ssh-usage

连接

• -i指定密钥

• -o加option

  -o TCPKeepAlive=yes        //长连接
  -o ServerAliveInterval=30  //

端口转发

ssh -L local_port:localhost:remote_port -N -T user@server_address -p   server_ssh_port
如:
ssh -L 9999:localhost:8888 -N -T user_test@111.111.111.111 -p 22
将发送到本地端口9999的请求数据转发到111.111.111.111转发到8888端口

配置

1. config文件配置: ~/.ssh/config

   #配置
   Host gitee.com
       HostName gitee.com
       IdentityFile xxx/xxx/_id_rsa
       PreferredAuthentications publickey
       User xxx
       TCPKeepAlive=yes
       ServerAliveInterval 60

2. 配置服务端

• 件位置,全局位置: /etc/ssh/sshd_config
• 文件位置,termux: $PREFIX/etc/ssh/sshd_config
• 配置:
  • PasswordAuthentication (密码验证) yes/no
  • 启用密钥验证
    • RSAAuthentication (rsa秘钥) yes/no
    • PubkeyAuthentication (公钥) yes/no

3. 认证秘钥,将公钥写入该文件(authorized_keys),就可使用该公钥登陆
   • 位置: ~/.authorized_keys

工具

• windows terminal

  连接远程机器使用 ssh 配置
  {
      "guid": "{xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx}",
      "hidden": false,
      "name": "xxxxxxx",
   //密钥放在本地，-i 指定密钥位置
      "commandline": "ssh -i xxxxxxx_id_rsa user@host -p xxxxxxxx  -o TCPKeepAlive=yes -o   ServerAliveInterval=30",
   "startingDirectory": "/home/xxxxxxx",
   "icon" : "ms-appx:///ProfileIcons/{9acb9455-ca41-5af7-950f-6bca1bc9722f}.png"
