Re: Perdida de paquetes a la red interna



        Por "casualidades de la vida" deje un ARping a la .55 "olvidado
    sin querer" y al realizar las pruebas de nuevo de ping me daban
    todas correctas ( en mi sistema squeeze). Cuando me di cuenta de que
    no fallaban por el arping, casi me corto las venas.... XD

    ########## ARping
    --- 192.168.120.55 statistics ---
    502 packets transmitted, 502 packets received,   0% unanswered (0 extra)
    root@jmramirezmachine:/home/jmramirez#

    ########## Ping mientras estaba el arping
    --- 192.168.120.55 ping statistics ---
    502 packets transmitted, 502 received, 0% packet loss, time 500998ms
    rtt min/avg/max/mdev = 0.133/0.158/0.282/0.024 ms

        Pero en cuando paro el arping y vuelvo a ejecutar el ping a
    "secas" me sigue fallando.



Esto que comentas del arping hace sospechar por un problema arp :)
Porque no pruebas de asignar una entrada estática para la ip
192.168.120.55 en la tabla arp y pruebas si los pings siguen fallando?¿
Si dejan de fallar puedes usar wireshark para intentar descubrir lo que
está jodiendo tu tabla arp.

si no me falla la memoria seria algo así:

arp -s 192.168.120.55 00:13:8f:db:88:8b

Buenas .....

He probado ha hacer la entrada estática, como me has indicado y el "Flags" cambio

Pero al hacer el ping no sabe llegar.....( hice varios intentos y espere unos 3 min, por si las moscas)

Hago un arping y ahora ya sabe llegar, pero solo durante un rato, los primeros paquetes fueron bien pero al llegar al 32 ya no pudo llegar, paro el ping y le vuelvo a lanzar y no llega ningun paquete..... :S

¿Alguna otra idea?
