 Posted: Tue Aug 24, 2004 9:14 am Post subject: Problema connesione alice adsl |
 |
|
Salve a tutti, ho fatto funzionare il modem ethernet e fatto collegare a internet con una fedora core 2.
Ora sto cercando di istallare gentoo sul computer di mia sorella, per la prima volta con l'adsl sul pc, dato che il mio computer, invece, ha la connessione via lan.
Il problema è semplice:
mi si collega ma non arrivano dati e le uniche cose che posso pingare sono
192.168.1.1 -> modem
192.168.100.1 -> centralina telecom (imho)
vi lascio un pò di log:

sembra un problema di routing.
posta un route -n
ciao

e' sbagliato il default gateway!
e' normale che non comunichi con il mondo.
il default gw deve essere 192.168.100.1 su ppp0

come si setta? non riesco a modificare la stringa.
Posso aggiungerne un'altra corretta ma non funziona lo stesso perchè forse lui considera la vecchia
grazie

Se e' corretta l'indicazione del post precedente devi usare il comando:
| Code: | | route add default gw 192.168.100.1 |

io farei la prova di togliere il default gateway sulla tua conf di rete.
Probabilmente gli script (che non conosco) di dsl ti settano poi correttamente su ppp0.

Secondo me, quello che ti succede è un "difetto" nel meccanismo dell'opzione DEFAULTROUTE all'interno del file /etc/ppp/pppoe.conf.
Anche se settata yes, infatti, questa opzione non sovrascrive i precedenti gateway di default (nel tuo cso 192.168.1.1).
Osserva questa sequenza:
| Code: |
gentoo-ppc cloc3 # route -en
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
172.16.200.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
gentoo-ppc cloc3 # adsl-start
. Connected!
gentoo-ppc cloc3 # route -en
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.100.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0

127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
0.0.0.0 192.168.100.1 0.0.0.0 UG 0 0 0 ppp0
gentoo-ppc cloc3 #
gentoo-ppc cloc3 # ping www.google.it
PING www.google.akadns.net (216.239.59.147) 56(84) bytes of data.
64 bytes from 216.239.59.147: icmp_seq=1 ttl=246 time=93.9 ms

Però:

Un'alternativa sarebbe usare /etc/init.d/net.ppp0 start
Quell'applicazione, però, sovrascrive il gateway precedente e può risultare altrettanto fastidiosa quando si chiude la connessione e si desidera riutilizzare il vecchio gateway.
Forse, servirebbe uno script adhoc per risolvere definitivamente il problema.
