Why mess with MAC addresses? If you use dhcp to give terminals names based on the room they're in (et, rm16t1), then your bash script just needs to do "room=`echo $DISPLAY | cut -dt -f1`. > I think you hit on one key issue, CUPS may not be able to hide the > other printers. For that mater I don't even know if CUPS is able to > set a different default printer for each user Setting a default printer is easy. In ~/.xsession or some other script run as the user at login, run lpoptions -d `echo DISPLAY | cut -dt -f1` This assumes that DISPLAY looks like "rm16t1" and that the printer in room 16 is called "rm16". If some rooms share printers, you may need to set up aliases in DNS (eg, rm15 CNAME rm16 if room 15 needs to print on the printer in room 16). Then tell everyone to print to always print to their default printer. Patching cups to do what you want might be easy, it might be very difficult. You might contact the cups developers. -David ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
