Centos – Mount issues with Samba under non-root user

centosdebianlinuxsamba

Maybe someone can shed some light here as I'm confused.

I have this setup:

Server 1 (CentOS File Server)

Shared directory /file/to/www/share (owned by web-user:web-user)
Samba user "web-user" added

Server 2 (Debian Web Server)

Mounted //[server]/[share] to /mnt/www_share
Server has local user "web-user:web-user"

Now, (as root) I can access the share and Read/Write/Execute.

Though, no other users can Write (only Read/Execute).

I've tried setting the directories to 777, setting the umask in Samba to 000. I cannot mount to the share as non-root.

Any ideas?

Thanks

Unlike NFS (which, BTW, should have been your choice for Linux to Linux mounting), SMB doesn't automatically share user authorizations across the protocol - at least not without a complicated "Active Directory" setup.

What you probably want to do (other than change to a protocol that does share some user details, such as NFS), is to mount the directory using the required user permissions, using the uid and gid options of the mount command or fstab file.

Use man fstab, man mount (the smbfs section) and man smbmount for more details.

You might also be interested in investigating the fmask and dmask options.

“Error mounting location: volume doesn't implement mount” apparently translates to “I need D-Bus but it isn't available”. (Thanks to venturax's guru colleague for this information.) Within an SSH session, I can use gvfs-mount provided that dbus-daemon is launched first and the environment variable DBUS_SESSION_BUS_ADDRESS is set.

export $(dbus-launch)
gvfs-mount smb://workgroupname\;username@hostname/sharename
# Type password
ls ~/.gvfs/'sharename on hostname'

gvfs-mount and other GVFS utilities must all talk to the same D-Bus session. Hence, if you use multiple SSH sessions or otherwise use mounts across login sessions, you must:

start D-Bus the first time it is needed, at the latest;
take care not to let D-Bus end with the session, as long as there are mounted GVFS filesystems;
reuse the existing D-Bus session at login time if there is one.

See Reuse D-Bus sessions across login sessions for that.
