17.10 network changes

[David]

Hmmm.  Want to tell what file that was?

I'm not at home at the moment.  I found by comparing 2 installs, and I
couldn't quite believe it when it fixed it.

>From a quick Google, I think is this file, located under /etc... and
/var....

10-globally-managed-devices.conf


https://askubuntu.com/questions/882806/ethernet-device-not-managed

I'll have another look when I get home.

Hi,

Two things to check:

1. What is the name of your network device?  I had an update change the
ethernet device name from eth0 to enp3s1 or some such nonsense that is
supposed to give consistent naming even if I add in additional adapters
into my laptop.  You can grep through dmesg to find out.  Or you can find
the name out when you ip addr .

Thanks for the reply.   Name is enp3s0 and has been that since 16.10.  And
that name is picked up by dhcp but I can’t get a static address assigned
like I could in 16.10



2. Is network maanger running?

Yes, and I’ve played with starting and stopping it as well as a lot of
other tricks.


You can force network maanger to use the interraces file.  The debian site
tells you how.
https://wiki.debian.org/NetworkManager


Will take a look at this.

3. Okay, I lied there is a third point.  Have a looked through your syslog
to find out what's happening?

Using dmesg I see that enp3s0 is shown as up and down many times during
startup...  so maybe it is a timing problem.  Will do some more looking at
syslog.  I WAS able to use ifconfig to assign the static address that is in
the interfaces file and that works as a temp fix so it indicates everything
is working except the use of the interfaces file.  But this problem is a
showstopper as far as I am concerned.

Good luck.  Thsee things are frustrating.  I had a similar problem getting
network manager to work.  The problem was a certain zero byte file was
missing.


Hmmm.  Want to tell what file that was?

problem.  Will keep looking.

I've seen a few people complaining about this, but it seems a rare
issue. There were some networking changes by the Ubuntu devels, so you
should perhaps search Launchpad for bug reports and add your details
there.

Kubuntu doesn't handle networking beyond providing the Plasma widgets
that display what's going on; that is all done at the systemd and
networkmanager level, by the core Ubuntu developers.
