Description Georg Kohlweiss 2006-09-24 07:31:14 UTC
I want to mount a private share (only password needed) from the NAS device
WD NetCenter 320 GB Ethernet Hard Drives ( WDXE3200JB ), latest Firmware Version 1.1.0.0003

SMBFS mount works fine:

cocopc:/home/coco# mount -t smbfs //archive/store /archive/store -o username=coco,password=cocostore
cocopc:/home/coco#

CIFS mount does not (dmesg output see below):

cocopc:/home/coco# mount -t cifs //archive/store /archive/store -o username=coco,password=cocostore
mount error 1 = Operation not permitted
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)


mounting a public share of same device with CIFS works fine, seems to be a kind of authentication issue.

 fs/cifs/connect.c: CIFS VFS: leaving cifs_mount (xid = 11943) rc = -1
 CIFS VFS: cifs_mount failed w/return code = -1


I'm forced using CIFS since CIFS is explicitly supported by Netcenter firmware and smbfs stalls and produces input/output errors when accessing multiple files at the same time on the same share.

can you please sniff that one with wireshark and attach here?

net traffic that leads to failed cifs-mount

These are the packets on the line when the mount command
mount -t cifs -o password=cocostore //192.168.1.8/store /archive/store
is executed

net traffic that leads to correct mounted smbfs

These are the packets on the line when the mount command
mount -t smbfs -o password=cocostore //192.168.1.8/store /archive/store
is executed

Attachements are to be opened with wireshark

it seems that cifs does not send the correct password to the server, i tried it with environment variable PASSWD and with a credentials file without success.

smbfs seems to pass the correct password, no error message is returned.

You have your nas server configured for "share level" security.  CIFS support for share level security was added after cifs version 1.40 - could you check what version of the cifs client you are running (modinfo on cifs.ko, or look at he top of the output of "cat /proc/fs/cifs/DebugData").

thanks a lot for this info!

i had to use a new kernel, since debian-package of linux-image 2.6.15-1-686 is shipped with cifs.ko version 1.39

debian package of linux-image 2.6.17-2-686 contains the cifs.ko version 1.43 and with this version it finally works!!
