Hi, 


Just configured Hummingbird on Ubuntu. Is there a way to make it run like a daemon or configure the connection so it connects automatically after reboots? Thank-you!

I have a problem with hummingbird on Fedora33, again.

I have got a power down (desktop) while humminbirg connection was on. Now I have no way to restore any connection.

--recover-network returns 
 

Hummingbird - AirVPN OpenVPN 3 Client 1.1.0 - 23 June 2020 

It seems this program has properly exited in its last run and
it has already restored network settings on exit.

ERROR: Backup copy of resolv.conf not found.
ERROR: Backup copy of network filter not found.

Also, I do not see any lock file in etc/airvpn (this is correct, though because my internet connection without VPN is active and working).

So basically I have no way to use hummingbird, any longer.

Excellent, thank you, bug detected, it will be fixed! ✌️

You should be able to start Hummingbird. If not, please read on.

You will need to delete some files manually. If deletion is necessary, before you delete please let us know the directory content:
 
ls -l /etc/airvpn

Finally:
 
sudo rm etc/airvpn/hummigbird.lock /etc/airvpn/resolv.conf.airvpnbackup /etc/airvpn/systemdns.airvpnbackup

Then start Hummingbird and check whether everything is fine again.

We are looking forward to hearing from you.

Kind regards

ls -l /etc/airvpn


 

This is the command output:

Hello!

You can now do that with Bluetit. Configuring Bluetit to connect during system bootstrap is a straightforward, very simple procedure, Furthermore, you will run a real daemon, and not a user process, therefore you have a higher security level. Bluetit can start and connect during bootstrap of both systemd and SysV-style init based systems.

I noticed some new lines in log - the connection was not disturbed, ipleak.net confirms no leaks - just curious what that is about

I'm noticing a similar issue to Maggie144, using Hummingbird with Eddie on macOS. In my case the connection is indeed disturbed - it happened while I was on a video call, the call would freeze for a couple seconds and then hundreds of "no buffer space available" messages would appear. Then it happened again just once today after I opened a torrent app. I'm attaching the last 1000 lines of the Eddie log in case that helps.

Hello!

For the error description:
https://developer.apple.com/forums/thread/42334

Of course, knowing what it means does not tell us why the kernel runs out of memory while OVPN 3 is over UDP and why only in macOS. We will keep an eye on it. How frequently do you have this problem?

Kind regards
 

Very interesting, thank you for the explainer. I'd say it happens every half-hour or so when under constant load - not a dealbreaker for personal use really, but it can get a bit annoying.
