Unable to mount a CIFS drive

[mike557]

I have just installed a NAS drive and want to access it from the dbox2.

Currently I have a linux server and have mounted its folders without any problem onto the dbox.

The NAS is viewable in windows explorer just by entering \\192.168.1.205 and I can see the shared folders. Also the NAS appears and is accessible in windows network neighborhood. However I am completely stuck trying to mount it on the dbox2.

I get no errors when mounting from the menus, however choosing the unmount options shows that the drive is not mounted.

Can anyone supply a shell prompt command that I can use to mount for testing as mount -t cifs does not work?

If not possible to mount from the shell, are there any debug functions that can be enabled so that I can 'see' what is going wrong.

I have found out some more info by using "echo 1 >/proc/fs/cifs/cifsFYI" and then "cat /proc/kmsg". It looks like some security failure as comparing a working mount to the failed mount I get :-

<7> connect.c: Good RFC 1002 session rsp
<7> connect.c: Peek length rcvd: 0x24 beginning 0x56)
<7> connect.c: Mid 0x2d matched - waking up
<7> connect.c: Security Mode: 0x3 Capabilities: 0x80e3f9 Time Zone: 65476

and the failed drive is

<7> connect.c: Good RFC 1002 session rsp
<7> connect.c: Peek length rcvd: 0x24 beginning 0x49)
<7> connect.c: Mid 0x2c matched - waking up
<7> connect.c: No session or bad tcon

Anyone got any pointers as to who I can contact to report the problem or what I could do?

Ok - I know it is bad practice to add to your own thread however I am still stuck with this problem
Could someone just answer some basic questions please.
Is it possible to mount a cifs drive from a neutrino shell prompt, and if so could you give an example (-t option does not work).
If not possible how can I diagnose this problem further ?
Thanks for your time and any input you can give.

1. Setup the network settings for your network.
2. Under the network settings, select mount network volume.
3. select one of the mounts from the list to edit. Click OK
Use the following settings.


type CIFS

Server IP ip address of your pc
directory/share the share name you specified (tvrecord)
local/dir /mnt (subdir if you want)
mount on startup yes
mount options rw,soft,udp
mount options nolock,rsize=8192,wsize=8192
username new user name created on pc
password new user password
MAC Adress leave it alone
mount now OK button

Hi PT-1

Thanks for the pointers however I dont have a problem mounting a linux cifs share, it is just this particular NAS share.
The linux share works fine from my dbox2's however this NAS device is attached to my router and I can view it and access it using network neighborhood in windows 98, but unable to mount in on dbox2.
I get no errors displayed while mounting on the dbox2 but running mount or viewing /mnt/nas I can see that nothing has been mounted.

..this particular NAS share..

what kind of NAS-Device do you use?
What you describe is a known Problem and it imo depends to the SMB/CIFS/Samba Version on that NAS-Device...maybe you can fix it, if you edit the samba.cfg on your device.

[mike557]

Thanks petgun it is good to know that this could be a known problem.
The NAS is actually a usb2 hdd attached to my Netgear WGT634U router/switch.

When mounting I get the following if using cat kmsg

<7> connect.c: CIFS VFS: in cifs_mount as Xid: 31427 with uid: 0
<7> connect.c: Entering cifs_mount. Xid: 31427 with: username=1,password=1,unc=//192.168.2.254/share/partition1,soft,udp,nolock,rsize=8192,wsize=8192

<3> CIFS VFS: cifs_mount failed w/return code = -5
<7> connect.c: Wait for exit from demultiplex thread

At the moment, I cant work out how to find out which version of Samba the NAS is using - I know it is Samba but dont remember how to find this info !!!
I dont have access to a shell prompt on the router so it really is difficult diagnosing the problem.

I guess this is some password/security issue.


----------------------
update

I was wrong, -t is available to the mount command.
I can enter

mount -t cifs //192.168.2.3/vdr-root /mnt/nas -o username=1,password=1,unc=//192.168.2.3/vdr-root,dom=home,soft,rsize=8192,wsize=8192

This is the samba linux server and this will mount.

However using

mount -t cifs //192.168.2.254/share /mnt/nas -o username=1,password=1,unc=//192.168.2.254/share,dom=home,soft,rsize=8192,wsize=8192
mount: Mounting //192.168.2.254/share on /mnt/nas failed: Invalid argument

The mount of the NAS fails
Anyone know why I am getting Invalid argument or how to debug further?

..what do you think about a NFS-Server for the Netgear? It's _impossible_ to stream >6,5 Mbit/sec with CIFS from the DBox..should be > 8 Mbit/sec with NFS.

The most important thing is being able to access the NAS from the dbox. As I do not have root access to the netgear, then getting NFS sorted out I think would be a big problem.
I was unaware of the speed advantage of nfs over cifs so will certainly make that a long term objective.

Thanks for the pointers petgun, I now have root access to the netgear, but feel very uncertain about playing too much with it.

The netgear is running smbd Version 1.9.16 (which seems rather old).

I suppose I am still back to my original question which is how do I mount this NAS drive on the dbox2.

I can 'see' and access the NAS via windows networking but the dbox2 does not give any error messages during the mount (via the menus).
I can mount the NAS on my SuSe linux server using

mount -t smbfs -o username=1,password=1 //192.168.2.254/share /mnt/nas

but I am having trouble with mount.cifs on linux server.

[digi_casi]

for smbfs you need special support on the dbox: smbmount etc...
and cifs on the dbox is most probably not compatible with your nas (at least that's my experience with allnet 6200, couldn't mount with cifs either).

[mike557]

thanks digi_casi
You are unfortunately confirming my thoughts
From what I understand samba supports cifs - so does anyone know how to configure samba to provide cifs rather than smbfs?
I appreciate that this discussion is not directly dbox2 related but again any pointers would be appreciated.
I do now have root access to the netgear so I can re-configure hopefully smb.conf etc.

Hi.
I was wondering if you ever sorted this problem out... I have the same router, but unable to mount it!
Anybody got NAS working, regardless of model?

[mike557]

Afraid I did not manage to fix the problem and still looking for suggestions
