How can i share a file using UDP protocol on network?

[coringa2112]

Hi folks, i use a LAN connection, and i need to share a CSV file, but i need it to transfer only using
UDP protocol, just sending my CSV data to other computers, how can i configure my network to send this CSV using UDP protocol? thanks

This HAS to be a homework or test question. WHY must you transfer via UDP?

 

[coringa2112]

i need it because UDP is like using data diodes, and more secure, so how can i share my csv file and it use UDP protocol instead of TCP? thanks

"but i need it to transfer only using UDP protocol"

Please describe 'why'?
It doesn't work like that.

So which textbook gave you that BS... If you believe that not getting an acknowledgement of your network traffic and being able to resend missing data is "more secure" because there is no bidirectional communication, then you have still have a lot of PRACTICAL things to learn, IMO.

And Googling "udp file transfer" could NEVER provide any possible answers ...

ok maybe its not 100% secure, but i personally think its very secure to protect a computer on my network from sending any data, because it will only receive in a unilateral system. I would like to know if its possible to make this CSV file be shared using UDP protocol, and if its possible, how can i do it?

Oh dear.....

And I personally think I can make monkeys fly outta my butt.

You wish to do this?
OK...

Games use UDP.
Encode your CSV into a video game stream. Have it be some 'object' that the user can 'pick up'. Like a sword or something.

I'll leave the implementation details up to you.

 

[coringa2112]

come on, how UDP is not safer than TCP, in TCP if you dont receive data you cant send files,if you need a computer that never send any data out, it
has to be UDP, right? The top security device is called data diode, what they basically do is do something like UDP but on hardware, so i really think its secure.
I'm not asking much, just a CSV file with 100 kbs being shared every second on my network using UDP, please guys, point me on the right direction, i need to know how to do it in a simple way, thanks

 

[USAFRet]

Dude....there is no "right direction" to point you in.

Somehow, you seem to think that your 15 minutes of investigation is somehow more 'secure' than decades of actual network deployment.

What you're asking for is akin to wanting to run the house electricity piggybacked onto your plumbing pipes.
Doesn't work like that.

LAN->File and Print sharing->Shared folder. Done.
Instantly and continuously available.

Other than that, I'll leave the implementation details up to you.

Although UDP means user data protocol many people call it UNRELIABLE. Especially with the method you are talking about how would the sender ever know if you machine receives the data if you never respond to anything. So if a packet is damaged it is gone. If your file transfer can tolerate missing data it will be find otherwise you just get corrupted files.

This is not security it is more you can pretend nobody knows you are receiving it.

You are going to have to pretty much write this yourself. The sending machine will send to the broadcast IP so it is sent to all machine on the network. You need a program that can recognize the traffic. I suppose you could use wireshark and then try to process the capture file with a program.

Then again if you really want to use UDP use TFPT to do it. Still your machine will need to send messages back, they are using the TFTP application itself to solve the problem of damaged data packets rather than doing it at the low levels in the stack by TCP

 

[coringa2112]

it seems to complicated, ok i give up, thanks for the advice folks

Reminds me of this Dilbert: http://dilbert.com/strip/1995-12-31

 

[aufgarreg]

you don't need to call me stupid, there is an article called "protecting confidential information using data diodes" by nexor.com, that explain it.
You're calling the government stupid, because they use the same thing i'm asking for security. I just need to send 100 kb of data every second to another computer on my LAN using UDP protocol , it's asking too much? I really cant believe you guys can point me on the right direction for something that should be so simple

 

[USAFRet]

I'm not calling *you*, (or really, your other account) "stupid".
It was just a Dilbert cartoon.

What is the security need for this data transfer? Something that simple permissions can't handle?

 

[coringa2112]

i`m a little paranoic about intel ME stealing my data, nothing illegal, but my work, i want nobody with acess to my developments in my works, i`m sure UDP protocol is the way to go, as its basically a software diode, but it seems very difficult to send even a csv file, nobody know how to do it

MERGED QUESTION
Question from coringa2112 : "I need help, i can receive the packet, i can see on wireshark, but where is the file?"

Hi friends, i'm trying to make a csv file be shared on my LAN network using UDP protocol, some members told me it was impossible, but not so much, there is a program called packet sender, and i'm lucky that the csv file is small so i can send it using only 1 packet every second, but then i question, i can see the packet being received on wireshark, but where is the file? Please i need help i'm almost completing what i need, i'll really apreciatte any help

Pretty sure you'd need some sort of application running on the receive computer to receive and save the packet(s). Is there a packet receiver' program available from the same source you got packet sender, or maybe packet sender can also act in receive?

no where, the receiving end need to know and write the file.

the program is open source called packet sender, i need to install it on my other machine? these packets i receive are not saved anywhere? thanks for any help

UDP packets are not automatically written to a file. You can use Wireshark to save packets, but the csv data would need to be extracted.

great, i can see on wireshark, but how can i convert these packets in a csv file?

thanks a lot man, wireshark is the way to go, god bless you
