Hi Steve,<div>Those static addresses are on the boxes right? I didn't see a mention of any router, are those layer 3 switches?</div><div>Thanks,</div><div>Michael<span></span><br><br>On Tuesday, April 10, 2012, Steve Johnson wrote:<br>

<br>
I am running 3 linux boxes all on the same network, running static 10<br>
net addresses, each on their own IP address.. A strange thing has<br>
started happening about a month ago, if I reboot the box when the<br>
system comes up at the point when it tries to bring up the eth0<br>
interface I get an error "IP Address in use by another host" and then<br>
the interface does not come up. Loggin in from the console as root<br>
and running ifup eth0 gives me the same error. The only way I can get<br>
the interface to come up is to physically unplug the ethernet, then<br>
run ifup eth0, that brings up the eth0 correctly, and then plug the<br>
ethernet cable back in.. Then it runs fine until another reboot (Or if<br>
I ifdown eth0 I will have the same problem)..<br>
<br>
I rebooted the switch last night, incase it was a switch issue and<br>
that did not clear it up. My switch guys assure me that nothing has<br>
changed on the switch. I have verified that there are not any rogue<br>
machines on the switch trying to steal my IP addresses.. So I am at a<br>
loss as to what could be causing this.<br>
<br>
It is happening on 3 Linux boxes, all three are on different hardware<br>
(same vendor, but different models) and all 3 are on different<br>
versions of linux<br>
<br>
Box 1 - RedHat Enterprise Linux 3<br>
Box 2 - RedHat Enterprise Linux 4 (Nahant update 5)<br>
Box 3 - RedHat Enterprise Linux 5.8 (Tikanga)<br>
<br>
The RHEL3 box was end of lifed a while back, so I know there have not<br>
been any patches in the time that this started failing.<br>
<br>
Here's my eth0 configs for each box, incase it helps.<br>
<br>
Box 1 :<br>
<br>
# Intel Corp.|82557/8/9 [Ethernet Pro 100]<br>
DEVICE=eth0<br>
BOOTPROTO=static<br>
BROADCAST=10.254.1.255<br>
HWADDR=00:02:B3:CF:16:DE<br>
IPADDR=10.254.1.58<br>
NETMASK=255.255.255.0<br>
NETWORK=10.254.1.0<br>
ONBOOT=yes<br>
TYPE=Ethernet<br>
<br>
Box 2 :<br>
<br>
DEVICE=eth0<br>
TYPE=Ethernet<br>
ONBOOT=yes<br>
BOOTPROTO=static<br>
HWADDR=00:18:8B:F7:1F:63<br>
NETWORK=10.254.1.0<br>
GATEWAY=10.254.1.1<br>
NETMASK=255.255.255.0<br>
IPADDR=10.254.1.60<br>
BROADCAST=10.254.1.255<br>
<br>
Box 3 :<br>
<br>
<br>
# Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet<br>
DEVICE=eth0<br>
BOOTPROTO=static<br>
BROADCAST=10.254.1.255<br>
HWADDR=00:19:B9:DD:CA:45<br>
IPADDR=10.254.1.46<br>
IPV6ADDR=<br>
IPV6PREFIX=<br>
NETMASK=255.255.255.0<br>
NETWORK=10.254.1.0<br>
ONBOOT=yes<br>
<br>
<br>
Ay ideas, or clues would be greatly appreciated.. I've been trying to<br>
trouble shoot this for over a month now with now luck.<br>
