Hi guys,

I'm having a little trouble with this piece of code:

function getCientIPs()
while true do
  local event, side, ch1, ch2, msg, distance = os.pullEvent("modem_message")
  if ch1 == 65526 and ch2 == 1 then
   local clientsToAnalyse = {}
   local possibleClients = {}
   possibleClients = textutils.unserialize(msg)
   debugPrint("Possible clients: ")
   debugPrint(textutils.serialize(possibleClients))
   for i,v in pairs(clientIPs) do
    for k,m in pairs(possibleClients) do
	 if  v == m then
	  debugPrint("analyzing...")
	  clientsToAnalyse[k] = true
	 end
    end
   end
   debugPrint("Clients to analyze: ")
   debugPrint(textutils.serialize(clientsToAnalyse))
   for i,v in pairs(clientsToAnalyse) do
    if v ~= true or v == nil then
	 debugPrint("v: ")
	 debugPrint(v)
	 clientIPs[#clientIPs + 1] = possibleClients[i]
	 debugPrint("ClientIPs: ")
	 debugPrint(textutils.serialize(clientIPs))
    end
   end
  end
end
end

What it does is that it takes the table it receives from a slaveRouter with all the client IPs of the slave routers. ClientIPs reffers to the already stored ids. The table is empty in the begining. DebugPrint prints the argument if debugOpt == true. Only for debugging. So the code is not working properly. If you want the whole code just check out this website. The three programs you need start with IPnet. I hope you can help me.

Thanks in advance.

what seems to be your error. can you write it down so we know what to look for in the code?

The error is that when it tries to print the clientips table it only prints {}. Does it have anything tobdo with the fact that the in pairs function does not workn on empty tables
