Re: [freenet-support] some problem to install freenet on linux

Dave, after subscribing to the support mailing list, you're getting all
emails sent by all subscribers; Dennis' answer to a Linux question
wasn't directed at you.

To answer your question (even if you've been *extremely* rude to the
volunteers who run this project), please try doing the following:

1. Uninstall and reinstall Freeenet. Seriously. Please do it.
2. Before starting Freenet, open the wrapper configuration file
(wrapper\wrapper.conf in your Freenet installation directory) in
Wordpad, and find the following line:

wrapper.java.maxmemory=512

3. Change it to

wrapper.java.maxmemory=1024

4. Adjust your bandwidth settings and adjust the following sizes:

Maximum size of a RAMBucket: 4MB
Amount of RAM to dedicate to temporary buckets: 128MB
Freenet datastore size: 100GB
Maximum size of the in-memory write cache for each store: 4MB
Client cache size: 1GB

Do not change any other settings before you've run Freenet successfully
for at least a month or so, then you can start to gently tweak your
configuration further.

Finally, do not start more than ~10 downloads at once, especially if
they're for large ( 100 MB) files.

Regards,
Victor Denisov.

Re: [freenet-support] How can a system administrator detect active freenodes?

2009-08-21 Thread Victor Denisov
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

 Victor, you basically repeat my idea (about the harvester), so i will
 think about implementation. Statistics method is not an option, almost
 the same stats are shown for online games (especially real-time) that
 utilize UDP. almost constant, mostly symmetrical(not always, e.g. spring
 produces asymmetrical bursty traffic). 

I don't really think so. First, most online games are client-server, so
at each particular moment in time, it's not very likely that a
particular IP will be conversing with 15+ different game servers. Next,
Freenet nodes have random UDP ports, which is also not very typical for
online games.

Victor Denisov.

On ERROR, Freenet writes about 2-5 Kb per 10 minutes, which is really
nothing. On NORMAL, it writes up to 5 Mb per 10 minutes, or ~ 8 Kb/s
(which probably translates into ~10 to 20 writes per second, considering
internal buffering and OS write-behind caching).

No, only downloads. Total queued size varied between 25 Mb and 350 Mb in
my tests (but actual total file size was often more than reported by
Freenet, as some keys stayed at 0% for the duration of the test).

Also, to clarify things, no background applications of notice (such as
other P2P apps or distributed computing clients) were running during the
test. I regularly run Azureus, eMule and I2P, but they all were stopped
for the entire duration Freenet was running, as were MySQL and MS SQL
Server instances I work on. I also tried disabling my antivirus/personal
firewall (Agnitum Outpost Security Suite), but it didn't result in a
noticeable improvement in performance.

Yes, this I understand. I was one of those complaining of Freenet using
too much RAM :-(. But, IMO, using as much memory as possible (out of the
dedicated pool) could be important for performance. For example, by
increasing buffer sizes in db4o we can possibly make flushes more
"organized", reducing disk writes substantially. I wonder if there are
ways to tune db4o performance without rewriting the code, are there any
handles to turn in the db4o config?

> I have seagate 1TB disks mirrored, may explain the difference.

Unlikely, IMO. 1 Tb drives should have better throughput, but Freenet is
definitely limited by seek times, which should be only marginally better.

I was thinking more about allocation/invocation counts, available in
both profilers. Perhaps some method/query is being called unexpectedly
often, or a certain object is being persisted too often, etc. Also, it
could be that a certain method blocks too often and for too much time in
Windows, leading to poor I/O performance. But it's a long shot, this I
agree with.

I think that using a database is a good idea (although I personally
would've opted for a relational database such as Derby). So I'd prefer
to try and understand and fix the issue rather than hiding from it :-).

The problem's that Freenet *doesn't* even use the amount of memory I
provide it with (I'm yet to see it use more than 120 megs out of 320 I
allow for the heap). I'd be willing to dedicate as much memory as
required if only it'd help.

My hard drives are nothing special - 250Gb 7200 RPM Seagate ones, 16 Mb
cache, SATA2, no NCQ - though definitely not the slowest out there. I
see ~35 Mb/s read speed and ~28 Mb/s write speed for medium-sized files
and ~5 Mb/s to 8 Mb/s for small files in the tests I'd done. I'll
probably have to test the same from inside Java to make absolutely sure
that it's not some weird JVM issue on my platform, though.

I don't have Freenet running right now, will check it later. But I2P is
using 2670 handles right now, and Azureus uses 1450 - so 2600 for
Freenet is definitely nothing out of the ordinary on Windows. Oh, and
the highest handle user on my machine is MySQL, which uses ~69000
handles and works absolutely fine :-).

My thinking exactly. Would providing you with a snapshot of CPU/memory
performance under YourKit Profiler (I have academic licenses for both
7.5 and 8.0, IIRC) or VisualVM (which is now a part of the JDK

 Well, a major objective of the db4o rewrite was precisely this. And I don't

increasing buffer sizes in db4o we can possibly make flushes more
organized, reducing disk writes substantially. I wonder if there are
ways to tune db4o performance without rewriting the code, are there any
handles to turn in the db4o config?

 I have seagate 1TB disks mirrored, may explain the difference.

Unlikely, IMO. 1 Tb drives should have better throughput, but Freenet is
definitely limited by seek times, which should be only marginally better.

 My thinking exactly. Would providing you with a snapshot of CPU/memory
 performance under YourKit Profiler (I have academic licenses for both
 7.5 and 8.0, IIRC) or VisualVM (which is now a part of the JDK
 distributive) on my machine help? Any logging I can turn on to help?
 BTW, I have logging set to ERROR for now, as with NORMAL level it logs
 ~2Mb per minute, adding noticeably to overall disk contention.
 
 No, because it's an I/O problem, not a CPU/memory problem!

I was thinking more about allocation/invocation counts, available in
both profilers. Perhaps some method/query is being called unexpectedly
often, or a certain object is being persisted too often, etc. Also, it
could be that a certain method blocks too often and for too much time in
Windows, leading to poor I/O performance. But it's a long shot, this I
agree with.

 Do you have uploads queued as well as downloads? Generally uploads cost a bit 
 more than downloads do with db4o...

No, only downloads. Total queued size varied between 25 Mb and 350 Mb in
my tests (but actual total file size was often more than reported by
Freenet, as some keys stayed at 0% for the duration of the test).

Also, to clarify things, no background applications of notice (such as
other P2P apps or distributed computing clients) were running during the
test. I regularly run Azureus, eMule and I2P, but they all were stopped
for the entire duration Freenet was running, as were MySQL and MS SQL
Server instances I work on. I also tried disabling my antivirus/personal
firewall (Agnitum Outpost Security Suite), but it didn't result in a
noticeable improvement in performance.

 Maybe turning off logging helps? Does Juiceman also have logging
 enabled? This appears to only affect Microsoft users?

On ERROR, Freenet writes about 2-5 Kb per 10 minutes, which is really
nothing. On NORMAL, it writes up to 5 Mb per 10 minutes, or ~ 8 Kb/s
(which probably translates into ~10 to 20 writes per second, considering
internal buffering and OS write-behind caching).

2009-05-06 Thread Victor Denisov
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

 One other thing, for both you and Juiceman:
 How's the CPU usage? Given how much RAM you have I would expect node.db4o to 
 be cached in memory (how big is it?). But doing a read through the OS to the 
 OS disk cache may cost a lot of CPU (context switch etc) ... Is there a lot 
 of CPU usage for the freenet process? To the point that it might be the cause 
 of the poor overall system performance? And how much CPU usage is system?

node.db4o is ~ 25 Mb right now, with, IIRC, ~40 downloads queued, but
not many actually progressing. CPU usage for the Freenet process is
relatively low (I'd say on order of 10-15%). I'll try and see how much
kernel time Freenet uses (will have to learn how to check this), but
kernel CPU load (something which is easily checked out from Task
Manager) is about half the total CPU load when Freenet is running. Note
that firewall contributes to this number, as its driver runs in kernel
space, obviously.

I don't think 2500 handles is something unusual. I'm too lazy to check
what Freenet is holding, but my guess would be that most of them are
file handles for various files opened by both Freenet and JVM itself.

[freenet-support] Is it my system, or had builds 1208-1209 have severe performance issues?

2009-05-05 Thread Victor Denisov
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hello,

Since my node autoupdated to 1208, my system's performance degraded so
much as to render it completely unusable while Freenet is running. I
can't perform simplest tasks, such as surfing or typing a document, as
switching between tabs in Opera can take 10+ seconds and delay between
typing a letter and it showing up in Word can be several seconds as
well. Anything more stressing (such as running a game or developing an
application) is simply not possible.

- From what I can see, the reason for this is that Freenet makes hundreds
of small disk i/o ops per second, basically blocking the OS from
accessing the hard drive for swapping and such.

The above is definitely affected by the queue size. First, I tried
adding ~ 100 random files from Thaw when the node first updated, but
hadn't had the patience to wait for the request to complete (I think I
waited at least 20 minutes, perhaps more - with the system being nearly
paralyzed by the constant HDD thrashing). With just 3 or 4 files being
put in the queue the system starts to stutter noticeably, provided that
files start downloading and not hang at 0%. The only time when I can run
Freenet as a real background app is when I don't have any files in the
queue and FMS isn't running (which seems more or less pointless to me :-().

My system is set up as follows:

AMD Athlon 64 X2 6000+
4 Gb RAM
2x250 Gb 7200 rpm SATA2 HDD (mirror via mobo's built-in nVidia 570 RAID
controller)
Windows XP x64
Java 1.6.0_07 64-bit
Of course, all the latest updates/patches/drivers, etc.
Freenet uses 5 Gb datastore on an unencrypted partition.

Interesting thing I noticed was that Freenet significantly underutilized
the memory I provide it with. From 320 Mb heap memory available, I
hadn't seen it allocate more than ~ 80 Mb.

Any thoughts on why this could be happening? I hadn't seen anyone
complain about the performance of 1208/09 yet, so it is probably
something with my machine :-(, but it beats me what it could be :-(.

Victor Denisov.

Removing the file, restarting the node and then readding the file
doesn't solve the problem. I either get an error outright or, sometimes,
the file remains stuck at 100% without ever being complete (waited for a
couple of hours for a really small (like, 250 Kb) file). Simply
restarting the node is not enough to fix both problems - the error
persists after restart.

Can't say I'd seen any definite correlation - but it *seems* to affect
smaller files more often (or maybe it's just that I download smaller
files more often? can't say for sure). I'll try to take notes next time
it happens.

Also, could it be related to the latest problems with last block
padding/encoding that were announced on the lists? I don't know in what
particular point in file the files I'm downloading were inserted, and
I'm afraid I won't be able to find it out.

Yes, that's how it was in earlier versions - never had problems with
downloads being restarted in a reasonable time. Also, do my queue
downloads go into the store or into the cache? If it's the latter
(that's what I'd always assumed!), then churn could be ruled out - I
never had more than 1 Gb of queued downloads, while the cache size is
2.34 Gb, according to the stats page. The percentage was bold, so it was
 final, I'm absolutely sure of it.

Well, it's not something to loose sleep over. If db4o branch would fix
the problem, then it seems to be a good idea to concentrate on that.

1. Recently I started getting the following errors when downloads were

Temporary files error: File already freed

Freenet allows to remove or restart the download. If I restart it, it
immediately fails again with the same error. Restarting the client
doesn't seem to help.

2. For a couple of weeks at least I'm getting weird downloads behavior
when restarting the node. I have about 1 Gb of downloads queued, with
store size set to 5 Gb (so the cache should be 2.5 Gb). My understanding
was that after restarting the node, downloads would be pseudo-resumed by
trying to pull the blocks from the cache before trying to get the from
the network. However, most downloads on queue loose significant amount
of progress (sometimes dropping from 80% to 3% for a 60 Mb file) after
restarting the node (within more than an hour after restart).

trying to pull the blocks from the cache before trying to get the from
the network. However, most downloads on queue loose significant amount
of progress (sometimes dropping from 80% to 3% for a 60 Mb file) after
restarting the node (within more than an hour after restart).

Running 1192 on Java 1.6.0_06 64-bit, Windows XP x64.

[freenet-support] Some downloads failing since updating to 1178

2008-11-15 Thread Victor Denisov
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Several downloads from my download queue failed to start after my node
autoupgraded to 1178 (some *did* restart normally). Error messages
(Reason column in the "Failed downloads") in the web interface vary:

Temporary files error: invalid stored block lengths 
Temporary files error: Corrupt GZIP trailer
Temporary files error: invalid literal/length code
Temporary files error: invalid distance code
Temporary files error: invalid block type

The node gives me two options: Remove and Restart. If I click on
restart, the item fails almost immediately with the same error it had
before.

I've migrated to salted-hash store when 1175 went out. I tried
restarting the node again and cleaning up ./tmp - not helped any. I have
plenty of disk space. Log files don't seem to contain anything related
to the issue I'm experiencing.

[freenet-support] installation into a decrypted container

I guess that this happens because DriveCrypt hadn't finished mounting

running Freenet on an encrypted volume (using TrueCrypt) I had to set
its start mode to manual, so that it won't be started before I had the

[freenet-support] Global download queue logic?

| Possibly a bug - when you visit them in fproxy, the node should
immediately
| pass them along to the waiting clients.

Is there anything I can do to help troubleshoot this problem? Also, I
feel there are two independent problems here:

- - files being retrieved by Fproxy not made available to other clients in
a reasonable time;
- - files not being completely downloaded by the queue manager in about 5
days, then successfully retrieved by Fproxy in a matter of seconds;

Is there anything I can do to help troubleshoot this?

Also, I think there's a definite lack of information on the queue page
(see below).

|> Is that an expected behavior? How does the node choose what block of

|
| No, it should round-robin between them.. if it's tried them lots of
times and

| attempted for ages.

Hmm. Interesting. All files were at "low" priority, set by default by
Thaw. Is that ok, or should I set default priority to be higher?

To better understand how the queue fares, I think the following
information would be helpful:

- - average availability of each queue item (total number of blocks
retrieved divided by the total number of block retrieval attempts);
- - total number of download attempts for the item;
- - items which are being retrieved right now;
- - timestamps related to the item (entered queue, first successful block,
last successful block, last retrieval attempt);

Perhaps, in "simple" mode, the above can be summed into a generalized
"availability" metric (i.e., "good", "average", "poor", "unretrievable").

Is there a way to gather such information post mortem, from the log
files? Should I increase logging level to achieve this?
If not, perhaps I can try and see if I'll be able to understand how the
queue manager works, to add this functionality - where should I start
looking?

Victor Denisov.

[freenet-support] Global download queue logic?

2008-01-09 Thread Victor Denisov
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I've been trying Freenet for the last couple of days. It works more or
less as I've expected, but one thing really bothers me. I've got a
couple of files on my download queue, with several large files (about 50
- - 200 Mb), and some small files (about 150-200 Kb - JPEG pictures),
about 200 files total.

I can retrieve most pictures on the queue through Fproxy, and they
usually took no more than 10-15 seconds to show up. However, those same
files sit in the queue for more than 5 days (the node was up almost
24x7, save for reboots and just a couple of hours of outage), with
various degrees of progression (mostly, 50-70%). Some hadn't been
touched at all, it seems (they're completely gray, with italicized 0%
progress).

Is that an expected behavior? How does the node choose what block of
what file to download next? Does it try local cache first? Could it be
that large files (with lots of blocks) choke small files?

Its simple. JVM reports amount of memory allocated to your application
heap (this is the memory used for for objects that your application
creates). JVM also requests from the system certain additional memory to
manage its internal structures - hence the difference.

Actually, I *do* recommend uninstalling ZoneAlarm, _especially_ if
you're using eMule. ZoneAlarm has _tremendous_ memory leaks when
processing UDP traffic, and eMule uses it a lot. Either disable UDP
completely in eMule or (preferably) change your personal firewall for
something more dependable (such as Outpost Firewall Pro). BTW, the same
will apply to Freenet 0.7, and applies to I2P now. I have one box where
I can't uninstall ZA for reasons outside of my control - so I have to
stop/start ZA service there about every 2-3 days when using I2P, and
even then the system has to be rebooted about once a week.

Re: [freenet-support] Installation Issues

2005-01-30 Thread Victor Denisov
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hello,

 XP Home behind a firewall.

What sort of firewall? Windows' built-in, some thrird-party one (such as
 ZoneAlarm, etc) or external firewall?

 I tried installing from a limited user account to my user folder. However, I 
 kept getting
 Download of nodeconfig [or any other file for that matter] failed: Retry?. 
 Seeing as how this 
 is the installation itself, I cannot play around with any settings to fix 
 this issue. Why do you

You can always install Freenet by hand - its not that difficult.
However, I beleive there should be an easier solution.

 need an internet connection to install the program? Why not just bundle the 
 files required? 

Two reasons. First of all, information about the nodes you can connect
to initially (they're called seed nodes, hence the seednodes file) is
very dynamic, so it has to be fetched from the Freenet project website
on install. And second, Freenet node versions sometimes change very
frequently, so this procedure makes sure you always get the latest version.

 As it now stands, I cannot install Freenet's software to my computer.

Let's see if we'll be able to help ;-).

 I have also tried installing under the admin account.
 
 If it's the firewall, then WHY does the software need ports forwarded just to 
 install?!?!

It doesn't. All downloads are over regular HTTP. Check that you can
download files from Freenet website through your browser (try
http://www.freenetproject.org/snapshots/NodeConfig.exe). If you can't,
then it couldn't be connected to the installer. If you can, then you'll
likely have to download and install Freenet by hand.

Also, I've found from experience that sometimes Freenet project's site
is somewhat slow in responding, and it confuses the installer - maybe
there's some sort of too short a timeout somewhere in the download
code... So, if you're sure you can download files from Freenet website,
you can try to install Freenet several times over the course of about a
day - sometimes it does help.

Victor Denisov.

Re: [freenet-support] Freenet on NetBSD 1.6 (old java version)

2004-05-28 Thread Victor Denisov
Unfortunately, Freenet requires Java 1.4.x JVM, because it relies on nio
(non-blocking input/output) API only available in 1.4.x. For the same
reason, Freenet can't be run under open-source JVMs - Classpath's nio
implementation is buggy (this _should_ change in the near future).

Also, 1.4.0 had some known nio problems, so its not recommended as well.

Subject: [freenet-support] Freenet on NetBSD 1.6 (old java version)



 Hi.

 I recently got my broadband connection, and of course I want to run
 Freenet, but I ran into some problems.

 Summary:

 I have/run NetBSD 1.6.

 There is a sun-java 1.4 package, but it will only install under
 NetBSD-current.

 Freenet doesn't seem to like 1.3.1.10.

 Sun java detected.
 1.3.1_10
 Old version of java detected.
 Please install a 1.4.x JVM.


 So, it seems my options are:

 1. Upgrade to NetBSD-current (but I really prefer the release versions)

 2. Wait for NetBSD 2.0 (any time now..) and hope 1.4* will work.

 3. Try to get 1.4 to install on NetBSD-1.6 (Lots of work, probably)

 ..unless Freenet can run on a 1.3 JVM.  Can it?

 The project main webpage says We have experienced best results with
 Sun's Java Runtime Environment (versions 1.4.1 and later), which would
 seem to indicate that Sun's Java Runtime Environment (versions 1.4.1 and
 later) is not an absolute requirement.  But I doubt I'd be *that*

Re: [freenet-support] Interesting observations regarding performance

2004-02-18 Thread Victor Denisov
 I've run Freenet on a Duron 900 with 512Mb ram, Windows 2000, for quite
 some time. The javaw process has consumed all available CPU, and the
 computer has been quite sluggish due to Freenet. I've also seen very low
 transfer speeds in FUQID (easiest to measure with, I think) - around
 1-2kb/s when content is found.

 A few days ago I got a new system - a P4 3.2GHz, 1024Mb ram, still Windows
 2000. Freenet now consumes around 0-1% CPU-time, it has no negative effect
 whatsoever on the performance of the rest of the system, and transfer
 speeds are up to 11kb/s.

 The Freenet node and contents are the same, I moved system behind my NAT
 so the Freenet network knows nothing of my change - it's all internal.

 I find the above very interesting .. comments from others?

The most likely reason is that Duron (as well as Celeron) lacks enough L2
cache to effectively cache interpreted (or semi-interpreted) code, such as
Java, Perl or PHP. For our serverside Java applications (which, admittedly,
load CPU much higher than Freenet does) difference with Duron and Athlon is
about 2x-4x at the same clock speed. We have no benchmarks for our GUI, but
I've made one w/ Sun Forte for Java about 2-3 years ago. On the same machine
equipped with Celeron 400 MHz (128 Kb L2 Cache) and PII-400 (512 Kb L2
cache), 128 Mb of RAM, Forte loaded in about 8 mins w/ Celeron, less than 3
minutes w/ full PII.

Of course, Java went quite far in the past couple of years, but I still
doubt it can fit in small amount of L2 cache available on modern low-end
CPUs.

Re: [freenet-support] Re: routing table

2004-02-18 Thread Victor Denisov
 Well there are Countrys where bandwidth is very cheap or free for home
users
 while memory is really expensive. For around 10$ per month I get unlimited
 bandwitdh on my adsl line. Take a look at the attached Image to see how
cheap
 brand memory can be (noname memory isn't a subject cause it is a shure way
 to make your system unstable). This is one of the most expensive here, but
it
 is still a quite good example for way higher prices in different countrys.

Wow!!! Man, how do you use computers at all with such prices for brand
memory? I've just checked - retail Kingston 256 Mb PC133 module costs
$38-$45 here in Russia, and we consider our computer parts market to be
quite expensive compared to western one.

On the other hand, our broadband access is really expensive - the best you
can have here in Moscow is either 7500/768 with 5 Gb traffic limit (and
$10/Gb over the limit) or 128/64 unlimited, both for $99/month.

Re: [freenet-support] routing table

2004-02-13 Thread Victor Denisov
Title: Message



Freeing up RAM is not related to routing table at 
all. Unfortunately, Freenet code contains a bug (a so called "memory leak") 
which takes memory from your OS, but then "forgets" about it, not using it and 
not returning it - so the amount of memory used by your node grows constantly, 
until you start getting Out Of Memory errors (or OOMs for short).

So far, attempts by developers to catchthis 
particular bugweren't successful. The only 
advice I can give is to restart a node once in a while (every 6 to 12 hours 
seems to be a good choice).

[freenet-support] 5046 fails to integrate?

2003-12-02 Thread Victor Denisov
Hello,

For a few days, something strange goes one with my new stable node. It seems
that it is unable to integrate into the network. Look at this:

1. Histogram of node versions in fred's Routing table:

Fred,0.5,1.47,5036 |=
Fred,0.5,1.47,5039 |=
Fred,0.5,1.47,5041 |===
Fred,0.5,1.47,5042 |=
Fred,0.5,1.47,5043 |===
Fred,0.5,1.48,5046 |=
Fred,0.6,1.47,6356 |=
Fred,0.6,1.47,6359 |=
Fred,0.6,1.47,6364 |=
Fred,0.6,1.47,6367 |=

Ok, the majority of nodes is from the same stable branch. This was taken
from a seednodes.ref approximately 2 days ago.

2. Uptime:   0 days,   4 hours,   9 minutes

The node's been up for 4 hours - but it was up for at least 12 hrs before
that, I just had to restart the server it was running on.

3. In the routing table, only about 12 nodes have CP  0.01. However, it
fails to purge those bad entries or acquire more nodes instead of them.

4. Probability of success of an incoming request: Max: 0.006535948.

Hmmm - much worse than 0.02 I came to expect from NGR-stable.

5.Inbound Requests
# unique hosts: 1
# format: requests requests accepted successful requests address
version
#
2316 2316 1 218.186.51.225 Fred,0.5,1.48,5046

What gives? Only one node had tried to route requests at me?

6. Global network load stats

# Tue Dec 02 18:39:54 MSK 2003
# entries: 100
# mean globalRequestsPerHourPerNode: 21604.729411764707
# median globalRequestsPerHourPerNode: 11337.0
# standard deviation globalRequestsPerHourPerNode: 26710.243786388233
# smoothed localRequestsPerHour: 775.662308458498
# smoothing half life (hours): 1.2
# instantaneous localRequestsPerHour: 486.6695794742238
# The last 500 queries arrived in 3698.608 seconds.
# Current proportion of requests being accepted: 0.784
# Current advertise probability: 0.29619676669542405

Again, hmm. Not that my node is overloaded (it can handle ~2-4 qph easily,
at least, w/ NGR). And it has a decent advertise probability.

So, why no one talks to me, just a single lousy node? What should I do?

With best regards,
Victor Denisov.

Re: [freenet-support] 5032 FIW 0.07 - FEC Encoding problem?

2003-11-20 Thread Victor Denisov
Hmmm. Strange. This was the first thing I've thought, so I've tried setting

luck, the error still happens.

Subject: Re: [freenet-support] 5032  FIW 0.07 - FEC Encoding problem?


 this is a FIW issue which is known for some time now but has never been
fixed

 FIW sets the socket timeout for FCP connections to 5 minutes.
 if a FCP connection is more than 5 minutes in use, FIW closes it therefore
and throws an SocketTimepoutException (well, java itself does it, but
nevertheless the connection gets closed and an exception is raised)
 so any action which uses more than 5 minutes to complete is unable to
succeed!
 as FEC encoding may take up to half an hour or more depending on your
machine power and the size of your splitfile, you are unable to upload the
file as FIW fucks up with its default settings

 you might consider changing the
 tuning.sotimeout=30
 parameter in fiw.conf to something higher (30 milliseconds = 5*60*1000
ms = 5 minutes), or to 0 to disable the timeout

 HTH

 When I'm trying to upload a site containing a large file (~ 150 Mb) with
FIW
 0.07, I get the following error message in FIW when generating FEC check
 chunks:

[freenet-support] Re: Freenet port usage

2003-02-03 Thread Victor Denisov
Hmm, still hadn't received a reply through a mailing list, so I'm answering
by looking at the archive.

Of course, all outgoing ports are open for an IP address that Freenet is
bound to. The problem is that Freenet seems to listen for _incoming_
connections on absolutely random ports. I recall reading somewhere that this
is a feature -Fred contacts another Freenet node with request for data then
drops TCP connection and waits for incoming one from that node, so as to
conserve TCP connections during long data searches and limit amount of
traffic and resources required for maintenance of idle connections.

This seems wise, but only in case if a single port (or a known range of
ports) is used to handle such incoming connections. Basic security dictates
that _all_ ports which aren't in definite use should be closed, and if this
rule can't be followed with current Freenet operation, I'm afraid it could
be a real security problem for all more or less secure environments.

That's why I've asked if a knows range of ports exists for Freenet. I know
Java a little bit, but I don't think I'll brave the code myself to find out
exact port ranges (or if they're defined at all). If they aren't defined,
maybe it would be possible to consider to make such an option?

With best regards,
Victor Denisov.

[freenet-support] Re: Freenet port usage

2003-02-03 Thread Victor Denisov
I'm sorry, I'm still to receive a single message from support mailing
list... To continue discussion:

---
 Of course, all outgoing ports are open for an IP address that Freenet is
 bound to. The problem is that Freenet seems to listen for _incoming_
 connections on absolutely random ports. I recall reading somewhere that

The port is selected randomly when you configure freenet for the first time
and can be found in freenet.conf or freenet.ini. IIRC, it's 'listenPort',
but
I'm not sure.
---

[VD] That wasn't what I was trying to convey. Of course, FNP port, as
defined by listenPort in freenet.ini, is open for incoming connections, and
I see it as LISTENING as well. I also periodically see connections
established at this port, so things are working as expected.

In my case, Freenet creates a bunch of listening ports _in addition_ to FNP,
Fproxy and other listed ports.


Yes, there's a line in the config file:
# The port to listen for incoming FNP (Freenet Node Protocol) connections
on.
listenPort=XYZ

It's a randomly chosen port by the setup or by the generation of the config
file.
This port is usually between 1024 and 65535, the node announce itself ONLY
with the current IP address and the chosen FNP port. (that's a node
reference,
look in the seednodes.ref-file)
---

[VD] Yes, of course, this port is open for incoming connections. That's what
the Freenet docs (however sparse) imply.


Other nodes only tries to connect on the FNP-port.
I see also a lot of listening ports between 1025 and 4500, but I don't know
the
reason. (see the attached text file)
-

[VD] I reckon these are ports opened by your node to wait when nodes it
contacted will call it back with response to the query it sent into the
network.

-
Client programs uses only 8481 for the Freenet Client Protocol (FCP),
 for the browser (-mainport) and 8891 for the distribution node (if
not deactivated).
-

[VD] Absolutely correct.

-
 this is a feature -Fred contacts another Freenet node with request for
data
 then drops TCP connection and waits for incoming one from that node, so
as
 to conserve TCP connections during long data searches and limit amount of
 traffic and resources required for maintenance of idle connections.

 This seems wise, but only in case if a single port (or a known range of
 ports) is used to handle such incoming connections. Basic security
dictates
 that _all_ ports which aren't in definite use should be closed, and if
this
 rule can't be followed with current Freenet operation, I'm afraid it
could
 be a real security problem for all more or less secure environments.

This situation IS a security problem. But read Freenet's port usage in my
answer above. You only need to forward the FNP port to the Freenet node.
-

[VD] Hmm, my experimental evidence seems to contradict your point. First,
strange ports you've listed (as well as those on my machine) are owned by
javaw.exe, and Freenet happens to be the only java app on this machine. And
second, when I block all ports, except defined ones, my Freenet performance
degrades rapidly, with node coming to a halt with RNFs 95% of the time -
this is an indication that there's a problem with request propagation in
such configuration. Things get back to normal as soon as I allow all
incoming connections again. So, allowing (or forwarding) only FNP port isn't
enough :-(.

I know how real developers despise support lists, but I hope that someone
with code knowledge will be able to prove or disprove my point, or at least
will point to a correct place to look in the source. I don't want to barge
into devl, since I don't think this beleives there.

If, indeed, Freenet opens one listening socket for each node it contacts
(or, God forbid, for each request it makes - but this isn't likely, judging
by the number of open sockets I see when loading TFE), I'd like to hear if
this is under consideration for modification in future versions.

Victor Denisov.

I have the same problem. Do you use localized Windows version? What exactly?
What browser? I use Windows 2000 Russian, I've tried both English and
International Java JRE with no success. I guess this has something to do
with these strange Europeans using their strange character set (ISO-8859-1)
on their workstations ;-)... Please set your log level to Debug and try
accessing the gateway again, then send your logfile (ZIP compressed!) to the

One thing I was thinking about is if the recompiling of the source on my

[freenet-support] Unsubscribe test results

2002-09-24 Thread Victor Denisov

I'm subscribed to this list as [EMAIL PROTECTED] I also use Hotmail
account [EMAIL PROTECTED] To check if unsubscribe works or not,
I've done the following:

Software: Windows 98SE, Internet Explorer 6, Outlook Express 6.

1. Went to http://hawk.freenetproject.org/mailman/listinfo/support/.
2. Entered e-mail [EMAIL PROTECTED], password 12345678 (no, that's
not the password for Hotmail account ;-)).
3. Received e-mail from [EMAIL PROTECTED] with subject
support -- confirmation of subscription -- request 792232
4. Replied to this message, keeping subject line intact.
5. Received another message from [EMAIL PROTECTED], with
subject being Welcome to the support mailing list.
6. Posted test message from this account to [EMAIL PROTECTED]
7. Received this message on both [EMAIL PROTECTED] and
[EMAIL PROTECTED]
8. Went to http://hawk.freenetproject.org/cgi-bin/mailman/listinfo/support,
entered [EMAIL PROTECTED], entered 12345678 in Unsubscribing from
support - Passord field, pressed Unsubscribe button.
9. Got support Unsubscribe Results - You have been unsubscribed
confirmation in browser.
10. Posted another test message to [EMAIL PROTECTED]
11. Received this message on primary account, but not on Hotmail account.

Hope I hadn't missed anything important.

So, my conclusion is that unsubscribe function _does_ work, at least for
some list members. What I would've done is try to use different
browser/e-mail client. If this won't work, I'd try to subscribe/unsubscribe
from the same machine/software, but use a different e-mail address. If this
will work, then it is definitely a glitch in the mailing list software. This
does happen, unfortunately. Since you got no response from list admins, just
configure your client to ignore messages from this list - it's not _that_
difficult, and the traffic on the list is quite small.

BTW, this list is open to non-subscribers, so no wonder everyone can send
messages to it. AFAIU, this was a deliberate (though questionable) decision
on the part of the developers.

With best regards,
Victor Denisov, aka Larder Larder.
