ssh 两次跳转，通过跳板机直接登录设备

在本机的~/.ssh/config文件中添加下面内容:

#跳板机ip
Host env-1
  HostName 192.xx.x.x
  User user
 
#设备ip
Host nv-5
  HostName 10.xxx.x.x
  User root
  ProxyJump env-1
 

将本机~/.ssh/id_rsa.pub中的公钥拷贝到user@192.xx.x.xx的~/.ssh/authorized_keys中;

将本机~/.ssh/id_rsa.pub中的公钥拷贝到root@10.xx.x.x的~/.ssh/authorized_keys中;

在本地终端中执行ssh env-1检查到192.xx.xx.xx是否已经免密;

在本地终端中执行ssh nv-5检查到10.xxx.x.x是否已经免密;
