Python – Script8: Take Backup Configs of Multiple devices via SSH (Paramiko)

Step1: Configure file with all IP details of multiple devices

              nano myswitches

192.168.10.21 192.168.10.22 192.168.10.23 192.168.10.24

Step2: Configure file with for python script

              nano switchloopfileparamiko.py

import paramiko import time import getpass   # Get Username & Password username = raw_input(“Enter your username: “) password = getpass.getpass()   # Open file with list of switches f = open (‘myswitches’) for line in f:       ip_address = line.strip()     ssh_client = paramiko.SSHClient()     ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())     ssh_client.connect(hostname=ip_address,username=username,password=password)       print “Successful connection”, ip_address       remote_connection = ssh_client.invoke_shell()     print “Getting running-config of ” + ip_address       remote_connection.send(“enable\n”)     remote_connection.send(“cisco\n”)     remote_connection.send(“terminal length 0\n”)     remote_connection.send(“show run\n”)     remote_connection.send(“exit\n”)       time.sleep(20)     readoutput = remote_connection.recv(655350)     saveoutput = open(“Backup_Switch_” + ip_address, “w”)     print “Saving Configuration as Backup_Switch_” + ip_address + “\n”     saveoutput.write(readoutput)     saveoutput.write(“\n”)     saveoutput.close
