You probably will get better response on ServerFault, but I'll answer anyway. OpenVPN is a client application and you need to install it on the device you want to use for your VPN connection. That device needs to have an IP address configured on the network which you are using for the VPN connection. You could set this up by adding an entry in /etc/hosts, or setting an IP address (by DHCP or static) on a local subnet which is assigned to the VPN network, and then configuring OpenVPN to point to that IP address.

For example, let's say you want to connect to a server called dvpserver.com, which has an IP address of 10.8.0/16 (ie, the 10.0/24 subnet). Your local network is configured with 192.168. So let's say you need a subnet of 10.1/16. You would set this in /etc/hosts:
1 dvpserver.com .and then set up OpenVPN to listen on all interfaces at 10.0/16 (this is the default setting), so OpenVPN will know what interface it should be connecting through:
#!/bin/bash. Open -s /usr/sbin/openvpn /usr/local/etc/openvpn/server.conf There are many other ways to configure OpenVPN, of course, but there is no one "right way" -- it's really just a matter of what works best for your situation.

How to setup VPN on Ubuntu terminal?

I have a server that has been working fine for a while and now it stops.

It's from OpenVPN (caliumpd).

The problem is that I'm not sure what might be the reason. I'm trying to access the server with another user using PuTTY but I get: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond".

There are no messages saying something has gone wrong. And all the other users, even root, can access the server without a problem. It's just this user I'm trying to access it.

Here is the result of the output of ifconfig from the server: eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx. inet addr:10.2.9.50 Bcast:10.255 Mask:255.0
