[SOLVED] Ubuntu NetworkManager and keepalive

[kafebob 0]

Hi there,

I'm using this service since 1 month ago and I'm very happy with the quality and the support on forums.

I hope the admin guy can help me with this.

Until now, I´m connecting through Ubuntu NetworkManager and everything works great, but, it seems like the connection is lost (usually in the nights when I'm sleeping ) and NetworkManager fails to reconnect again.

I tried to add the directive "keepalive 10 60" in air.ovpn and re-import again this file into NetworkManager, but it seems like the keepalive directive is not supported .

So, today I tried to run openvpn directly through console like this

"sudo openvpn air.ovpn"

And I get this output...

What I'm missing? Any suggestion to auto reconnect openvpn when the connection is lost.

@kafebob

Hello!

The logs look ok. Can you please make sure that you are not trying to double-connect your account (AUTH_FAILED...)?

Kind regards

Thanks for the answer,

I did the following steps with the same result :S . (With NetworkManager works perfect but with the reconnect issue)

1) I restarted my pc

2) I executed :

sudo service openvpn stop

* Stopping virtual private network daemon(s)... * No VPN is running.

3) In my vpn folder i executed "sudo openvpn air.vpn"

And I got this output

Hello!

The probable cause is that you are mixing OpenVPN usage. If you launch openvpn with "sudo openvpn ..." then you can't stop it by stopping the daemon (simply because there's no daemon managing the connection).

To see how to use OpenVPN as daemon and where to put the files in this case:

I don't know if you did something but now the connection works. :silly: .

Anyway, thanks for the quickly support.

Hello!

You might accuse us to be lazy, but we didn't do anything at all. We could not detect any problem... so it's great to know that the problem solved "by itself". Perhaps it was just a momentary issue on connections between your provider and ours.

Kind regards
