[tuxero]

Hola a todos.
¿Qué datos envia traceroute (12 bytes) en cada paquete udp?
gracias.

Hola tuxero,

supongo que sabes que con traceroute hay disponibles más métodos y que el método udp se invoca con el parámetro -U.

La página de manual de traceroute distribuída en debian, dice lo siguiente:

udp -U
Use udp datagram with constant destination port (default 53, dns).
Intended to bypass firewall as well.

Note, that unlike in tcp method, the correspond application on the des‐
tination host always receive our probes (with random data), and most
can easily be confused by them. Most cases it will not respond to our
packets though, so we will never see the final hop in the trace. (For‐
tunately, it seems that at least dns servers replies with something
angry).

This method is allowed for unprivileged users.

Salu2

Keep on Rollin'
