0.tgz.
The files will uncompress into a new folder named packit-1.0.
Spoofing 285
Change to the new directory by typing cd packit-1.0 and pressing Enter.
Configure the Packit application for the specific machine it is on by typing
./configure.
Packit will configure for the specific machine.
286 Practical Hacking Techniques and Countermeasures
The next step is to create the executable by typing make and pressing Enter.
The Packit application will be created.
Spoofing 287
Install the Packit application by typing make install and pressing Enter.
The Packit application will install.
288 Practical Hacking Techniques and Countermeasures
To capture all packets, type the following syntax:
./packit ??“m cap
The ??“m cap tells Packit to run in mode capture.
The packets will scroll on the screen.
Spoofing 289
To tell Packit to capture only TCP traffic, type:
./packit ??“m cap 'tcp'
From the syntax above, only TCP traffic will scroll on the screen.
290 Practical Hacking Techniques and Countermeasures
To capture the first 100 packets and save the data to a file, type:
./packit ??“m cap ??“c 100 'tcp' ??“w 100packets.txt
The ??“c 100 tells Packit to limit the captured packets to 100.
The ??“w 100packets.txt tells Packit to write the results to a text file named
100packets.txt.
In this example, the first TCP 100 packets will be written to a file named
100packets.txt.
Spoofing 291
The 100packets.txt file is written.
