Samba server

By default, directory created on shares have permissions 777. To change this, we disable CIFS extensions [2]: 

unix extensions=no

To restart samba on the synology: 

/usr/syno/etc/rc.d/S80samba.sh restart

Old solution — Another solution is to enforce permissions on the server side. For this, edit /usr/syno/etc/smb.conf, and add to [global] section [3]: 

	create mask=644
	security mask=644
	directory mask=755
	directory security mask=755
	force create mode=644
	force security mode=644
	force directory mode=755
	force directory security mode=755

Note this might interfere with synology defaults [4]. We don't apply this configuration because we use unison to backup the shares on a remote server, and the easiest solution is to sync permissions and uses 777/766 permission settings.

How-To

Enable SSH

  • Enable SSH service
  • To have root access, log in as user root, and use same password as admin account.

Mount NAS samba share on client

Client must explicitly specify charset utf8 in the mount line: 

mount -t cifs //mnemosyne/photos /smb/mnemosyne/photos -o noperm,iocharset=utf8

If you get the error mount error(13): Permission denied, you need to add the option sec: 

mount -t cifs //mnemosyne/photos /smb/mnemosyne/photos -o noperm,iocharset=utf8,sec=ntlm

Enable NFS

(See HOW-TO page here)

  • Enabled NFS service
  • Edited NFS privilege for share volume1/backup, allow rw, for client minimoy
  • Then from NFS client, tried
    • sudo mkdir -p /net/mnemosyne/backup
sudo mount mnemosyne:/volume1/backup /net/mnemosyne/backup
# mount.nfs: access denied by server while mounting mnemosyne:/volume1/backup
  • Looking into NAS file /var/log/messages (need to ssh as root on the NAS), there is the line:
    • ... refused mount request from HOST00245402988d.HELL for /volume1/backup (/): no export entry
  • So it seems that the connection is refused because the DNS name of the NFS client does not match the export line in file /etc/exports
    • /volume1/backup minimoy.HELL(rw,no_wdelay,no_root_squash,insecure_locks,anonuid=0,anongid=0)


Found a working recipe on this page:

  • Content of file /etc/exports
    • /volume1/backup 172.19.100.102(rw,no_wdelay,no_root_squash,insecure_locks,anonuid=0,anongid=0)
  • Touched file /var/lib/nfs/rmtab (because non-existent) :
    • touch /var/lib/nfs/rmtab
cd /
/usr/sbin/exportfs -a            # Update list of exported filesystem
  • On NFS client, mount the NFS share with:
    • sudo mount mnemosyne:/volume1/backup /net/mnemosyne/backup


Open issues:

  • How to make it to work using hostname instead of IP addess?
    Additional problem is that at each boot DNS Relay table on the ADSL router is reset to 'HOSTxxxxxxxxxxx' for wired interface on the NFS client, hence making it not recognizable for the NFS server.
  • How to deal with Access Control? I want root to be mapped to nobody, and write access only allowed for one user (which requires password to login)?
    This can be done with the following export line:
/volume1/backup minimoy.HELL(rw,no_wdelay,root_squash,insecure_locks)
