[Linux-decnet-user] Help with DNMOUNT

[Mauricio M. <MM...@ex...>]

I have installed the new kernel (2.2.16) and applied the new patch for that
version.  I've tested out the DecNET for Linux mounting feature again.. and
I'm getting the same results.  All the DecNET programs such as dndir work
properly, except we have the same problems with dnmount.

By the way.. I'm using DNPROGS v2.05  (3 Apr 2000)

I've used TCPDUMP to capture all packets going to ALPHA1 (1.17) and here is
what I found.  I don't understand the TCP dump very well.  I've included a
DNDIR dump.. (which worked fine) and then the DNMOUNT, LS -LA and then the
UMOUNT.

Let me know if you understand any of this.. thanks!

I have noticed that while the LS -LA is active I see the 2nd connection that
is listed below.  The Remote Node 0.00.
I'm wondering if it has something to do with the DefRoute being 0.0???

How do I set the routine?  Maybe I have something configured wrong?

Here is a list of cat /proc/net/decnet  (while the LS -LA is waiting for a
response)

Thanks for any help you can provide,
