[/edit]



Hi there, :)

I have a SME server 9.x (x=2 if I am not wrong) configured in server only, behind a residential gateway (aka "Wi-Fi Router") with necessary ports open to use it as a web server ; SME's DHCP server = off ; Everything connected is using static IPAddresses.


I am used to successfully mount "smb" shares between other Linux machines from the same local network, the following way:

Code: [Select]
# mount.cifs //192.168.123.45/share /mnt/smb/machine/share -o username=RemoteUserName,password=PassWord
Unfortunately, it doesn't seem to work with my actual SME server box:

Code: [Select]
mount error(13): Permission denied
Refer to the mount.cifs( manual page (e.g. man mount.cifs)


After searching for a while, I also tried the following alternative method involving a "credentials" file located in '/root/password' in which file there is the following:

Code: [Select]
username=RemoteUserName
password=PassWord
domain=192.168.1.2

192.168.1.2 being the IPAddress of my SME server on the LAN.


Since SME-Server as certain particular ways to do certain things, I am wondering what could be wrong with what I have done, so far ?


I am thinking about something wrong about the Domain, while I only use WorkGroup mode...

Else, do I need to have exactly the same 'username' and 'password' on both Linux machines ?
(I tried that too, it didn't work either)

Regards,
  H.P.

P.S.
What I tried has been done on '/mnt/smb/machine/share', to check if things were working fine before attempting the same in an 'ibay/html' location as I actually need on LAN only restricted access ibay.


Search done on http://Contribs.org brought me to the following readings:

 - - https://wiki.contribs.org/Useful_Commands  (something about ACL ...)
 - - https://wiki.contribs.org/Mount_Network_Shares

Search done on http://forums.Contribs.org brought me to no answer. So, I am posting here.

Search on Google didn't help me much. Just found some things about the '/root/.password/credentials' method.

Finally found a working solution:

Code: [Select]
# mount.cifs //192.168.123.45/share /mnt/smb/machine/share -o username=RemoteUserName,password=PassWord,sec=ntlmssp

The usual 'mount.cifs' command needed the following extra parameter:  sec=ntlmssp


Reliable source of information:

FWIW I have to use this in my /etc/security/pam_mount.conf.xml file on *buntu

Code: [Select]
<volume fstype     = "cifs"
       server     = "my.server.net"
       path       = "directorypath"
       mountpoint = "/home/e-smith/files/users/%(USER)/Mounts/somefileshare"
       options    = "uid=%(USER),nosuid,nodev,noexec,sec=ntlmssp,vers=1.0"
       user       = "*"
       sgrp       = "dt-admins"/>

After some changes a while back I had to add the "sec=ntlmssp,vers=1.0" part.

I have modified the wiki page to reflect it.

https://wiki.contribs.org/Client_Authentication:Ubuntu_via_sssd/ldap
...
1. Read the Manual
2. Read the Wiki
3. Don't ask for support on Unsupported versions of software
4. I have a job, wife, and kids and do this in my spare time. If you want something fixed, please help.

Hi ReetP,

Thank you for your sharing.

FWIW I have to use this in my /etc/security/pam_mount.conf.xml file on *buntu

Code: [Select]
<volume fstype     = "cifs"
       server     = "my.server.net"
       path       = "directorypath"
       mountpoint = "/home/e-smith/files/users/%(USER)/Mounts/somefileshare"
       options    = "uid=%(USER),nosuid,nodev,noexec,sec=ntlmssp,vers=1.0"
       user       = "*"
       sgrp       = "dt-admins"/>

After some changes a while back I had to add the "sec=ntlmssp,vers=1.0" part.

I have modified the wiki page to reflect it.

https://wiki.contribs.org/Client_Authentication:Ubuntu_via_sssd/ldap

Well, so "far", what I have done seems to keep working.
So, with what you said, the need for this extra 'sec=ntlmssp' parameter for very basic mount.cifs command seems to be confirmed, I guess. :wink:


Just for feedback information, about the Wiki link mentioned above, there may be something wrong with the edit version displayed, as I do not see what you put in your post:

Code: [Select]
cat <<'_EOF' >/etc/security/pam_mount.conf.xml
<pam_mount>
<debug        enable  = "0" />
<mntoptions   allow   = "nosuid,nodev,loop,encryption,fsck,nonempty,allow_root,allow_other,noexec" />
<mntoptions   require = "nosuid,nodev,noexec" />
<logout       wait    = "5" hup    = "0"    term="yes" kill="0" />
<mkmountpoint enable  = "1" remove = "true" />
<volume fstype     = "cifs"
       server     = "sme.server.com"
       path       = "%(USER)"
       mountpoint = "/home/e-smith/files/users/%(USER)/Partages/Personnel"
       options    = "uid=%(USER),nosuid,nodev,noexec"
       user       = "*"
       sgrp       = "admins"/>
<volume fstype     = "cifs"
       server     = "sme.server.com"
       path       = "artwork"
       mountpoint = "/home/e-smith/files/users/%(USER)/Mounts/artwork"
       options    = "uid=%(USER),nosuid,nodev,noexec"
       user       = "*"
       sgrp       = "admins"/>
</pam_mount>_EOF

Best regards,
  H.P.

You may need to add a 'sec' option like this:

options    = "uid=%(USER),nosuid,nodev,noexec,sec=ntlmssp,vers=1.0"

Oups !
My bad !!  :(


I didn't read everything carefully, I only focused on the code snippets...  :roll: :-?


Well, nothing to add for now.

Have fun everyone ! :wink:
