Question

How to ssh directly to Remote Server, below is the details description.

Local machine ---> Jump1 ----> Jump2 ----> Remote Server

Answer 1

Set your ~/.ssh/config:

Host Jump1
  User jump1user
  Port 2222
Host Jump2
  ProxyCommand ssh -W %h:%p Jump1
  User jump2user
Host RemoveServer
  ProxyCommand ssh -W %h:%p Jump2

Host RemoveServer
  ProxyJump jump1user@Jump1,jump2user@Jump2
  User remoteUser
