[ltp] ibmtr_cs 2.2.18 and DHCP

Mon, 18 Dec 2000 11:05:52 +0100

Hi all,

lately I upgraded to ibmtr_cs-2.2.18 and pcmcia-cs-3.1.21 in order to
get VMware to run again (base system config is SuSE 7.0 with 2.2.16).
There should be quite a few messages in the archives with regard to that
topic.

This has worked fine so far. Even more, the Token Ring driver looks more
stable to me now, although others have reported problems. Unfortunately,
I can join them now ...

Usually, I use a fixed IP address for my machine. Last week I had to
connect my TP to another location's LAN and therefore use DHCP for the
IP configuration. To my surprise, this wasn't working, although I had
used DHCP without problems before. Today, I double-checked it in our LAN
with the same unsatisfying result.

It looks like the adapter isn't opened correctly and the tr0 interface
receives a lot of packages, but is not able to send some. Here are the
lines from /var/log/messages:

Another item: As you may have seen above, I have *not* disabled (i.e.
commented out) the options for the ibmtr_cs module within
/etc/pcmcia/config.opts, although some time ago Burt told us to do so
and let the driver pick the values. The reason is that my machine hung
from time to time when not specifying these options for ibmtr_cs.
Regardless whether I tried DHCP or was using a fixed IP address.

Burt, could you shed some light on any (preferably both ;-) ) of these
items? TIA.

Markus
