How do you Identify the interface of a packet while listening to network traffic on all devices?

由 ≯℡__Kan透↙ 提交于 2019-12-08 10:54:43
I am writing a python program that needs to listening to traffic on all networking devices and identify packets based on their incoming interface. To listen on all interfaces I started my capture without specify a device, but I am unable to denote the interface of a particular packet. How is this done? Matt Ball I assume that the MAC address is sufficient information for you. The first 6 octets of a packet is the destination MAC address, which is immediately followed by the 6 octets of source MAC address.

How can I edit a js file sent by the server before it gets to my browser?

由 为君一笑 提交于 2019-12-07 23:01:45
问题 During a normal browsing session I want to edit a specific javascript file before the browser receives since once it gets there it's impossible to edit. Is there are any tool for this? For what I need it I can't just save it and edit it on my disk. I'm ready to learn how to program it myself but if anyone can point out more or less what I have to do I'd be very grateful. I'd have to intercept the packets until I have the whole file while blocking the browser from receiving it any part of it,
