 I'm running a recent Freenet snapshot (from freenetproject.org/snapshots/
 at the time when it said freenet-latest.jar  23-Aug-2002 00:01   1.1M).
 Platform is OpenBSD 3.1, using the Linux JDK 1.3 (reported as Sun
 Microsystems Inc. version 1.3.1_04 in :8890/).
 
 When I connect to the FCP port, it accepts the connection, then
 immediately closes it:

Following up to this:

I poked around a bit using ktrace/kdump and found that the Freenet
java process was getting a Resource temporarily unavailable error
while attempting to read 1 byte from a file descriptor which I believe
was the socket.  This problem occurred on all Freenet ports, not just
the FCP port.

It seems that there's some sort of weird timing/blocking issue going
on with this Java VM under OpenBSD (possibly a problem with the Linux
emulation?).  If I execute this command:

  $ telnet pegasus 

then it closes the connection as I indicated earlier.  But if I execute
this command:

  $ echo -e 'GET / HTTP/1.0\n' | nc pegasus 

then it works correctly.  This makes me suspect that a read() from the
socket which was supposed to be blocking was actually being done in
non-blocking mode.  Or maybe it's some other bug somewhere.

I've switched to kaffe (which I had to use a bit of hackery to build;
I've sent a message to the kaffe mailing list, but it's pending moderator
approval), and the behavior seems to be much improved.

So in summary, for OpenBSD users, kaffe 1.0.7 seems to be mandatory.

 What did you need to do to get Freenet working with Kaffe?  Someone 
 should write a HOWTO in the public section of the website.

Once Kaffe 1.0.7 was installed, I did nothing special to make Freenet
use it.  (Special may be relative to user skill, of course.  Note
that I'm Cc'ing support@ on these because I do think that a wider
audience is justified.)

 Pending moderation probably means that you need to be subscribed to 
 the mailing list to send a message to it.  I don't know about the Kaffe 
 mailing list maintainers, but if I didn't ignore it when that happened, 
 I would spend all of my time approving/disapproving emails to the 
 mailing lists.

According to their web-based mail archive, it went through.

Anyway, here's exactly what I did:

0) This is an i386 OpenBSD 3.1 box.
1) Downloaded kaffe-1.0.7.tar.gz from www.kaffe.org, and extracted it:
gzip -dc kaffe-1.0.7.tar.gz | tar xvf -
cd kaffe-1.0.7
2) ./configure; make
3) The make failed because of an ld error, shown earlier in this thread.
4) Went to the directory where the failure occurred, and ran this command:
 cd kaffe/kaffevm/.libs
 ln -s libkaffevm-1.0.7.so libkaffevm.so.1.0
 cd -
5) Typed make again in the top-level directory.  It worked.
6) make install
7) Adjusted /usr/local/bin/java and javac symlinks to point to Kaffe:
 cd /usr/local/bin
 mv java java.old
 mv javac javac.old
 ln -s ../kaffe/bin/java java
 ln -s ../kaffe/bin/javac javac
8) Went to /usr/local/kaffe/jre/lib/i386 and added the symlink:
 cd /usr/local/kaffe/jre/lib/i386
 ln -s libkaffevm-1.0.7.so libkaffevm.so.1.0

That's it.  My freenet node's run script just calls java, so it
finds the symlinks in /usr/local/bin.

Feel free to use this information however you wish.
