Blacklist for duplicate MAC's

I doubt you have two MACs that are the same.
When quick registering or full registering, it only records the wired NIC.
What’s more likely is somehow you’re DB got dirtied up.
NORMALLY, I’d be able to search the forums and give you the exacto-answer for fixing this… but our forum’s searching feature is temporarily disabled due to issues.
You might figure it out yourself though, look in your DB (like, connecting to MySQL via terminal) and look for hosts that have a MAC address set to zero, and just delete those. There are other things that could cause this, too.
Maybe Tom could chime in?

I doubted myself and I double-checked. Both nodes claim “02:1e:10:1f:00:00”.
It’s a clean, SVN trunk install and I only experimented with these 2 nodes (and a VM; it just boots quicker).
Gonna try to work around the problem by blacklisting (modprobe.blacklist=modname1) the linux-module responsible. -

-
Nothing special. Just boot and did a quick registration. The first host registers a “50:65:f3:nn:nn:nn” (which is the Ethernet-MAC) as hostMAC.hmPrimary=1 and “02:1e:10:1f:00:00” as hostMAC.hmPrimary=0.
When the second host boots, the ipxe-menu tells me the host is not registered. Next I select “quick registration” and a “host already exists as …” somewhere in the following screens and the host is not registered in the FOG database/interface. -
What version of FOG are you using? What distro of Linux and version?
If you look in the cloud in the top left of the WEB UI, it’ll have a revision number.

Its a fresh pull: 3451

I think that this is a developer question.
Give them time, they will eventually get around to this thread (probably sooner than later).

Bumping this thread…

Just so you’re all aware, I’ve been monitoring this thread waiting for more information.
How can you have two systems with the same mac address? Are you using a shared nic between systems?
-
We had duplicate MACs happen to many white box systems one year that had their motherboards replaced… all with 00’s or 88’s for a MAC.
-
Actually, I remember when I first started using FOG we had duplicate MAC issues. This was caused because I had “approved” pending MAC addresses - which included VMWare virtual networking adapters. These were all identical, since I had installed VMware Workstation on a base image and it had retained the same address on every PC.
-
The notebooks (quick) register 2 MAC’s. One is the (unique) ethernet-interface, the second (not unique) is another unknown device. I could look up the brand/type, but thats not the problem. I agree, it should not be possible to have duplicate MAC’s, but the fact is: I have. I did not lookup the device responsible, but i guess it is the WAN/4G Gobi (Qualcomm) interface/modem without a SIM (telco related), where the interface functions as some sort of un-numbered/loopback interface
-
Are these hosts automatically having their pending mac addresses accepted? And are you on FOG 1.2.0?

It’s a SVN#3451 pull
I don’t know what thee default are, but I think you are referring to this setting:

Ah ok! Maybe this is default behaviour now? Tom will probably weigh in soon.
I’ll upgrade to SVN later and see what happens myself.
