There is a tool in my toolbox netwox which can help you :
  http://www.laurentconstantin.com/en/netw/

Tool 214 does several traceroutes to a range of computers :
 - TCP traceroute to port 21
 - TCP traceroute to port 22
 - TCP etc.
 - UDP traceroute to port 53
 - UDP etc.
 - ICMP traceroute
Then, a text graph, representing each computer, is drawn. This is not very
nice, but very useful.

For example :
  netwox 214 --ips "192.168.1.0/24" --tcpports \
    "21,22,23,25,53,79,80,88,110,113,119,139,143,389,443,445,1080,2401,6000" \
    --udpports "1,53,67,68,123,137,138,161,162,177,514" --icmp --min-ttl 4 \
    --max-ttl 7 --max-ms 300 --resolve --verbose

Just to be clear, this tool only discover computers, and does not search
for any vulnerabilities.

Laurent Constantin
