inetd superserver client ip retrieval

If you have ever used the internet superserver inetd and connected it to a bash script and wondered how to retrieve the ip and port of the client, here is the solution:

/etc/inetd.conf
666 stream tcp nowait root /opt/client_ip.sh

/opt/client_ip.sh

#!/bin/bash

read ip port <<< `getpeername`

# $ip now contains the ip

# $port now contains the port

Maybe you need to apt-get install tcputils to install getpeername.
