Luverly, just luverly I say.  NetworkManager has been there and destroyed 
the reference copy.  Here is the outline of how mine Just Works(TM)

Expunge NM and be done with it.

Here is the interfaces file from this machine, with some addresses 
hidden.
---------------------
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
#
# list of interfaces to ayto activate
auto lo eth0
# interface lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0
# interface eth0
iface eth0 inet static
address 192.168.xx.3
netmask 255.255.255.0
gateway 192.168.xx.1
------------------------
(the eth0 address in each machines interfaces file is of course that 
machines address.  All completely arbitrary, set by you on each machine 
on ypur local network.

/etc/resolv.conf is a real file, not a link, and contains one line:
nameserver (same ipv4 addr as gateway above, let the router sort dns 
query stuff)
-----------------
If not using dhcp for obtaining a local address (I've yet to figure out 
how to do local dns searches by names when dhcp obtained the address, 
probably my stupidity, but there it is) and are using an /etc/hosts file 
for local dns resolution, it should resemble this on every machine on 
your local network(add more machines as required, up to 254 IIRC):

gene@coyote:/opt/nitros9$ cat /etc/hosts
127.0.0.1 localhost
192.168.xx.1 router.coyote.den  router
192.168.xx.3 coyote.coyote.den  coyote
192.168.xx.4 shop.coyote.den    shop
192.168.xx.5 lathe.coyote.den   lathe
192.168.xx.6 lappy.coyote.den   lappy

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
--------------

All hostnames above were set once by (example for this machine)
$hostname coyote.coyote.den
etc etc for the other machines when they were installed.

And you just did me a favor John, my lappy could not login the last time 
I plugged it in, its line was "lappy.coyote,den".  Error now obvious.

I suspect it will Just Work the next time I power it up. If the battery 
isn't crowbared by now, its the OEM battery yet, and about 13 years 
old. :(

Perhaps not the way you were doing it, but "It works for me" :)
