You will need “rar” to extract it, its in rar extension. Here is HowTo install and extract rar files

cd DarkSQLi

./darksqli.py -u <url> –findcol      ( It will find out the column length )

./darksqli.py -u <url> –info            ( MySQL server configuration )

./darksqli.py -h           ( To view complete help, different options )

There are many option to test, it supports SSL too.

Here, i’ll tell you how to install on linux.

If you are using RHEL/CentOS, you can simple install it through “yum”

rpm -Uvh http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

yum install rar

If you are using LinuxMint, Ubuntu, UbuntuME, run the following command;

apt-get install rar

or

aptitude install rar

You can try different switches, try ;

rar  e      ” Extract the data from .rar archive”

rar –help

Lets see How to install it.

Download from here

Install the following requirements:

• Python 2.6
• Pybluez
• PySQLite

Installation

1. tar -zxvf haraldscan-0.3.tar.gz
2. cd haraldscan-0.3
3. python haraldscan -b

How to use it

python haraldscan

Or you can use different switches, e.g;

-w   – Writes the devices table to a file.

-h – Brings up the help menu.

Here is the tip, it will  sort out the files from top to bottom.

find /var -mount -ls -xdev | /usr/bin/sort -nr +6 | more

ls -al | grep “^d”

Let me show you my “/var/log/secure” first, it was something like this;

May 11 13:23:54 proxy sshd[10855]: Illegal user administrator from 202.162.541.34
May 11 13:23:54 proxy sshd[10855]: Failed password for illegal user administrator from 202.162.541.34 port 34645 ssh2
May 16 10:43:04 proxy sshd[10857]: Illegal user samba from 116.11.72.234
May 16 10:43:04 proxy sshd[10857]: Failed password for illegal user samba from 116.11.72.234 port 54645 ssh2

For this damn attacks, i used two simple rules of iptables as follows;

iptables -A INPUT -i eth1 -p tcp –dport 22 -m state –state NEW -m recent –set –name SSH
iptables -A INPUT -i eth1 -p tcp –dport 22 -m state –state NEW -m recent –update –seconds 200 –hitcount 5 –name SSH -j DROP

Here let me describe the above command.
“eth1″ is the network interface to which ssh connections are made. In my case, i assigned Public IP to it. It can be change in your scenario.
“–seconds 200″ and “–hitcount 5″ means 5 connections allowed in 200 seconds.

The only bad thing is it will block you too, if you made wrong attempts like brute force.. lolz. For that thing, you can do add your IP to whitelist.

Hope it helps.
Any question? follow up in comments.

I will use the following hardware, you can use your own depends on your requirements.

Pentium III -1 GHz

512 MB Ram

20 GB Hard drive

3 Lan cards

Why we are using 3 lan cards?

We will use 2 Lan cards for two different ISPs, while 1 lan card for your LAN.

I will use the following scenario.

Interface =  eth0

Connected = LAN

IP = 10.0.0.1

Interface = eth1

Connected =  ISP-1

IP = 192.168.0.2

Gateway = 192.168.0.1

Interface = eth2

Connected = ISP-2

IP = 192.168.1.2

Gateway = 192.168.1.1

Step 1 : Setting up network interfaces.

system-config-network-tui

Please configure all interfaces as mentioned above with the above command one by one.

Step 2 : Turning on IP packet forwarding.

vi /etc/sysctl.conf

By default value of  “net.ipv4.ip_forward" is "= 0", change it to "= 1"

sysctl -p

Step 3 : In this step, we need to configure iptables by adding some rules, so that our Internet LAN can route packets to the Internet.

iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

iptables -t nat -A POSTROUTING -o eth2 -j MASQUERADE

iptables -A FORWARD -s 10.0.0.0/8 -j ACCEPT

iptables -A FORWARD -d 10.0.0.0/8 -j ACCEPT

iptables -A FORWARD -s ! 10.0.0.0/8 -j DROP

The above commands turn on masquerading in the NAT table by appending a POSTROUTING rule for all outgoign packets on the two Ethernet interfaces, eth1 and eth2. The next two lines accept forwarding of all packets to and from 10.0.0.0/8 network. The last line drops the packets that do not come from 10.0.0.0/8 network.

Step 4 : Save iptables rules permanent.

iptables-save > /etc/sysconfig/iptables

service network restart

service iptables restart

Here, i will give you extra tip if you are using Squid Transparent Proxy. You will need the following rules in iptables.

I will update it soon…

I will use the following scenario:

munin-server.example – 192.168.1.254        # Munin Server

station1.example.com – 192.168.1.1            # Munin client

station2.example.com – 192.168.1.2            # Munin client

You can add many clients as much you want. Here i added two clients. Here on more thing to notice, using hostname is not necessary. We are not required any DNS resolution, it is just for clarity to recognize your client easily.

Let start with Installation and configuration:

Server Side

Step 1 : First of all enable CentOS repository to install the latest packages of munin, presonally i preffered dag/rpmforge repository is the best resource for upload packages of CentOS and RHEL distrobution.

rpm -Uvh http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

yum install perl-Net-Server perl-Socket6 perl-Crypt-DES perl-Net-SNMP perl-Digest-HMAC perl-Digest-SHA1

yum install perl-rrdtool rrdtool perl-HTML-Template perl-DateManip munin

By default it will create the following directories,files.

Main Server main Configuration file :

/etc/munin/munin.conf

Munin cron file :

/usr/bin/munin-cron

Munin libraries :

/var/lib/munin

Munin logs :

/var/log/munin

Munin Document Root :

/var/www/munin

Step 2 : Changing default Munin Document Root Path :

mv /var/www/munin /var/www/html/munin

Step 3 : Adding clients/nodes to monitor them in /etc/munin/munin.conf :

vi /etc/munin/munin.conf

[station1.example.com]

address 192.168.1.1

use_node_name yes

[station2.example.com]

address 192.168.1.2

use_node_name yes

Step 4 : Setting up permissions :

groupadd munhttp

usermod -G munhttp munin

usermod -G munhttp apache

chown -v apache.munhttp /var/www/html/munin

Step 4 : Setting up cron to schedule the munin to update every 5 minutes :

crontab -e

*/5 * * * * /usr/bin/munin-cron –force-root

Step 5 : Restart Apache :

service httpd restart

Client Side

Here we go with installing the clients/nodes.

Step 1 : Installing the required packages :

yum install perl-Net-Server perl-Net-SNMP perl-Digest-HMAC perl-Digest-SHA1 munin-node

Step 2 : Editing /etc/munin/munin-node.conf for server ip address, you have to add it bottom of the file, below the line ” allow ^127.0.0.1$”

vi /etc/munin/munin-node.conf

allow ^192.168.1.254$

Step 3 : The following command will scan the system for available services and will auto configure it. e.g Sendmail, mysql.

munin-node-configure

Step 4 : Start Munin-node client to available for the server.

munin-node

Note : If you modify the configure file “/etc/munin/munin-node.conf” you will need to run the following command to re-read the configure file.

service munin-node restart

You can follow the “Client Side” configuration for the rest of clients/nodes.

Hope thats work for you!

In my scenario, I will use Php 5 as module and Php 4.4.9 as cgi-script with Apache on CentOS 5.2.

Step 1 : Installing httpd and latest php from default CentOS yum repository.

yum install httpd php

Step 2 : Downloading Php-4.4.9.

mkdir -v /temp

cd /temp

wget http://au.php.net/get/php-4.4.9.tar.bz2/from/ca.php.net/mirror

tar -jxvf php-4.4.9.tar.bz2

cd php-4.4.9

Step 2.1 : Installing Php4.4.9. Make sure you configure and compile as it is mentioned below.

Note : Do not add support for apxs, it will break up the default php5 module for apache.

./configure –prefix=/usr/local/php4

make && make install

cp -av php.ini-recommended /usr/local/php/etc/php.ini

Step 3 : Now configuring Php4 as cgi-script for apache.

ln -s /usr/local/php4/bin/php /var/www/html/cgi-bin/php

chmod 755 /var/www/html/cgi-bin/php

Step 3.1 : Adding support Php4 in apache.

cp -av /etc/httpd/conf.d/php.conf /etc/httpd/conf.d/php4.conf

vi /etc/httpd/conf.d/php4.conf     # Add the following in it;

Action php4-script /cgi-bin/php

AddHandler php4-script .php4

AddType text/html .php

DirectoryIndex index.php4

service httpd restart

Thats it! Hope it works.

Comments are welcome.
