Available online tftp servers

Question

Are there any TFTP servers which I can contact in order to examine traffic using Wireshark or do I need to start my own TFTP server on localhost

Answer 1

Download Serva which includes a TFTP Server and Client. You can even transfer files within the same PC targeting a loopback address. (localhost or 127.0.0.1).

Answer 2

To examine TFTP traffic, you need to be connected on a network where there is TFTP traffic. So, if you sniff the traffic when sending files to a distant TFTP servers, you'll see :

• What the TFTP server sends to you
• What your TFTP client (your PC) sends to the TFTP server

So, what you need to do is :

1. Download a TFTP Client
2. Run wireshark and listen to traffic
3. Send files to a distant TFTP Server opened to everyone

Otherwise,

You can also run a TFTP server on your own computer, there are severals existing software but you'll also need a TFTP client.

• You may use as example for the server any TFTP, I use for my works Pumpkin
• And any client, for example TFTP Client for Windows

I also suggest you to consult the RFC 1350 protocol documentation about TFTP.
