5# sshd_config(5) for more information.

7# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
8
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 override the
12# default value.
13
14# Note that some of FreeBSD's defaults differ from OpenBSD's, and
15# FreeBSD has a few additional options.
