I just cut and pasted someone's mac address:
patrimoine=# update ethernet set mac='00-00-39-AB-92-FO' where id=623;
UPDATE 1
patrimoine=# select mac from ethernet where id=623; mac
-------------------00:00:39:ab:92:0f
(1 row)
Note the typo "O" instead of "0". I can see how that happened - should it
be "notify"ed against?
(pre-25 Sept code, 7.3b1)
Cheers,
