客观的
我想从我的 Windows 计算机（Windows 10）访问我的本地 Mac 计算机（版本：High Sierra 10.13.5）。目的是实现自动化，删除密码验证并添加 SSH 密钥访问。两台机器都使用同一个 Wi-Fi。
Mac 配置
这是我的 sshd_config 文件：
# $OpenBSD: sshd_config,v 1.101 2017/03/14 07:19:07 djm Exp $
# 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 override the
# default value.
#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::
#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_dsa_key
#HostKey /etc/ssh/ssh_host_ecdsa_key
#HostKey /etc/ssh/ssh_host_ed25519_key
# Ciphers and keying
#RekeyLimit default none
# Logging
#SyslogFacility AUTH
#LogLevel INFO
# Authentication:
#LoginGraceTime 2m
#PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10
#PubkeyAuthentication no
# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
# but this is overridden so installations will only check .ssh/authorized_keys
AuthorizedKeysFile .ssh/authorized_keys
#AuthorizedPrincipalsFile none
#AuthorizedKeysCommand none
#AuthorizedKeysCommandUser nobody
# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# HostbasedAuthentication
#IgnoreUserKnownHosts no
# Don't read the user's ~/.rhosts and ~/.shosts files
#IgnoreRhosts yes
# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication no
#PermitEmptyPasswords no
# Change to no to disable s/key passwords
ChallengeResponseAuthentication no
# Kerberos options
#KerberosAuthentication no
#KerberosOrLocalPasswd yes
#KerberosTicketCleanup yes
#KerberosGetAFSToken no
# GSSAPI options
#GSSAPIAuthentication no
#GSSAPICleanupCredentials yes
# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication. Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM no
#AllowAgentForwarding yes
#AllowTcpForwarding yes
#GatewayPorts no
#X11Forwarding no
#X11DisplayOffset 10
#X11UseLocalhost yes
#PermitTTY yes

以下是 Mac 上的 .ssh 文件夹：
User$ ls -a
. .. id_rsa id_rsa.pub known_hosts
Windows 配置
这是我的 Windows 计算机上的 .ssh 文件夹：
Répertoire de C:\Users\myName\.ssh
28/06/2018 20:13 <DIR> .
28/06/2018 20:13 <DIR> ..
28/06/2018 20:28 1 679 id_rsa
28/06/2018 20:28 397 id_rsa.pub
28/06/2018 21:17 1 608 known_hosts
按键
我已经在 Windows 和 Mac 电脑上生成了 SSH 密钥来生成文件夹，然后我将公钥“.pub”从 Windows 复制到 Mac/.ssh/id_rsa.pub
尝试的步骤
我在 Windows 中运行了这个：
C:\Users\myName>ssh [email protected] -vvv
输出结果如下：

我对于我错过的任何步骤都有点迷失。
答案1
由于您是从 Windows 访问 Mac，因此您需要 Windows 系统上的私钥和 Mac 上的公钥。公钥放在您 ssh 连接的主机（在本例中为 Mac）上名为 authorized_keys 的文件中。它位于：
~/.ssh/authorized_keys
该文件包含您将要连接的客户端的公钥。
确保使用 chmod go-rwx authorized_keys 设置文件权限。如果该文件可由所有者以外的人读取，我相信 ssh 将不会处理该文件。
