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. 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?
For example, 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?
The error "Sever rejected the provided key" sucks after the fifth hour. I'm about to set up an ftp server and call it a day. What should I do to get multiple users to be able to connect to the site using RSA keys?
