# This is the sshd server system-wide configuration file.  See

# sshd_config(5) for more information.



# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin



# The strategy used for options in the default sshd_config shipped with

# OpenSSH is to specify options with their default value where

# possible, but leave them commented.  Uncommented options change a

# default value.



# Note that some of FreeBSD's defaults differ from OpenBSD's, and

# FreeBSD has a few additional options.
