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 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 it can 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.
Create the CA – Certificate Authority
Establish a Public Key Infrastructure to enable servers and clients to authenticate.
$ 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]:
Email Address [email@example.com]:
After ./build-ca is done, you can see a file, “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 take data from the user identical to the previous one. This command will help you create the certificate and essential files for the server.
Create a Certificate for the Client
A certificate is required to authenticate the VPN client with the server. To set up multiple clients, 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 critical files for the client.
Create Diffie-Hellman Parameters
After completing the above steps 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 must 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 essential 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“.
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
inet addr:10.8.0.1 P-t-P:10.8.0.2 Mask:255.255.255.255
