rsa

Pardon my noobness, but I just got started with VPS (linux) hosting; setting up passwordless ssh for multiple users has proved to be kind of a pain.

Currently I'm the single user of this ubuntu 10.04 LTS VPS (linode.com). I was able to establish a single rsa passkey under my home/user/.ssh/authorized_keys location. Fine. PuTTy works as expected, and Filezilla (sftp) links up as required.

I've been working on a single site that this user owns, and thats not been a problem.

Now, I want to set up some other sites, and I've chosen Webmin with the VirtualMin plugin to make this work.

I made another user (or, rather, virtualmin did), but I've been unable to get FileZilla to link up to this new user.

Could anyone with experience here explain what the setup is supposed to look like?

IE - can I use a single rsa key pair for all accounts (if, for example, I give ownership of files to the original user?). Or is it standard practice to create a separate key pair for each user, and establish a separate putty/filezilla login for each?

I've spent enough time dinking around with this to be frustrated. "Sever rejected the provided key" error sucks after the fifth hour. I'm about to set up an ftp server and call it a day.

Any thoughts would be most welcome -

So far I've created a separate SSH key for each server I need to login to (for each purpose, to be more accurate). I did it out of a sense of security, just like different passwords to different sites. Does having multiple SSH keys actually improve security? All of them are used from the same machine… >>> More
