Using a list of switch IP addresses, prompt for username and password and capture troubleshooting information for each switch:

import paramiko
import time
import getpass

username = raw_input(‘Enter your username: ‘)
password = getpass.getpass()

f = open (‘myswitches.txt’)

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 ‘Collecting troubeshooting log file of ‘ + ip_address

remote_connection.send(‘show clock\n’)
remote_connection.send(‘enable\n’)
remote_connection.send(‘terminal more disable\n’)
remote_connection.send(‘show run\n’)
remote_connection.send(‘terminal more enable\n’)

time.sleep(20)
readoutput = remote_connection.recv(655350)
saveoutput = open(‘Log file of ‘ + ip_address, ‘w’)

print ‘Saving to file called Log file of ‘ + ip_address + ‘\n’

saveoutput.write(readoutput)
saveoutput.write(‘\n’)
saveoutput.close

ssh_client.close()

Shell output..

$ python sshclient.py

Enter your username: rwa
