The BearShare BlackHole Test

#1 (**permalink**) March 15th, 2002

Don't get sucked into the BearShare BlackHole!

Here's what I did:
Using Gnucleus I noticed that whenever I connected to a BearShare node after a while all I had was connections to BearShare.
I took the code posted to the Gnucleus forum that blocks a client by name and blocked BearShare. Now I waited for the other "clustering" client, LimeWire to connect. I got one!
Wait, wait, wait.... nothing. Still connected to one LW and some others. Some others dropped off, got some that don't give a name, and one other LW showed up after a little bit but it dropped off after a little while.
After many tests it seems that LW doesn't try to "suck" you in as bad.
Then I added code so I could see how I get sucked into the BearShare BlackHole by printing every connection attempt.
BearShare shamelessly hammers me with incoming node connections till I "submit" and connect to only other BearShare$, then magically quits doing that after it gets what it wants!
I ran this test several times, even after clearing my cache and connecting to only "other" clients for a while, all it takes is one BS connection and it's BlackHole time!
Eventually my cache filled up with BearShare IPs mostly. Isn't that nice?

Is this what you call "clustering" or is it "domination" ?

Try it for yourself, it's fun!

Could you post the code and logs from this test, so we can independently verify it?

A map of the new "clustering" network plan for Gnutella:

O = "outsider" (anyone using a non commercial client, Gnucleus, XoloX, etc..)
B = BearShare (aka BlackHole)
L = LimeWire

Code:

                O  O  O  O  O
            O O  \ |  |  | /  O O
           O \ \ BBBBBBBBBBB / / O   O  <- (ready to be sucked in)
          O \ \BBBBBBBBBBBBBBB/ /   /
         O \ BBBBBBBBBBBBBBBBBBB   O  O
        O \ BBBBBBBBBBBBBBBBBBBBB /  /
         \ BBBBBBBBBBBBBBBBBBBBBBB -
  O - O - BBBBBBBBBBBBBBBBBBBBBBBBB - RIAA/MPAA (listening post attached to home page)
          BBBBBBBBBBBBBBBBBBBBBBBBB
         / BBBBBBBBBBBBBBBBBBBBBBB \
        O   BBBBBBBBBBBBBBBBBBBBB   O - O  <- (another victim is ready)
           / BBBBBBBBBBBBBBBBBBB \   \
          O  / BBBBBBBBBBBBBBB \  O  |
            O /  BBBBBBBBBBB  \ O    |     "Vinnie$$Net"
             O    / | | |  \   O     |

                 \    |    /         |
           O     LLLLLLLLLLL     O   O  <- (soon to be sucked into BS)
            \  LLLLLLLLLLLLLLL  /   /

              /  LLLLLLLLLLL  \            "LimeWireNet"
             O        |        O
                      O         \
                      |         |
          O - O - O - O         |
         /     \       \        |
        O       O       O - O - O
        |      /       / \  |    \
    O - O     O       O   O O - O O
    |    \    |      /    |      \          "GnutellaNet"
    O     O   O     O     O       O
     \    |  /       \     \      |

So how do you like being the OUTSIDER ?

Think about what it takes for one outsider to reach another
outsider across the "BlackHole" !
Does this serve Vinnie $$$ or Gnutella?

Actually, the diagram is roughly accurate.

The BearShare preferencing code is designed to create a concentrated core base of BearShare nodes, with connections to other servents delegated to the fringe of this core.

This provides the best performance for BearShare users, and still ensures that the entire network is connected.

It was based on actual data.

You mean "other crappy non-bearshare clients are now outsiders"?

And there it is, bearshare users make you $$$ so screw the rest of the network! Use the outsiders to get files but that's about it.
You are so busted! It's amazing what little sneaky things you have done to Gnutella! No one would have known if it wasn't for these posts.
Why not just call your "preferencing code" the BearShare profit BlackHole? It sucks you in and then takes all your files!
How's your new Lexus drive?

How exactly does connection preferencing screw the rest of the network? BearShare still returns search results and allows uploads regardless of client (even XoloX).

In fact, we have discovered a small problem with BearShare's bandwidth flow control algorithms that might actually be causing BearShare hosts to be more unstable than non BearShare hosts.

So if this is true, BearShare's clustering actually *helps* the network, you ***.

I think you're just trolling.

Cyclocyde, what's the deal here?

yes, the Bearshare single-vendor-network.
