Good catch. Change the sort in the ports_and_pids function to

    sort -u -t/ -k1n -k2

It should look like this now:

ports_and_pids()
{
        netstat -lntup \
        | awk '/^tcp/ { print $4"/"$1, $7 } /^udp/ { print $4"/"$1, $6 }' \
        | sed -n 's|^[^ ]*:\([^ ]*\) \([0-9]*\)/.*|\1 \2|p' \
        | sort -u -t/ -k1n -k2
}
