We have a sort of odd scenario where our clients are given cpanel accounts without ftp access (we lease websites to them and they only need to use cpanel to administer their email accounts), but need to give ftp access to ourselves for maintenance .... Is there a way to implement a master ftp account that can access any cpanel accounts that are setup within whm?

The end goals we are trying to achieve is that the client cannot access via ftp, but we can, preferably with a single logon / password.

Anyone have any thoughts or ideas? Any feedback appreciated!

Ahhhh, it looks like the whm root password used with the user's user name does the trick... I tried it previously with root as logon and root password to no avail...

A single user/pass for all ftp accounts wouldnt be a good idea because you would have to chown all the files after you uploaded them, every time. Plus of course its a security issue. What I would recommend doing is using the feature manager to disable all the extras that you dont want them to have access to, then disable the ftp port on your firewall except to your staff ip's. If your not on static ip's, then do it with dyndns.

I too agree with Macscr, Its not a good idea to user FTP using root passwd.

Yes, I too agree with Macscr. It will be a security threat using ftp using root password.
Have to disable the ftp port on firewall.
