I have a fresh install of 13.10 and my networking works fine (cable model cloud router) via the standard network manager applet.
I'm trying to setup my box to a use static IP instead of dhcp and I'm trying to use your guide: https://help.ubuntu.com/13.10/serverguide/network-configuration.html#ip-addressing
Basically, the settings via the networking applet seem to be conflicting with what I see on the command line.
a) The ifconfig -a shows eth0 with the inet address assigned via dhcp.
ifconfig -a
eth0 Link encap:Ethernet HWaddr 44:87:fc:97:ed:24
inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::4687:fcff:fe97:ed24/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:61170 errors:0 dropped:0 overruns:0 frame:0

lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
.....
.....
b) However, the interfaces file does not have even eth0 defined.
cat /etc/network/interfaces
auto lo
iface lo inet loopback
c) I could not even do:
sudo ifdown eth0
ifdown: interface eth0 not configured
How is this possible or what am I basically missing ?
Will the steps in the link above for configuring a static IP work ?
Thanks,
