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.
