Okay then you must have one k12ltsp server for more than 1 room
(Multiple room setup). In this case you would have to use the
File->Dispay-MAC-Addresses.

1) collected all macs into fl_teachertool.maclist (File->Write-mac-addresses)
2) print this maclist file
3) (login to every machine) and run File->Display-mac-addresses
4) walk around ticking off which macs addresses are in which room
5) copy/paste the maclist into fl_teachertool.conf re-arranging
according to room name
(see example setup in conf file)
6) Use this modified python script below

#!/usr/bin/python
import os,sys

reading=False
macfile=file('/etc/fl_teachertool/fl_teachertool.conf','r')
for x in macfile:
   if (reading==True):
      if ( x[:4]=="room"):
         reading=False
      else:
         os.system("ether-wake "+x)
         os.system("sleep 1s")
   if (x[5:-1]==sys.argv[1]):
      reading=True
macfile.close

However this script will not tolerate spaces in front of a mac or room
description as fl_tt does. So it would have to be formatted as such


room=library
00:10:4B:23:47:BA
00:10:4B:23:41:9D
00:60:08:C6:08:97
00:60:08:C6:01:71
room=302
00:10:4B:23:48:A8
00:10:4B:23:47:88
00:60:08:C6:02:20

Once again, test this as I have not.
