A simple script to cleanup duplicated entries in a UPNP Server using upnpc!

cleanupUPNP.sh

#!/bin/bash

# to speed up the execution by not having to probe the network for the upnp server
# or if you have more than one upnp server in your network,
# use upnp_url var to specify the url of your upnp server.
# to find all the upnp servers urls, you can run:
#   upnpc -l | grep 'InternetGatewayDevice' -B 1 | grep 'desc:'

#upnp_url="http://192.168.10.1:6352/rootDesc.xml"

[ "$upnp_url" != "" ] && upnp_url="-u $upnp_url"
upnpc="/usr/bin/upnpc $upnp_url"
duplicated=$($upnpc -l | awk '{print $2"@"$3}' | egrep 'TCP|UDP' | sort | uniq -d)
if [ "$duplicated" != "" ] ; then
	echo "List of duplicated entries..."
	echo "$duplicated"
	echo "Removing duplicated entries..."
	for n in $duplicated ; do
		protocol=$(echo $n | awk -F'@' '{print $1}')
		port=$(echo $n | awk -F'@' '{print $2}' | awk -F'->' '{print $1}' )
		echo $upnpc -d $port $protocol
		$upnpc -d $port $protocol
	done
fi
$upnpc -l | awk '{print $3"    \t"$2}' | egrep 'TCP|UDP' | sort -h | sed 's/->/\t -> /g' | sed 's/:/\t : /g'
