tcpdump

Is TCPDUMP comes with Ubuntu 13, if yes then how do I use it?

[bashiergui]

Simple enough to find out by typing in a terminal

tcpdump

If it's not installed type in

sudo apt-get install tcpdump

To learn how to use it type

man tcpdump

or go to this link http://manpages.ubuntu.com/manpages/...tcpdump.8.html

How do I install TCPDUMP in Ubuntu? or does it come with Ubuntu already, if yes then where can I find it?

Please don't start multiple threads on the same subject.

It is easy to use once you get the syntax, which is simple. Here is a basic tutorial:

However, maybe you want something graphical like Wireshark?

when I install tcpdum I receive this message "You need to be root to perform this command", I don't know why this I happens

[memon_saifullah]

Ok, I've Installed it as you suggested, but when I write tcpdump in terminal following message appears
"tcpdump: no suitable device found"
how do use access it

[memon_saifullah]

but when i use it this is displayed in response "tcpdump: no suitable device found"

tcpdump needs to be run as root. The tutorial mentions it indirectly, but does not come out and say it explicitly.

sudo tcpdump

Same for wireshark, except use gksudo instead of sudo.

sudo apt-get install < pkg_name>

Thats the command to install any package in ubuntu.

you have to be root to install any package.
