[ale] IP Address reconfigruation in Cent OS 5 (RHEL 5.0)

[Paul Borghese]

Hi Everyone,

 

I have a crazy problem with a Cent OS 5 (RHEL 5.0) server.  I am trying to
statically configure my ip address, but the server will not allow it.  I
have edited the file /etc/sysconfig/network-scripts/ifcfg-eth0 to read the
following:

 

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=none

HWADDR=00:00:6c:3c:e5:f6

NETMASK=255.255.255.0

IPADDR=172.16.1.44

GATEWAY=172.16.1.1

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

 

 

Everything works perfect. I am able to stop and restart the network process
(/etc/rc.d/init.d/network restart) without error.  I can also manually bring
the interface up/down using ifup eth0 and ifdown eth0 without issue.  In
both cases the IP address is statically configured just as desired.

 

But here is the problem.  When I reboot the server, the file ifcfg-eth0 is
automatically changed to a configuration that points to a DHCP server.  So
after a reboot, my box is using a DHCP server to obtain addressing.  The
original file is saved as ifcfg-eth0.bak.

 

As a stop-gap measure, I could use an ifconfig statement in rc.local to
reset the IP address to the correct value.  But I would really like to find
out what is the problem and the philosophy for the configuration change.

 

I think it might have something to do with virtualization.  When I installed
the system, I selected to install the virtualization packages thinking it
would be something fun to experiment.  Later I uninstalled the
virtualization packages as I needed all available memory for a program I
need to run.

 

Once I get a free minute, I plan to read through the rc scripts to see if I
can find anything, but any suggestions would be greatly appreciated.

 

Thanks!
