Modified SQUID or Dansguardian?
Yes I did look at them, but they are well away from the accounting requirements that there might be and we are not looking to control the content of the users, I dont think I either have the skill or the time to modify them.
There is a proprietary router/Wifi/Printer box that claims to do the job, or I could just use standard routers, WAP, etc and control the use via a changing WEP key and manual procedures, but I thought it was an ideal opportunity to get an SMEServer box through the door of this particular institution.
