ANSWERED Relatively New To Linux and VPNs - Fedora 22: AirVPN Client Cannot Connect

Recommended Posts

Hello,

 

I am fairly new to Fedora 22 and Linux in general, having only been using said OS for about 3-4 weeks. I've been constantly using this VPN service on my other OS (Windows 10) with absolutely no issues. However, I'm having an incredibly hard time getting the client to work on this OS. Every time that I attempt to connect to a server, the client begins to connect, disconnects, and restarts. Any help would be greatly appreciated. A sample of the logs is below:

The VPN connection seems fine, here's the actual problem:

I 2015.08.13 07:40:59 - Checking DNS
W 2015.08.13 07:41:02 - Error: NameResolutionFailure

The AirVPN client "tries to resolve domain names that are resolved only by our DNS server, to ensure that system is correctly querying our DNS server."
This check fails for some reason. Multiple users have recently reported similar problems so there might be a problem on Air's end.

Here's a quick workaround:

Go into Preferences, Advanced, DNS.

  • uncheck the box "Check if the tunnel uses AirVPN DNS"
  • establish a VPN connection
  • to check DNS manually, run this in a terminal window: cat /etc/resolv.conf

The file /etc/resolv.conf lists all your system's DNS servers and should only contain one of Air's DNS (10.X.0.1).

You should also check that file to see if your default (non-Air) DNS servers are restored after disconnecting from AirVPN.

Also, just to check but you did install the package 'beesu' right? Air's client needs it to be able to work properly. You'd need to close Eddie, then open a terminal and type:

 

 

dnf install beesu

 

and hit enter. After the install you could fire up Eddie again and see what happens. But as was said, it could well just be an Air DNS issue. Just mentioning it in case, as it caused me a huge headache last year on F21 until I found out lol.

Thank you both very much for your responses.
Sheivoko: Your fix worked! I very much appreciate the fast response and effective solution!

Rainmakerraw: I have beesu installed! While disabling IPv6 and trying to fix this by reading other posts, I came accross many people with similar issues, but had I not done that, I would've been in the dark about the beesu install.

 

Both: Thank you very much for your help, time, and your politeness!
