Subject: [freenet-devl] 0.3.7 windoze bugs
Reply-To: devl at freenetproject.org
1. After installing
http://download.sourceforge.net/freenet/Freenet_setup0.3.7.exe
on a fresh win2k box, my .fproxyrc file contained:
[FProxy]
# serverAddress points to the host:port on which you are running the Freenet
node
serverAddress=tcp/127.0.0.1:19114tcp/127.0.0.1:60499
...
So fproxy just hung.
2. When I run the GUI configurator, and changed the port from the installation
assigned (60499) to my firewall friendly 11849, it
only changes freenet.ini. I had to manually change .fproxyrc and FLaunch.ini.
Now all is well.
It seems a previous installer (0.3.3?) asked for the port address before
generating the config files. Can we add this to the new
installer?
3. Add/Remove Programs says Freenet 0.3.5 is installed.

I just did a jni impl of twofish and rijndael and it made no difference
whatsoever even though the C version is at least twice as fast as the java
version. The java runtime compiler must have fits with jni. Anyway, I
could be underestimating the raw Rijndael cipher performance cost by quite
a bit...
