Hi Debra,

First of all, if you want to use PRNGD, EGD is OPTIONAL end NOT mandatory on SOlaris 2.6

for compiling EGD you have to do:

Take your source files and decompress them

gzcat egd-0.8.tar.gz | tar xf -

Now, go into EGD dir and:

perl Makefile.PL
make
make test
make install

# mkdir -p /opt/prngd/bin
# mkdir -p /opt/prngd/etc

# gzcat prngd-0.9.25.tar.gz | tar xf -
# cd prngd-0.9.25

# cp -p contrib/Solaris-2.6/prngd.conf.solaris-26 /etc/prngd.conf

vi Makefile

Find and Set this variable:

DEFS=-DRANDSAVENAME=\"/opt/prngd/etc/prngd-seed\" -DCONFIGFILE=\"/etc/prngd.conf\"

Compile PRNGD with these options:

# make CC=gcc CFLAGS="-O3 DSOLARIS" SYSLIBS="-lsocket -lnsl"

If those options don't run, use these:

# make CC=gcc SYSLIBS="-lsocket -lnsl"

Now proceed to PRNGD configuration as follows:

# cp -p prngd /opt/prngd/bin

# cat /var/log/syslog > /opt/prngd/etc/prngd-seed

# mkdir /var/spool/prngd

Now execute PRNGD daemon as follows:

# /opt/prngd/bin/prngd /var/spool/prngd/pool

you can create PRNGD startup script:

# cd /etc/init.d
# vi prngd

#!/bin/sh

pid=`/usr/bin/ps -e | /usr/bin/grep prngd | /usr/bin/sed -e 's/^ *//' -e 's/ .*//'`
case $1 in
'start')
        /opt/prngd/bin/prngd /var/spool/prngd/pool
        ;;
'stop')
        if [ "${pid}" != "" ]
        then
                /usr/bin/kill ${pid}
        fi
        ;;
*)
        echo "usage: /etc/init.d/prngd {start|stop}"
        ;;
esac

Now, create links:

# ln -s /etc/init.d/prngd /etc/rc0.d/K30prngd
# ln -s /etc/init.d/prngd /etc/rc1.d/K30prngd
# ln -s /etc/init.d/prngd /etc/rc2.d/S20prngd
# ln -s /etc/init.d/prngd /etc/rcS.d/K30prngd

You can verify prngd functionality with EGD PRNGD:

# /usr/local/bin/egc.pl /var/spool/prngd/pool get
 10211 bits of entropy in pool
