I am assuming the N900 has the equivalent of a mac address but being unfamiliar with both linux and the maemo operating system I do not know where to find it.

Im using wi-fi for the device and at my place of work I need to add its mac address to our list to bypass the internet filter.

So if somebody can tell me where to locate it I would appreciate it. If its complicated and requires prerequisites of some sort like root access you may want to walk me through the whole thing.
