They should all be working since the inform.php script regularly tests
them by opening and closing a TCP connection.

Such nodes shouldn't get into the inform.php list.

Shame - I actually get pretty darn good reliability, I recently
downloaded a "Homer Simpson" mp3 which has been on the key list for
ages, and probably wasn't really requested very much.
I think that the problem is that most content isn't being requested
enough - and that is because there is no content on the system that is
really drawing people to use it on a regular basis. This is a catch-22
situation which will hopefully be addressed when, say, Freenet is
included in Debian-unstable and forms a viable mechanism for downloading
new Debian releases. This really needs to wait for a GCJ-compiled
binary version of Freenet which seems to be getting closer by the day.

Yes. As I said, hash the recombined data and compare with the hash of the
original. They WILL differ, most likely because of your defective
floppies.

I've asked a couple of times to find out others experience in retrievability
from a second node immediately after inserting files. My experience has not
been good as detailed in my post of 1/16/01 and reposted yesterday. I've not
run any tests since 1/16/01; maybe it's different now.

It seems to be possible for a node to enter a state where it accepts TCP
connections but doesn't do the handshake... The client outputs something like
this:
Freenet Core running on 2702 (build 161)
Authentication timed out
Freenet.ConnectFailedException
at Freenet.Core.makeConnection(Core.java:294)
at Freenet.client.Client$BInstance.prepare(Client.java:212)
at Freenet.client.Client$BInsertInstance.prepare(Client.java:442)
at Freenet.client.Client$BInstance.run(Client.java:230)
at java.lang.Thread.run(Thread.java:484)
A fatal exception occured while processing: Freenet.ConnectFailedException
State "FAILED" reached.
My node does this every so often, I believe it's related to the 100% cpu
problem...

I'm hopefully almost there. My GMP code is all together, but I'm waiting
for one of the RedHat guys to fix a bug in the higher-level
BigInteger.divide method that's messing up everything that depends on it,
which is a lot of stuff.
Anyway, I have a question about libraries and linking. I want to
incorporate all the needed libgcj code into the libfred.so library. How do
I do this? I'm aware of the -shared and -static options, but how do I make
a shared library with statically-linked code (that doesn't depend on the
gcj library). Is it ALREADY that way? I'm lost here...

I also see these, basically whenever I stress my node with multiple
concurrent inserts or requests.
I am convinced that something is being leaked inside Fred on a per request
basis (maybe just for some uncommon failure mode?). I haven't been able to
track it down though.
Even if I allow 200 inbound threads, I eventually start to see Authenication
timed out and/or Can't connect to null address errors, when running multiple
concurrent requests.

Subject: [freenet-devl] [Freenet-dev] Intermittent booster leaf
Reply-To: devl at freenetproject.org
Hello,
A way of using intermittently connected machines is to use them as leaves which
only store and provide data instead of nodes with store, provide data and route
requests. Meaning right now all freenet nodes are equal and should have a
permanent internet connection; a 'leaf' could be useful even if it is only
intermitetly connected, like through a dial up account; however when it turns
on, it would look for a few permanent nodes and tell them that it can supply the
data behind a list of keys, that it can store an extra amount of data; but, that
is all. When it turns off, it tells the nodes it has contacted that it is no
longer available. When one of the contacted nodes gets a request for a key, it
searches its own hard drive, if it's not there it then looks to see if any
intermittent node can handle the request and if it's not there it then sends the
request along.
This would be useful in three ways, one is that this makes the extra storage and
bandwidth capacity of intermittently connected machines available, people who
want to keep certain information always available can store it on their own hard
drives, never deleting it and in pro censorship areas, the permanent nodes could
rely entirely on the intermittent leaves for data, storing none on their own, so
they wouldn't have any objectionable data on them. Censors would be forced to go
after more individuals, rather than a few high bandwidth servers.
This can be seen as dividing the functions of a freenet node into searching /
routing and storing / transfering, which right now every node has both, into two
sections. The typical freenet node could now either search, search and store or
store. From a programming perspective, since the current nodes already do all of
this, writing leaf nodes could be kept in the same cvs tree, as long as their
interfaces are clearly divided between searching and storing. A search only node
would be useful in pro censorship places so that freenet can continue even if a
few machines are outlawed. A search and store node would be the current freenet
node, useful in free information places. A store node would be useful for
people, who have intermittent connections, usually operated from their homes.
Cheers,
Enrique

Agreed, the initial harsh approach was in an environment when there were
a huge number of screwy nodes, where as the improved inform.php has
helped to address this issue.

Reply-To: devl at freenetproject.org
Hey, so, I put freenet-0.3.7 up. I'm hoping I got it all right -- it
seems that way, at least.
I left out a lot of cruft, and optimized stuff, but the packages are
like 100Kb smaller than 0.3.6. Hopefully I didn't leave out -too-
much. Comparisons of the two filesets seems to suggest that the new
one is correct, though. So go figure.
I used the ant buildfile for this, but I also used the mkDist.sh and
they came out with almost identical output.
Hammer away, folks.

Computers are not voodoo. A file is just series of numbers. Please explain

Hmmm... directory, permissions, owner, group, ACLs... I can think of
tons of reasons. I don't think any of those things would make rpm
segfault, but it's possible.
