I download OpenVPN Server on Debian, extract this file /etc/openvpn/client.tar.gz and that includes the following files:

  • client.crt
  • client.csr
  • client.key
  • ca.crt
  • client.conf or client.ovpn for windows client

I then copy all files to this path:

C:\Program Files\OpenVPN\config

I make edits to client.ovpn for some paths like:

ca /etc/openvpn/km31512-05.hostingaura.com-keys/ca.crt
cert /etc/openvpn/km31512-05.hostingaura.com-keyss/client.crt
key /etc/openvpn/km31512-05.hostingaura.com-keys/client.key**

change to this path for windows clients:

ca F:\\Program\ Files\\OpenVPN\\config\\ca.crt
cert F:\\Program\ Files\\OpenVPN\\config\\client.crt
key F:\\Program\ Files\\OpenVPN\\config\\client.key

and then run OpenVPN GUI and click for connect. This is log connect:

But OpenVPN GUI Status is yellow! not green? What is the problem? Here is my configure file:

export OPENVPN_SERVER="vpn.km31512-05.hostingaura.com"
export OPENVPN_CLIENTS="client"
export OPENVPN_IPRANGE="10.23.213"
export OPENVPN_LOCALDOMAIN="km31512-05.hostingaura.com"

Here is my OpenVPN server log:

I cannot ping from the Windows Client to 10.23.213.0.

How come my Windows client cannot connect to the OpenVPN server?

    Did you run make && make install after you extracted the files on the Debian box? After that you have to start the VPN daemon. Then you can connect from windows. — Don2007

    I used this tutorial. I ran apt-get install openvpn openssl liblzo1 — mohsen

    I'll try it on Ubuntu and FreeBSD. I don't have debian. — Don2007

    My friends tell me if the server is on the internet, then you can't connect from client to server! alright?? — mohsen

One of the entries in your OpenVPN log file says:

OpenVPN static key file /var/log/daemon.log:Feb 27 11:52:20 km31512-05 ovpn-server[28648]: Cannot open file key file '/etc/openvpn/keys/ta.key': No such file or directory (errno=2)

The file that contains your encryption key is missing. You need to run the following:

openvpn --genkey --secret ta.key

If you haven't run that command already, make sure to do that as it should solve your problem.

    I set up OpenVPN on Ubuntu without encryption or authentication just to see if I could get it to connect. I couldn't connect to it from XP so I installed it on FreeBSD and I was able to connect. However, after the "Initialization Sequence Completed" message, I couldn't do anything else with it. Am I supposed to be able to run commands the way I can with SSH or FTP? — Don2007
