 There seems to be a maximum, when reached, the bars stop growing. That
 might be explaining why we are seeing de-specialisation? Shouldn't we
 use ratios instead?

From one of the pages, fifth line:

scale factor: 0.042384106665849686 (This is used to keep lines  64 characters)

That is, every = means about 23.6 units.

The limit is 64 characters, then the scale factor kicks in (and resizes
everything). This has NOTHING to do with de-specialisation.

Have a good day :)

 Perhaps. That would also lead to high message send times though. Freenet
 needs to know what the limit is even if you use external limiting.

Is message send time a problem? I mean, AFAIK freenet is able to recognize
links with higher latency and use them as little as possible, thus reducing
the outbound traffic over those links in favour of local
(=not-so-limited) nodes.
The other two possibilities, namely lower bandwidth for all and an add-on
to fred, look uninviting: the first because it's just sub-optimal, the
second because both it requires much work on fred (to implement the
different bandwidth levels and to test them -- how many nodes would benefit
from that?) and, for those who need the feature, does not significantly
reduce the amount of configuration work (compared to a QOS system).

Please correct me if I'm wrong! :)

Probably so. Temporary keys are lost upon restart, and it takes a while

Up to date, I do not know a way to cleanly bring down the node, where by

Re: [freenet-support] Freenet Stable Build 5039

2003-11-19 Thread TLD
This build turns off rejecting queries based on output bandwidth usage,
a feature that is unnecessary (we have other ways of limiting bandwidth
usage) and counterproductive to routing. 
Maybe so, but I doubt having a Data waiting to be transmitted value above

the routing, either.
I noticed the value notably lower in the latest builds (in the order of 
5-10 minutes) with the bandwidth usage-based queryreject; I hope things 
won't get Mighty Bad again :)

Might a I have the key you need but my band is full and can't send it

[freenet-support] Maxmimum number of connections?

2002-12-11 Thread Tld

Hello.

I have noticed that my node dies when number of opened connections reach 
50. I am using #537
I get loads of inbound traffic, so it takes less than a minute to reach 50 
connections and crash again. Then a script kicks in and reloads freenet for 
another couple of minutes, and so on.

I have tried with setting maxNodeConnections=35 in freenet.conf, but I 
still have Number of open connections: 48 or near that.
I was told on IRC that maxNodeConnections is deprecated, but I couldn't 
find an alternative directive, and noone could tell me of one. :(
Hence I ask on the mailing list, hoping someone has a solution.

I really do not want to shut my node down, and neither to make it transient 
until a more stable version appear (of either the java machine or the 
freenet jar).

Thank you :)

I am quite sure about the MaxNodes: if you have a perfect routing table 
(network is fully connected: everyone knows everyone) then you will 
probably get things with HTL=1 or something very close. On answer, you and 
you alone (maybe one or two more) will have cached the content. Hence, 
things will get much worse (if a couple of nodes go down you loose the 
files). Also, bigger tables mean more CPU consumption.
Also, results get cached in paths. If you get lots of alien keys (those 
that are not near your node's assigned key) you will loose important data 
(the one you should be having), causing great havock. Data key localisation 
is one of the things that make freenet routing algo work.
Maybe there are better reasons, or mine has a flaw in it. Anyway, that's 
what I think :)

[EMAIL PROTECTED] wrote:

RAR
- no standard (sigh), no libraries, maybe no documentation or sources to be able to reimplement it?
+ 100 files to one
+ best compression

so my vote goes to ZIP which is nearly the same as RAR, is cleaner than JAR and combines the best of TAR and GZ, without any drawbacks, comes 
right with java and ist widely spread

Well, I want to say something on that.

ZIP do NOT have the best of TAR and GZ. .tar.gz will almost often be better 
than .zip because .zip does not consider files as a unit: the archive is 
conceptually the union of small one-file compressed archives.
Wow, I sure was unintellegible.

ZIP files' central directory resides at the end of file (as you can see 
when you have a multi-part zip file), which means that if the end is lost 
you might have hard times rescuing the contents.
As for the RAR files (from the quick view of the files), the directory is 
interleaved with the files, which means that you can start reading files as 
the archive is coming through.

Also, RAR files have the ability to have redundancy (in case of loss of 
some data) and the solid archiving which ZIP files miss so much.

As for the standard/implementation/libraries, the decompressor can be 
downloaded from http://www.rarlab.com/rar/unrarsrc-3.1.0.tar.gz, C++ source 
under freeware licence. This means you can decompress natively under almost 
any platform, but for compressing you still have to resort to the official 
RAR program (not everyone might be willing to use some IA32+MS-DOS emulator 
to build archives), which still leaves room for volunteers to grab your 
files off of FN, pack them, re-upload them (maybe a bot?), then you check 
the archives' content and send them under SSK. Loads of work, nonetheless :P
Also, I'm not sure a java version can be built from the C++ version, 
perhaps because of license issues, but IANAL and really don't know if it 
would be possible (maybe a mail to the author of the sw might help with that).

In the end, I say that in freenet it should not matter the speed of the 
decompression, it should the size of the archive: the normal throughput of 
the 'net will most probably be about 4 (or more!) orders of magnitude of 
the decompression algo. Also, smaller files means more space available for 
storage, which in turn raises the chance of a key being held.
Hence, I'd say go for the best compressor available out there (to my 
experience it's RAR, but the issues might be just too many to allow its 
use) and implement that. Or, build a layer for compressors and allow future 
extensions (like, start with .zip and eventually add another (de)compressor 
in another version), but that might bring to freenet dialects, which is 
something to avoid, esp. in the first time.

'nuff said. Back to my crypt.

There is a bigger problems with actual implementation of HTLs: unless a

This means that the node you send the request to will be able to guess 
(with low probability of error!) that you are the originator of the request.
Fixed default HTL is evil. Add (signed) a random number to each request.
Fixed default maximum HTL is even more evil. To be more protected you must

Fixed default HTL is evil. Add (signed) a random number to each request.

Even that is not sufficient. If you access a site with lots of images
and many of the requests go through a particular node, then it can
deduce a probability for you being the originator, which gets pretty
high if it's a big freesite. The correct response is to implement
mixmastered first two hops, which we will not implement before 1.0.


I am not sure about what you mean by mixmastering the first two hops. I 
read it like you're talking about sending originating requests to a random 
node (no matter if it's nearer to the data), which might work as long as 
the enemy isn't all around you (in a good %).
But what about the second hop (the first is you)? How does he know it has 
to randomize the path? If the packet is tagged then he knows it's you the 
sender. If it is not, the best path will be chosen, which in turn might 
as well go to those nodes you're trying to avoid.
Am I missing something?

Fixed default maximum HTL is even more evil. To be more protected you must
not use that number, so you have a max HTL=24, with might not suffice for
some content.



Hmmm. Why? BTW, please don't modify the maximum HTL parameter unless you
_really_ know what you are doing, if you modify it by hand then future
increases in the default value won't be implemented by your node because
it will use the overridden value.


Why you shouldn't use 25? Because it is a flashing neon light saying it 
was me who sent that.
Why not all content will be reachable? Well, I see that for some content I 
really have to search thoroughly (more than 20HTL) before I get it.

About setting the max HTL, that is not a problem right now. I might as well 
set it to 1024, I doubt anyone will set the default that high in the near 
future :). In other words, anyone except me will clamp that value to 25 or 
whatever default it becomes, and almost nothing changes.

I argue that any default fixed value for max HTL could compromise 
anonimity. I also think max HTL should be a (partially randomized) value. 
If code for that change will be included I guess it won't matter if I have 
set my max HTL or not, since max HTL will change over requests.

Please correct me if I am wrong.
