[Bug 1690684] Re: samba panic

Thanks for attaching these. I see a few potential issues:

a) Your /etc/samba/smb.conf has an invalid realm setting:
	realm = comco1.com <http://safco1.com/>
It should be just comco1.com and not have that url next to it

b) The reason you are getting panic seems to be because the smbd process cannot open sockets on the specified 192.168.0.4 IP:
        interfaces = 192.168.0.4/24 eth0

b.1) Is that network correctly setup on that box?
b.2) Have ou tried 192.168.0.0/24? That would tell samba to look for any local interfaces that are attached to that CIDR.

In fact, I can reproduce your panic action by setting "interfaces =" to
a list of networks and interfaces that do not exist on my test box.
