linux 使用密钥登录windows server 2016

背景：想要使用ssh从linux远程登录到windows server 2016，执行windows上的命令行

实践：

1，在windows server上安装openssh,选择合适的版本，64位系统选择：OpenSSH-Win64.zip 

设置成自动启动： Set-Service -Name sshd -StartupType ‘Automatic’

启动 sshd 服务
net start sshd

停止sshd 服务
net stop sshd

2，在windows上创建密钥

到openssh目录中执行：.\ssh-keygen 连续回车直到结束

生成文件到：

3.配置

找到C:\ProgramData\ssh\sshd_config文件，调整配置，加上下面配置

RSAAuthentication yes # 允许rsa

PubkeyAuthentication yes # 允许公钥登录

PermitRootLogin yes # 允许root登录

配置后整体文件如下：

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

# 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 __PROGRAMDATA__/ssh/ssh_host_rsa_key
#HostKey __PROGRAMDATA__/ssh/ssh_host_dsa_key
#HostKey __PROGRAMDATA__/ssh/ssh_host_ecdsa_key
#HostKey __PROGRAMDATA__/ssh/ssh_host_ed25519_key

# Ciphers and keying
#RekeyLimit default none

# Logging
#SyslogFacility AUTH
#LogLevel INFO

# Authentication:

#LoginGraceTime 2m

RSAAuthentication yes
PubkeyAuthentication yes
PermitRootLogin yes

#PermitRootLogin prohibit-password
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

#PubkeyAuthentication yes

# 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

# For this to work you will also need host keys in %programData%/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 yes
#PermitEmptyPasswords no

# GSSAPI options
#GSSAPIAuthentication no

#AllowAgentForwarding yes
#AllowTcpForwarding yes
#GatewayPorts no
#PermitTTY yes
#PrintMotd yes
#PrintLastLog yes
#TCPKeepAlive yes
#UseLogin no
#PermitUserEnvironment no
#ClientAliveInterval 0
#ClientAliveCountMax 3
#UseDNS no
#PidFile /var/run/sshd.pid
#MaxStartups 10:30:100
#PermitTunnel no
#ChrootDirectory none
#VersionAddendum none

# no default banner path
#Banner none

# override default of no subsystems
Subsystem    sftp    sftp-server.exe

# Example of overriding settings on a per-user basis
#Match User anoncvs
#    AllowTcpForwarding no
#    PermitTTY no
#    ForceCommand cvs server

Match Group administrators
       AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys

C:\ProgramData\ssh\如下：

4.配置linux机器端

想要从linux远程登录到windows，所以应该将windows上生成的私钥copy到linux的ssh目录

复制id_rsa内容，切换到root后复制到linux的/home/***/.ssh中创建id_rsa_jmp中

修改权限 chmod 600 id_rsa_jmp

5，测试从linux登录到windows

ssh -i ~/.ssh/id_rsa_jmp **@windows host ip

测试成功！
