Problem mounting Samba share

Ursa Major · 2010-06-28 10:00:36

I'm trying to mount a samba share at my university with mount.cifs:

 mount.cifs //samba-fs1/nfspl /mnt/nfspl -o username=XXX,domain=XXX

However, it simply returns

mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

It works fine with smbclient. I enabled cifsFYI output, and mount.cifs gives this in the system log:

Since it complains that the server is asking for plaintext authentication, I tried enabling that with 'echo 0x30030 >/proc/fs/cifs/SecurityFlags' (as per http://www.kernel.org/doc/readme/fs-cifs-README). Still the same error, this time with syslog

Any idea what could be wrong?

it could be a problem with the mount.cifs program, do a sysupgrade, if it still doest work, try using the option nounix or the sec options for NTLM/Kerberos security, check mount.cifs man pages for exact syntax

Ursa Major · 2010-07-04 12:03:51

Thanks, but I am using the newest version (and I've tried before too,so if it's a problem with mount.cifs, it's old). I did try the different sec options -- some of them return the same error, some "(39): Function not implemented" and some "(95): Operation not permitted". And according to the syslog messages, the server requests plaintext auth.

Sin.citadel · 2010-07-05 17:27:55

the security flag did work as there is no error ,essage about plaintext auth in the log, try using -sec=none, or you could try using smbfs but its known to be broken and isnt actively supported, if nothing works and the server cant work without plaintext auth, then you can use a VM with windows on it to get the data from the share.

Ursa Major · 2010-07-05 18:37:07

Doesn't work with sec=none either.

I guess it could work with smbfs, but as you said, smbfs is broken, and not part of the samba packages on Arch. Anyway, there's no problem when using smbclient or the smb kioslave (so I won't have to resort to Windows ) -- it's just that mounting it directly with mount.cifs is rather more convenient, and it _ought_ to work, dammit!

I guess I'll ask upstream, if nobody has any other ideas?

Hi!
I got the exact same problem.
The only solution I found is to keep using kernel 2.6.

pacman -S kernel26-lts{,-headers}

I unfortunately haven't found a solution yet for the kernel 3.0-ARCH. If any of you guys found a solution, I would be pleased to read it.
