Bug Description
Have a laptop running 8.10. As a travelling device I use a 3G phone to 'network connect' through.
It does work - quite well when it works - but is ... temperamental to actually make work.
In that on the phone I need to "Connect" "Disconnect" "Connect" "Disconnect" cycle until NM finally recognises that the phone is there.
Sometimes it "just works" as soon as the phone is activated; other times it can be an exercise in patience for 10-20 minutes. :-(
The key lines I've found to watch for in syslog appear to be these as indicative of a failure:
Jan 21 10:53:19 geriatrix hal-dccm[13549]: CRITICAL: check_interface_cb: unable to listen on rndis port (990), server invalid
Jan 21 10:53:19 geriatrix hal-dccm[13549]: CRITICAL: check_interface_cb: unable to listen on legacy port (5679), server invalid
I've tried at various times:
killing the nm daemons; unloading the rndis kernel module; enabling/disabling networking. Unplug the phone etc. All to no avail. I can't find any one 'solution' that is reliable.
It's possible there is an override to tell NM (or whatever?) - hey ignore what you think is happening - do *this*. ???
See attached syslog extract showing a couple of fails followed by a final success.
