Are you asking whether tcpdump is written in C or C++? If so, it's written in C. If not, please clarify your question, because it doesn't really make much sense.

think he wants the source code for tcpdump but hell i cant even make sense out of it

The source can be found here. You'll probably want to read through the documentation for libpcap as well.

Nylex? You've done the impossible:hattip:by providing JUST the answer while including suggestions too

REGARDLESS of the grammar and getting STRAIGHT to the point (time is money)!

Here in U.S., we've proven this to be very difficult to do thus, I dedicate my very first post to you while appending my 2c as well:

Syntax Examples:

Code:

tcpdump -i eth0

Displays everything communicating via eth0 (yours may vary; Ex:eth1,wlan2,etc..) to and from while the '-i' represents "interface"; straight-forward code.

Here's my favorite:

Code:

tcpdump -i eth0|awk '{print $1,$3,$5}'

This will filter the output and only show the Time, Data_From and Data_To.
