NetworkManager-0.7.0-0.9.1.svn3549.fc9.i386

Besides the one for "lo" there are only config files for eth0 and eth1.

/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:13:8F:D9:B8:9C
ONBOOT=yes
DHCP_HOSTNAME=nexus
TYPE=Ethernet
USERCTL=no
PEERDNS=no
IPV6INIT=no
NETWORKMANAGER=yes
NM_CONTROLLED=yes

/etc/sysconfig/network-scripts/ifcfg-eth1:
DEVICE=eth1
BOOTPROTO=none
HWADDR=00:50:04:49:E0:EC
IPADDR=192.168.1.1
NETMASK=255.255.255.0
ONBOOT=no
TYPE=Ethernet

This is what it says after the ifdown=>ifup:

NetworkManager Tool

State: connected

   Type:              Wired
   Driver:            forcedeth

   Wired Settings

(I've added "prepend domain-name-servers 195.50.140.178, 195.50.140.114;" 
to dhclient-eth0.conf so I get decent nameservers in resolv.conf)
