Restoring SSH Access

One of the most powerful features of the ReadyNAS product line is the ability to enable Secure SHell (SSH) access. Via SSH, it is possible to both install additional software as well as gain secure remote access to the ReadyNAS unit.

Once enabled, many users prefer to customise their SSH access also, particularly to increase security vs the default settings by, for instance, limiting root access or requiring public key authentication be used. To achieve this it is necessary to edit the file "/etc/ssh/sshd_config" file.

This however can be the source of major issues - edit the sshd_config file incorrectly and it is possible to prevent SSH access working correctly. But without SSH access there is no way to fix the error as a firmware reinstall will not will not revert the sshd_config file back to the default settings. And it is a very easy mistake to make...

Fortunately there is a way to restore the file to its default settings by following these steps:

How to Direct Connect to your ReadyNAS

When encountering a problem with a ReadyNAS device, it is often useful during the process of diagnosing that problem to eliminate the network to which the ReadyNAS is connected to determine if the issue is truly with the ReadyNAS, or due to the network to which it is connected.

Any ReadyNAS device can be connected directly to a client via a standard ethernet cable - there is no requirement for a cross-over cable as the ReadyNAS ethernet ports are autosensing. Therefore, to make the direct connection work, it is simply a matter of ensuring the client is configured with an appropriate IP address and subnet mask.

How to Migrate to User Security Mode

With newer OS'es like Windows 7 and OSX Snow Leopard, the "Share" security mode featured on some older ReadyNAS devices like the NV+ is unfortunately no longer supported. The solution to the problems this causes is to migrate the ReadyNAS to "User" security mode. In "User" mode, individual user accounts are created on the NAS for each person that will access it. That user account is then granted appropriate access to shares, rather than the shares themselves being password protected. To migrate to "User" mode, 3 major steps are required:
  1. Change Mode
  2. Create a User for you to access the NAS
  3. Fix permissions so that new user account has full access to the data, as before.
Afterwards you may wish to take an additional step 4) to create other user accounts and give them permissions that may be the same or different from your own user account. These are the accounts your friends, colleagues, family would use

How to Setup ReadyNAS Permissions

There have been many questions on the ReadyNAS forum regarding how to setup file sharing permissions when running a NAS with User security mode.

I have written a short overview, below, of the key share access & permissions settings available in Frontview when setting up a share & what they do, the misunderstanding of which is commonly the reason users have permission related issues.

All of the examples posted relate to CIFS access, but the settings apply equally to AFP and FTP access.

This information was originally posted here in response to one of the many such queries on the ReadyNAS forum.
