Python Code to Ping Servers

This is sort of a follow up from my tip last week - Cut Command a couple of examples.

Below is the code, the first section is setting the variables to read the config file, stored in certain directories, and also write out to a log file.

The code is very simple to do the ping and will write out if it responds or if it's down.

Very small easy script if you do have a long list of servers that you need to check.

import os							
import subprocess				
import sys							

filename = sys.argv[0]												myping = "ping -n 2 "													
logdir = os.getenv("logs")				
logfile = 'dns_ping.log'										
logfilename=os.path.join(logdir, logfile)											
confdir = os.getenv("my_config")													
conffile = ('dns1_list.txt')									
conffilename=os.path.join(confdir, conffile)									
f = open(logfilename, "w")											
for server in open(conffilename):									
  ret = subprocess.call(myping + server, shell=True,stdout=f,stderr=subprocess.STDOUT)	
  if ret == 0:						
    f.write (server.strip() + " is alive" + "\n")					
  else: 
    f.write (server.strip() + " did not respond" + "\n")
	 
print ("\n\tYou can see the results in the logfile : "+ logfilename);
