{Also considered apcupsd (http://www.apcupsd.org/) - only APC, prefers 
 to sit on top of NIS for multiple machines.}


RH7.3
-----
Ensure NUT (0.45) from distro is installed.

[Create user:
  groupadd -g 499 -r upsmonitor
  useradd -c "UPS monitoring user" -g upsmonitor -r -u 499 upsmonitor
]

Fill out /etc/ups/* and /etc/sysconfig/ups.

In /etc/rc.local 
	amend serial port permissions to allow user access
	then restart ups (NUT) daemons.

Modify swatch.conf.

Download nut-1.4.3.tar.gz, check and unpack.

[Create user:
  groupadd -g 499 -r upsmonitor
  useradd -c "UPS monitoring user" -g upsmonitor -r -u 499 upsmonitor
]

Compile:

  export CFLAGS="-march=athlon-xp"
  export CXXFLAGS="-march=athlon-xp"
  export F77FLAGS="-march=athlon-xp"

  ./configure --with-user=nut --with-port=3305  --sysconfdir=/etc/ups \
  --with-cgi --with-drivers=apcsmart,newapc,genericups
(newhidups fails to find some headers)

  make

As root:
  make install
  mkdir /var/state/ups
  chmod 0700 /var/state/ups/
  chown upsmonitor:upsmonitor /var/state/ups/

Don't do serial port permissions for now, as monitoring another machine.

Create /etc/ups/upsmon.conf

	RUN_AS_USER upsmonitor
	MONITOR smrtpwr750@ide-raid01:3305 1 upsmon passwd slave

and 
	/usr/local/ups/sbin/upsmon

Test by yanking out lead.

Add swatch rule

Download nut-2.0.3.tar.gz, check and unpack.

Create user:
 groupadd -g 499 -r upsmonitor
 useradd -c "UPS monitoring user" -g upsmonitor -r -u 499 upsmonitor

Read doc/configure.txt:
--with-port=PORT

   Change the TCP port used by the network code.  Default is 3493.

   Ancient versions of upsd used port 3305.  NUT 2.0 and up use a
   substantially different network protocol and are not able to
   communicate with anything older than the 1.4 series.

   If you have to monitor a mixed environment, use the last 1.4 version,
   as it contains compatibility code for both the old "REQ" and the new
   "GET" versions of the protocol.

Doh!
