After a rediculous amount of searching for a system that can do quotas.
I think I have finally hit the jackpot. I have been in contact with all majour networking vendors, none had a clue what device could offer such a feature. - So firstly thankyou!
During my searching I purchased a alix system http://www.pcengines.ch/alix6e1.htm whith pfsense, however it turned out this cannot do quotas.
I have downloaded the latest alix/86 1.3 and written the image to a compact flash card. I have connected via telnet to the system, and get this.

No doubt it is an error at my end. I am new to this, However I assume the cryptic code being displayed isnt what is supposed to be. Needless to say I cant get a IP address, or communicate over network to the device in any manner.
Any ideas what I am doing wrong? -
Is this likely to work with my alix board anyway. Or am I just looking to casue more problems than it's worth.
