7 # This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
9 # The strategy used for options in the default sshd_config shipped with
10 # OpenSSH is to specify options with their default value where
11 # possible, but leave them commented. Uncommented options change a
14 # Note that some of DragonFly's defaults differ from OpenBSD's, and
15 # DragonFly has a few additional options.
