Bring AirVPN Suite RC1 up on boot -- rc.local issue

Just started working on setting up vpn on a clean server using the new Airvpn Suite.  Nice work.  Seems like a more robust architecture that doesn't need the manual System-D fixes that using Hummingbird did.

Everything seems to be working as advertised when using goldcrest from a terminal prompt but does not work as expected via rc.local using this invocation:

goldcrest --air-connect --air-country canada --air-user <myairvpnusername> --air-password <myairvpnpassword>

Curiously, when I execute /etc/rc.local from the prompt, it works, but when rc.local is invoked on boot it fails to allow my user login (see post-boot journal grepped for bluetit below). 

Since my use case is to have vpn come up when the host boots and stay on permanently from then on, I am kinda stuck.   Any help appreciated.

Or maybe there is an easier way that I am missing?

Hello!

An easier way will be available soon, in the next version, which will support a specific option to have Bluetit connect during the bootstrap (you will need bluetit.rc properly configured with your AirVPN credentials).

As a first attempt, can you please change your account password into one which only contains ASCII characters in [a-z} U [A-Z}  U [0-9]?  We ask you to do that because the only difference we can currently spot is that in one case rc.local is launched by init, while in the other one it is launched by a shell which might have a different character set. By using only ASCII characters such a problem would be solved.

We are looking forward to hearing from you.

Kind regards

Thought about that and wondered why the password was not interpreted as a string literal.  Tried escaping the special character that is part of my password and also saving it double-quoted in a variable and expanding in the invocation, but that didn't work either.

I will let you know whether simplifying the password works.

Thanks,

For what it is worth, here is the output of the command: systemctl status rc-local.service:

I keep fiddling with this when I have a minute.   Tried adding an ExecStartPost directive to the bluetit service unit file to launch goldcrest command - i.e.,
  

/etc/systemd/system/bluetit.service:

osmc@osmc:/etc/systemd/system$ cat bluetit.service 
[Unit]
Description=AirVPN Bluetit Daemon
Wants=network-online.service
After=network-online.service

[Service]
Type=forking
PIDFile=/etc/airvpn/bluetit.lock
ExecStart=/sbin/bluetit
ExecStartPost=-/usr/local/bin/goldcrest --air-connect --air-country canada --air-user airvpnclient --air-password ****** & #<= PW OBSCURED
ExecStop=/bin/kill -- $MAINPID
TimeoutStopSec=20
KillSignal=SIGTERM
KillMode=process

[Install]
WantedBy=multi-user.target

This failed, as we can see from the status output:
  
osmc@osmc:/etc/systemd/system$ systemctl status bluetit

But interestingly, I did briefly get logged in before something threw a SIGTERM as we see from grepping goldcrest in the journalctl output.  Haven't gone through it closely, but there seems to be some difficulty with firewalling and DNS redirection...:

Hello!

That's expected, as systemd does not support daemons which fork (Bluetit performs a double fork). See here:
https://www.freedesktop.org/software/systemd/man/systemd.service.html

Look at "Options" for "Type=":
 
Quote

If set to forking, it is expected that the process configured with ExecStart= will call fork() as part of its start-up. The parent process is expected to exit when start-up is complete and all communication channels are set up. The child continues to run as the main service process, and the service manager will consider the unit started when the parent process exits. This is the behavior of traditional UNIX services.


You can then see why systemd sends SIGTERM when it meets a real daemon.

That's obviously obscene filthy crap, but makes Windows-ish and other miserable wannabe programmers happy, because allows them to run at system bootstrap, as "units", even processes which are not real daemons, which do not respect UNIX policy. Nothing to be surprised of with systemd anyway, you can't expect much from a repellent, non POSIX compliant crouch.

For your specific use case, you can consider to run Hummingbird, as runnning Goldcrest+Blueiti in that way does not make much sense, or you can wait for Bluetit release which (it's official now) will include options to connect at bootstrap.

Kind regards

Thanks.  Figured that Hummingbird was the way to go for now.  Yep -- not a fan of the Borg/Systemd myself.  As you say -- philosopically non-unix.

So long, and thanks for all the fish.
