## <a name="Setup_pseudo_random_devices"> Setup pseudo random devices </a>
Stuck getting SSH to work? You need a pseudo random generator (PRG).
There are several solutions to the lack of /dev/random and /dev/urandom, but they are not yet in the default installation.
* Marcus' work can be downloaded at: [random.tar.gz](ftp://alpha.gnu.org/gnu/hurd/contrib/marcus/random.tar.gz) (identical to <http://kilobug.free.fr/hurd/random-64.tar.gz> ?)
* [A patch](http://mail.gnu.org/pipermail/bug-hurd/2002-August/010248.html) that was probably already incorporated from August 14, 2002.
* Clemmitt Sigler [reported success](http://lists.gnu.org/archive/html/help-hurd/2002-10/msg00076.html) October 11, 2002 and Marcus [described some](http://lists.gnu.org/archive/html/help-hurd/2002-10/msg00081.html) of the internals.
* [egd](http://egd.sourceforge.net/) - Entropy Gathering Daemon (here's the [RFP](http://bugs.debian.org/145498))
* [OSKit Entropy Patch](http://lists.gnu.org/archive/html/bug-hurd/2003-01/msg00000.html) from Derek Davies - Jan 2003. See also [this page](http://www.ddavies.net/oskit-entropy/index.html).
* Note that this patch can (and should) be used with this[ OSKit NIC patch](ftp://flux.cs.utah.edu/flux/oskit/mail/html/oskit-users/msg01570.html).

## <a name="Setup_tips"> Setup tips </a>
Here are some tips on how to actually setup the two random devices using Kilobugs' [random-64 server](http://kilobug.free.fr/hurd/random-64.tar.gz). His tarball is a complete Hurd server including a pre-built binary - so you don't need GCC or magic fingers for this! :)
After untaring the package you copy the random binary to the /hurd directory. Then you setup the translators for random and urandom.
# settrans -c /dev/random /hurd/random \
--seed-file /var/run/random-seed --secure
# settrans -c /dev/urandom /hurd/random \
--seed-file /var/run/urandom-seed --fast
# chmod 0644 /dev/random /dev/urandom
