sshd: Could not load host key

Question

Running /usr/sbin/sshd produces the following results:

Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_dsa_key
Could not load host key: /etc/ssh/ssh_host_ecdsa_key
Could not load host key: /etc/ssh/ssh_host_ed25519_key
Missing privilege separation directory: /var/run/sshd

I checked in /etc/ssh and all 4 host keys (and their .pub files) seem to be available, although /var/run/sshd is missing.

What can I do to let it load the host keys?

Answer 1

Run the command with sudo:

sudo /usr/sbin/sshd

If you still get the privilege separation directory error:

sudo mkdir /var/run/sshd && sudo chmod -R 755 /var/run/sshd
