i have implemented a c program where raw packets are received from the network and saved in a binary file. Thing is i cant open that binary file. i tried opening it using terminal,but i am getting permission denied.

I used 

sudo ./sniff_data.bin

and its displaying 

sudo: ./sniff_data.bin: command not found

  • If you're getting packets from some sort of sniffer it is probably running as root, and the data probably needs appropriate permissions set before you can read it. – chronitis Nov 06 '13 at 09:17

Regarding 

sudo ./sniff_data.bin

A bin file is NOT an executable. You need software that can open a BIN file to view the BIN file.

What you want is probably

sudo hexdump sniff_data.bin

Another method:

sudo strings sniff_data.bin

This will show all the text strings inside the file.

For graphical methods viewing binaries see: What are some good GUI binary viewers/editors?
