Hello!

I want to control the starting of certain services on my  
Linux VPS with a home made porttrigger. If the right password  
is received the according programm for that port is started.  
( I have my reasons to do it this way and not with firewall  
setting or encryted passwords. If you want to know ask 😉 )

This is what i have come up with so far:

#!/usr/bin/env ruby  
require “socket”  
server = TCPServer.new(‘0.0.0.0’, 8089)  
while (session = server.accept)  
if (ret=session.gets.chomp) =~ /password/  
puts `./sc_serv0`  
end  
session.close  
end

It kinda works, but the problem is that the ruby isnt freeing  
the port.  
So programms that cant share ports give me:

error opening source socket! FATAL ERROR! Some other process is using  
this port!

How do i close the TCPServer after the right password is received?  
( In the final version i want to stop the started programm after  
a certain amount of of time and start the trigger again ( and it  
prolly needs to be threaded. ))  
But for now i just want this to work.

server.shutdown wont work after the right pw is received.

Any ideas?

Thanks!
