scapy.layers.inet.traceroute(target, dport=80, minttl=1, maxttl=30, sport=<RandShort>, l4=None, filter=None, timeout=2, verbose=None, **kargs)[source]

Instant TCP traceroute

Parameters:

  • target – hostnames or IP addresses

  • dport – TCP destination port (default is 80)

  • minttl – minimum TTL (default is 1)

  • maxttl – maximum TTL (default is 30)

  • sport – TCP source port (default is random)

  • l4 – use a Scapy packet instead of TCP

  • filter – BPF filter applied to received packets

  • timeout – time to wait for answers (default is 2s)

  • verbose – detailed output

Returns:

an TracerouteResult, and a list of unanswered packets
