Error multiple hosts returned for list of mac addresses

Please run the following commands on the console to query the database for the duplicated MAC used:

shell> mysql -u fogmaster -p
Password:
...
mysql> use fog;
...
mysql> SELECT * FROM hostMAC WHERE hmMAC IN (SELECT hmMAC FROM hostMAC GROUP BY hmMAC HAVING COUNT(hmMAC) > 1);
...
mysql> SELECT * FROM hosts WHERE hostID IN (SELECT hmHostID FROM hostMAC GROUP BY hmMAC HAVING COUNT(hmMAC) > 1);
...
mysql> quit

The password for the fogmaster database user is found in /var/www/html/fog/lib/fog/config.class.php. Post output of the commands here in the forum if you need further help.

@Sebastian-Roth here is the output

MariaDB [(none)]> use fog;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
MariaDB [fog]> SELECT * FROM hostMAC WHERE hmMAC IN (SELECT hmMAC FROM hostMAC GROUP BY hmMAC HAVING COUNT(hmMAC) > 1);
Empty set (0.02 sec)

MariaDB [fog]> SELECT * FROM hosts WHERE hostID IN (SELECT hmHostID FROM hostMAC GROUP BY hmMAC HAVING COUNT(hmMAC) > 1);
Empty set (0.01 sec)

@darkxeno Are you still seeing the same error in fog.log on the client. May I ask you upload the full log file here or if you think this exposes too much internal information (private range IPs and MACs are not an issue I find) then send me a private message and we can exchange things securely via PGP encrypted email.

[darkxeno]

@Sebastian-Roth sure thingfog.log

[darkxeno]

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

[Sebastian Roth]

@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…

[darkxeno]

@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
