NAME
       smokeping_install - How to install SmokePing

OVERVIEW
       This document explains how to setup SmokePing at your
       site.

DESCRIPTION
       Prerequisites

       SmokePing does not stand alone. It relies on various other
       tools and services being present. Apart from a Unix OS and
       a working Perl installation you need the following things.
       The list contains the names of the tools together with the
       version of the tool which I am using, and a link for down-
       loading the tool.

       RRDtool 1.0.33
           http://people.ee.ethz.ch/~oetiker/webtools/rrd-
           tool/pub/rrdtool-1.0.33.tar.gz

           Just follow the installation instructions. We need
           this package todo all the logging and graphing in
           SmokePing.

       FPing 2.4b2
           http://peo-
           ple.ee.ethz.ch/~oetiker/webtools/smokeping/pub/fping-2.4b2_to.tar.gz

           This is a special version of fping which actually
           builds. I have not modified the code in any way, I
           just fixed the autoconf setup. The original can be
           found on http://www.fping.com/down-
           load/fping-2.4b2.tar.gz

           Note that fping must be installed setuid root. It
           seems that older versions of fping report round trip
           times in 0.1 milliseconds instead of 1 milliseconds as
           advertised ... SmokePing tries to figure this out. It
           tells you when it starts ... let me know it it gets it
           wrong.

       Webserver
           http://httpd.apache.org/

           Well I wont get much into this. The important thing
           is, to have a webserver which allows you to run CGI
           scripts. If you are using Apache I strongly recommend
           using the suexec system for running CGI scripts. Often
           it is sufficient to change the suexec binary to setuid
           root and restart Apache.  Using suexec allow to run
           cgi scripts under proper user accounts.

       Perl 5.6.1
           http://www.perl.com

           I guess you will get away with older versions of perl.
           I am using 5.6.1 here and it works fine.

       SpeedyCGI
           http://daemoninc.com/speedycgi/

           SpeedyCGI speeds up CGIs written in perl dramatically
           by making them memory resident and handing new request
           to the script which is already running.  SmokePing has
           been optimized for use with SpeedyCGI. Note that you
           do NOT need mod_speedy, just the plain and simple
           speedy executable, this is the beauty of this tool it
           works without touching your apache ...  Otherwise you
           could as well be using FastCGI or mod_perl.

       Installation

       Once the tools listed above are in place, you can start
       setting up SmokePing itself. Once the SmokePing tools are
       unpacked, they are more of less ready to use. At least to
       the extent, that it is not necessary to install them.  You
       may want to rename the directory to a name which does not
       contain the version number of SmokePing, or at least make
       a symlink, so that you can use a persistent name when
       referring to SmokePing files.

       In the distribution you find a number of files named
       *.dist they have to be edited and renamed to *. Below you
       find a short explanation for each of the files you have to
       edit:

       bin/smokeping
           Make sure all the required libraries are available and
           the first line of the script points to your copy of
           perl. Adjust the use lib lines to point to your RRD-
           tool installation and to the Smokeping/lib directory
           and edit the path of the config file to be in sync
           with reality.

       htdocs/smokeping.cgi
           Edit the smokeping.cgi analog to the smokeping script
           above. Make sure the first line of the script is
           pointing to your freshly installed copy of Speedy CGI.
           Store the script in a directory of your weberver where
           CGIs get executed. You also have to edit the use lib
           line similar to what you did to smokeping

       etc/config
           Create your SmokePing configuration file. The easiest
           is to copy the etc/config file and work from there.
           Please refer to the smokeping_config manpage for
           details.

       etc/basepage.html
           Edit the html template to your likings. Please do not
           remove the link to the SmokePing counter and my name
           from the template.

       etc/smokemail
           If you are going to use the DYNAMIC IP support, cus-
           tomize the contents of this file.

       Now you are ready to start smokeping:

        ./bin/smokeping

       Once the system works, you may want to put a SmokePing
       startup script into your /etc/init.d tree. Check out the
       smokeping manpage for further information.

       When you can now also open the smokeping.cgi webpage to
       look at your data.
