Hi!
We're using a RedHat 6.2 configuration as a dial-in server. ipppd is able to
answer the calls, but only the first call results in a correct data
connection. The second and later calls result in a connection but IP trafic
seems to be passed in only one direction: only to the dial-in server. I
tried thsi both by using a Linux machine as a dialer and a cisco as a
dialer. IP packets from the dial-in server to the dialing machine result in
the message (in /var/log/messages) in the Subject:
kernel: isdn_tx_timeout dev ippp1 dialstate 0
I used tcpdump to trace trafic on both ends of the connection, when doing a
ping from the dialing machine to the dial-in server. tcpdump shows the
packets (icpm request) from the dialing machine to the dial-in server, but
no return packets (icmp reply); they all result in the timeout messages. The
icmp replies show up in tcpdump on the dial-in server after a long while,
but they never show up in tcpdump on the dialing machine.
OK, I know there isn't much detail here. But you all could confirm myproblem
or hopefully tell me that you don't have the same problems. Maybe someone
could tell me what dialstate 0 means, I looked in the sources but
dialstate's values are just numbers so I don't understand what they mean.
This may not even be a kernel problem but a ipppd kernel, maybe you have
some ideas on that.
If any of you would like extra info, just let me know. Any feedback is
welcome. Thanks!
Rolf.
