Seeking a p2p program to run exclusively on a LAN

[klowne]

Hi, at university we have a large LAN connected to the internet through a transparent gateway. They are very strict about p2p programs (presumably due to bandwidth expenses and network slowdowns) and their standard response to detecting them is to permanently disconnect the user from the network.

Presently most people run iTunes which only shares its collection within the local network - it doesnt connect to anything outside the LAN and as a result noone gets into trouble. People then download using MyTunes. This is fine except it only works for MP3 and AAC files and the latest version has some annoying restrictions.

I was wondering if anyone could suggest a p2p program that can be run and easily set up on the computers in the LAN that will definately not connect to the internet and get anyone into trouble, lets us share anything we want and hopefully doesn't have any spyware, etc.

Thanks

WASTE works fine on a LAN; it uses only IP numbers that you give to it (so no unexpected Internet connection attempts); it is fully decentralized, so no need to run any server; you can share any file types on it; it has group and 1-to-1 chat; it is open source and contains no ad- or spyware; and as an additional bonus all traffic between users is encrypted so only the users in your sharing group will know what you are chatting or sharing.

Try Rodi
all relevant links here
http://larytet.sourceforge.net/tryRodi.shtml

500K of binary if you run GUI and ~300K without GUI
0% CPU all the time, under 30M of RAM - usually in 25-30M range

multisource download is supported

the network is searchable and does not require any servers/super nodes/etc
to search the network you need only port number of the peer(s), for example 31211 and IP subnet, for example 192.168.0.0, no permanent IPs are required

client is implemented in Java and tested both on Windows and Linux
number of peers in the network is not limited (scalability of the current code was tested for ~1000 peers)

supports both standalone and applet mode - yes you can run it directly from any HTTP server without installing anything. you sit in your Univesity lab, you have a couple of minutes, you go to SF.net, you run 300K Java applet (CLI engine), a couple of commands and you are connected to your PC at home or any PC in the network.

feel free to ask questions on the discussion boards linked above

P.S. and i forgot the most important thing - you do not need any forums and discussion boards to use Rodi network, you don't need registration, you dont' have to worry about somebody loggin your IP address when you post your public key or PGP signature. Rodi is free as in Freedom open source project and available for everybody from SourceForge servers.

Thanks guys, I'll let you know if I run into any trouble trying these.

Slightly more preferable though would be if I didnt need to specify the IPs so that the word could spread about the program and people easily set it up. Am I right in thinking that Rodi could do this with everyone using the same port so people setting it up only need to know that?

default port

:1337

Good luck klowne

If you ever run into any problems, try this thread for waste setup to get you started... http://www.p2p-zone.com/underground/...ad.php?t=19077

Default port in WASTE does not help lot, because you need still somebodys' IP address to connect to the network and usually this is permanent IP of running 24/7 host.

because network is essentially small isoltaed groups you will have to find and join group with content you are looking for and this is not an easy task. Rodi network is fully searchable. Your ability to search the network is only limited by upstream you have (see my previous post).

Performance of the WASTE network degrades quickly when you add hosts. My wild uneducated guess that for LAN 100 hosts is probably all you can do.

Not to say that WASTE is useless. If you are a group of dissidents who want to talk with each other and dsitribute doc or pdf file once in a while WASTE is fine.

yes that's right. rodi client finds peers using IP scan. For example, let's say that your network is 10.19.x.x or up to 64K hosts. with 10Mbit/s connection you can find all peers assuming that port is known in 5s (see http://larytet.sourceforge.net/useCa...torlooktraffic)
This is pefect for LANs. you do not need any centralized server where peers should register, etc.

Usually subnets you will have to scan are going to be much smaller. For example, 192.168.11.x , 192.168.41.x, etc. 254 peers per range.
Peer is searchable immediately afer it run the client. If asked peer does not have what you are searching for peer will send you set of IPs of other peers. This way the moment you find one peer in the netwok you learn more IPs and so on.

Try ShareScan. It's like a glorifed Explorer without having to click all the clients with shared folders.

http://www.filelibrary.com:8080/cgi-...0/ss2_45in.zip

Doesn't use the internet and browses all shared files/folders on the network.

....ShareScan is a simple network security tool. It provides a very fast way, via multi-threaded processing, to detect shared (Windows) network resources, that could provide a potential security threat to your network. Scanning can be of any number of connected computers represented by a range of IP addresses. However, the evaluation version is limited to the first 10 IP addresses in ...
