt” and “ca.key” inside /etc/openvpn/easy-rsa/keys/.

Do keep in mind that the .key” file has to be kept confidential.

Creating Certificate for Server

Next, you can create a certificate for our OpenVPN server.

$ /etc/openvpn/easy-rsa/build-key-server vpnserver


Sign the certificate? [y/n]:y

1 out of 1 certificate requests certified, commit? [y/n]y

Note: The VPN server us the Hostname of that server and this command will be taking data from the user which is identical to the previous one. This command will help you create the certificate and key files for the server.

Create Certificate for Client

A certificate is required to authenticate the VPN client with the server. If you want to set up multiple clients then you need a certificate created for each client individually.

$ ./build-key vpnclient1


Sign the certificate? [y/n]:y

1 out of 1 certificate requests certified, commit? [y/n]y

Here, vpnclient1 is the Hostname of a particular client. This command will generate the certificate and the key files for the client.

Create Diffie-Hellman Parameters

$ ./build-dh

After the above steps have been completed successfully, you will have many key and certificate files inside /etc/openvpn/easy-rsa/keys.

Copy the certificates to the respective locations

Once you have created the Root Certificate (Certificate Authority), Server Certificate and Client Certificate, you need to copy them to the appropriate locations.

$ cd /etc/openvpn/easy-rsa/keys/

$ sudo cp ca.crt vpnserver.crt vpnserver.key dh1024.pem /etc/openvpn/

$ scp ca.crt vpnclient1.key  vpnclient1.crt root@vpnclient1:/etc/openvpn

By doing so, you have copied the client certificate and the key to the client machine. You should always use a secure medium like scp, while copying the key files.

Configure the Server

OpenVPN provides a default server.conf. You can alter it to adjust it to your needs.

$ sudo cp /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz /etc/openvpn/

$ sudo gzip -d /etc/openvpn/server.conf.gz

Edit the “/etc/openvpn/server.conf“.

ca ca.crt

cert vpnserver.crt

key vpnserver.key

dh dh1024.pem

Now you can start the OpenVPN server:

$ sudo /etc/init.d/openvpn start

* Starting virtual private network daemon(s)…

* Autostarting VPN ‘server’

$ ifconfig tun0


Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
