[Resolved] OpenVPN First-Startup

Post by HalfEatenPie » Tue May 08, 2012 7:43 am

Hey there! Hopefully I put everything down so it's easy to understand! Also, thanks for all your help!

The Setting
I followed the Installation How-To using the Without RPM settings. yum install openVPN would say "No package openvpn available." I somehow magically stumbled on through the How-To all the way to "Starting up the VPN and testing for initial connectivity". I did hit several speed bumps (aka I might have missed some stuff previously) but most of them I was able to solve using Google.

The Goal
To get a working VPN with my laptop (I'm failing)

The Problem
This following code shows up with I run the code: openvpn server.conf

Code: Select all

My Background
I know HTML, CSS, C++, PHP, all that jazz but SSH is where I just don't know.

Thanks for all your help! I've been working on this all night and I just can't seem to get it right.

Edit: For those of you guys who got here late, I just did a clean install. I've moved on to another problem located here: topic10537.html for those of you interested (if not that's cool too, just keeping the line flowing).

Running modinfo tun provides:

[root@chocolate sample-config-files]# modinfo tun
ERROR: modinfo: could not find module tun
Additional Note: I have already enabled TUN/TAP from the SolusVM control panel.

As for the EPEL Repo I got the RPM (I'll be testing that out later when I have more time) but is it possible to integrate the EPEL list with YUM? (I understand this is un-related to the OpenVPN problem so feel free to not answer it)

Thanks for all your help!


Edit: forgot to mention that I ran the command as root

the rpm you search is named epel-release-6-5.noarch.rpm

after you install it yum will query epel repo too...

tun module is missing (?)

Would you think the problem is because I could possibly be missing some important libraries/additional software OpenVPN could need?

Also, I've been looking for the EPEL .rpm file but I haven't been able to locate one. I usually end up at the repository where individual files available to the .rpm are hosted.

Also, Fedoraproject doesn't have the following file on their server (or atleast it returns a 404).

http://download.fedoraproject.org/pub/e ... noarch.rpm
The above link is bad (to my understanding atleast).

Could you please clarify by what you mean "tun module is missing (?)"

Thanks again for all your help,

Don

Hey maikcat,

I can't seem to send PMs. On another note if I want to re-do my installation is it ok if I just delete the OpenVPN folder I used? (e.g. I can currently run commands "openvpn ___" but if I delete the folder I installed OpenVPN on and tried another clean install would that be ok?).

Under the installation HowTo without the RPM. Therefore I installed it using the tar.

hi

for your "script-security 2" put this into your server.conf file
and for certificate missing error you have to give the complete path like
ca /etc/openvpn/keys/ca.cert
same like for server.key check if it is under /etc/openvpn or under /etc/openvpn/keys

Please update if it is helpful for you
