well i made a remote command thing

shell.run("clear")
print("computer id is: "..os.getComputerID())
write("modem direction: ")
rednet.open(read())
write("controller id: ")
controller=read()
while true do
  id,data=rednet.receive()
  print("received '"..data.."' from id: '"..id.."' controller id: '"..controller.."'")
  if id == controller then
    print("executing")
    local tWords = {}
    for match in string.gmatch(data, "[^ \t]+") do
      table.insert( tWords, match )
    end
    local sCommand = tWords[1]
    if sCommand then
      shell.run( sCommand, unpack( tWords, 2 ) )
    end
print("done")
  end
end

but for some reason id == controller wont return true when it displays "received 'something' from id: '0' controller id: '0'"

:C

Because id returned by rednet.receive() is a number while controller returned by read() is a string, This is easily fixed by changing:

controller = read()

To:

controller = tonumber(read())
