Migrating Windows Server 2008 share permissions to synology NAS

access-control-listfile-permissionssynologywindows-server-2008

A customer has a Synology RS815+, using DSM 6.0.2-8451 Update 3. It has a btrfs volume. We want to migrate an existing CIFS share including timestamps and permissions. Timestamps are no problem, but the permissions do not copy over. Steps to reproduce:

Domain join NAS
Create share
Give domain users 'custom' rights, including 'change permissions' rights.
Use robocopy /COPYALL / TotalCmd with 'copy NTFS permissions' option / fastcopy with 'ACL' activated to copy files
Permissions not copied.

Best Answer

The permissions were actually copied correctly. However, under Server 2008, the Owner shows up separately under the security tab, on a Synology Share it doesn't. The permissions are still correct, however.

Try to either reset the account on the NAS in the domain or delete it. Sync the AD DCs. Make sure DNS on the box defined as one of the DCs.

Ssh – Unable to SSH to Synology NAS

To answer your question 1.) I had success logging into my SynoNAS via Telnet. You have to enable it first: Control Panel -> Terminal & SNMP -> Enable Telnet service.
After that you should be able to just telnet [nas_ip] into your NAS. It should even give you bash.

As of now, I wasn't able to repair ssh. It just somehow stopped letting me connect, without a single error message in /var/log/messages or /var/log/auth.log.

Update:
I was able to repair ssh by changing permissions to my user folder /volume1/homes/[user] to 0755. It might even work with stricter permissions. The command used was

chmod 0700 [user_folder]

I was made aware of this by the following post:
