README for PRNGD HP-UX rc scripts

prngd:		configuration file for prngd.rc
prngd.rc:	PRNGD startup script

Please read 00README from the PRNGD distribution for instructions on
installing PRNGD; this README covers a recommended runtime and startup
configuration for HP-UX.

o Verify prngd path in prngd.rc matches your local installation.
  WHAT_PATH is set to /opt/local/bin/prngd; you will need to change
  this if your prngd executable is installed in a different location.  

o Customize prngd configuration file if needed (PRNGD_ARGS and
  PRNGD_LOG)

o Add pseudo account:

  # groupadd prngd
  # useradd -g prngd prngd

o Setup directories:

  # mkdir /etc/opt/prngd
  # chmod 755 /etc/opt/prngd
  # mkdir /var/opt/prngd
  # chown prngd:prngd /var/opt/prngd
  # chmod 755 /var/opt/prngd

NOTE: here we assume the following changes in config.h:
#define RANDSAVENAME	"/var/opt/prngd/prngd-seed"
#define CONFIGFILE	"/etc/opt/prngd/prngd.conf"
Alternatively, PRNGD_ARGS can be used at runtime as proposed in the prngd
configuration script.

  # cp prngd.conf.hpux-10 /etc/opt/prngd/prngd.conf
  # chmod 644 /etc/opt/prngd/prngd.conf
  # touch /var/opt/prngd/prngd-seed
  # chown prngd:prngd /var/opt/prngd/prngd-seed
  # chmod 600 /var/opt/prngd/prngd-seed
  # (netstat -s;netstat -an) >/var/opt/prngd/prngd-seed
  # ln -s /var/opt/prngd/egd-pool /var/run/egd-pool

o Install rc scripts:

  # cp prngd /etc/rc.config.d
  # chmod 444 /etc/rc.config.d/prngd
  # cp prngd.rc /sbin/init.d
  # chmod 555 /sbin/init.d/prngd.rc
  # ln -s /sbin/init.d/prngd.rc /sbin/rc1.d/K600prngd
  # ln -s /sbin/init.d/prngd.rc /sbin/rc2.d/S400prngd

o Start PRNGD:

  # /sbin/init.d/prngd.rc start
