-.It Pa /etc/ssh/sshd_config
-Contains configuration data for
-.Nm sshd .
-The file format and configuration options are described in
-.Xr sshd_config 5 .
-.It Pa /etc/ssh/ssh_host_key, /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
-These three files contain the private parts of the host keys.
-These files should only be owned by root, readable only by root, and not
-accessible to others.
-Note that
-.Nm
-does not start if this file is group/world-accessible.
-.It Pa /etc/ssh/ssh_host_key.pub, /etc/ssh/ssh_host_dsa_key.pub, /etc/ssh/ssh_host_rsa_key.pub
-These three files contain the public parts of the host keys.
-These files should be world-readable but writable only by
-root.
-Their contents should match the respective private parts.
-These files are not
-really used for anything; they are provided for the convenience of
-the user so their contents can be copied to known hosts files.
-These files are created using
-.Xr ssh-keygen 1 .
-.It Pa /etc/moduli
-Contains Diffie-Hellman groups used for the "Diffie-Hellman Group Exchange".
-The file format is described in
-.Xr moduli 5 .
-.It Pa /var/empty
-.Xr chroot 2
-directory used by
-.Nm
-during privilege separation in the pre-authentication phase.
-The directory should not contain any files and must be owned by root
-and not group or world-writable.
-.It Pa /var/run/sshd.pid
-Contains the process ID of the
-.Nm
-listening for connections (if there are several daemons running
-concurrently for different ports, this contains the process ID of the one
-started last).
-The content of this file is not sensitive; it can be world-readable.
-.It Pa ~/.ssh/authorized_keys
-Lists the public keys (RSA or DSA) that can be used to log into the user's account.
-This file must be readable by root (which may on some machines imply
-it being world-readable if the user's home directory resides on an NFS
-volume).
-It is recommended that it not be accessible by others.
-The format of this file is described above.
-Users will place the contents of their
-.Pa identity.pub ,
-.Pa id_dsa.pub
-and/or
-.Pa id_rsa.pub
-files into this file, as described in
-.Xr ssh-keygen 1 .
-.It Pa "/etc/ssh/ssh_known_hosts", "~/.ssh/known_hosts"
-These files are consulted when using rhosts with RSA host
-authentication or protocol version 2 hostbased authentication
-to check the public key of the host.
-The key must be listed in one of these files to be accepted.
-The client uses the same files
-to verify that it is connecting to the correct remote host.
-These files should be writable only by root/the owner.
-.Pa /etc/ssh/ssh_known_hosts
-should be world-readable, and
-.Pa ~/.ssh/known_hosts
-can, but need not be, world-readable.
