Ubuntu – Unable to mount XP share: Error NT_STATUS_UNSUCCESSFUL

mountsambasharevpnwindows xp

I'm failing with mounting XP share, receiving message:

…

mount error(110): Connection timed out

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

When I try to list shares with smbclient, finally I receive message:

…

Running timed event "tevent_req_timedout" 0x7f2902964ad0

Error connecting to 192.168.34.140 (Success)

lang_tdb_init: /usr/share/samba/en_US:en.msg: No such file or

directory

Connection to 192.168.34.140 failed (Error NT_STATUS_UNSUCCESSFUL)

I wasn't able to find solution, could anyone advise?

Context:

I'm trying to mount share of NT-domain machine with XP which is accessed via VPN. While my ubuntu machine is still in default WORKGROUP. Is this possible at all?
Connection to target machine could be established, f.e. I can connect to it via RDP.
Command executed to mount:
mount -t cifs //192.168.34.140/share_name /media/share_name -o username=XPDomainUsername,password=XPDomainPassword,workgroup=XPDomainName
Command executed to list shares:
smbclient -L //192.168.34.140 -U XPDomainName\\XPDomainUsername --debuglevel=10

Best Answer

You might have to specify the IP address separately because most Windows servers require you to specify the NetBIOS name too, e.g.

smbclient -L XPHostName -I 192.168.34.140 -U XPDomainName\\XPDomainUsername --debuglevel=10

Nautilus Password – Nautilus Wants a Password When Connecting to a Public Windows Share

Last time I checked (some months ago), I explicitly had to add a permission for "Guest" to the Windows 7 share (Advanced Sharing > Permissions) to allow password-free connections. "Everyone" alone didn't work for whatever reason. Maybe this has changed in the meantime, but it's worth a try.

Ubuntu – mount cifs share on terminal fails (using password or kerberos krb5 ticket)

I recommend you use fstab for mounting.

Try to check the logs to troubleshoot the causes of your problem, try this command to display the list of files which could display the mount logs:

grep -e mount -e ext4 -lR /var/log 2> /dev/null

For me, the mount logs were in /var/log/syslog it may be different for you.

Now you need two terminal tabs open, enter the command on one tab: sudo tail -f /var/log/syslog

And on the second tab, try to mount the system with the following command:

mount -t cifs -o user=USER,domain=DOMAIN,cruid=USER,sec=krb5 //HOST/Share /mnt/tmp

If you go back to your first tab you should be able to see some log errors. For me the errors were(for you it may be different):

   kernel: No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.
   kernel: CIFS VFS: protocol revalidation - security settings mismatch
   kernel: CIFS VFS: session ffff90a6a2959000 has no tcon available for a dfs referral request
   kernel: CIFS VFS: cifs_mount failed w/return code = -5

Depending on your error logs, you may be able to get away with adding vers=1.0 to your mount command and this could work but it is the less secure version of smb. Otherwise, you could workout what the solution is based on the error you get.

What you could also try is configure the Samba server inside /etc/samba/smb.conf similar to this (it works for me):

[username]
   comment = Username's developer directory
   read only = no
   locking = no
   path = /var/www/username
   guest ok = no
   writeable = yes

Then on the client, add the following line to /etc/fstab

//server/username /mountpoint cifs vers=1.0,username=username,iocharset=utf8,uid=your_profile_uid_on_the_server 0 0

Use sudo mount /mountpint See how this goes, hopefully this information will be useful to you.
