How to connect manually in console (without network-manager) in ubuntu 14.04?

[zerosum 0]

I'm unable to add the airvpn openvpn config scripts in ubuntu 14.04. This seems to be a bug in network-manager. So, I'm unable to use airvpn unfortunately.

 

Could anyone please advice on how to use openvpn through the terminal or command line.

 

Help is very much appreciated.

hi.

 

I'am having the same issue.

 

One way to overcome this is to use the openvpn client from the command line:

 

openvpn

 

 

:~$ sudo openvpn myfile.opvn 

 

 

but for this to work, i had to change the path to cert and key files like this:

 

ca "/absolute/path/to/ca.crt"
cert "/absolute/path/to/user.crt"
key "/absolute/path/to/user.key"
tls-auth "/absolute/path/to/ta.key" 1

tls-auth "/absolute/path/to/ta.key" 1

This doesn't work for me.  the script just sits there and hangs. Doesn't complete the connection. Yes I use the absolute path

 

I need to know how to configure OpenVPN without using a script. Other VPN services are able to do it. I tried to configure it manually according to the configuration in the script but it does not work.

It just sits there.

Hello!

@WcoRaaky

 

According to the logs the connection is perfectly successful. OpenVPN is not "sitting there", it just does not have anything else to output in the terminal at the moment. It is running just fine.

 

Kind regards

Hello!

 

After several tests we don't detect the bug reported in the forum in network-manager. Anyway, it is possible that we have been unable to reproduce it but the bug really exists. In any case please run OpenVPN directly.

 

What we detect, and this not good at all for security, is that network-manager runs OpenVPN so that no server certificate verification is required from your OpenVPN. We underline that this is bad for security reasons and we are investigating. This is another good reason ((the other reason is that network-manager does not pass explicit-exit-notify to OpenVPN) to run OpenVPN directly, as long as we do not release the client for Linux.

 

If you wish further investigations, after you import a .ovpn file in network-manager with OpenVPN plugin, please send us all the screenshots of its various configuration (one per each tab), they may give us important clues. No keys or certificates need to be imported one by one: if our instructions are followed exactly network-manager will do all the job automatically: ta.key, user.crt, user.key and ca.crt will be all read automatically by network-manager and their names displayed correctly in the relevant fields.

 

Kind regards

Hi,

 

  My apologies. By running from the command promt it does indeed work but it bypasses the network manager completely so you don't see the lock. If this is deemed safe then I would have no issues using this method from this point on.

Hi,

 

The broken import feature of an openvpn config file in ubuntu 14.04 is a high priority confirmed bug in launchpad: "Import saved VPN connection has been Recently Broken" (ubuntu / debian)

There's still no fix.

      I had the same problem using the network manager so I tried running from the command line and I kept getting an error. It finally occurred to me to try and download the config with out separating the Key's and Cet's, downloaded  the config as one file and it worked perfectly from the command line. I confirmed I had successfully established a connection by going to the Air Vpn site and checking the status at the bottom of the screen telling you whether your connected and to what server. No need to deal with changing the absolute paths or anything else. At the command line with sudo I just type "openvpn --config /home/dir/air.ovpn" (/dir being the directory where you stored your ovpn file) thats all anyone running Ubuntu 14.04 needs to do, at least until the network manager issue is resolved.
