Do you mean preventing other people from accessing the default

Can you paste your wrapper.log file, at least the last bits of it where
you saw that error message. How much memory do you have in your box?

Re: [freenet-support] Error messages in wrapper log

2013-02-08 Thread Dennis Nezic
I assume you mean the Database corrupted message? I wonder how
serious it is -- if freenet was able to recover from it. Can you
download files?

The generic answer to such database corruptions is to get rid of (or
move) node.db4o*, which will also get rid of your download/upload
queues.

Of course, never underestimate the brutality and inconsistency of the

For a start, you can check your wrapper.log file -- perhaps output a
thread dump when you think it's broken (via the web/fproxy interface, in
the Statistics section, Generate a Thread Dump) -- the output will
also get dumped into wrapper.log. If none of that is informative, you
can enable more detailed logging in the Logs section. Be careful to
scrub any logs[1] of sensitive information before sending them.

That's what I'm pulling my hair trying to find out! I only
upgraded a few system packages on my machine, like glib,
libffi, ... -- and nothing much else! But how can a seemingly
unrelated system package have such a huge effect in a Java
environment??

I haven't changed my jdk (although recently I did test with 
others, sun-jdk and icedtea-bin), I haven't changed my ant, I 
haven't changed my db4o's, I recompiled all of Freenet's
(direct) dependencies. This is incredibly frustrating. I mean,
1407 WAS working before, and now it's not :S.

Here are the types of AbstractMethodError's that arise:


java.lang.AbstractMethodError: 
com.db4o.internal.query.ObjectSetFacade.iterator 
()Ljava/util/Iterator;


at freenet.client.async.ClientRequestScheduler.loadKeyListeners
(ClientRequestScheduler.java:114) [code]
ObjectSetHasKeyListener results = Db4oBugs.query (container,
HasKeyListener.class); for (HasKeyListener l : results) {
--- ** 114 [/code]


java.lang.AbstractMethodError: 
com.db4o.internal.query.ObjectSetFacade.iterator

(PersistentStatsPutter.java:44) [code] 
ObjectSetBandwidthStatsContainer BSCresult =
container.query (BandwidthStatsContainer.class); for
(BandwidthStatsContainer candidate : BSCresult) {   --- **
44 [/code]

So what did you do to establish that your database is not
corrupted? These are internal db4o errors.

Hmm. So it does seem as though my datastore was corrupted.
Deleting it, and making my node create a new one got me up and
running again. Thanks Steve!

The odd thing is a bunch of us[1] have been getting this
error / corruption since about the time build1409 came out. I
sure hope it's just a freak coincidence :S.

[1] https://bugs.gentoo.org/show_bug.cgi?id=429716
   
   Your _datastore_ was corrupted, not your node.db4o(.crypt)?! What
   exactly did you do to get your node running again?
  
  Correct. The very first thing I tried (which usually worked before
  with db4o errors), was to delete my node.db4o.crypt file. That had
  no effect this time. Instead, deleting datastore/*, or starting
  with a fresh installation, with the wizard, got the node running.
  Drastic, I know. (Although, Tommy in the bug report mentioned he
  was able to reproduce the error even with a clean wizard
  installation :S.)
 
 That is not consistent with the error message you gave, which is
 clearly a db4o problem.

Are you sure about that? Is there no way a corrupt datastore could
corrupt the db4o file? What do you suppose created that db4o Abstract
Method Error? (Considering the fact that deleting it, and letting
freenet make a new one still caused it.)

That is very strange. You should be seeing an Update Now! button
right beside that message. Unless, for some strange reason, your node
isn't able to download the newer versions. What version are you
currently using? How long do you keep your node running for? -- it'll
take a few minutes to fetch it. How many peers are you connected to?


  In fact, IMHO, no. Program updating and maintaining should be your
 operating system's responsibility. But we digress.  Operating
 Systems do not update independent programmes mate!  The operating
 system provides a platform for programmes to interface with me.

I suppose technically I meant it's the distribution's responsibility --
your package manager's -- definitely not a program's, IMHO.

 
 My operating system will not update independent programmes on their
 own.

So, my implication was that you may want to consider using a better
distribution :). Just a consideration.


 The programme needs to update itself.  (My OS takes care of
 updating my Freenet node.)  How does it do that?

Easy. The same way it handles every single other program on my
computer. There is a package for the program, and a big community of
people watching out for updates and such.


  The operating system updates itself but not other programmes.  Eg
 adobe tell me there is an update, so does my media player,

So, you don't really seem to be using any package manager -- that is,
*you* are left with the tedious job of figuring out what needs updating,
and figuring out how to update each thing individually -- each of them
probably have their own quirky way of doing things, etc. This is one of
the areas where Linux (the Linux community) shines.

Nevertheless, Freenet does tell you that there is an update. And it
is /supposed/ to give you an Update Now! button. So, we have to
figure out why your node isn't downloading the newest versions. My one
does.


 freenet just says it is too old.  The operating system has nothing to
 do with it.
 
 Also the download prioritisation has disappeared in the new version I
 downloaded.  It just needs a bit of real help, it can't be that hard
 to offer help options with a warning message, after all the
 programmer has offered a dialogue box to tell us there is a problem,
 so obviously they know what that problem is.  Ergo they can offer a
 solution to the said problem.

So, regarding the updating issue, this is already supposed to happen :).

 Freenet constantly checks for updates on it's own, and notifies you

 instructions and help are appalling.  You say there is a problem, but
 never offer a solution, just some string of geek jargon that is
 meaningless to anyone who is not a programmer.  I find it easier to
 just uninstall (losing all pending downloads etc) then re-install.  I
 have not once found a solution to a problem I have had.
  
 Examples are notices saying that my node is too old and if I don't
 upgrade I will be left in the dust whatever that means.  I cannot
 update, the bloody programme is supposed to do it for me!

In fact, IMHO, no. Program updating and maintaining should be your
operating system's responsibility. But we digress.


 There is no check for updates button.

Freenet constantly checks for updates on it's own, and notifies you via
that message you mentioned above. I'm not sure if it's supposed to
auto-update on it's own, or if you have to click a button to do it
manually. (My OS takes care of updating my Freenet node.) Are you saying
you tried clicking, and it didn't work?

 Your _datastore_ was corrupted, not your node.db4o(.crypt)?! What
 exactly did you do to get your node running again?

Correct. The very first thing I tried (which usually worked before with
db4o errors), was to delete my node.db4o.crypt file. That had no effect
this time. Instead, deleting datastore/*, or starting with a fresh
installation, with the wizard, got the node running. Drastic, I know.
(Although, Tommy in the bug report mentioned he was able to reproduce
the error even with a clean wizard installation :S.)

 Do you think you could try git-bisect to determine whichcommit
 introduced this problem, or are you not able to reproduce it at will?

So far my node is running. The only way I can think of reproducing it
is by going back to the 1407 that I was using for months -- probably
recreate my datastore with it -- and then upgrade to 1409 again :S.

Nor the newer builds. Recompiling with sun-jdk and icedtea-bin doesn't
make a difference. Recompiling java-service-wrapper, all the db4o deps,
ant made no difference.

So that looks a bit suspicious to me, although I've never used the

You can try cutting out just the last part of the log, like, from the
last Launching a JVM to the end. That should be a lot shorter.

Usually the culprit is a lack of memory or disk(space). So, how has the
memory and diskspace changed after switching the hardware?

Looks like some kind of node.db4o* corruption -- another kinda common

sure if the defragmenting of it just before had anything to do with it.

The simplest solution is to delete your node.db4(.crypt?|*) file.
You'll lose the downloads/uploads that you had queued, but that should
get the node back up and running at least :s.

 Many thanks for the suggestion. I don't know what the node.db4o*

 the problem. I guess from that, it may be disk-space related after
 all. My /usr/local/freenet is a symlink to a directory on a different
 filesystem, precisely because there is not enough room on the
 'real' /usr/local drive. My understanding was that any file or
 directory created under /usr/local/freenet would actually be created
 in the directory to which the link points. Is Freenet somehow
 creating files or directories elsewhere, i.e. not
 in /usr/local/freenet?

The node.db4o files store things like your uploads/downloads -- so, you
should make a copy of the links of those things before deleting it, if
possible :p.

Regarding the disk-space, it probably is storing your node.db4o files
in the proper symlinked place, but you also have to consider
the ./persistent-* directory (and possibly the ./datastore directory if
you're resizing your datastore), cuz those can get pretty big too.

 I imagine a simple filter could be written that checks that none of

Aren't there tonnes of these kinds of bugs... ie. I don't think it's
Freenet's responsibility to manage all the other possibly bugged
packages on one's system. If anyone is using such a bugged version of
Microsoft, they'll get screwed no matter what bandaids Freenet tries to
apply.

 That sounds nice, you could make the ZI package/feed depend on JDK so 
 there were no longer any unfulfilled dependencies on the user's end 
 regardless of platform, since it would be automatically installed.  
 Instead of the existing installer, you could have some of those
 things done with a web-based first run setup wizard.  Upgrades could
 be handled by ZI updates instead of custom updaters, too.
 
 I don't know if redoing all that is worth it in exchange for certain 
 perks though, since Freenet has already implemented so many of its
 own systems to make up for not having those systems exist across
 platforms. Perhaps ZI is too late to the party. :)

It's not too late. The more packages, the more availability, the
better. I prefer using Gentoo and it's ebuilds, so ZI is mostly
irrelevant for me -- but I'm sure many people still need it.

One DIY possibility is Freenet's telnet interface with an expect
script. (man expect).

Another, probably, is via Freenet's FCP interface, possibly via netcat
(man nc) or something like that?

  Okay.  Developers would love to not have to spend the time
  making a package for every distro and distro verison though, and
  running 0launchprogram's url to download and run a program
  from the command line is an option, though not as simple, but
  hopefully after it gets a software store for ZI collections that
  will become an option as well.
  The whole point of community distros is precisely to help program
  developers in this regard. Gentoo users, for example, maintain a
  freenet package completely on their own. It seems like you're
  trying to wish away the whole concept of distros. (Actually,
  trying to impose your own preferred
  yet-another-package-manager :p.)
  Yes, everyone loves re-packaging the same program over and over and
  over again, tons of fun. :P
 
  ZI is a package manager that can run on top of or beside existing
  package managers because it allows co-existence with other package
  managers.  You can install it on any distro.  That makes it one of
  the few cross-distro and cross-platform (Mac, Windows, BSD etc too)
  package managers out there, and thus much more capable of becoming
  a real actual god-forbid Linux standard to allow users and
  developers more freedom to share programs.
 
  So, your proposition that it's useless is totally absurd.  Why
  anyone would go ye I have to make 50 billion different
  packages for the same program because there are no standards! is
  totally beyond my comprehension.  There is no actual justification
  for having multiple formats/standards/managers.  You want to
  choose one standardized system, and then throw all the features
  you need into the managers which are compatible with that system.
  [snip]
   From my perspective, it is useless. I already have a great package
  manager, and a freenet package. You also don't seem to understand
  the purpose of different linux distributions. The reason you need
  50 billion different packages for the same program, is the same
  reason 50 billion linux distros exist, and the same reason why
  having a single standard is quite naive and absurd -- people are
  different. (Decentralization and independent testing that distros
  provide are also invaluable.) (Open-source) program developers
  should not be in the business of distribution.
 
  Anywho, the point is there really should exist apt-get freenet by
  now. And 0launch freenetwhatever too :P.
 You can have different bundles of software on ISOs, and even programs 
 with different default configurations, that's good and I have no
 problem with that.

You are naively assuming the only difference between packages is
configuration files. That's simply not the case. Some people would like
to compile packages to minimize size. Other people to maximize speed.
Still other people for other special reasons. Believe it or not, things
are the way they currently are for valid reasons.

 That has no bearing whatsoever though on having a standardized
 package management solution.

In terms of practical importance, standardized packages are waay down on
the priority list. The reason a debian freenet package doesn't yet exist
has very little to do

What bothers me is how it was running for a couple years without

things should work like before?

 Here is my wrapper log:
 
 http://dl.dropbox.com/u/5177370/user1-wrapper.log.zip
 
 Wonder if my hardware is too light for freenet server use now?

Hmm, okay, I guess that wasn't too helpful :p. But, many clues can be
gleaned nevertheless. The first hang was caused by Resizing
datastore, although I'm not sure if it was due to insufficient memory,
or I/O bottleneck. (Perhaps you can monitor your free memory and
uptime values next time.) After that first hang, it looks like your
node wasn't even able to restart itself -- it could be a wrapper
problem, or perhaps a node bug caused by the original failed
datastore-resizing attempt. Magically, 8 hours later, it does manage to
restart, but 15 minutes in, it hangs again during datastore maintenance
-- again, probably due to insufficient memory.

You said you reduced memory from 512mb to 256mb -- put it back to
512, if you can :p.

Alternatively, you can test with a fresh/new datastore, to avoid
resizing overhead, which I believe is costly?

 I would put money on them taking advantage of zero day exploits

 that appeared to be a fairly low-value target. The only thing that
 might stop this from happening to other projects is where the
 developers are operating in one country and the government attempting
 to force the change is in another.

Another thing that might stop this from happening is open source

before it gets released. (I'm actually not sure how many coders have to
currently sign -- surely it's not just Toad?)

Do you have a link or more info on that German case? Was it open-source

kind of backwards legal mechanism to force him? I wonder how much I can

 This is why you have authentication and checks against any inability
 to connect to nodes.

There is no such authentication that would help here. And you would be
able to connect to any node normally -- except the compromised nodes
would still find a way to become your peers and surround you. (I'm not

a stranger's offer, but I'm sure a dedicated adversary can easily meet
them.)

 You are looking at the issue wrong. It doesn't matter which nodes are
 bugged. If a user can't connect to higher than normal percentage of
 nodes it should send up a red flag for one.

They will be able to.

 You can keep track of nodes as well and check out which nodes are new
 and which have been added over time. The number of new nodes coming
 online shouldn't exceed a certain threshold. If there are 5,000 and
 on average the number of nodes increase by 2 a week then 100 new
 nodes coming online should send up a red flag. I don't know what the
 actual numbers are or the range. Maybe some weeks do see 100 nodes
 and others only 2. There is probably a number though that could
 increase the time it takes to pull off such an attack.

There is no such metric -- a slashdot article, for example, could
easily trigger such a gauge. Moreover, you're not understanding the
attack enough -- the bad guys don't need to control too many bugged
nodes -- just a few which they will find a way to peer with you.

By the way, here is one freesite that tries to measure how many nodes

 I think the best way to organize a revolt or guerrilla war fare in

masses -- the majorities. If you don't have popular support, you're
doomed no matter what you try to do. The best way to organize a revolt

 I think you are wrong here. I think authentication could work to a
 degree provided certain conditions are true/consistent enough. I am
 assuming certain things such as there being enough nodes that come
 online daily and stay online permanently. It may not work if the
 number of nodes which come online and then go offline is high. I'm no
 expert here although in theory you should be able to use
 authentication to verify that old nodes are still under the control
 of the person they were under prior. Chances are the initial nodes
 you trust aren't going to be compromised by your adversary.

First of all, on opennet, the peers you are connected to change every
few minutes/hours. They are not static. They constantly change to make
routing more efficient, via swapping. I was not suggesting the bad
guys actually compromise other people's nodes -- the far easier and
more likely scenario is they simply have *their own bugged nodes*, and
try to become your peer. (And I think, (not absolutely sure), for a
dedicated attacker, this is pretty easy.)


 The adversary would have to slowly bring on new nodes then and would
 be limited to a particular number of nodes per day (however many is
 typical). If they try bringing on too many new nodes at once an alert
 should go up.

So, again, *their nodes* (just a few... 10-20?) will initiate peering
with your node. And there is nothing you or anyone can do about it.
This is the problem with connecting to strangers -- ie. opennet.

Although, I guess this can be (already is?) mitigated somewhat if we
only allow a certain percentage of our peers to come from external
(swap, etc) requests -- but then it would simply become a question of
time before you initiate peering with their nodes -- and they will have
many, including big and popular seednodes.


 For instance say there are 5000 nodes already, and there are never
 more than 20 new nodes that come on per day then the adversary would
 need 8 months to add 5000 nodes. If they brought on 40 nodes a day it
 would be apparent that an attack was underway.

How would you tell the difference between freenet becoming more
popular, and the bad guys slowly infiltrating the opennet? Also, you
assume they only have a few days to perform the attack -- how do you
know most of the current nodes aren't them right now?


 The way to do this really is to monitor the data and figure out what
 the statistics are or have been over time and then base it off this
 information. If there is a change in those statistics it could
 indicate an attack.

This is being done. But it won't help in this case at all. (Even if I
wanted to dump thousands of bugged nodes into the network, I could
simply post a Slashdot article, and join that upsurge.)


  You are looking at the issue wrong. It doesn't matter which nodes
  are bugged. If a user can't connect to higher than normal
  percentage of nodes it should send up a red flag for one.
 
  They will be able to.
 
 They will be able to what?

They will be able to connect to normal nodes too. Of course, from your
perspective, they're *all* equal strangers. (On opennet.)


  I don't doubt that some developers think opennet mode is hopelessly
  insecure.
 
  It's not that they think it's hopelessly insecure. It really
  is :p. I mean, it might still be good enough -- but there are
  actual, well-known, unsolvable problems with the opennet idea.
  Which that FAQ should have explained :p.
 
 I'm not arguing it is or isn't. Everything is relative though.

No, everything is not relative :P. Opennet *is* pretty easily
exploitable by design. This isn't a problem with freenet in particular
-- but of any untrustworthy network. (Opennet does actually have a
minimal amount of trust in it -- via the seednodes. But it's easily

 I was not referring to zero day exploits actually. The key word here
 was local real-world threats. Such as an adversary gaining physical
 access to the server/machine running freenode.

If the bad guys have physical access, and care, it's game over.

I suppose you can try setting secret tripwires that might notify you
if the machine was tampered with (both in software, and in hardware.)
Those might give you a fighting chance. Although you'll also need to
make sure your room wasn't bugged with pin-hole cameras and other
spy-ware. It's a lost battle, regardless.

 Removable media may not eliminate the threat although there is less
 opertunity for a more sophisticated targeted attack. A software
 keylogger inserted into the MBR or similar would not be possible if
 the boot medium is never available to the attacker.

But it will be available if you ever decide to boot, happily recording
everything. Again, if you think your machine was actually tampered
with, you should assume it's unusable.

 On the other hand a physical keylogger may still be possible and maybe
 even a software based keylogger although more difficult to
 disguise/install without being noticed.

Of course. You should expect a variety of key loggers installed, in
code, under your keyboard keys, acoustic key loggers stuck somewhere
inside the machine (that can acoustically determine which key you're
pressing), and a bunch throughout your room in pin holes in your walls
and ceiling.

 I can think of at least a few different ways of getting a keylogger
 onto a system without having access to the boot drive or having to
 install a physical device. I would still need physical access to the
 computer. At least one method would not even require BIOS
 modification and would work on any x86 machine.

So you're already aware that there is not much hope if the bad guys get
physical access? :p

 [...]
 Lets give a scenario:
 
 We have to assume that a persons Internet connection is being
 monitored. This might be via a sophisticated non-governmental actor
 (such as by breaking WEP/WPA) or by a government act such as
 monitoring at the telco. The adversary should also be assumed to be
 unethical in that there are no rules

In that case, if you're using only opennet-mode, you should assume
you're screwed :p. They can replace all your opennet peered nodes, and
see exactly what you're doing, more or less. This is why darknet-mode
was created -- they would need to physically infiltrate all your
friend's computers, which isn't impossible, but MUCH more difficult.

 and can physically modify or otherwise install a software based
 monitoring solution on any boot media they have access to.

Then you're *definitely* screwed, regardless, as explained above.


 The first question is how many peers need to be compromised to
 identify the content being transmitted?

All of them, to be 100% sure. Compromising opennet peers is trivial --
with a dedicated-enough adversary. Compromising darknet is a lot
harder.


 If a few of your freenode peers can be compromised and the adversary
 can monitor your Internet connection and local area network can they
 identify the contents which are being requested/sent by you? This
 assumes that they can't bug the physical machine that you are using
 to run freenode.

As long as you still have one uncompromised peer, I guess they can't be
sure what traffic you're generating locally, and what you're simply
relaying for that peer (or that peer's peers, etc). But if they're able
to compromise all-but-one of your peers, it's pretty darn close to
game-over :p. If I was an unethical bad guy, I'd arrest you and that
peer, separate you into isolation-cells, and play psychological games
until one of you confesses. Or perhaps torture. (Although, if that
other peer doesn't have anything to hide, or isn't your friend, I'd
easily jump to the conclusion that you're the one I'm looking for :).


 If you add a server with freenode (which can be bugged) to your local
 LAN that is then added as one of your peers does this compromise the
 security? The point of adding a server with freenode to peer with on
 the local LAN would be to speed up requests since the machine that is
 actually used for browsing freesites (such as a laptop) can't be left
 on all the time (as doing so gives an adversary opportunity to bug
 it). This means it has to run from a removable boot medium that can
 be accounted for at all times.

Overlooking the above points about physically-tampered machines (we
*really* shouldn't overlook them), I think this setup essentially means
that you can expect one of your lan peers to be compromised. But, as
long as your router isn't bugged, and as long as that peer isn't the

 This is completely dependent on who the adversary is, the level of
 sophistication, mistakes they may make, the resources they may have,
 how badly they want you, what they know about you, and what other
 precautions have been taken. A pin-hole camera for instance should
 not be enough to compromise a good setup.

How do you figure? (The camera can see everything you're typing and
your screen, right? If you have any additional biometric login
requirements, they can easily be gotten from you later.)


 Nor should a MBR level key logger installation. These two things are
 easier to do than a BIOS level modification. A BIOS level
 modification gets a lot more complicated as each system uses a
 different BIOS. When there is no generic solution to a problem or
 that solution is more cumbersome it may not exist. If it does exist
 it may be used much more selectively and there will almost certainly
 be fewer adversaries who have access to it. You may not be a target
 of a significantly high level adversary (where such levels may exist).
 
 
  Removable media may not eliminate the threat although there is less
  opertunity for a more sophisticated targeted attack. A software
  keylogger inserted into the MBR or similar would not be possible if

  But it will be available if you ever decide to boot, happily

 If the adversary does not have access to your boot medium how do you
 think they are going to install it? When you do boot it should not
 exist. There are few places that a keylogger or device can be
 installed. BIOS, optical drive, USB port, PC card slot, firewire,
 network etc. These are all things that can be checked. The only
 exception is the BIOS. The BIOS differs from machine to machine which
 should increase the cost of the adversary to produce a solution. I
 have never heard of a BIOS level bug. There have been conceptual
 modifications to suggest it may be possible although nothing in
 practice to show it could be done easily.
 
 Again, if you think your machine was actually tampered
  with, you should assume it's unusable.
 
 Nobody is arguing that a knowingly compromised machine or one that
 there is reason to suspect could have been compromised should be used.

But any machine that the adversary has physical access to should be
suspected to have been compromised. A BIOS-level bug, as you explain,
is one great way. Personally, I would prefer lower-tech spy solutions.
Of course, you can assume your adversary is weak, but that's a risky
assumption.


  On the other hand a physical keylogger may still be possible and

 I am looking into setting up a distribution where Tor or freenet is
 used to create a secure and anonymous environment for communicating.

Very cool. I've done that too :-).

 One of the issues with freenet is that it is slow. I haven't used it
 in many years and do understand it has gotten much better. I also am
 aware that after a few days it gets faster as popular data is
 retained and gets 'cached' on your node and nearby nodes based on
 what those around you are doing.
 
 What I'm trying to figure out is what happens when your node is not on
 24/7 and you can only connect infrequently for several hours at a
 time.

It runs at esssentially the same speed (minus the benefits of immediate
local caching, of course) -- which is pretty slow but manageable. It
may take a few seconds / a minute longer to fetch things, but that's
still a minute longer than the censored web provides, so either way
users will have to adjust their expectations. Booting into the network
will also take an additional minute or so, which always-on nodes don't
have to worry about.

 Many users have a persistent local threat that they need to be aware
 of. Leaving a server running is not an option as it could be
 compromised by an adversary.
 
 Removable media can reduce that threat.

The keyword being *reduce* :p. We all have that concern and fear, of
unforeseen zero-day linux exploits, etc. (We already know they exist in
Window$ :). Ideally you would want to make extra sure you have enough
contingency planning (proper permissioning / stable and patched
software / firewalls / perhaps caged virtual machines / sentry
programs / whatever your paranoia desires), so such fears are
minimized. They will never be eliminated though.

 What I'm looking to find out is if you run a freenode from a
 removable media and then run a local server running freenode to use
 as one of your peers (which could be on all the time) does this post
 a threat?

Besides the obvious risks of either of those machines being compromised
(by any number of ways: physically, buggy software, leaky software,
etc), traffic analysis will always be a threat with Tor, and also with
Freenet if bad guys have somehow managed to occupy all your peer
connections. But besides these well known threats, I think it's pretty
safe. But not perfectly safe.

 If no local server is run that you peer with how is the speed if you
 only connect every few days? Is running freenet for a few hours to
 several hours going to be sufficient or will it be unbearably slow?

It's bearable. (After it takes a few minutes to connect to the
network.) I suppose it's similar to fetching a freesite you never
fetched before -- perhaps a bit faster.

 With Tor speeds are frequently severely limited. Especially
 with .onion nodes. Some non-onion servers can be accessed with
 significant speed though for sustained periods (15-300... maybe
 faster).

That's probably not a Tor-specific problem -- but simply the less
powerful server behind the onioning. I don't think there are any
youtube-sized .onion servers.

Not necessarily -- any two or more nodes connected in any way --

 As Matthew already told you, finding out whether a socket has been
 disconnected can only be done by reading from or writing to the
 socket. We don’t do either until the request is finished. There’s
 your answer and it won’t change if you ask more often.

What determines whether a request is finished? When I browse freesites
normally, those requests expire gracefully.

Also, this bug (something fishy is definitely going on) is stranger
than I described, because I'm not exactly sure what creates those
abandoned open threads/sockets -- it's not simply a wget request, nor
one that ends in a failure (500 Internal Error) -- those all end
well. :S.

 I'm still not sure exactly how this bizarre behavior

All those HTTP socket handlers are still open and

Normal browser access to control localhost: does
still close the socket properly.

 No, they go on until they complete. There is a limit on the
 total number of connections handling requests, iirc the
 default is 100.

Well, I just checked -- all the 80 connections that were opened
a week ago are still open and still in CLOSE_WAIT. What does
until they complete mean? 
   
   The thread on Freenet's side will continue until it fetches the
   data. After that it *should* close the socket.
  
  So, to DOS freenet, I simply need to ask it to fetch old /
  not-fully-existent content?
  
   
Also, if I kept my wget spider running, it could easily
use 213 or over, like it did when I first reported the problem,
and eventually not let me back into fproxy :s. How does that fit
into the 100 request limit?
   
   Fproxy stops accepting more connections after 100 are running.
  
  How does that explain the 213 I originally saw? And why wasn't I

those connections into CLOSE-WAIT? (a la
http://www.tcpipguide.com/free/t_TCPConnectionTermination-2.htm
), or am I missing something?
   
   As I said before, we are not writing TCP packets directly. We are
   using a socket API. It is therefore somewhat painful to get
   notified when the socket is closed, if we are not actually
   reading from it - which we won't be while handling a request.
 
 I believe things have been fixed in 1404. (Many threads (~50) do
 linger for a while -- I'm not sure if this occurred before as well,

 False alarm. I think my freenet wget spider got out of control.
 Apologies.

Upon further consideration, I think it might actually be a bug. For one
thing, this never happened with earlier pre-1401ish versions. For
another thing, why are there so many sockets open, when my wget client
has long since closed and exited? (it has been about half an hour now --
I'll provide updates if they ever do close.) CLOSE_WAIT apparently
means fproxy got the FIN signal from my wget, but didn't close it's end?

I'm still not sure exactly how this bizarre behavior (of not closing
sockets) starts -- because if I restart freenet, and do a simple wget
transaction, the socket does get properly closed.

 how to update Freenet to the latest build. or change update.cmd to use

Is tor.eff.org also blocked? Perhaps you can use tor to access the
uncensored web. Or other open proxies?

Is http://code.google.com/p/freenet/downloads/list blocked?

If you trust toad/any of the freenet devs, you could find their GPG
key, (make sure it's their's) and ask them to send you the file
directly, then verify their signature of the sent file.

(You can also consider using linux distros, which use their own mirrors
for packages :).

I'm sure there are many other creative (and not so creative)
possibilities.

[freenet-support] Anecdotal: High IO when unable to connect to peers

2011-07-27 Thread Dennis Nezic
This is somewhat anecdotal and sparse on details, but probably something
significant. I have noticed that whenever I have trouble connecting to
peers, ie. when my version becomes too old to connect to the
mainstream nodes (I update my node manually -- gentoo package), the disk
IO skyrockets and my computer becomes bogged down (uptime values of 15
+), and I'm forced to kill the node. With the latest mandatory 1388,
(and my 1386), I'm actually not exactly sure if it's a peer-connectivity
(with some kind of disk-io hook? -- perhaps related to the node trying
to fetch the newer jars), or if it's normal while the node is starting
up. Either way, I can't start 1386 now, due to really high IO. I'll
test again when I get 1388 to install.

Yes. Freenet basically is a free (as in free beer) web hosting service,

stored redundantly across many *other* nodes -- not your own. (Freenet
also incidentally provides anonymity and is immune to censorship.)

 try to start freenet, I will get Firefox failed to connect to
 127.0.0.1:. Then after 8-10 seconds, freenet stops running.
 I am guessing this is a problem caused by the port used by Freenet
 before and after installing it, but I could be wrong, since I am not
 an expert. Please, could you guide me in how to change the ports
 Freenet connects to, or guide me to a solution for my porblems?

My stack dumps didn't show anything glaringly wrong. (No (or just once

shutting down FMS stopped the high-IO. (The reason why I originally
suspected Freenet was involved, however, was because stopping my node
also seemed to stop the IO a few seconds afterwards.) I'm still not
sure whether it's purely an FMS bug (perhaps having to do with my
150MB fms.db3 file), or some kind of FMS-Freenet interaction. I will
try to investigate further.

If the problem is with entropy, you can try running a large I/O

rngd (rng-tools).[1]

You can find how much entropy your system has available by:

Handwaving, since nodes are supposed to specialize over a specific key
range, and assuming keys are equally distributed across the entire
key-space, perhaps your 3% datastore utilization is a result of a small
freenet. Ie. a node can only store (specialized-key-range-percentage *
sizeof-freenet) gigs of data. If that's the case, the only way to
increase your datastore would be to broaden your key-storing-range, but
I don't think that would help, since freenet routing currently requires
key specialization.

Further handwaving, I wonder if it would be such a bad idea to support
supernodes, with broader key specializations. For example, would it be
a bad thing for a node to store the entire freenet?

 No need to defend, Matthew. The idea of internal censorship may be a 
 lousy one, at least it sounds like that to me.
 But the conclusion our anonymous crusader starts out with: 'proof of
 his hypocrisy' and you not to be trusted, is pretty ridicilous. Were
 you indeed not to be trusted, you wouldn't have done this
 brainstorming about a sort of censorship-from-the-inside in the open,
 and were you out on implementing whatever backdoor in FN in order to
 expose users, you'd surely not published about it at all.

That's exactly what I would do, if I was a malicious uber-coder, to win
your trust :D.

 So if I set

 and

   node.outputBandwidthLimit=25600
 and we've got us a new seed-node doing no more than 50KB/s?

Freenet doesn't strictly obey the incoming bandwidth limit, given the
nature of the UDP protocol. But, it will try to.

 On the contrary, some form of community-based censorship can be
 required for smaller communities to run Freenet in order to keep a

Well, clean and anonymity (free speech) are mutually exclusive. I

The sqlite3 (fms.db3) file. It contains all your options/identities, as
well as saved forum messages and trust lists. It probably would be
handy if it could be stored already encrypted on disk, but as you
suggest, it's not essential. I don't think you can change where it gets
saved -- not even via (sym)linking. (Because, I think, when it

Data distribution on Freenet doesn't work like that. Data segments are
actually spread all across Freenet, ideally with no particular peer
having a large portion of a large splitfile. I don't think having fast
random LAN connections would speed things up -- the bottleneck will
still be the LAN's connection to the Internet. (Not to mention the fact
that it would be at least somewhat less secure. (Better chance of

Freenet-Darknet should work wonderfully over such a network :). (Well,

 Ok, that was not your point :-) Ok currently maybe not too many nodes
 in the net but maybe this changes when governments restrict access to
 what you can browse. Here in Europe governments already start talking
 about installing filters.

This is why you /don't/ want any kind of broadcasting, or any other
kind of leak of identifiable traffic. Just encrypted non-identifiable
noise.

 Currently only for kiddy porn but I'm afraid that when such a filter
 is in place the step to block certain political views or so is much
 smaller.

Obviously. Their (Statist's) worst enemy is the free flow of
information.

 It is also a matter of convenience. If I visit some conference I don't
 want to be hassled with the need of configuring all kinds of software
 just to get work done.

It's a tradeoff -- ease-of-use and anonymity.

 No idea how to implement that de-centralized. Also you don't want to
 depend on 1 server keeping it up-to-date.

One way might be to have a spider, or person, collect vcard or any
other kind of information from freesites / freetalk/fms forums / etc,
and then make a freesite-directory :).

 How does the freenet forum work?

There are 2.5 current independent forum systems in the wild. FMS,
Freetalk and Frost. They work well. (FMS the best. /me ducks/ :).


   4. maybe it is an idea to add a list of listening ports to the
   'list of plugins'-page
  You mean the ports that plugins (like Freemail) might use?
 
 Correct!

Good idea. In the meantime, you can run netstat -pna | grep java,
assuming Freenet is the only java app running.
