Re: [GNUnet-developers] newbie Q: connecting ..

Hi Christian

Here's more info, apologies if it's too much ..

[Hey, it works! See end .. ]

Weird, that URL lists 0.4.6, which is what I had when I wrote the
original post, but they're distributing GNUnet v0.5.2a now, so
the URL is out of date. And I would have expected it to be
autogenerated when they updated the distributed version. I'll check
it out and file a bug report if necessary.

I'm on a 650Mhz PIII IBM Thinkpad 600x with 256MB RAM.

address@hidden src $ ldd `which gnunetd`
        libgnunetutil.so.0 => /usr/lib/libgnunetutil.so.0 (0x41017000)
        libdl.so.2 => /lib/libdl.so.2 (0x41029000)
        libm.so.6 => /lib/libm.so.6 (0x4102c000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x4104e000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x41063000)
        libcrypto.so.0.9.6 => /usr/lib/libcrypto.so.0.9.6 (0x410b4000)
        libc.so.6 => /lib/libc.so.6 (0x41178000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40ff7000)

Current symptoms is that this does nothing:

address@hidden jean $ gnunetd

and ps shows no gnunetd. If I tell it not to detach:

address@hidden jean $ gnunetd -d
Jun 16 01:05:53 Could not open library libgnunetafs_protocol.so 
(libgnunetafs_protocol.so: cannot open shared object file: No such file or 
directory)!
Jun 16 01:05:53 __BREAK__

I was a bit surprised that this:

klippie jean # grep -r libgnunetafs_protocol.so /var/log/

didn't show any trace of the first invocation failing.

> All GNUnet dependencies are listed at 

Thanks. In a previous post I'd also found the dependencies to be due to
doc generation.

I've done
 ./configure --prefix=/usr/bin
 ./make
now. This built libgnunetafs_protocol.so, which I copied into place:

cp 
/home/jean/src/GNUnet-0.5.2a/src/applications/afs/protocol/.libs/libgnunetafs_protocol.so 
/usr/lib/

and now gnunetd starts up OK. (To avoid copying files around that aren't
under Gentoo package management I'll still have to figure out why the so
didn't get built in the first place ..)

It still doesn't talk though:

address@hidden GNUnet-0.5.2a $ gnunetd -d

The config file is unchanged from the distro except for s/eth0/ppp0/

Hmm, now it's suddenly more chatty:

This breaks:

Did not receive the message from gnunetd. Is gnunetd running?

It results in:

I might mention that I'm on a dialup connection that sucks very hard, but
very ineffectively:

Perhaps this is too noisy for gnunet. Let's try a search ..

Thanks for the help :]  I was thrown by gnunetd's debug messages: I thought
they were all signs of misconfiguration. I didn't realise that they were
diagnostics and that gnunetd just needed a while to orient itself, as it
were.
