Hi, I've a netgear r7000 router, so on that router I can install dd-wrt and tomato firmware on both of that I can install entware, so I can install, actually I do that with both firmware, python3 and all dependencies.

So all works till the script don't try to install the start/stop script, I got this error

Traceback (most recent call last):
  File "/opt/bin/openpyn", line 11, in <module>
    load_entry_point('openpyn==2.6.0', 'console_scripts', 'openpyn')()
  File "/opt/lib/python3.6/site-packages/openpyn/openpyn.py", line 130, in main

  File "/subprocess.py", line 709, in __init__
  File "/subprocess.py", line 1344, in _execute_child
FileNotFoundError: [Errno 2] No such file or directory: 'systemctl': 'systemctl'

So I've 2 question

  1. I can use the -n option (I saw only asus merlin)? In that way I've to manually add a start/stop script to make it works, right?
  2. Is possible, in future, to make it works without the systemd service?

Many thanks for this works! I like it!

Thank you.
I have implemented ability to test if systemd is found or not. This should work for non systemd Linux system. (-d won't work obviously). Give it a go.

sudo python3 -m pip install --upgrade openpyn

Thank you, I'll try it, in some day I'll have my new R7800 so will make some new test to see if works!

Would be very beautiful use this piece of sw on router, then just need
a proper script to start it automatically -> easy
some rules for the firewall, like a kill switch -> easy
a cron to check the connection? -> is needed?

What do you think?

@Jorman add "check for DNS leaks" to your list :)

I never know the existence about it till yesterday. I saw voxels fw and after some search I saw this DNS leak! I don't know if there's a way to install this into ddwrt, I'll search when the router arrive!

Ok, I've the router but...
Installation ok, with python3 module, only one note, the command is
python3 -m pip install --upgrade openpyn

But in my case I don't need sudo, I'm root user, and on R7800 python3 don't symlink pip3 into pip, so I only had to symlink pip3 into pip

So installation was ok but when I try to save the credentials I got this:

Enter the password for NordVPN:
wget: not an http or ftp url: https://downloads.nordcdn.com/configs/archives/servers/ovpn.zip
Exception occurred while wgetting zip, is the internet working? is nordcdn.com blocked by your ISP or Country?, If so use Privoxy [https://github.com/jotyGill/openpyn-nordvpn/issues/109]

Internet is up and no block on ips. To me seems can't find wget or can't write on basepath?

root@DD-WRT:~# which wget
/usr/bin/wget
root@DD-WRT:~# ls /opt/bin/wget
/opt/bin/wget
root@DD-WRT:~# ll /opt/bin/wget
lrwxrwxrwx    1 root     root           8 Aug 25 14:50 /opt/bin/wget -> wget-ssl

I don't know what can be a best solution in this case.
Where I can find the credential file? so I can set it up by hand and maybe I can force the very 1st downlod of the zip configuration file.

Any idea @jotyGill @yuriw

Found the problem, wget used is not the one from opt but from busybox! For now I fixed but I've another problem on connecting phase, see the log:

Take note that maybe I've to install some command, I use Entware on ddwrt kong system.

Tell me if you need some other logs or some other tests
Please note that I had to install setuptools in order to install openpyn
python3 -m pip install --upgrade pip setuptools wheel

I've 2 questions for you @jotyGill

  1. When all will work, can I set up a cron in order to check if I'm connected to the best case and switch to the best one if not? For example I plan a cron every hours and with a command like openpyn it --p2p the script check if I'm already connected to the best server otherwise connect to the best one. I ask this because I don't know how it works, I never see it in action :D

  2. Do you have any plan to specify the client (ip or mac address) that can use the openvpn connection? Like the --allow arguments but for ip, ip range or mac address

I don't know if is important but on the router a openvpn server is configured and I added this to my firewall rules in order to navigate through internet when I use the connection to the server

WAN_IF="$(route -n | awk '/^0.0.0.0/{wif=$NF} END {print wif}')" 
iptables -t nat -I POSTROUTING -s 10.8.0.0/24 -o $WAN_IF -j MASQUERADE

Any idea?

For what it's worth - I ran this on Ubuntu WSL on windows (and it doesn't have systemd)
And it gave me a very nice and clean error:
System has not been booted with systemd as init system (PID 1). Can't operate.
without any failures
