SSH
配置文件
用于 ssh、git。
~/.ssh/config
# server
Host myserver
HostName www.server.com
User lynn
IdentityFile ~/.ssh/id_rsa_xxx
# by proxy
Host server02
HostName 172.16.12.12
User lynn
ProxyJump myjump
# github
Host github.com
HostName github.com
User git
UseKeychain yes
AddKeysToAgent yes
IdentityFile ~/.ssh/id_rsa_xxx# Mac添加密钥到ssh-agent并存入钥匙串（避免重复输入密码）
ssh-add --apple-use-keychain ~/.ssh/id_rsa_xxx问题
No matching host key type found. Their offer: ssh-rsa
原因：openssh 觉得 ssh-rsa 加密方式不安全，直接从 8.8 开始默认不允许登陆。
长期方案
~/.ssh/config
Host myjump
Port 2022
HostName jumpserver.com
HostKeyAlgorithms +ssh-rsa
PubkeyAcceptedKeyTypes +ssh-rsa
User test临时方案
sftp -P 2022 -oHostKeyAlgorithms=+ssh-rsa xxx@jumpserver.com
