Hi!

If you can isolate the box to a subnet alone with your Debian machine
you can try the following:
nmap -sT -PI -PT 192.168.0.0/16
nmap -sT -PI -PT 10.0.0.0/8

Alternatively you can use wireshark, iptraf, tcpdump, etc. to sample
and analyze network traffic. This requires that you actually can
sample all network traffic to and from the box, e.g. switch with IDS
port or a old plain hub.
