Cant connect to any server, always restarting

[devidd55 0]

Hello,

 

I am using Eddie to connect to AirVPN but it is always failing. I am by no means an advanced techie to understand how to fix the problem, so if you could help me it would be much appreciated.

 

Here the logs of one failed attempt:

I am guessing the problem is at "RTNETLINK answers..."

If this help (sorry if it is completely unrelated) i have a Ralink Adapter RT3290 which is a nightmare in linux , with many users having auto-wake problems after shutdown, since there are no supported drivers specifically for it anymore, and by default rt2800pci is used (which works quite well, except for the auto-wake problem and the fact that i cant login to my university's eduroam wifi). So here are my 2 cents.

Hello,

 

https://airvpn.org/topic/20939-eddie-openvpn-24-rc2-issue-no-connection-could-be-made-because-the-target-machine-actively-refused-it/

 

Kind regards

Thank you!

 

It seems the problem was with Eddie. I would like to add here for the other users, that i am using Arch Linux. I had installed the airvpn-git from AUR and that is why it was not working. I am using airvpn-beta-bin now.

 

It fixed the problem above, but a new problem emerged: it started showing "DNS checking failed". A quick search sent me to this article https://airvpn.org/topic/13641-airvpn-linux-client-unable-to-connect-dns-checking-failed/ and after unchecking "Advanced -> Check if tunnel use AirVPN DNS" i could connect. I also switched to DNS Switch Mode to "Renaming", because i was getting DNS leaks when checking with https://ipleak.net/ too.

 

I want to ask the Staff, how come that i was getting DNS leaks, even though i am on Linux???

 

Last concern i have, partly because of the DNS leaks mentioned above, is if i should make other tweaks to ensure full functionality, or if i should just dump Eddie and connect via Network Manager. I dont know if the steps i took are enough to fix these "loopholes" in Eddie.

 

Thank you for the quick response and wish you well for the new year

Ok, it seems i was wrong. No matter which DNS Switch Mode i used, my IPv6 will leak on this site http://whatismyipaddress.com/

 

Another funny fact is, when i choose "Automatic" as DNS Switch Mode, my IPv6 won't leak only as according to ipv6leak.com/

When i choose "Renaming" my IPv6 won't leak only as according to https://www.iplocation.net/find-ip-address

 

This is making me even more confused..

Hello!

 

Just turn off IPv6. Support for it is planned for 2017 .

 

Staff has said there's no DNS leaks on Linux. If you use Network Lock, then that's definitely ensured.

 

Do check ipleak.net as well.

 

Welcome to AirVPN and happy new year !
