I have a urgent problem to solve today, but I'm lost. Please help.
I've cloned a Virtual Machine hosted on VM Ware ESXi 4.1
The OS is now Ubuntu Server 12.04 LTS, but at the time of cloning it was 10.04 LTS.
I fixed the MAC address manually inside /etc/udev/rules.d/70-persistent-net.rules
. It is a known problem on Ubuntu. I had to remove the old MAC address and set the new one as eth0.
Everything seems to work fine, except ARP. My provider OVH sent me a warning to resolve it today (this is the second day) or they will block my IP!
The log contains many lines like this:
Tue Jun 5 01:04:29 2012 : arp who-has 178.32.136.212 tell 178.32.136.224
where .224 is the cloned server that is causing problems, and .212 is the cloned one.
arp -na
returns:
? (178.33.230.254) at 00:07:b4:00:00:02 [ether] on eth0
? (178.32.136.212) at 00:50:56:09:8e:f1 [ether] on eth0
The first IP is the ESXi machine. The second one should not be there.
I'm not an expert and I don't know what else to do to fix this problem. Any help will be very appreciated.
Thanks.

I've executed arp -vd 178.32.136.212
to delete the entry in the arp. But after about one our it is listed again.
During the time that the entry was deleted the log was clear.
Why it came back?
