Who can help me with smbclient (... or Windows ?)

Hi all,

First, sorry for this too long post but I've made a lot of tests and posted all the results. Well, my problem:

I'd like to access to the shared directories on my PC Windows (XP SP3) from my PC Linux (SliTaz rolling) but I get invariably the same answer: Connection to MSNET failed (Error NT_STATUS_UNSUCCESSFUL). Here is my config:

The 2 computers are connected on a box.

[*]PC Linux

hostname = SAMBA
           

[*]smbclient is installed
           

[*]/etc/samba/smb.conf=
[global]

                    workgroup = WORKGROUP

                    security = user

                    map to guest = Bad User

                    [homes]

                    comment = Home Directories

                    valid users = %S

                    guest ok = no

                    read only = no
               

[*]PC Windows

hostname = MSNET
           

[*]workgroup = WORKGROUP
           

[c]

$ smbclient -L MSNET -U shared[/c]

smbclient prompts me for shared's password and then after 20 seconds...

[c]Connection to MSNET failed (Error NT_STATUS_UNSUCCESSFUL)[/c]

A search on internet learnt me it is a generic message that means "something goes wrong"...

I've tested a lot of configurations, I even crossed cables on the box.

MSNET doesn't answer when I ping it from SAMBA but SAMBA answers when I ping it from MSNET:

>ping -a SAMBA

Then I booted SliTaz on MSNET and run Samba, no problem. OK too when I run smbclient on MSNET and samba on SAMBA.

I finally ran smbclient with debug level 3:

[c]$ smbclient -L MSNET -d 3 -U shared

Does the problem come from port 80 on my PC Windows?

Can the firewall on the PC Windows block the communication?

...

The other problem is... , I'm totally ignorant in networking.

Re: Who can help me with smbclient (... or Windows ?)

Hi Ceel,

Want to say I not connected to the Windows machines from Linux.

There's package gvfs-smb exists. Seems it designed to open URLs started with "smb:///" using file manager like PCManFM.

Side note. I see reading error in your log:

[c]Enter shared's password:
tdb(/var/run/samba/gencache.tdb): tdb_open_ex: could not open file /var/run/samba/gencache.tdb: Permission denied[/c]
What about this file existence and it's permissions?

Hi Aleksej,

Thanks to read me ;-)

I see reading error in your log:

[c]Enter shared's password:

tdb(/var/run/samba/gencache.tdb): tdb_open_ex: could not open file /var/run/samba/gencache.tdb: Permission denied[/c]

Yes, I noticed it too. But I think this is a file used by samba and not by smbclient.

I don't have this error when I'm root but the sentence is the same :-(

I forgot to mention that I don't see SAMBA in Explorator > Network but I can see MSNET and my box.

And if I run PyNeighborhood on SAMBA, I can see SAMBA, the box and not MSNET...

@Ceel

Open these ports on MSNET:

$ pscan -cb -p 139 -P 139 MSNET

Scanning MSNET ports 139 to 139

Port    Proto    State    Service

  139    tcp    blocked netbios-ssn

0 closed, 0 open, 1 timed out (or blocked) ports

$ pscan -cb -p 445 -P 445 MSNET

Scanning MSNET ports 445 to 445

Port    Proto    State    Service

  445    tcp    blocked unknown

0 closed, 0 open, 1 timed out (or blocked) ports

Control Panel/Windows Firewall/General tab

If firewall is off something else is blocking the ports.

If firewall is on turn it off.

General tab/Tick off/Click OK

Verify the ports are open with pscan

If you want the windows firewall on make sure "Don't allow exceptions" is unchecked.

Windows Firewall/Exceptions tab/check the box next to File and Printer Sharing/click OK button.

Verify the ports are open with pscan

Winxp terminal commands

Enable/disable file and print sharing exception:

[c]netsh firewall set service FILEANDPRINT enable[/c]

[c]netsh firewall set service FILEANDPRINT disable[/c]

Disable/enable the firewall:

[c]netsh firewall set opmod disable[/c]

[c]netsh firewall set opmod enable[/c]

I get no error when smbclient is run by regular user.

Check that /var/run/samba/gencache.tdb has 644 permissions.

Re: Who can help me with smbclient (... or Windows ?)

This stuff is essential for some users depending in there activities from transfer of a great number of files (not for me since years: I use dropbox and no problem any more - but I transfer only a few number of files, really)!

What is with our SliTaz Guides / Wikis?

@ mojo

If firewall is on turn it off.

Windows firewall is off but the antivirus firewall is on.

I've disconnected internet on the box then disabled the firewall and try

shared@SAMBA:~$ smbclient -L MSNET
params.c:OpenConfFile() - Unable to open configuration file "/etc/samba/smb.conf":
    No such file or directory
smbclient: Can't load /etc/samba/smb.conf - run testparm to debug it

shared@SAMBA:~$
Yes, that's it! Now, the question is: is it reasonable to disable the firewall on a computer that is connected to internet? According to this, not sure.

I get no error when smbclient is run by regular user.

gencache.tdb error appears only in debug mode. Others you can see above exists when only smbclient is installed.

When installing smbclient, directories /etc/samba, /var/run/samba and /usr/lib/samba are not created -> no /etc/samba/smb.conf, /var/run/samba/gencache.tdb, /usr/lib/samba/upcase.dat and /usr/lib/samba/lowcase.dat files.

These messages won't appear when Samba will be installed.

But I can access to shared folders. That's why I think these files are only used by samba.

Maybe there is something missing in the packages installed with smbclient?

Thanks for your help.

Re: Who can help me with smbclient (... or Windows ?)

@ Aleksej,

I've tested gvfs-smb. Cool.

Just enter smb://<SERVER_NAME>/<SHARED_DIR> and that's all (https://wiki.archlinux.org/index.php/Samba#GNOME_Files.2C_Nemo.2C_Caja.2C_Thunar_and_PCManFM).

Much better than smbbox (too much windows) and no need linux-cifs and cifs-utils packages.

Thanks for the hint.

I don't share your point of view. On LAN, I prefer to access directly to a computer from another one whithout to need internet. But dropbox is a good tool too.

What is with our SliTaz Guides / Wikis?

[*]
There is a good guide written by linea to start with it: http://doc.slitaz.org/en:guides:samba

Samba is really easy to implement (for a home network); I didn't meet any problems to install and use server and client on SliTaz machines. Now I have to go ahead with the configuration file and see if I can change some parameters for my firewall when Windows is running

[*]The french guide principaly concerns PyNeighborhood.
