Unable to rename/join - Error multiple hosts returned for list of mac addresses

[darkxeno]

@Sebastian-Roth heres the log file after updating to 0.12fog.log

@darkxeno Some of the MAC addresses we see in the logs are clearly virtual VPN adapter MACs - e.g. 00:09:0F:AA:00:01

Please run the following SQL query to find out which hosts might be using these and post results here:

mysql> SELECT hmHostID FROM hostMAC where hmMAC IN ('00:09:0F:AA:00:01', '4E:4D:D9:8C:1F:5B', '54:B2:03:E4:6A:D5', 'F8:AC:65:BE:26:0C', 'F8:AC:65:BE:26:0D', 'FA:AC:65:BE:26:0C', 'F8:AC:65:BE:26:10', '90:93:8B:56:52:54');

@darkxeno Always need to select the database first just as last time:

shell> mysql -u fogmaster -p
Password:
...
mysql> use fog;
...
mysql> SELECT hmHostID FROM hostMAC where hmMAC IN ('00:09:0F:AA:00:01', '4E:4D:D9:8C:1F:5B', '54:B2:03:E4:6A:D5', 'F8:AC:65:BE:26:0C', 'F8:AC:65:BE:26:0D', 'FA:AC:65:BE:26:0C', 'F8:AC:65:BE:26:10', '90:93:8B:56:52:54');
...
mysql> quit

@darkxeno Now get the names of these hosts:

...
mysql> SELECT hostName FROM hosts where hostID IN ( 357, 419 );
...

Got them what do I need to do with them?

Well, check those in the FOG web UI. Why do they have the same MAC addresses? Remove the MAC address from one or both of the hosts and their fog-client should be working fine again.

Often this is caused by virtual VPN adapters. For example the 00:09:0F:AA:00:01 looks like one. You can prevent the fog-client from registering those kind of MACs using this setting: FOG Configuration -> FOG Settings -> FOG Client - Host Register -> FOG_QUICKREG_PENDING_MAC_FILTER…

@Sebastian-Roth That worked thanks man I owe you a beer!!!

[Sebastian Roth]

@darkxeno You are welcome. I know it’s a bit of a hack to work through this and find that duplicate. Though it would need a lot of changes on the messages we send between FOG server and fog-client if we wanted to print out the names of those machines using the same MAC right in the fog.log…

@Sebastian-Roth I understand than I was racing my brain on this lol
