# $OpenBSD: sshd_config,v 1.59 2002/09/25 11:17:16 markus Exp $
# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin
# 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.
#Port 22 SSH 默認(rèn)的堅(jiān)挺端口
#Protocol 2,1 選擇SSH的版本
#ListenAddress 0.0.0.0 監(jiān)聽的IP地址

# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key SSH VERSION 1 使用的密鑰
# HostKeys for protocol version 2
#HostKey /etc/ssh/ssh_host_rsa_key SSH VERSION 2 使用的RSA私鑰
#HostKey /etc/ssh/ssh_host_dsa_key SSH VAESION 2 使用的 DSA私鑰

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#RhostsRSAAuthentication no 不使用針對(duì) VERSION 1 使用RHOSTS 文件在/ETC/HOSTS.EQUIV 配合RAS進(jìn)行認(rèn)證 不建議使用
