Donning flame retardant cloak, I have a question for the network experienced...

After doing a non-fedora install of a like OS (but more community centric

, I find the network stack falls over if a user login on the console logs out!

anyone ever seen seen such a weirdness?

If you're talking of a GUI login on the console (e.g. KDE, Gnome, etc.)
AND the user runs the NetworkManager applet, of course it'll go away as
the user who set up the network is no longer at the machine. NM will
shut the network down until the (or another) user logs in again at the
console.

Unless NetworkManager is told to allow all users to use the network
profile (i.e., make it a system-wide profile).

Still wouldn't function unless someone's logged in. Personally, I never
use NM except on a laptop that's going to roam. I use the old, crusty
network scripts for machines that stay put.

Nope. On my F17 system, the wifi is managed by NM and it's available
whether someone's logged in or not. Run the NM setup GUI and check
"available to all users" at the bottom.

This is true even in F16. I have a desktop system with NM managing the
network. The system goes online as soon as it boots, without any users logging
in. I can ping it, I can login via ssh, I can read files served by httpd, and
all that... ;-) The only thing needed is the proper initial configuration of
NM.

HTH, :-)

Rick, if that were the case then I wouldn't be able to ssh into my
eeepc from my desktop when no one is otherwise logged into the eeepc.
But I CAN do that...

It's not clear if you are using NetworkManager or /etc/sysconfig/network-scripts
from your post.
My first instinct would be to look for a system log.
Is there a /var/log/messages file?
Does it show the network coming up when the system boots?
Does it show the network coming up when the console user logs in?
Is the console user automatically logged in when the system boots?
Does it show the network going down when the console user logs out?

Does this other OS support multitasking? *
What is the pid of the console user? *Is the console user the parent for the networking tasks?
I could imagine, in a stripped down Linux-like OS,*
rather than have /etc/rc.d/* start things up at boot,rather than have systemd start things,one might be sneaky (I'm trying to be kind),and start the system in single user mode,
have the console user automatically logged in,and things might be started by the console user.*

Possible. As others have stated, NM apparently will work if you set a
global profile and I suppose I have that enabled on the one machine
(laptop) I have NM enabled on since I, too, can ssh to it even if I've
not logged into its console. That being said, for machines that "stay
put" (servers and the like) I tend to use the old-school scripts.

Hmmm, it seems you can have multiple "global" profiles. How does it
decide which one to use by default if you have more than one? Has anyone
found official docs on NM? I haven't but I haven't looked recently.

I've only recently used NM in a more successful env; thx for this clue!!!
