Hi -

My messages may not be reaching this list. Would someone at least
confirm receipt of this message even if you have no suggestions/
comments re its content?

I have sent several messages concerning mount.smbfs and I guess
no one is using smbfs to mount a Windows machine -or- no one
has encountered my problem. To recap the problem and give a

mount.smbfs is not working on 3.0.0beta3; it has been working thru
3.0.0beta2. When I re-install 3.0.0beta2, it works again.

*Linux host <hanako>
  Linux version 2.4.20-4GB-athlon (root at Athlon.suse.de)
  (SuSE Linux 8.2)) #1 Fri Jul 11 20:16:51 UTC 2003
*samba-3.0.0beta3 complied from source, with configuration
  option '--with-smbmount'. (same configuration used for beta2).
*Windows 2000 Professional <rocky> - current with windows update.

mount -t smbfs //rocky/c$ /mnt/rocky -o rw,credentials=/my/credentials/file
mount.smbfs //rocky/c$ /mnt/rocky -o rw,credentials=/my/credentials/file

Recompile the kernel with 'MAX_SMB_PACKET_SIZE' set to 65536. My kernel
had it at 32763. This can be done easily by hand or with this patch
(remember - this is for the SuSE linux 8.2 kernel 2.4.20 - your
mileage may vary):

 /* reserve this much space for trans2 parameters. Shouldn't have to be more
    than 10 or so, but OS/2 seems happier like this. */

Why does 3.0.0beta3 need 57,231 parm bytes? Is it me or some change
introduced with beta3 (remember beta2 works fine on my machines).
I hope this is the correct forum to discuss this so that it
can be considered by the developers before the first 'real' 3 is
rolled out. Could someone please advise.
