[SOLVED] Advance ssh config file

Advance ssh config file

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

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

From local machine there is no direct access to Remote Server and Jump2 is disable Remote Server can only be accessed from Jump2

There is no sshkegen to remote server we have to give the paswword manually.

from Local Machine we access the Jump1 with ip and port 2222 then from Jump 1 we access the Jump2 with host name default port 22.

With ssh/config file we were able to access the jump2 server without any problem. But my requirement is to directly access the remote server.

is there any possible way I don't mind entering the password for remote server.

 ssh -vvv root@ip address
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013

My Config file

Host jump1
    Hostname ip.109
    Port 2222
    User avdy

Host jump2
    Hostname ip.138
    Port 22
    ProxyCommand ssh -W %h:%p jump1
    User avdy

Host remote-server
    Hostname ip.8
    Port 22
    ProxyCommand ssh -W %h:%p jump2
    User root

Solution

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
  User remoteUser

Or with new OpenSSH 7.3:

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

Then you can connect simply using ssh RemoteServer
