Hola a Todos !!
He notado que haciendo tracerouters hace cosas raras...
Lo que me mosquea es que hasta haciendo un traceroute a euskaltel.com o euskaltel.es o euskalnet.net el traceroute pasa por USA.(172.16.192.106)
traceroute to euskalnet.net (212.55.8.89), 30 hops max, 60 byte packets

Para que tiene que ir hasta usa? Y todo todo todo lo que hacemos pasa por ahi o alguno parecido? Porque hasta haciendo traceroute a google, en el cuarto salto, hay alguna maquina que no sabemos que es. Puede haber un sniffer escuchando todo el trafico que sale de euskaltel hacia el exterior? Que sepais que en la central de la guardia civil en Madrid, si que tienen un sistema llamado SITEL que hace precisamente eso. Controlar todo el trafico. Moviles, internet, telefonia fija, etc etc...
Puedo estar equivocado, pero eso me mosquea. Si alguien sabe de que puede ser.....
Para que ocultar o rechazar los icmp solo en algunos servidores? Sera que quieren ocultar algo ?
Algunos hablan de proteccion y seguridad, pero es que para asegurar una maquina, hay que corregir el software en si, y parchearlo, en vez de rechazar todo tipo de icmp. Y asi evitar ataques. Eso no es seguridad, pa eso, que corten el cable de red. Eso si es seguro...jajaja.
