Here is another update to the planner script that has been contributed
to by countless users that are all mentioned throughout the README file. I
have certainly contributed the least to any of the code of this project,
but was more concerned with putting some utility and functionality into it.
   Hopefully people will continue to have more ideas that they can put into
this. In case people are curious, I've logged approximately 30,000 finger
requests to my account, and it's still as reliableas ever. I have looked
at all the available packages, and have to say that this seems to be the
sturdiest and "frilliest" package that is available. Basically lets you do
anything to your .plan that you could ever want. Check it out by fingering
    [e-mail]

The change to this package that merits a repost is that it will no longer
hang your machine when a mirror host (NFS mounted volume) is fingered. Before,
the .plan was a named pipe which pointed to a background process. However,
this background process did not exist on other machiens that had the same
file system, so it would just hang the finger daemon (bad). So, to get around
this, the named pipe is placed in the /tmp disk, and a symbolic link to
the .plan file is made (credits go to Fumiaki Kamiya). Then, people will
simply get a "No Plan" message when they finger other hosts that do not have
the resident background process.

People should also note that this is incredibly cpu-friendly. It gets the
host-name of the machine that is fingering you through a simple step involving
netstat (but only taking a head-20 of the output).

It should also be noted that this will NOT run on ULTRIX, disabled finger
daemons, or, of course, VMS. I would not recommend that any new users
work with this, because it can definitely peeve your system administrator,
and because you will have to play with the code to get it working. To any
moderate to advanced UNIX user, it should be quite easy - just take a bit
of tweaking. I haven't been able to figure out an easy way to make the code
universal, because there are so many places where you have to change pathnames,
usernames, etc. But, you should be able to get it running flawlessly in under
an hour at the very most.

Hoping you have fun with this, and hoping your New Year's Celebration was
as good as mine,

Steve Franklin

XCompiled on January 1st, 1994
X
XBefore I continue by describing what all of this does, I should point out that
XI am not the original author of this software. I have modified it like
Xmany before me and am now trying to simplify the documentation as so many
Xusers have requested.
X
XPurpose: The purpose of planner is to create an ultra cool .plan file so
X         that people can get random .plan's when they finger you. It
X         can be used in a variety of ways, and depending on how creative
X         you are, can make you rich beyond your wildest dreams (well, sorta)
X
XContents:   Makefile      Self-explanatory - type "make" to compile
X            delplan       Kills the current running plan process on this host
X            killplan      Creates an at job to keep track of plan so that if
X                          the machine reboots, then it resets itself
X            logfinger     Hardly changed this - perl script to log whos fingering
X            lf            Short script to let you know when you were last fin'd
X            plan.1        Man page
X            plan.c        C-code for the plan application
X            planner       Shell script that shows a couple of neat tricks
X            readme.orig   Original read me that was getting a tad "congested"
X            renewplan     Script for starting up plan cleanly.
X            rf            Takes a numeric argument to show you the last # of
X                          fingers
XChanges: The latest big change has been the eradication of the 'hanging'
X         problem on shadow machines (NFS mounted volumes). To get around
X         this, Fumiaki Kamiya <[e-mail]> recommended putting
X         the named pipe file on the tmp disk, then doing a symbolic link
X         to the $HOME/.plan file. Then, when fingered on any mirror sites,
X         the .plan file doesn't point to anything, giving the "No Plan" msg.
X
X         The original plan seemed quite concerned with who was fingering you
X         from your local machine, but just logged "somebody" as fingering
X         you if it was from another machine. All it took was a few additions
X         (a la netstat) to let you figure out which machine is fingering you
X         and a few more changes to impress the fingerer by letting them
X         know their hostname. These settings are recorded into a file that
X         you can later query.
X
XRequirements:  In order to run plan, you need bsd-ish architecture. Users
X               running ULTRIX are out of luck, as are VMS users of course.
X
XInstructions:  The simplest way to sort through this is to first edit
X               "planner","renewplan" and "logfinger" to resemble your environ.
X               and your preferences. Then, place plan and renewplan in
X               your bin directory or any dir that your $PATH variable points
X               to. Simply type "renewplan" and it does the rest for you.
X
XQuestions:     Feel free to send questions to [e-mail]
X               but please try to read through all the documentation as well.
X
XCautions:      If your machine reboots, you will have an empty named pipe
X               pointing at no process (it doesn't exist since the machine
X               rebooted). So, you have to restart the plan process (renewplan)
X               after a reboot. If you don't catch it, people's finger
X               processes will clog up your finger port. To get around this
X               I had an "at + 1 hour..." included in "renewplan" to re-exec
X               renewplan every hour - if there was a reboot, plan would
X               start up no more than an hour after the reboot.
X
XExample:       Check out [e-mail] for an example of how the
X               planner pipe can be used - hopefully it's up and running :)
X               Hopefully you guys will mail me if you get neat ideas of
X               your own...

XAll I did was to put in a function that keeps track of the PID for
Xplan by writing it to a file called ".planpid" in your home directory.
XNow you run plan in your .login, and, to kill the process when you log
Xout, put something like this in your .logout:
X
X    kill `cat /home/mine/.planpid`
X    rm -f /home/mine/.planpid
X
XYou have to remove the .planpid (or modify the code), because the
Xprogram will not run if a plan is already running, which it assumes
Xwhen it finds a .planpid file already there.
X
XIf someone wanted to run multiple plans, maybe one for a .signature
Xand another for a .plan, the save name for the PID could be changed,
Xand the program compiled twice (the binary is not that big, ~40K on
Xthe HP 425's I used), or, if someone is really motivated, they could
Xadd a command line argument for the save name.
X
XSure, my modification isn't very complex, but it does what I needed
Xit to do, and maybe someone else can use it.

X****  Additions by Geoff Loker ****
X
XI have modified Tony Rems' code for plan a bit to get rid of the
Xnecessity for hard-coding in the file name to be set up as a FIFO.
XThe program will now accept an optional argument that specifies the
Xname of the FIFO to be used.  If that argument is not set, the default
XFIFO is $HOME/.plan.
X
XIn order to use this program, your O/S needs to support named pipes.
XYou also need to link in getopt for the changes to work.
X
XAny executable program can be set up to run when the specified FIFO is
Xopened, but don't forget that the program you specify to run is being
Xrun under your userid.

XHere is the article which appeared in comp.unix.questions a while back.  It
Xcontains generic code that will run any program you want whenever a certain
Xfile is accessed (i.e. the .plan file in this case).  All you have to do is
Xcompile it (it creates an executable called 'plan') and then to get it
Xrunning say 'plan a.out &' where a.out is some program you have written.
XI don't have my program any more, but basically what I did was a ps au
Xwithin that program.  It used egrep to search for someone currently fingering
Xme and appended the output to a file.  To get really fancy you could then
Xread from that file to find out exactly who it is (all in the same program)
Xand print out a nice personal message to whoever is fingering you as part
Xof what looks to be your .plan file.  A couple of things to watch out for:
XIf the finger is remote, the ps au won't find anything.  Also, if two people
Xfinger you at the same time you may run into trouble, but I didn't try
Xexperimenting with this too much.  I also found it helpful to timestamp a
Xdate to the file, too (I used localtime() for efficiency).  This makes it
Xeasier to look back later at the file and see who's been fingering you and
Xwhen while you were not logged on.  It also helpful in debugging your program.
X
XSo set up this code and experiment with different programs.  Just be creative
Xand see what else you can do with it.  One idea I used for a while is making
Xit print a different quote each time.  The possibilites are endless.  Enjoy.

XAs you have found out by now, I'm sure, the p means that this is
Xa named pipe aka a FIFO.  If you'd like to do this yourself, here
Xis a little program I wrote to do it (see the comments at the
Xthe beginning of the plan.c file for usage info):
X
XHere's the shar of my plan program, just cut up until it says
X"cut here", and then type 'sh filename' using whatever filename
Xyou save it as.  If you use 'plan' it will get overwritten.
X
XThe code here should compile w/o any problems on any BSD machine,
XI have tried it on a Sun, Vax 750, and Pyramid 90x.  It should
Xalso work properly on any SVR4.0 machine.
X
XThe code is pretty heavily commented so it should be self
Xexplanatory.
X
XNote that you should put a -DFILENAME="your_home_dir/.plan"
Xto get it to put your path in, or you can just edit the
Xsource and change the value of FILENAME permanently.
X
XIf you have any problems getting it compiled, just send me mail.
X
XEnjoy.

X.SH NAME
Xplan - run an executable when a specified FIFO is opened
X.SH SYNOPSIS
X.B plan
X[
X.BR -d
X] [
X.BR -f file
X]
X.B executable
X.SH DESCRIPTION
X.I plan
Xtakes the name of an executable program and runs it on a FIFO that
Xis specified on the command line or on a FIFO in the user's home directory
Xnamed .plan.  Whenever the FIFO is accessed, the output of the executable
Xprogram goes to the FIFO.  It writes it's PID a file, so the process
Xcan be killed during logout, and it checks for the existence of this
Xfile to make sure plan isn't already running.
X.SH OPTIONS
X.TP
X.B \-d
XRun \fIplan\fR in daemon mode.
X.PP
X.TP
X.B \-f file_name
XThe \fB\-f flag causes \fIplan\fR to set up the specified \fBfile_name\fR
Xas a FIFO rather than the default \fB$HOME/.plan\fR.
X.PP
XSome sample uses of \fIplan\fR would be:
X.TP
X.B plan -d /usr/games/fortune
XThis will display a randomly selected fortune as the contents of
Xyour .plan file whenever you are fingered.
X.TP
X.B plan -d -f ~/.signature ~/bin/gensig
XThis will run the program gensig whenever your .signature file is accessed,
Xallowing you to change your .signature whenever you post.
X.TP
X.B plan -d ~/bin/logfinger
XThis will run the program logfinger whenever your .plan file is accessed,
Xand you can log all instances of people fingering you.

XTony Rems ([e-mail])
X.PP
XModifications by Geoff Loker ([e-mail]).
XMore modifications by Karen Bruner ([e-mail]).
XEven more modifications by Norman Franke ([e-mail]).
X.SH BUGS

X    hardcoded in.  Now any number of users can use the program at the same
X    time.  I also modified the program to use an optional argument to
X    specify which file to use.  The default file used is still the user's
X    .plan, but this can now also be used to set up .signatures or any other
X    file the user wants.

X
X    Added pid_deal function, so people can stick the program in their
X    .login, and then have it killed by their .logout.  Program will not run
X    if a .planpid file, the file with the PID for plan, already exists in
X    the user's home Directory.

X
X    Cleaned up indenting, made PID stuff selectable via precompiler
X    directive. Added chmod, else it wouldn't work on my system. Made it
X    clean up old .plan and .planpid upon exit.  Made it fork, so one
X    doesn't need to run in the background.

X   Well, here is another update to the planner script that has been contributed
Xto by countless users that are all mentioned throughout the README file. I
Xhave certainly contributed the least to any of the code of this project,
Xbut was more concerned with putting some utility and functionality into it.
X   Hopefully people will continue to have more ideas that they can put into
Xthis. In case people are curious, I've logged approximately 30,000 finger
Xrequests to my account, and it's still as reliableas ever. I have looked
Xat all the available packages, and have to say that this seems to be the
Xsturdiest and "frilliest" package that is available. Basically lets you do
Xanything to your .plan that you could ever want. Check it out by fingering
X    [e-mail]
X
X   The change to this package that merits a repost is that it will no longer
Xhang your machine when a mirror host (NFS mounted volume) is fingered. Before,
Xthe .plan was a named pipe which pointed to a background process. However,
Xthis background process did not exist on other machiens that had the same
Xfile system, so it would just hang the finger daemon (bad). So, to get around
Xthis, the named pipe is placed in the /tmp disk, and a symbolic link to
Xthe .plan file is made (credits go to Fumiaki Kamiya). Then, people will
Xsimply get a "No Plan" message when they finger other hosts that do not have
Xthe resident background process.
X
X   People should also note that this is incredibly cpu-friendly. It gets the
Xhost-name of the machine that is fingering you through a simple step involving
Xnetstat (but only taking a head-20 of the output).
X
X   It shouldalso be noted that this will NOT run on ULTRIX, disabled finger
Xdaemons, or, of course, VMS. I would not recommend that any new users
Xwork with this, because it can definitely peeve your system administrator,
Xand because you will have to play with the code to get it working. To any
Xmoderate to advanced UNIX user, it should be quite easy - just take a bit
Xof tweaking. I haven't been able to figure out an easy way to make the code
Xuniversal, because there are so many places where you have to change pathnames,
Xusernames, etc. But, you should be able to get it running flawlessly in under
Xan hour at the very most.
X
X
XHoping you have fun with this, and hoping your New Year's Celebration was
Xas good as mine,
X
X
XSteve Franklin
