Continuo ad avere certi problemi nell'instaurare la connessione in dialmode
auto...Il collegamento funzia, ma...
Quando avvio la macchina (Mandrake 7 su un celeron 700) 64MB Ram ho questa
serie di rotte:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use

ippp0

Richiamo la connessione con lynx www.nomesito.com
e tutto va bene, come riportato nei logs.

A questo punto ho una routing table come riportato:

Kernel IP routing table

192.168.10.97   0.0.0.0         255.255.255.255 UH    0      0        0 eth0

ippp0

Se imposto un huptimeout relativamente basso, il collegamento stacca in
questo modo:

Mar  3 05:48:39 agamennone ipppd[531]: Modem hangup
Mar  3 05:48:39 agamennone ipppd[531]: Connection terminated.

Mar  3 05:48:39 agamennone kernel: isdn_net: local hangup ippp0

Mar  3 05:48:52 agamennone kernel: tcpdump uses obsolete
(PF_INET,SOCK_PACKET)

Ma la tabella di rotte diventa:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
192.168.10.97   0.0.0.0         255.255.255.255 UH    0      0        0 eth0
192.168.10.0    0.0.0.0         255.255.255.0   U     0      0        0 eth0
195.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0
ippp0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo

Quindi perdo la rotta di default ma mi resta questa fantomatica riga:
195.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0
ippp0
presente pero' anche durante il collegamento...
e se non forzo manualmente il comando:
route add default ippp0
non viene instradata la chiamata su ippp0 e quindi non parte il collegamento

Come posso fare?
Mi potete dare una mano, please?

Ciao a tutti,
Angelo
