Re: [GNUnet-developers] GNUnet 0.5.5 released

I had some very similar fun trying to make it work under solaris/BSD shortly 
before the release (and my fix had a small problem, resulting in the 
segfault-bug reported for 0.5.5). Anyway, the problem was that the PRNG of 
gcry tried to read random numbers from "/dev/random", which did exist but 
never produced any bits (cat /dev/random blocked on the shell, too).  

I tried to fix this by using "/dev/urandom" on BSD (and putting a warning 
since the PRNG is possibly not good enough in that case). I don't know 
exactly what is wrong with the code (I didn't write it in the first place, 
was "stolen" from libgcrypt). I have the feeling that the entire PRNG code of 
gcry needs to be looked at & cleaned up. 

Anyway, I suspect that you have the same problem in that it tries to get 
random bits from /dev/random and fails. 

Note that this code is ONLY used if you do NOT use OpenSSL *and* if you are 
generating a fresh hostkey, which is probably how it managed to slip by in 
the first place.
