[SOLVED] switching to networkmanager

Hi all!
I am trying to get Connman to work with VPN on the KDE build, but importing my openVPN conf file will always return an error (VPN disengaged). The same file was always working flawlessly with NetworkManager, but I can't get plasma-nm to even start after installing the package and the relative s6 service. Any help for properly configurating the service, please?

What happens when you run openvpn /path/to/client.conf as root? Do you have
Code: [Select]
log-append /var/log/openvpn/client.log
in your client.conf?

Can you post the output of
$ mount | grep devtmpfs
$ ls -la /dev/net/tun*

If 2) gives you nothing, try running these commands as root:
# mkdir -p /dev/net
# mknod /dev/net/tun c 10 200

After this, try running openvpn /path/to/your.conf and checking the log file.

thanks for your help :) the second line gave me nothing, but i followed your instructions and finally got the vpn working, both from command line and with connman. The problem is that connman keeps disconnecting randomly, i don't really understand why ::)

It is conning you!

If you do not like it, just switch to NM (disable connman and enable NM)

Ok, uninstalled connman and installed NM, but how can I get the service to automatically run at startup?

First, see what is in your current s6 default bundle and take note: s6-rc list default

Next we need to delete the bundle: s6-rc-bundle delete default
Now we add, also make sure you add in those previously listed in the first step.
s6-rc-bundle add default OTHER-ONES_LISTED NetworkManager
