[Bug 1690684] Re: samba panic

[Andreas Hasenack]

Ok, your eth0 network interface is controlled by network manager then.
This means that it only becomes available after you login on your Ubuntu
desktop, and that's why samba is failing: the network interface you told
it to use is not available when samba starts.

You have some options:
a) do not specify the interfaces line in /etc/samba/smb.conf. This is usually only needed when you have multiple interfaces and want to control where samba will listen. I'm not sure if samba will pick up eth0 once it becomes available, you should try it.

b) Specify the eth0 interface details in /etc/network/interfaces. See
the interfaces manpage with "man interfaces". Then it will be brought up
during boot, and will be ready for samba when it starts.

c) Workaround: configure samba to not start automatically. You would
then start it manually after you login on your desktop and the network
is available.

I suggest you try (a) first, unless you have multiple interfaces and
really need samba to only use eth0. Or if samba doesn't pick up your
eth0 network once it's up (after you login). If that doesn't work, then
you should really treat this machine like a server and go for (b). (c)
is a workaround.
