I'm trying to mount shares from our OSX server (10.11.5) onto my linux client (Ubuntu 15.10) after an upgrade to the server took place. Prior to the upgrade I was able to mount these directories without a problem using fstab entries like this:
//Server/Share /mnt/server/share cifs user=<user>,nounix,noauto,rw,uid=<user>,gid=<user> 0 0
However, after the upgrade I get the follow messages:
mount error(11): Resource temporarily unavailable
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
I also cannot mount the shares from Nautilus. Other Mac clients ARE able to mount the shares. The linux client is able to mount SMB shares from other Ubuntu servers.
Running smbclient
gives the following:
ntlmssp_handle_neg_flags: Got challenge flags[0x22810205] - possible downgrade
detected! missing_flags[0x00080000] - NT code 0x80090302
NTLMSSP_NEGOTIATE_EXTENDED_SESSIONSECURITY
SPNEGO(ntlmssp) login failed: NT code 0x80090302
session setup failed: NT code 0x80090302
Which suggests issues with ntlmssp
authentication. I have tried various sec=
additions to fstab but to no avail.
The OSX sudo serveradmin settings smb
output is as follows.
smb:ntlmv2 = no
smb:ntlmAuth = yes
smb:ServerDescription = "<REMOVED>"
smb:ntlmv2 auth = no
smb:wins server:_array_index:0 = _empty_dictionary
smb:spnego = no
smb:DOSCodePage = "437"
smb:NetBIOSName = "<REMOVED>"
smb:VirtualAdminShares = no
smb:logging = yes
smb:ntlm auth = yes
smb:AllowGuestAccess = no
smb:ntlmv2Auth = no
smb:LocalKerberosRealm = "<REMOVED>"
I have very little access to the OSX server and do not know the details of the upgrade (imperfect world I know). I am not officially in a position to make changes to the server directly but can request specific things be done.
Mounting in this direction (Ubuntu client, OSX server) appears uncommon and so I would appreciate any help, advice or even thoughts people might be willing to share.
