mount_smbfs re-exported via samba not working

[Mike Tancsa]

Hi,

I am trying to export a series of shares from one Windows XP box, to another so I can better control and log access and am having problems seeing the files. I am not sure if this is a samba issue or an mount_smbfs issue


The setup is

[XP-Server] -------- [FreeBSD]------[DMZ Clients]


So FreeBSD box mount_smbfs from [XP-Server], servs up the share under samab so that the DMZ clients can see it.


I can mount the windows XP file system shares no problem
eg

mount_smbfs -c u -d 777 -f 777 -O xpuser:xpuser -N //xpuser@xpserver/pricelist /export

This shows up, and I can see and create files no problem from the FreeBSD box

# mount -t smbfs
//XPUSER@XPSERVER/PRICELIST on /export (smbfs)



# ls -l /export
total 17
drwxrwxrwx 1 xpuser xpuser - 16384 Dec 31 1969 .
drwxrwxrwx 7 xpuser xpuser - 512 Dec 1 08:04 ..
-rwxrwxrwx 1 xpuser xpuser - 95 Dec 1 10:29 dd
-rwxrwxrwx 1 xpuser xpuser - 92 Dec 1 10:58 n
-rwxrwxrwx 1 xpuser xpuser - 92 Dec 1 10:33 new
-rwxrwxrwx 1 xpuser xpuser - 95 Dec 1 10:29 test
-rwxrwxrwx 1 xpuser xpuser - 436 Dec 1 10:34 test2
-rwxrwxrwx 1 xpuser xpuser - 15 Dec 1 10:22 this-is-a-test.txt


Now the problem is when I try and re-export that using samba. The files never show up on the windows PC. e.g on the other PC attached to the DMZ NIC of the FreeBSD server, I try and do something like

net use m: \\192.168.1.1\pl /user:someothersmbuser

I can map the drive, but doing a dir shows no files. if I do something like dir > test, it does actually create the file, but I still cannot see it

If I use smbclient from another FreeBSD box, also in the DMZ

%smbclient -U somesmbuser //192.168.1.1/pl

Enter somesmbuser's password:
Domain=[DMZ] OS=[Unix] Server=[Samba 3.6.1]
smb: \> dir
NT_STATUS_INVALID_HANDLE listing \*


But... I can actually read the files that I know are there and make and change into directories ??!!

smb: \> get dd
getting file \dd of size 95 as dd (1.2 KiloBytes/sec) (average 1.2 KiloBytes/sec)
smb: \> get test2
getting file \test2 of size 436 as test2 (5.6 KiloBytes/sec) (average 3.4 KiloBytes/sec)
smb: \>
smb: \> mkdir testdir
smb: \> cd testdir
smb: \testdir\> dir
NT_STATUS_INVALID_HANDLE listing \testdir\*
smb: \testdir\>

Any idea why its not working

It seems directly listings are the only things not working, even though ls sees them on the FreeBSD box.

If I export a directory in samba that just has a normal UFS file system all works just fine. Its only when I try and export the smbfs system that it does not work. I also try exporting a nullfs mounted file system and that worked, but again, only if the underlying file system was UFS, not smbfs

I am doing something like this:

FreeBSD zfs -----nfs mount -------> Linux machine -------smb
mount-------> whichever client

Note I am using NFS from FreeBSD instead of samba.

And before I added this to the linux machine's smb.conf global section,
I would get total lockups and nobody could list directories.

strict locking = no
blocking locks = no

So give that a try.

With the first setting, any tests I tried worked fine, but others
reported a similar problem, maybe when there are a few concurrent users.
With the second setting, I haven't had the same problem since. (But if I
share my .zfs directory over NFS, listing that hangs the dataset)

Hi,
Thanks for the response, but it does not seem to help :( Running a session through tshark sees the same sort of response (STATUS_INVALID_HANDLE) on the request to list the directory structure
