As explained on this thread: https://sourceforge.net/p/clonezilla/discussion/Help/thread/bfb074e4/ CZ is NOT mounting the share because it seems it loses Root privileges, this occurs on recent version of CZ.

Could you please show us the complete command?
It's easier to understand.
Thanks.

Everything goes fine up until I get this message:

Mounting samba server by:
mount -t cifs -o user="administrator" "//192.168.1.250/Images/CloneZilla" /home/partimag
Password for administrator@//192.168.1.250/Images/CloneZilla:

I don't have a password, so I just hit ENTER, after doing that I get this:

[ 274.402364] CIFS VFS: Send error in SessSetup = -13
[ 274.409213] CIFS VFS: cifs_mount failed w/return code = -13
mount error(13): Permission denied

If I enter the mount command using the command line I get the error:

mount: only root can do that

NOTE: I haven't modified CZ in any way, I'm running the default settings, in other words, I just downloaded it and installed it on a USB drive.

This is weird... I can not reproduce the problem here. I boot Clonezilla live 2.1.2-7 i686-pae version, and successfully mount the samba server (on Windows XP). The only difference is, I have to input password for my samba server.
Could you try to mount a different samba server?

I have only 1 SAMBA server, however, this is what I found out, any version of CZ up to "clonezilla-live-2.1.1-25-i486" works like a charm, "clonezilla-live-2.1.2-2-i486" and newer have the issue I described, so, whatever changes you guys made to the authentication part on "clonezilla-live-2.1.2-2-i486" and up should be looked at.

Thanks

In that case, I believe the issue is the samba program has changed.
I compared clonezilla-live-2.1.1-25-i486 and clonezilla-live-2.1.2-2-i486, the packages:
1. cifs-utils both are the same, i.e. 2:5.5-1
2. samba-common: 3.6.6-6 vs: 3.6.14-1
The difference about samba-common on Debian:
http://ftp-master.metadata.debian.org/changelogs//main/s/samba/samba_3.6.15-1_changelog

Since I can not reproduce the issue here, maybe you can try:
1. Try Clonezilla live 2.1.2-11
2. If it has same issue, configure the network in Clonezilla live 2.1.2-11 by running "ocs-live-netcfg", then
3. wget ftp://ftp.us.debian.org/debian/pool/main/s/samba/samba-common_3.6.6-6_all.deb
4. sudo dpkg -i samba-common_3.6.6-6_all.deb
5. Run "clonezilla" command again, try to mount your samba server again. To see if this issue is gone. If so, we know that samba-common regressed... Then we should report the issue to upstream, i.e. Debian project.

I've had a similar issue with CZ 2.1.2-20 and a home NAS. The only way I could mount the share was to drop to the command line and mount the share from there, the key being to add the argument "sec=ntlm" to the mount command.

Having to do that certainly takes CZ out of the province of beginners.

I'd like to see a way within CZ to specify NTLM security - I understand from the web searches that I did that CZ's default security is NTLM3, but ICBW - it's beyond my understanding. Alternatively an automatic fallback perhaps, i.e. if the default fails then try NTLM.

One thing I can confirm is that just being root wasn't enough; "sec=ntlm" was the thing that made the difference for me.

Hi, today I downloaded 2.1.2-20 (Live) and tried to connect to my nas via the samba option in the GUI and got a -13 error permission denied. I then went back and tried an older version of the CD and it was fine. On both I entered everything straight up only servername,domain,user,password. Thanks.

Indeed, it seems something is broken, new versions cannot mount my shares.

As Dave mentioned, could you try to add the argument "sec=ntlm" manually when mounting your samba server?
Please let us know the results.
BTW, please also try Clonezilla live 2.1.2-24 or 20130723-raring. The former comes with updated Linux kernel 3.10, and it might give you different results.
Thanks.

Steven.

I tried using 2.1.2-24 (i486), dropped to CMD and typed the command as indicated above and I get the message "mount: only root can do that"

OK, from the discussions here:
http://aptosid.com/index.php?name=PNphpBB2&file=viewtopic&t=2566
I realized the from Linux kernel 3.8, the default security for CIFS has been changed to ntlmv2, which has been used widely many years. However, for some embedded system, like NAS sever, the samba is still old version (e.g. 2.x)), that's why. The testing I have done here is not connecting to a NAS server, it's a MS Windows XP samba server.
We will have an option to let people choose "ntlm" or "ntlmv2" in the future release.

@Jack,
"mount: only root can do that" -> You have to run that command as root, i.e.
1. sudo -i
2. mount -t cifs ...

Ok, it seems that login in using sudo -i and then typing the Mount command and adding sec=ntlm works.

Steven Shiau - 2013-07-31

Please give Clonezilla live 2.1.2-31 a try. It gives you an option to use "sec=ntlm" when mounting Samba server.
Please let me know the results.
Thanks.

Steven.

Ok, if I select the NTLM option, it works.
