Network Address Periodically Changes Without Warning


Hi there --

We have a Fedora Core 2 system that is configured with a static ip address. The system has been registered in our DNS domain with the appropriate hostname and address information.

Periodically, and without warning, the address suddenly changes to a different one. This occurs while the system is on, and does not occur during a reboot. The last reboot of the system occurred over a month ago.

I checked the /etc/sysconfig/network-scripts/ifcfg-eth0 file, and confirmed the IPADDR, NETMASK, and GATEWAY fields had the correct information. Also, the BOOTPROTO line had a value of static.

I checked the /var/log/messages file, and I discovered several instances of the following:

dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67.

Port 67 is the Bootstrap Protocol server.
Why is this occurring, and how can I correct it? Thanks.

Well from the messages log it appears that eth0 is requesting an address via DHCP. Even though the /etc/services file reports port 67 as the Bootstrap Protocol that is what DHCP uses as well.

Somehow DHCP is configured for that interface. I'm not familiar with Fedora so I'm sorry I can't provide more help.

Thanks.

I believe you can use 'ifconfig' to change the conf for that interface and take out dhcp and put the static settings. Or go under Admin -> Network. (Been awhile since ive even looked at core2.
