Via linux command line, I'm trying to connect (actually stay connected) to a remote server with this command: ssh -l <username> <remote server IP> It connects, but right away it closes the connection. "Connection to <remote server IP> closed." <username> is a user account on both the local and the remote server. <username> is not root. I've logged in remotely to this server with Putty on a Windows computer. So, ssh does work to login to this remote host through Putty and with the same <username>. Does anyone know the issue here, I've searched around, but couldn't find a solution that works. Thanks.
