Small python script template to get current system to lock on to a particular load balance server; must be customized for target hosts

lockon

#!/usr/bin/python

import os
import sys

if len(sys.argv) < 2:
  print 'Usage: load [a|b|c]'
  raise SystemExit()

if sys.argv[1] == 'a':
  ip = '203.0.113.1'
if sys.argv[1] == 'b':
  ip = '203.0.113.2'
if sys.argv[1] == 'c':
  ip = '203.0.113.3'

if not ip:
  print 'Param must be: a|b|c'
  raise SystemExit()

host = 'www.example.com'
cmd = 'sed -i "s|.*'  +host+  '|'  +ip+  ' '  +host+  '|g"'
target = '/etc/hosts'

## Example command, expanded out ##
# sed -i "s|.*www.example.com|203.0.113.1 www.example.com|g" /etc/hosts

os.system(cmd + ' ' + target)

• I currently think that curl is somewhat sweeter than using this to try to get a browser to hit certain load balance servers.
