Recursive Folder Content Hash Script

2011-10-23T19:45:00.000+05:30

Keep hashes of the folder helps to keep integrity of contents. Specially for a web server this is very important to identify potential Remote File Intrusion incidents.

This hash calculator is written in python and possible to run cross platform. Both Linux and Windows were tested. Md5 hash, sha1 and sha512 hashes can be taken with each script.

Open python script from text editor and insert the folder location where hashes are needed. And run it in command line 'python hash-calc-md5.py' like wise.

Python 2.7 is needed to run these scripts.

Adding Bookmarks and Hyper Links to LaTeX Content Page

2011-09-25T03:03:00.000+05:30

Kile Logo

Handling and creation of large documents which have more than 100 pages are not easy task with Microsoft Word and Libre Office Writer like word processing packages. After the limit of 50 pages, time spend for formatting significantly increasing in GUI word processors. Therefore best option is switch to LaTex.

In LaTex content page can be generated with single line. That is adding
\tableofcontents tag. However even it generated a good content page, after making the PDF, the book marks and hyper links from content page to relevant sections are not created. To overcome this issue, 'hyperref' package can be used. Just you have to do is add following content to your document between \documentclass tag and \begin{document} tag.

\usepackage{hyperref}
\hypersetup{
    pdfborder = {0 0 0},
    bookmarks=true,         % show bookmarks bar?
    unicode=false,          % non-Latin characters in Acrobatâ??s bookmarks
    pdftoolbar=true,        % show Acrobat??s toolbar?
    pdfmenubar=true,        % show Acrobat??s menu?

    pdffitwindow=false,     % window fit to page when opened
    pdfstartview={FitH},    % fits the width of the page to the window
    pdftitle={Sample LaTex with Link},    % title
    pdfauthor={Kasun Chathuranga},     % author
    pdfsubject={LaTex with Link},   % subject of the document

    pdfcreator={Kile},   % creator of the document
    pdfproducer={}, % producer of the document
    pdfkeywords={}, % list of keywords
    pdfnewwindow=true,      % links in new window
    linkcolor=white,          % color of internal links

    citecolor=green,        % color of links to bibliography
    filecolor=black,      % color of file links
    urlcolor=cyan,           % color of external links
    colorlinks=false,
    citecolor=black,%
    filecolor=black,%

    linkcolor=black,%
    urlcolor=black
}

This hyperref package is available in Kile by default.

Step 4: Extract swt-X.X-gtk-linux-x86.zip to temporarily place and copy swt.jar
Step 5: Replace swt.jar in Vuze folder with one from extract swt-X.X-gtk-linux-x86.zip
Step 6: Now run vuze script in vuze folder. (Just double click or launch in a terminal)
Now you can see Vuze is running

Install w3af 1.0 in Fedora - Python-svn Dependancy Solving

2011-05-26T02:14:00.001+05:30

Famous web application testing tool kit 'w3af' released a stable version on 25th May 2011. How ever when I run w3af-gui, it tells it needs 'python-svn' and suggest to run apt-get install python-svn.
In a fedora based system 'yum install python svn' will not work since package comes with a different package name. Therefore to install python svn, 'yum install pysvn' should be issued.

Installing Broadcom 43xx Wireless Drivers after Kernel Update in fedora

2011-05-10T18:05:00.002+05:30

Broadcom Logo

After a kernel update in Toshiba Satellite laptops which are running on fedora may lose the wireless network capability which is based on Broadcom chips. Even drivers are available from RPMFusion repo, it will take couple of days to update drivers with newly released kernel. Best option is compling the driver as following steps which gives wireless capability instantly.

Step 1:
Run 'lspci | grep -i broadcom' in terminal to make sure wireless hardware is there.

[kasun@katalyst ~]$ lspci | grep -i broadcom
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g LP-PHY (rev 01)
[kasun@katalyst ~]$

As in this example it is BCM 4313

Step 2:
Run 'uname -m' on the terminal and get the system architecture to know whether it is 32 bit or 64 bit.

Step 3:
Remove any previous installed wireless drivers if something shows after run this command in terminal as root.

lsmod | grep "b43\|ssb\|wl

If any of these are installed, remove them:

rmmod b43

rmmod ssb

rmmod wl

To blacklist these drivers and prevent them from loading in the future:

echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf

echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf

Step 4:
Download the driver source from as match to system architecture (32 bit or 64 bit)
http://www.broadcom.com/support/802.11/linux_sta.php

Step 5:
Install gcc, kernel-headers and kernel-devel package if you not installed. Use

yum install kernel-headers

yum install kernel-devel

in terminal as root to install these.

Step 6:
Un tar the archive.

Step 8: Run make install.

[root@katalyst wget]# make install
install -D -m 755 wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless/wl.ko
[root@katalyst wget]#

Step 9: Insert compiled kernel module by entering following commands.

modprobe lib80211

insmod wl.ko

[root@katalyst wget]# modprobe lib80211
[root@katalyst wget]# insmod wl.ko
[root@katalyst wget]#

After several minutes wireless connection will be shown in network manager.

Step 10: To load these complied kernel module at boot time enter the following commands.

cp wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless

depmod -a

echo modeprobe wl >> /etc/rc.local

[root@katalyst wget]# cp wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
cp: overwrite `/lib/modules/2.6.35.13-91.fc14.x86_64/kernel/drivers/net/wireless/wl.ko'? y
[root@katalyst wget]# depmod -a
[root@katalyst wget]# echo modeprobe wl >> /etc/rc.local

In above Step 10, it might asked overwrite existing wl.ko. In this case enter y.

Open DNS Phishing Protection

2011-05-08T03:14:00.000+05:30

Open DNS Logo

As a Linux user, since there is not reputed Virus Guard (Even troublesome SELinux is there) or URL filtering is not done, there is a more chance you deal with phishing URL. In windows many AVs prevent phishing and scam URL. In this case best option is using a DNS level filtering. In most cases ISP's DNS will not offer this sort of protection. Therefore best option is switch to Open DNS.
Open DNS name servers are

208.67.222.222
208.67.220.220

These name servers can be entered in Network Manager. If you use DHCP, just select IP only. And then enter name servers with commas.

Open DNS at Network Manager

After this configuration change, using web browser will be little more safe than early.

Blocked Phishing Site

How ever implementing chain of protection is makes much safe. Using Open DNS, and using Firefox with add-ons like 'Web Trust' and 'LinkExtend' will make more security. As final thing using 'NoScript' like add-on make more more better. Even it make little probalemtic, XSS and click-jack protection is very very imprsesive.

How to fix Oracle VirtualBox Ubuntu 11.04 Unity Hardware Requirement Issue

2011-05-03T00:28:00.003+05:30

Oracle VirtualBox VM boot Screen

Unity is the new desktop package which is included in Ubuntu 11.04. How ever this makes small problem to VirtualBox testers for Ubuntu. It gives small error contains hardware is not support and Unity is kept disabled.

Unity Hardware Required Error

To enable Unity back, a very small setting change has to be done. That is increasing Video Memory to about 64MB where the default value for Ubuntu virtual machine is 12MB. Also enable the 3D accelaration.

Display Setting for Ubuntu 11.04

Then Unity works smoothly.

Ubuntu 11.04 with Unity in VirtualBox

How ever my favorite feature in Ubuntu 11.04 (Natty Narwhal) is, it allows install Adobe flash player, Java run time and Gstreamer pluggins automatically by putting a small tick mark in installation process.
