Packets (networking) question

[babadoctor]

Hey guys

 

I have a question about packets (networking). I was wondering if its possible to send (packet type) packets over the internet from one location to another, to a specific user on the other network? If i could how could i? Is port forwarding needed?

Packets are how data is formatted. By replying to this thread, you are sending packets to the LTT server for them to be uploaded here. To be more specific, packets are the Layer 3 Protocol Data Unit, and I don't really care to go into much more detail at the moment.

So what if i wanted to send a deauthentication packet over UDP?

The FCC gets really pissed off considering it is illegal to deauth. There area major grey areas of deauthing, but for the most part, the FCC sides in favor of don't do it because denying access to a client is illegal.

My college class where the instructor is the network admin for GVSU in Michigan - he is the head admin of their wireless network

 

Proof that it is illegal as documented by a lawsuit against Marriott: http://www.fcc.gov/document/marriott-pay-600k-resolve-wifi-blocking-investigation

Any IP or IPv6 data sent is a packet. Absolutely every Layer 3 piece of data sent on a network is a packet. The structure of the packet will vary immensely from packet to packet, depending on what it is meant to do. You aren't being specific enough for me to give a good reply. In order for me to create a good reply to this topic, I'd have to know specifically what type of packet it is you're sending or wanting to send. Your best bet to understand this is definitely going to be taking a class on it at college (assuming you're old enough for college, noticed your profile has your age hidden) or at a tech center/high school that has networking classes.

im 13 ): are there any good topics on here that talk about it or anything online that talks about it?

Not that I'm aware of. Cisco has always had great material and that's where I acquired all of my networking knowledge to date. See if there are any free topics you can look at from them.

okay! thanks

I'd recommend researching the OSI (Open Systems Interconnection) model then TCP/IP protocols to gain an understanding of packets, as mentioned it's simply one part of what is applied/done with data before it's transmitted or when it's received.

 

Basic knowledge of computer systems is enough to understand the OSI model, it's made up of 7 layers and as mentioned Layer 3 (Network) deals with what is known as packets.

 

It seems like you may already be familiar with this, so encase I misinterpreted the question. I'll add that I've rewritten this paragraph repetitively and will simply say,when sending packets over the internet that having their IP address and utilising the appropriate protocols will allow you to send a packet.

 

 

I hope that was useful, you seemed to get specific rather quick but I though that the above was worth a mention.

OP is looking for more info. I'm a quarter away from my associates and CCNA certification, so I hope I have a fair idea, lol. Its been a while since I did the basics, but yeah, assuming OP understands your post, you did a much better job explaining than I did.

Wow, thanks! That gives me a better understanding of how packets work. I will still do more research online about this to learn, just for the heck of it :3

If you want to read a great book on computer networking, I would suggest Computer Networks 5th Edition by Andrew Tanenbaum.

if you want to know how to send UDP packet in practice

use "DatagramSocket" in java
