3# This is the sshd server system-wide configuration file.  See
4# sshd_config(5) for more information.

6# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
7
8# The strategy used for options in the default sshd_config shipped with
9# OpenSSH is to specify options with their default value where
10# possible, but leave them commented.  Uncommented options override the
11# default value.
12
13# Note that some of FreeBSD's defaults differ from OpenBSD's, and
14# FreeBSD has a few additional options.
