After creating a "standard" user (with an admin user), the standard user gets this error when trying to connect via ssh with a remote host:

asdf@asdfasdf:~$ ssh remote_user_name@company_server
/bin/bash: line 0: exec: connect: not found
ssh_exchange_identification: Connection closed by remote host

After that, I have "upgrade" the standard user to make it administrator via visudo and with the graphical user admin tool.

Still the problem persists (now if I add "sudo " to the above line, it works).

Now I wonder: What are the permissions needed to connect via ssh with a remote host ?
