I've been using a script for over a month, sending Toad an hourly node status. He mentioned it would be great if some other people would run it. Since I couldn't bear to send in the mess I have been using, I fixed it up a little. Then I tested it. It didn't work anymore, so I fixed it up some more. Now it works.
Use mailFredStatus --help to find out how to use it. Most things you would want to change you can specify once on the command line followed by --writedefaults and your choices are written to ~/.mailFredStatus Put the script into your freenet directory alongside freenet.jar and freenet.conf. 9a976e9ff02309007f8bcc4be4b35a7c /home/ejhuff/freenet/mailFredStatus 1e1a9ad7830bbcb2592073c64da0a90e /home/ejhuff/freenet/mailFredStatus.asc 5d71baf9ed089e0a115d066222187ec0 /home/ejhuff/freenet/gpg-key-D5FA1719 -- Ed Huff

NAME
mailFredStatus - Mail Freenet REference Daemon status to Toad
SYNOPSIS
mailFredStatus [ --help | -h | --version | -v ]
mailFredStatus [ --to '$TO' ]
[ --from '$FROM' ]
[ --BCC '$BCC' ]
[ --interval '$INTERVAL' ]
[ --servlet '$SERVLET' ]
[ --FreenetHOME '$FREENETHOME' ]
[ --dryrun | --golive ]
[ --sendmail '$SENDMAIL' ]
[ --tc '$TC' ]
[ --verbose ]
[ --writedefaults ]
DESCRIPTION
mailFredStatus will collect status information from
the Fred FProxy server at localhost:8888, from freenet.conf,
and from netstat, and mail it to Toad once an hour.
The command never exits unless interrupted or killed.
Uses sleep to delay, so intervals are approximate.
The --golive option must be specified to actually
send any mail. To make --golive the default, use
this command, with desired defaults specified.
mailFredStatus [defaults] --golive --writedefaults
This will not actually go live, but the next time
mailFredStatus is invoked, it will start running.
--verbose will cause the -v option to be passed
to $SENDMAIL.
FILES
~/.mailFredStatus
If ~/.mailFredStatus exists then this script
sources it. It should assign default values to
the environment variables. The --writedefaults
will overwrite any existing ~/.mailFredStatus
specifying the options from the command line as
the new defaults. Remove the file to use the
original defaults.
ENVIRONMENT
PATH must include wget head egrep grep sort sed date
If exported to the environment, these environment variables
will be used as the defaults for the corresponding options.
Or, if defined in ~/.mailFredStatus, then those values
will override environment or script defaults.
They do not override command line options.
Shown are the values which were in effect after
processing the command line which caused this printout.

INTERVAL="$INTERVAL"
SERVLET="$SERVLET"

VERBOSE="$VERBOSE"
SENDMAIL="$SENDMAIL"

FEATURES
Only works on Linux. Uses bash-isms.
Uses wget to read data from servlet on port 8888.
BUGS
Extracts data from web pages, so that innocent changes
to fproxy formatting may break this script.
Isn't written in [ perl | java | /bin/sh | ... ]
Uses sendmail to send mail.
