DC++

cologic

You're wrong. Even within computer math, virtually none of the C-based languages use ^ to signify exponentiation (they don't tend to have an operator for it). Mathematica appears to use it, as does BASIC. Fortran uses **. It's "in standard math" not the exponentiation operator, either; I recall from...

I don't enjoy getting banned (yes it has happend) just for connecting to my favorite hub when running Linux. So lobby those hubowners to use less pointless agressive CDMs/scripts/client filtering. This is one reason, in fact, that I haven't become all that interested in a DC++ port to Linux; I'd ra...

cologic

I should probably mention that ADC looks somewhat likely to become eventually adopted, so one should probably be aware of it whilst discussing DC replacements.

cologic

It guesses, and I've seen it do so incorrectly many times.

Nick1 is on your hub.
There's a separate Nick1 on another hub.
Should that other Nick1 also get the distribution hub auto-slot?

cologic

I dont want to know from what hub somebody connects to me

I want to know if he's in my hub.

Haha.

cologic

Slots are a poor abstraction for bandwidth, which is the more real (ISP-imposed) limitation for a P2P user. One might look into changing their nature if one wishes for multisource downloading.

cologic

other p2p networks

The separation of hubs is one difference between DC and a lot of "other p2p networks", one I very much appreciate.

I don't trust ops I don't know more than I do users I don't know

My primary objection to this makes no distinction between ops and non-ops.

cologic

Private hubs are called "private" for a reason...

cologic

This assumes both that (1) it's acceptable to reveal exactly what private hubs one's on, and (2) you have the ability to log on to them.

Address them, and I'll think about it more.

cologic

How does either making the commands available for all or creating $GetAllNicks rescue your broken idea?

cologic

Multiple hubs.. (To op on hub1: I'm uploading to people on hub2. To op on hub2: I'm uploading to people on hub1.)

cologic

u can also tiger hash an entire file..

I'm curious whether you can find an example of this in the wild. SHA1, by contrast, is very common in this role.

cologic

Nothing wrong with a little bier.

cologic

No, but using the Lua support allows one to do this...

Surely you meant something more like: Let's say you try to prove the sourcecode ('source code' is two words.) easy to understand. OK. You're right. I don't like to argue with people with a closed angle (I don't think this is quite the expression for which you're looking. Perhaps 'closeminded' accura...

1) What was the problem with MFC? Wasn't it just good enough for you? Was it too hard/buggy to use, so you decided to reinvent the wheel and start creating another interface to help you? MFC is large (look at the size of the binaries it generates), and no easier to use than WTL. Further, WTL isn't ...

cologic

Have you seen DCTNG?

cologic

I really should read the MFC code (I'm a bit "affraid" of MFC...), to maybe learn how the client code really works.

Well, it's actually WTL, not MFC.

btw, is there some documentation of DC++ somewhere?
(except from the docs generated by doxygen)

Not to my knowledge.

cologic

(1) Yes, opening multiple listening ports 'solves' the problem for active users. However, it doesn't for passive users, and allowing such a large gap in functionality between the two would be unseemly. (2) As far as cyberal's suggestion, what about multihomed hubs? Better is to have $CTM pass on a r...

cologic

See http://dcplusplus.sourceforge.net/forum ... php?t=4446 for more detail about it. It's mostly aimed at those who understand the DC++ code some, but it sheds a bit of light on the issue.

cologic

NMDC, DC++, and DC GUI users are also potentially fakers.

cologic

I should probably clarify, to preempt the 'yeah, but you can't trust the protocol, it hasn't been analyzed' posts: I know. I/one can't trust the protocol, and it hasn't been analyzed outside of a couple of mailing list posts written in a few minutes (though the flaws they've pointed out have been fi...

cologic

Edit: er, unless you're talking about the non-DCTC based 'dcgui' client... Damn similar names...

cologic

Yes, and anyone who doesn't use one of three approved clients (note that there's no half-decent Mac client in there, as the NMDC one, well, isn't) is a faker.

cologic

LibTomNet, apparently, has been recently released, and though he "STRONGLY [RECOMMENDS] against people using this in field systems", it looks promising nonetheless.

cologic

So find the file containing hashmanager (it's not a difficult name to guess), and add it to the appropriate project (GUI -> DCPlusPlus, other->client). *shrug* Repeat for whatever other compiler errors pop up, and make sure you're following compile.txt... Edit: reading the error messages does help :...

cologic

The additional files bitprint.c, sboxes.c, and tiger.c have to be added to the client project as well; however, you can avoid this process if you just use the .sln, rather than the VC6 workspace.

cologic

You're apparently using the VS6 projects, which I don't maintain. You have to add a few files to the client and DCPlusPlus projects: client: HashManager.cpp DCPlusPlus: UploadQueueFrame.cpp, Advanced3Page.cpp, BandwidthLimitPage.cpp There may be more, but those certainly need to be part of their pro...

... (probably) noticeably increasing bandwidth demands on the hub, but I guess that's something that can be measured and which you may find a suitable tradeoff.

cologic

Respond to my previous post, please. I could restate it all, but... Not worth it yet, because you haven't even tried to respond to it.

cologic

Whilst all of TCP's flow control and reliability features can be implemented over a UDP substrate, they would seem to require interaction between the two clients. Spoofing one's source address makes such things significantly more difficult, in particular.

cologic

Any competent programmer who has "developed more than 200 000 lines of C code and about of 50 000 lines of x86 Assembler code" should be able to figure out how to modify a small program such as DC++.

cologic

I should probably mention now that I wrote tigertree hashing code for my DC++ mod several months ago and have been playing with it since. It correctly calculates an hash trees to an arbitrary depth, stores them in a file for later retrieval, updates that file (albeit inefficiently), searches based o...

Update your Platform SDK; it's a free download from Microsoft.

cologic

setting the rollback to 0 will have fixed it.

Ugh no.

I propose a check in DC++ such that one cannot set the rollback to 0, and to additionally pop up an explanatory message as to why it's fucking stupid.

cologic

Doesn't work in passive mode (obviously).

cologic

It would be nice; however, all that the other user sends is his nick. That's not enough to reliably distinguish between two hubs.

cologic

Create a foolproof way to identify what hub a user's from, and it becomes possible.

cologic

Having a hard time comming up with new stuff to write huh?

No, but posts such as that one are so much more fun, and someone else eventually brings up what I was going to post anyway.

cologic

Yoshi: We probably won't be able to prevent you from instituting $ClientVersion, as you say.. Useless protocol extensions will always be possible and if you don't screw up and I don't belive you will there won't be a way of telling your hub not to this. But I think this isn't what you should aim at....

bitzi maintains such a database.

As far as practical advantages, using a merkle hash tree (of whatever hash algorithm, e.g. tiger) ensures that a network doesn't lock itself into a fragment size, as eDonkey/eMule has done.[/url]
