问题现象
ssh user1@192.168.1X.XX
Unable to negotiate with 192.168.1X.XX port 22: no matching key exchange method found. Their offer: gss-group1-sha1-toWM5Slw5Ew8Mqkay+al2g==,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
OpenSSH in Linux解决方法
方案一：ssh -o选项指定KexAlgorithms和HostKeyAlgorithms
ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 -o HostKeyAlgorithms=+ssh-rsa user1@192.168.1X.XX注： -o 'option' Process the option as if it was read from a configuration file.
方案二：配置/etc/ssh/ssh_config客户端配置文件
KexAlgorithms=+diffie-hellman-group1-sha1
HostKeyAlgorithms=+ssh-rsa
MACs=+hmac-sha1OpenSSH in Windows解决方法
上面的解决方法，方案一在Linux和Windows上都OK，但是方案二针对的是Linux下的，很简单~~
那么Windows下安装的OpenSSH呢？存在ssh_config吗？
我们先看看Windows上的OpenSSH安装目录在哪？有没有ssh_config。
C:\Windows\System32\OpenSSH\下有sshd_config_default，却没有ssh_config文件；手动增加，配置后也没有生效。好吧~~去Microsoft官网查查吧！
OpenSSH Server configuration for Windows | Microsoft LearnLearn about the Windows-specific configuration options for OpenSSH Server on Windows Server and Windows.
https://learn.microsoft.com/zh-cn/windows-server/administration/OpenSSH/openssh-server-configuration通过上面链接查找，刚好查到，ssh客户端配置文件：%userprofile%\.ssh\config
那么，我们看看%userprofile%\.ssh\目录下都有啥：
dir %userprofile%\.ssh\
Volume in drive C is Windows
Volume Serial Number is D46B-XXXXDirectory of C:\Users\user1\.ssh
2025/02/14 10:33 <DIR> .
2025/02/14 09:55 <DIR> ..
2025/02/14 09:55 225 known_hosts
2 File(s) 311 bytes
2 Dir(s) 15,802,699,776 bytes free
没有config文件，创建一个即可：
echo KexAlgorithms=+diffie-hellman-group1-sha1 >> %userprofile%\.ssh\config echo HostKeyAlgorithms=+ssh-rsa >> %userprofile%\.ssh\config echo MACs=+hmac-sha1 >> %userprofile%\.ssh\configC:\Users\xiao>ssh user1@192.168.XX.210
