Readynas 314 and iDrive

I don't use iDrive, but I know enough Linux I can help with the instructions given.

In order to access the NAS Linux command line, you need to enable SSH on the NAS "Settings" tab.  Then, open a Windows command prompt and type ssh root@<NAS_IP_Address> (using the real IP address.  The password is the same as the NAS admin password.

Now you need to edit a file.  The built-in editor is a big pain to use, but you can use it with vi /etc/passwd.  But you are better off installing another editor first -- I like nano.  So, do an apt-get install nano (which will take a bit), then nano /etc/passwd.

But then comes a problem, the file it's telling you to change does not contain the line it's telling you to change.  It has this:

admin:x:98:98::/home/admin:/bin/bash, and I don't think you should be changing that from bash to sh.  The change it's asking you to make would be if admin wasn't allowed login at all.  So, you're going to have to get somebody who knows iDrive to tell you what else might be causing this. 

One possibility is that iDrive is trying to use sudo to elevate admin's rights to root access, but the ReadyNAS does not include sudo, it expects you to log in a user root in ssh.  When logged in SSH as root, you can try apt-get install sudo.  This is as much a guess as anything else, so it may or may not solve your problem.  But I don't think it will hurt, either.
