I am trying to nested SSH using Paramiko where I will connect to Server X from my local machine and from there I will connect to Server Y. Here to connect to Server X I am using username, password authentication and to connect to Server Y using username and RSA key. The thing is that the RSA key is hosted in System X which is used to connect Server Y. I was able to run the script successfully if I hosted the keyfile in my local PC and gave the local pc directory path to Paramiko SSH client. But I want to read key file from Server X directly. How can I do that please help me.
Server X key file = "/home/test/keys/id_rsa"
import time
import paramiko,io
import csv
import sys
import subprocess
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('X',22, username='subhash', password='mit@12345')
vmtransport = ssh.get_transport()
dest_addr = ('Y', 22)
local_addr = ('X', 22)
vmchannel = vmtransport.open_channel("direct-tcpip", dest_addr, local_addr)
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
remote_file = paramiko.RSAKey.from_private_key_file('C:/Users/test/Documents/hindi/id_rsa')
client.connect('Y', username='root',pkey=remote_file,sock=vmchannel)
client_stdin ,client_stdout, client_stderr = client.exec_command("pwd")
