Hi!

 

I'm using Ubuntu Linux, when connecting via Network Manager GUI everything works ok.

 

With airvpn_linux I'm unable to connect, here is the corresponding log, the relevant entry is "DNS checking failed"

In Settings > Advanced, disable Check if tunnel use AirVPN DNS. Then connect and check your DNS via ipleak.net.

Hi,

 

 

problem partially solved: connecting ok, but my DNS address is leaking! Any ideas?

 

BTW: this error does not occur with Ubuntu 14.10, even Network Manager having the same version.

 

Thanks!

Hello!

 

There are no DNS leaks on Linux. Even if your system queries different DNS servers, DNS queries are anyway tunneled. A DNS leak is when a DNS query is sent unencrypted outside the tunnel and this is not your case.

 

A possible explanation is that your system does not properly change nameservers because resolvconf package is not installed (but it should be pre-installed in any Ubuntu version). In this case, in "AirVPN" -> "Preferences" -> "Advanced" try to select "Renaming" in the "DNS Switch Mode" combo box.

 

If the problem persists please send us the content of your /etc/resolv.conf file while the system is connected to some VPN server.

 

Kind regards

Hello!

 

DNS was leaking, as was shown by ipleak.net, because -
 - the dhcp-option DNS 10.4.0.1 wasn't working - this was my problem description, so I couldn't connect at all because  this is checked by the client
 - after unchecking "Advanced -> Check if tunnel use AirVPN DNS" as suggested I could connect, but using my  ISP DNS.

Now, according to your suggestion,
 - I rechecked  "Advanced -> Check if tunnel use AirVPN DNS"
 - I set the DNS Switch mode to "Renaming"

and it works!

 

resolconf is/was installed.

In my last post I wrote about the Network Manager versions.
This was wrong, i wanted to write that OpenVPN has the same version, but not SSH and SSL


Ubuntu 14.10
OpenVPN - Version: OpenVPN 2.3.2 (/usr/sbin/openvpn)
SSH - Version: OpenSSH_6.6.1p1 Ubuntu-8, OpenSSL 1.0.1f 6 Jan 2014 (/usr/bin/ssh)
SSL - Version: stunnel 5.02 (/usr/bin/stunnel4)

Ubuntu 15.04
OpenVPN - Version: OpenVPN 2.3.2 (/usr/sbin/openvpn)
SSH - Version: OpenSSH_6.7p1 Ubuntu-3, OpenSSL 1.0.1f 6 Jan 2014 (/usr/bin/ssh)
SSL - Version: stunnel 5.06 (/usr/bin/stunnel4)

I'm not an expert, but I assume this has something to do with the problem.

 

Problem solved!

 

Thanks! I'm happy...

Hello!

 

We're very glad to know it! Additionally, no reasons to worry even for the previous state, because you had no DNS leaks. Even the queries to your ISP DNS were tunneled.

 

Kind regards
