Does anyone know why does this happen, what’s wrong with my standard
user and how to fix it?
There is nothing wrong; you are attempting to run sshd
(SSH daemon) as a non-privileged user.
For example, I am on Mac OS X 10.9.5 (Mavericks) and get the same exact “error” when running /usr/sbin/sshd -t
:
Could not load host key: /etc/ssh_host_rsa_key
Could not load host key: /etc/ssh_host_dsa_key
Which is to be expected since sshd
is the SSH daemon—note the d
after ssh
—that would run as a SSH server on the system listening and waiting for remote SSH login requests. So it would always need root/sudo
permissions to work.
So this is not an “error” but rather expected behavior when attempting to run a system daemon like sshd
as a non-privileged user.
Perhaps you are trying to run ssh -t
? As the man page for the ssh
-t
option explains:
Force pseudo-tty allocation. This can be used to execute arbitrary
screen-based programs on a remote machine, which can be very useful,
e.g. when implementing menu services. Multiple -t options force tty
allocation, even if ssh has no local tty.
Which basically allows you to run a command remotely from your current terminal and have the output displayed locally as if it ran on your local machine. So—as this page explains—if you wanted to run ls
on a remote machine without actually fully logging in you could run this command:
ssh -t [username]@[hostname] ls
The output of ls
would show up on your screen and the ssh
connection would close immediately after that command completed.
