Taking input from a file to paramiko

Question

I wrote a code to ssh to a server an execute a command, I now need to pass IPs from a file to ssh and run the same commands.

I used paramiko as an ssh client, in client.connect I gave hostname statically, I would like to pick one IP at a time from a text file and execute the same program.

import paramiko
import logging
import sys
logging.basicConfig(level=logging.INFO)
    def EsxCli():
        client = paramiko.SSHClient()
        client.set_missing_host_key_policy(paramiko.AutoAddPolicy) client.connect(hostname='192.168.110.41',port='22',username='root',password='VMware1!',look_for_keys=False)
        stdin,stdout,stderr = client.exec_command('/etc/init.d/vShield-Stateful-Firewall status')
        output_read = stdout.read()
        if 'vShield-Stateful-Firewall is running' in str(output_read):
        logging.info('\nService is already running!')
        sys.exit(1)
        elif 'vShield-Stateful-Firewall is not running' in str(output_read):
            logging.info('\nService is down, STARTING IT NOW')
            stdin, stdout, stderr = client.exec_command('/etc/init.d/vShield-Stateful-Firewall start')
            service_status = stdout.read()
            logging.info(str(service_status))
        else:
            logging.exception('SSH Timed OUT')
            sys.exit(1)
EsxCli()

The same code has to be executed for multiple hostnames. say 192.168.110.41 to 192.168.110.200

So what does your text file contain? List of IPs (192.168.110.41, 192.168.110.42, 192.168.110.43, ...) ? Or some kind of IP range (192.168.110.41-192.168.110.200)? — Martin Prikryl, Jan 09 '19 at 17:02
OK, that you question has nothing to do with Paramiko and is basically a duplicate to [How to read a file line-by-line into a list?](https://stackoverflow.com/q/3277503/850848) — Martin Prikryl, Jan 21 '19 at 13:14

I have been able to complete this. Converted the file into a python LIST.

ip = r'iplist.txt'
iplist=[line.strip() for line in open('iplist.txt')]
print(iplist)

Below is the script.
