I use static IP on eth0, and both dynamic and static on wlan0, depending
on where I am. My eth0 configuration is in /etc/network/interfaces and
the rest was specified using nm-applet. Network Manager also manages
eth0 according to /e/n/i, so I can turn it on/off using nm-applet and it
shows when the cable's plugged in or out.
Here's /e/n/i:
----------------------------------------
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
#iface eth0 inet dhcp
iface eth0 inet static
address 123.123.123.22
netmask 255.255.255.0
network 123.123.123.0
broadcast 123.123.123.255
gateway 123.123.123.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 123.123.124.125 123.123.145.156
----------------------------------------
(I changed the addresses above to fictional ones. I also remember
reading on this list several times that nowadays you only need one or
two of netmask/network/broadcast/gateway to be specified, but I just
kept my old settings.)
The settings for wireless were entered in using nm-applet, so I'm not
sending any files.
You also need to tell Network Manager that it should take care of eth0
but according to the settings in /e/n/i. You do this by editing
/etc/NetworkManager/NetworkManager.conf:
--------------------------------------------
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=true
--------------------------------------------
