Re: NetworkManager dispatchers

I made a progress. I enabled debugging and I saw the NM was complaining about dual-stack:

I set the ipv6 method to ignore:

[connection]

type=gsm

[ipv4]
dns-search=

[ipv6]

and this is what I get on startup now:

but when I do con up, I still get nothing:
root/usr/local/etc/NetworkManager/system-connections# nmcli con up ppp
Error: Connection 'ppp' does not exist.



Any ideas what is going on?

I removed the connections and restarted NM and did what you suggested and here is what I get now:
nmcli con add type gsm con-name ppp ifname ttyUSB2 apn internet.com
Connection 'ppp' (94e24340-490b-4f96-91bb-c5511a2a5f50) successfully added.

root/usr/local/etc/NetworkManager/system-connections# nmcli con up ppp
Error: Connection activation failed: Active connection removed before it was initialized
root/usr/local/etc/NetworkManager/system-connections# nmcli con up ppp
Error: Connection activation failed: Active connection could not be attached to the device


I wonder what that means...hmmm


Thanks a lot for your help!

The interface part is likely your problem.  interface-name is the name
of the NetworkManager control port, which in your case would be ttyUSB2
(as reported by 'nmcli dev').  Data ports (like ppp0) are transient,
they come and go, so locking the connection profile to a specific
device needs to happen with the control interface name.

If you change that to ttyUSB2 or even just remove it entirely, what
happens?
