# macOS ssh to win10 with ssh key
因為看好多篇結果一樣沒解決問題，所以寫一篇完整的出來希望能幫到後人

win10安裝openSSH步驟省略，安裝應該沒什麼坑

`C:\ProgramData\ssh\sshd_config`

//不要註解下面三行
PubkeyAuthentication yes
AuthorizedKeysFile	.ssh/authorized_keys
PasswordAuthentication no
//註解下面兩行
#Match Group administrators
#       AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys

在macOS 透過 `ssh-keygen` 生成 key (都用預設值，不用password)
`id_rsa`(私鑰,存於Mac),`id_rsa.pub`(公鑰,傳至Server)
並且透過`key-add -K ~/.ssh/id_rsa`加入macOS系統

將`id_rsa.pub`內容，複製到Server(以win10為例)。
在`C:\Users\{username}\.ssh`底下新增`authorized_keys`，並將`id_rsa.pub`內容貼上

完成後重啟

net stop sshd
net start sshd

or

Restart-Service sshd

## VSCode RemoteSSH
`config`

Host {設定檔名稱}
	HostName {serverIP}
	User {UserID}
	Port 22
	IdentityFile /Users/{MacOSUserID}/.ssh/id_rsa

UserID(cmd輸入)

$env:USERNAME

serverIP(cmd輸入)

ipconfig | select-string  ('(\s)+IPv4.+\s(?<IP>(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}))(\s)*') -AllMatches | %{ $_.Matches } | % { $_.Groups["IP"]} | %{ $_.Value }
