I work for a web development company that also manages the hosting of our customers websites.The hosting is shared and only on 3 servers. The webservers are Debian webservers where each customer has his own account to reach his own website files.
Normally I would log in to the server as this customer and add my ssh key to an authorized_keys file so that I can simply ssh into the account without having to lookup the password, this works perfectly fine.
The downside is I have to do this for every account over again, is there a way to add it to the server only once so that I can access all the accounts?
I tried putting the authorized_keys file in a .ssh folder in the root of the server but this doesn't seem to provide me access with any account. I have to admit my Linux knowledge is limited, so am wondering if this is even possible?
