Re: Running TCPDUMP over a web interface

[Tek Bahadur Limbu <teklimbu () gmail com>]

Hi Guy Harris,

Thank you for the reply.

My goal is to have a web interface and capture traffic and print in on
the screen live but only when a certain command string is supplied.
As stated, I need that web interface to be run over a Linux bridge box.

For the time being, I only need this web tool to run the traffic dump
over the br0 interface of that bridge with something like the
following options:

 tcpdump -enn -i br0 vlan 999

Can you provide further information about how we can go about
implementing this setup?


Thanks,

Tek Bahadur Limbu
