I have a fc2 box that when I set it with a static IP it will maintain the address for about a couple minutes then it will be reset with the DHCP assigned address.

Nothing I can find in my configuration files has anything set for DHCP. Even the GUI network app shows that it’s supposed to be a static address.

Any help is appreciated.


Configuration files below…



[root@advserver sysconfig]#cat network
NETWORKING=yes
HOSTNAME=advserver.pel.com

[root@advserver devices]# cat ifcfg-eth0
# Intel Corp.|82540EM Gigabit Ethernet Controller
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:C0:9F:17:0F:5A
ONBOOT=yes
TYPE=Ethernet
#DHCP_HOSTNAME=advserver.pel.com
DPADDR=192.168.254.203
NETMASK=255.255.255.0
USERCTL=no
PEERDNS=yes
GATEWAY=192.168.254.9
IPV6INIT=no

questions:

1. have you tried commenting changing the line D PADDR=192.168.254.203 to I PADDR=192.168.254.203 (or is that a typo)?
It may be that you have mangled your file in attempting to convert it from dhcp to static ip. it should look something like:

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
HWADDR=00:C0:9F:17:0F:5A
BROADCAST=192.168.254.255
NETWORK=192.168.254.0
IPADDR=192.254.1.203
NETMASK=255.255.255.0
USERCTL=no
PEERDNS=yes
GATEWAY=192.168.254.9
IPV6INIT=no

2. do you have a file named /etc/sysconfig/network-scripts/ifcfg-eth0.dhcp (if so, rename it to something else)?

after either of the above issue the following commands and post back here the results of:

service network restart
mii-tool
netstat -nr

Yes it was a typo is the output of the commands and the correct file. I can not do a service network restart because this is a production fileserver and my users would flog me

[root@advserver devices]# /sbin/mii-tool
eth0: negotiated 100baseTx-FD flow-control, link ok

[root@advserver devices]# netstat -nr

[root@advserver devices]# cat ifcfg-eth0
# Intel Corp.|82540EM Gigabit Ethernet Controller
DEVICE=eth0
BOOTPROTO=none
HWADDR=00:C0:9F:17:0F:5A
ONBOOT=yes

#DHCP_HOSTNAME=advserver.pel.com
IPADDR=192.168.254.203
NETMASK=255.255.255.0
USERCTL=no
PEERDNS=yes
GATEWAY=192.168.254.9
IPV6INIT=no

The only thing I might try would be to change
BOOTPROTO=none
to
BOOTPROTO=static

Haven't encountered the this type of problem before.

Have u tried setting ur ip manually using the ifconfig command and then check that if the ip gets reset after some time.

if i do a ps -aux | grep dhc i get this..

1551 ? S 0:20 /sbin/dhclient -1 -q -lf /var/lib/dhcp/dhclient-eth0.leases -pf /var/run/dhclient-eth0.pid -cf /etc/dhclient-eth0.conf eth0

is it possible that the dhcp client is running and just keeps resseting my ip because its not even looking at the ethernet config file...

Can i stop this process ? will it fix this? Why is this running and how can I make sure that if this is the sollution that the service doesn't ressurect after a reboot.

As root:
kill 1551

Now try the commands
ifdown eth0
ifup eth0

Check to see if dhclient starts again.

I vote with michaelk. Change BOOTPROTO to
"static" and let us know if dhclient still starts up
after the "ifdown ..." followed by the "if up ..."

That fixed me up. Killed dhclient static stayed and dhclient did not restart. I bounced my server over the weekend to make sure the process wouldn't ressurect on a reboot. Everything is perfect. Thanks!!
