ANSWERED DNS Problem? Can only connect to airvpn.org

Recommended Posts

Hi there,

 

Just installed AirVPN. I can connect to airvpn.org without any issues, but not to any other site. I have tried both with UDP and TCP. I'm using Bodhi Linux.

 

If I ping 10.4.0.1 everything seems to be fine:

Same if I ping 8.8.8.8:

traceroute google.com doesn't produce any results, it just hangs in there forever.

 

Thanks!

Hello,

 

yes, it seems a DNS issue. If you don't have resolvconf or openresolv packages installed, please edit your /etc/resolv.host file (as root)

 

and add the line:

 

nameserver 10.4.0.1

 

Then try again, feel free to update the thread.

 

Kind regards

Hi again,

 

Thanks for the reply. I do have resolvconf. I edited resolv.conf to add the line nameserver 10.4.0.1 and now everything works great...but I did see a warning on the file to not edit by hand as it will be overwritten. Anything else I need to change?

 

Thanks

Hello,

 

since you have resolvconf (sorry, the previous message was incomplete...) a more elegant solution is available.

 

Add to your .ovpn configuration files (to all of them) the following lines:

 

 

script-security 2
up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf

 

so that OpenVPN will accept the DNS push from our servers, and at the disconnection will restore the previous nameserver(s).

 

Make sure that "update-resolv-conf" script path is correct in your box.

 

up & down OpenVPN directives are used to tell OpenVPN to execute a script. "script-security 2" sets OpenVPN security level to 2, which means to allow calling of built-in executables and user-defined scripts.

 

Kind regards
