ipppd problems
hi,
i am in the process of setting up an ISDN router for a network of
three computers, using a 486 and running kernel 2.4.5 (because of the
iptables functionalities). the system has one of the very old AVM A1
(Fritz!Classic) cards, which I can load and talk to with the hisax.o
driver. it's at 0x200, but i don't know the IRQ, but I remember it
being configurable through software, and the docs say that any free
IRQ can be used.
i have used adrian bunk's packages for the 2.4.x kernels, and i have
successfully configured everything for a dial-up to the German
provider T-Online.
I am experiencing a problem, which may be IRQ-caused, but it's weird
and I don't think that IRQs are the cause.
I can establish a connection with 'isdnctrl dial ippp0,' the system
creates the PPP link, configures the routing table, and a second
later, I can ping to the outside. it also looks as if UDP traffic
works.
However, whenever I initiate a TCP connection, the ISDN link goes
down. the logs report the following:
Jun 25 00:51:42 embryo ipppd[3516]: IPCP terminated by peer
Jun 25 00:51:43 embryo ipppd[3516]: LCP terminated by peer

Jun 25 00:51:45 embryo kernel: ippp0: Chargesum is 0
Jun 25 00:51:45 embryo kernel: ippp_ccp: freeing reset data ...
this looks to me as if T-Online cuts the connection somehow, which is
weird. I can dial up just fine to the same account with two other
ISDN-enable computers...
have you experienced something similar? i couldn't find anything on
the AVM site, the HOWTO, isdn4linux, or a general google/linux search.
any help or pointers appreciated.
