I suggest you to make a little program listening that port and spying what
is trying to connect to it.
You may do something like that (needs apt-get install netcat) :
- create a little script /root/spy.sh (just use netstat) :
#!/bin/sh
(
echo "====="
date
netstat -lnp
) >> /root/spy.txt
# yes, I know, there is no lock managment, but hey! just for testing! :)
- lauch a netcat in a terminal (or screen) :
nc -l -p 111 -e /root/spy.sh # for TCP connection
nc -l -p 111 -u -e /root/spy.sh # for UDP connection
- open the 111 access :
iptables -I INPUT -i lo -p tcp --dport 111 -j ACCEPT
iptables -I INPUT -i lo -p udp --dport 111 -j ACCEPT
- then wait and check the /root/spy.txt :
tail -f /root/spy.txt
There is some other (better) way of doing this (by programming),
but this one is the easier I can think by know... :)
Cheers, J.C.
