Connecting to an OpenVPN from a CentOS5 server

Feek · 24 Feb 2019 at 23:36

This is an odd request and I'm struggling to find a guide.

I have OpenVPN running on a Pi and I need to connect to it from a CentOS5 server and only have certain ports forwarded from the outside world to the CentOS5 box (a small range of TCP/IP ports and a couple of UDP ports)

I've generated a .ovpn file on the Pi but I can't find any guide on doing this. There are plenty of how-tos to install and configure OpenVPN server on CentOS5 but not about running it as a client.

/edit - My big problem is installing OpenVPN on the CentOS5 box. All the guides seem to refer to a repo which no longer exists. I think if I can just get it installed, I can make it work. Help!

It's a long shot but can anyone help please?

I found this which looks as though it contains the package I want but I have no idea what to do with it. How can I install this?

Download the package to your server and run:

Code:

rpm -ivh path to rpm

Actually came back to say I've found that command

And it helps to have the correct 32bit rpm!

I'm getting there.

Code:

# rpm -ivh openvpn-2.3.14-1.el5.i386.rpm
warning: openvpn-2.3.14-1.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6
error: Failed dependencies:
    liblzo2.so.2 is needed by openvpn-2.3.14-1.el5.i386
    libpkcs11-helper.so.1 is needed by openvpn-2.3.14-1.el5.i386

Now I need to find these two dependencies *sigh*

Looking for the first of those, can anyone suggest what I should choose from here for 32 bit CentOS5?

I've got it working. Well, I've got it installed.

Just a quick note, CentOS 5 is end of life, you're no longer getting any updates, including security updates. You should upgrade to a supported version.

Yes, I’m fully aware of that. If the application would work on a newer version then that would be an option.

It doesn’t so therefore it isn’t. A newer version of the app is being rolled out and we will probably go to that on newer hardware later this year but for the moment, I have to work with what I’ve got.
