Traceroute information

Traceroute in Nmapthon2 works exactly the same as it did initially, but the container class name changes a little. Traceroute information is stored inside a Host object, and each hop from the traceroute is stored inside a Hop object.

Important

In order to have traceroute information, the --traceroute Nmap parameter is mandatory.

import nmapthon2 as nm2

scanner = nm2.NmapScanner()

result = scanner.scan('scanme.nmap.org', arguments='--traceroute')

for host in result:

    hop_list = host.traceroute()

Inspecting hops

Each Hop represents a node that responded with an ICMP packet. For this example, a Docker container has been used, since most intermediate hosts block ICMP pings nowadays, so using public domains with traceroute would not be very explanatory.

import nmapthon2 as nm2

scanner = nm2.NmapScanner()

# Host must respond in order to have traceroute info
result = scanner.scan('172.17.0.2', arguments='--traceroute -Pn -T5', ports='1-100')

for host in result:
    print(f'Host: {host.ip}')

    for i, hop in enumerate(host.traceroute()):
        print(f'\tHop #{i + 1}')
        print('\t------------')
        print(f'\tHost: {hop.host}')
        print(f'\tIP: {hop.ip}')
        print(f'\tRTT: {hop.rtt}')
        print(f'\tTTL: {hop.ttl}\n')

Would produce an output similar to:

Host: 172.17.0.2
    Hop #1
    ------------
    Host: None
    IP: 192.168.0.1
    RTT: 0.00
    TTL: 1

    Hop #2
    ------------
    Host: None
    IP: 10.5.0.1
    RTT: 7.00
    TTL: 2

    Hop #3
    ------------
    Host: 50.15.26.77.sanitized.sanitized.com
    IP: 17.__.35.__ # This IP has been sanitized
    RTT: 8.00
    TTL: 3
