2.8. Traceroute

We can get every hop information from executing a traceroute to a particular host:

• trace_info(host:str): Yields one TraceHop instance per traceroute hop.

2.8.1. TraceHop object

A TraceHop instance has four basic properties to access its information:

• ttl: Time-To-Live. IP layer field.
• ip_addr: IP Address of the node.
• rtt: Round Trip Time.
• domain_name: Domain name of the node.

Note

If any of the traceroute hop information is unknown, the corresponding property will return None.

2.8.2. Traceroute example

import nmapthon as nm

scanner = nm.NmapScanner('85.65.234.12', arguments='--traceroute')
scanner.run()

if '85.65.234.12' in scanner.scanned_hosts():
    for tracehop_instance in scanner.trace_info('85.65.234.12'):
        print('TTL: {}\tIP address: {}'.format(tracehop_instance.ttl, tracehop_instance.ip_addr))
