network tools for wireless and wired

Security tube contains group of tools characterized by the name "Tutorials on commonly used Security Tools" for wireless and wired networks. It provided video explanation for each tool. So what are you waiting for.............

Other than this you can find some other tools which are available. have look...

how to install madwifi driver for linux with and with out resend packets option.

Madwifi driver is basically written for Atheros chipsets and it supports most
It is a open source but depends on the proprietary Hardware Abstraction Layer (HAL).

Download and Check

$ wget
$ tar -zxvf madwifi-0.9.4.tar.bz2
$ cd madwifi-0.9.4/
$ cd scripts/
$ ./madwifi-unload.bash
$ ./ $(uname -r)
$ cd ..

If your doing protocol test and you want to have control how many packets are going from your wifi interface. You need to do simple two steps before compiling.

step 1:-

In madwifi-0.9.4/ath/if_athvar.h file change line '#define ATH_TXMAXTRY 11' to '#define ATH_TXMAXTRY 1'.

step 2:-

In madwifi-0.9.4/ath/if_ath.c file change line 'sc -> sc_mrretry = ath_hal_setupxtxdesc(ath, NULL, 0,0,0,0,0,0);' with 'sc-> sc_mrretry=0'.

In place of '0' you can write FALSE and add macro for it.

Now start compilation.


installing pcap2air and other airbase tools for wifi

To work with airbase wifi tools we need to have lorcon.
Lorcon is a bookshop specializing in frame insertion for 802.11 (Wi-Fi standard) and is on suite that supports the Airbase. The suite is created in C + + and is formed by applications, Airware-test, fuzz-e pcap2air,pcap-match, pcap-tac, pcap-wepcrypt, prism-strip simple-replay.

Currently, some programs use functions Airbase Lorcon bookstores that are considered obsolete (Deprecated).We'll see how to modify the code to fit the new libraries.

Download and install Lorcon (SVN):

$ svn co

(If svn client is not isntalled on your machine just do #yum install subversion)

$ cd trunk/
$ ./configure
$ make
# make install

Download Airbase 2.40:
Files to modify:

airbase-svn-223/80211fp/jc-CTS-printer/src/boring.cpp airbase-svn-223/80211fp/jc-CTS-printer/src/boring.cpp
airbase-svn-223/libs/lib802finger/src/station-lister.cpp: airbase-svn-223/libs/lib802finger/src/station-lister.cpp:

airbase-svn-223/tools/fuzz-e/boring.cpp airbase-svn-223/tools/fuzz-e/boring.cpp

To modify:

We just replace these lines of code file containing:




Installing Airbase-release-2.40:

$ tar -zxvf airbase-release-2.40.tar.gz
$ cd airbase-svn-223
$ cd libs/libairware/
$ make
# make install
$ cd ../../tools/
$ ./
# ./

# ln -s /usr/local/bin/airbase/* /usr/sbin/

If any tools complain about missing shared library then

cp /usr/local/lib/ /usr/lib

Now bellow airbase tools will be available
