bringing up interface eth0 rtnetlink
Hi all,

OS: fedora release 10

when i try to restart network service, ending up with following errors. There are two interfaces eth0 and eth1
Code:
bringing up interface eth0 rtnetlink answers file exists
error adding <IP Address here> to eth0

bringing up interface eth0 rtnetlink answers invalid argument

below are ifcfg-eth0 and eth1 files under /etc/sysconfig/network-scripts/ directory

Code:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
BROADCAST=19.16.12.255
HWADDR=<MAC ADDRESS HERE>
IPADDR=19.16.12.125
IPV6_AUTOCONF=yes
NETMASK=255.255.255.0
NETWORK=19.16.12.0
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
NM_CONTROLLED=yes

# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
HWADDR=<MAC ADDRESS HERE>
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
NETMASK=255.255.255.0
IPADDR=<IP ADDRESS HERE>
GATEWAY=<GATEWAY HERE>
NM_CONTROLLED=yes
PEERDNS=No
DNS1=127.0.0.1
DNS2=<DNS IP HERE>


# service network status
Configured devices:
lo eth0 eth1
Currently active devices:
lo eth0 eth1


# service NetworkManager status
NetworkManager (pid  4236) is running...

There is another similar server, and ifcfg-eth0 and ifcfg-eth1 are similar(ofcourse different IP etc).
The other server is working fine.

difference is

Code:
on WORKING server

# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
IP ADDRESS HERE *               255.255.255.0   U     1      0        0 eth1
19.16.12.1      *               255.255.255.0   U     1      0        0 eth0
default         GATEWAY HERE    0.0.0.0         UG    0      0        0 eth1


on NON-WORKING server
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
IP ADDRESS HERE  *               255.255.255.0   U     1      0        0 eth1
19.16.12.0      *               255.255.255.0   U     1      0        0 eth0
link-local      *               255.255.0.0   U     1002      0        0 eth0
link-local      *               255.255.0.0   U     1003      0        0 eth1
default         GATEWAY HERE    0.0.0.0         UG    0      0        0 eth1

and WORKING server is able to resolve IP but NON-WORKING server is not able resolve IP and ending up with an error when it try to use nslookup command to resolve some other server

Code:
on WORKING server
# more /etc/resolv.conf
# Generated by NetworkManager
nameserver 127.0.0.1
nameserver <DNS IP HERE>

on NON-WORKING server
# more /etc/resolv.conf
# Generated by NetworkManager
nameserver 127.0.0.1
nameserver <SAME DNS IP HERE AS ABOVE FOR WORKING SERVER>

Please help to solve this issue.
Thanks in advance!

aoe-interfaces

aoe-interfaces(8)					      System Manager's Manual						 aoe-interfaces(8)

NAME

       aoe-interfaces - restrict aoe driver to specified network interfaces

SYNOPSIS

       aoe-interfaces [dev1] [dev2 ...]
       aoe-interfaces -c

DESCRIPTION

       The  aoe-interfaces command tells the aoe driver to ignore ATA over Ethernet (AoE) traffic on all but the specified network interfaces.	It
       is analogous to the aoe_iflist module load option.

       If neither the aoe_iflist module load option nor the aoe-interfaces command are used, the aoe driver will use any network interface for AoE
       traffic.   Using  aoe-interfaces  to limit AoE to only trusted networks prevents the case where a rogue AoE target appears on a public net-
       work, diverting data from the legitimate AoE target.  Such an imposter target effectively corrupts the data on the legitimate target.

       If the aoe driver is a module, then calling aoe-interfaces without arguments will display the current interfaces list.  If it  hasn't  been
       set then the output will be blank.

       It's good to run the aoe-discover command after setting the AoE interfaces list.

OPTIONS

       -c     The -c flag will clear the interface access list, permitting any interface to be used.

EXAMPLE

       In  this  example, the root user on a host named nai loads the aoe module with only eth0 allowable for AoE traffic.  After remembering that
       shelf 7 is on eth3, this sysadmin uses aoe-interfaces to add eth3 to the list of allowable network interfaces and then  calls  aoe-discover
       to ask the aoe driver to look for new AoE devices.

	      nai:~# modprobe aoe aoe_iflist="eth0"
	      nai:~# aoe-stat
		 e10.9		  eth0		    up
	      nai:~# aoe-interfaces eth0 eth3
	      nai:~# aoe-discover
	      nai:~# aoe-stat
		  e7.0		  eth3		    up
		  e7.1		  eth3		    up
		  e7.2		  eth3		    up
		  e7.3		  eth3		    up
		  e7.4		  eth3		    up
		  e7.5		  eth3		    up
		  e7.6		  eth3		    up
		  e7.7		  eth3		    up
		  e7.8		  eth3		    up
		  e7.9		  eth3		    up
		 e10.9		  eth0		    up
	      nai:~# aoe-interfaces
	      eth0 eth3
