I'm fairly certain /dev/urandom is broken. I'm trying to setup a machine to investigate this failure of Crypto++ (https://buildd.debian.org/status/fetch.php?pkg=libcrypto%2B%2B&arch=hurd-i386&ver=5.6.4-9&stamp=1565561714&raw=0):
Testing operating system provided nonblocking random number generator... FAILED: 100000 generated bytes compressed to 98749 bytes by DEFLATE The problem could be Crypto++, but... I performed a apt-get install: gcc g++ gdb git subversion automake autoconf libtool Some Python package complained it failed to get random numbers. I just performed an apt-get install: emacs-nox And GnuTLS failed to initialize due to the random number generator. Three different programs are failing due to the random number generator. Something is sideways with /dev/urandom on this distribution.
