Collecting User IP!

A sample BASH CGI script for collecting IPs of your colleagues in your network.

Prerequisites
1) apache/cgi configuration
2) a Mysql installation

Then create script “getip.sh” under “/var/www/cgi-bin/” ( set location of cgi-bin directory as per the apache configuration)

#!/bin/bash
#Getting IP address CGI-BASH-script

#MySQL settings

# MHOME= ( location of mysql binary)
MHOME=/usr/local/mysql/bin
HOST=127.0.0.1
USER=root
PASS=”"
DB=mydb

OWNER=$(echo “$QUERY_STRING” |awk -F “=” ‘{print $NF}’)
IP=$REMOTE_ADDR
#QUERY_STRING = Query information that follows the ? in the URL that referenced this script.
#REMOTE_ADDR = IP address of the remote host making the request

#HTML Output
echo “Content-type: text/html”
echo “”
echo “YOUR IP

I am collecting the IPs

”;
 echo “IP: $IP
”
echo “You Are IP is : $OWNER
”
 
$MHOME/mysql -u$USER -h$HOST –password=$PASS -e “INSERT INTO mydb.ips(rdate,ip,owner) VALUES(NOW(),’$IP’,'$OWNER’)” $DB
 
echo “

”;

Then

Create MySql Database for storing the data.

logon to mysql

mysql -u root -p password

create database and table

create database mydb

use mydb

create table mydb.ips ( rdate DATE, ip VARCHAR(20) NOT NULL PRIMARY KEY, owner VARCHAR(25));

exit

Suppose the IP of the box where you are running the cgi is “172.22.22.188″ (your local ip).

Now construct the urls for your colleagues this way:

http://172.22.22.188/cgi-bin/getip.sh?owner=alexm
http://172.22.22.188/cgi-bin/getip.sh?owner=nsarma
…
…

And send them the individual urls in mail with a request to click the url (just to help you collecting the ips in the mysql table)

Once they click, your database table will be automatically populated with datas like this:

mysql> select * from mydb.ips;
+————+—————+

———+
| rdate | ip | owner |
+————+—————+———+
| 2007-01-02 | 172.22.22.111 | alexm |
| 2007-01-03 | 172.22.22.92 | nsarma |
+————+—————+———+
2 rows in set (0.00 sec)

Finished.
