# $OpenBSD: sshd_config,v 1.48 2002/02/19 02:50:59 deraadt Exp $
# This is the sshd server system-wide configuration file. See sshd(8)
# 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.
