I'm trying to add a few new computers but they're not getting their own Computer ID. Instead, the project thinks that they're all one of my existing machines, this one: http://universeathome.pl/universe/show_host_detail.php?hostid=81256. This results in abandoned tasks every time one of them communicates with the server.

I removed and re-added the project to each host, both through the Manager and the command line, but it's still not working.

I never had this problem with my 10 Raspberry Pis and they were all added to this project within minutes of each other.

Please help!

Update: TN-Grid did not have this problem, it created a brand new host. This seems to be specific to this project.

Additional info:

It is a fresh linux install, not a duplicated sd card

Changing the hostnames did not fix the problem

The MAC addresses are unique for each machine

Have you removed the project after changing the hostname?
Restart the machine before adding the projekt again.

Yes. After having these problems, I removed the project, changed the hostname, rebooted, then re-attached the project. It still wouldn't generate a unique ID.

Ok, I crunched TN-Grid for 3 days, but today I decided to try to reconnect them here again.

And it worked! I now have 3 unique hosts: Odroid1, Odroid2, and Odroid3.

I have no idea why this didn't work a few days ago...
