2. Monitor upload traffic using iptables

We can monitor the upload or download traffic for a host by adding iptables rules to the gateway, here are the steps:

2. To add a iptables rule:
   

   /sbin/iptables-i input-s 10.0.5.110

4. Create a database for storage: just one column,

6. Mysql> desc proxy;+-------+----------+------+-----+---------+-------+| Field | Type | Null | Key | Default | Extra |+-------+----------+------+-----+---------+-------+| IP | char (20) |     YES | |       NULL | |+-------+----------+------+-----+---------+-------+1 row in Set (0.00 sec)

8. Use Python to get traffic and make judgments:

9. #!/usr/bin/env python# -*- coding: utf-8 -*-import datetimeimport  Subprocessimport mysqldbimport smtplibfrom email.mime.text import mimetextimport  sysreload (SYS) sys.setdefaultencoding (' Utf-8 ') def get_traffic ():     j =  subprocess. Popen ("/sbin/iptables -n -v -x -l input|grep all|grep 10.0.5",  shell= True, stderr=subprocess. Pipe, stdout=subprocess. PIPE)     u = j.communicate ()     n = u[0].split (' \ n ')     return ndef html_construct ():    con =  MySQLdb.connect (host= ' localhost ', user= ' user ', passwd= ' passwd ', db= ' traffic_monitor ', charset= ' UTF8 ')      cur = con.cursor ()         html =  ""     html_head =  "" "     

11. Create Crontab
