Gnutella1 simple simulator
 

Hi everyone,

I am new to this as you can probably tell. I was hoping to program a simple simulater that only does query and queryhit for ttl 3 and ttl4. I have two text files one with 100 network and with resources.

i was hoping to read in those files and get some results to be outputted on another files. i want to see the recalls and the network traffic so i can compare tt3 and ttl4 results. And i need to generate 1000 random queries with the node id and target resource.

Problem is i dont know how to start this and programming language to use. I know a bit of .net, and php but i just dont know how to start.

If anyone can provide me with some directions i will be greatful. Thank you in advance.

Sorry, simple isn't very easy...

You can try getting the Phex code and understanding it (Java-Code), but you'll need some time to get everything up.

First have a look at the how Gnutella works:
- Main Page - Gnufu - concepts explained
- Gnutella Protocol Specification - Gnutella Specification - exact specifications

Hi, Thank you for your reply.

I have looked at the link it seems too complecated, all i need is a little program of about 200 lines and out puts the results from 20 random queries, (i am only using query and queryhit, not ping or pong) on ttl3 and 4.

I think the basic idea would be to open a connection to each of the nodes (whether you just pick a random set of nodes or otherwise), send the query to each, then reading data back over the same connections.. once you get a result you just parse out whatever information you need from the response and write to a file...

I know that i have to declare things like query, queryhit, ttl3, ttl4, read in files, etc

I just dont know how to start it, to be honest... So any help would be appriciated.
