5. It installs the graphics-engine software in the ourmon bin directory.
6. It creates log directories as needed.
7. It installs the supplied Web pages in the system ourmon Web 
directory.
Before you run 
configure.pl
, spend some time going over the configuration
tips in the next section.
Ourmon Install Tips and Tricks
When you use 
configure.pl
to install the ourmon software, there are a couple of
important things you should know first:
1. Know the name of your Ethernet interface.The 
configure.pl
script will
try to guess, but it may get it wrong. For example, on FreeBSD it
might be em0. On Linux it might be eth1.
2. If it makes sense to have a home/mask network, then change the
default supplied by the script. For example, you might have net
192.2.0.0/16, so put that in. If you don’t do this, you can always fix it
later by changing etc/ourmon.conf and rebooting the probe.
3. When you install the graphics-engine software,
configure.pl
wants to
know where it should put the supplied Web files that arrived when
you unpacked ourmon and also where runtime-generated Web files
should be put.This is the external Web directory that you need to
make available to the Web via the (Apache) Web server. Web server
configuration, which is beyond our scope, is needed to make that
happen. Depending on which UNIX distribution you choose, your
Apache Web server will have a global htdocs directory. For example,
with FreeBSD is could be /var/www/data.You need to know where
this directory is located before running 
configure.pl
.
Configure.pl
will
take your supplied Web server directory and append ourmon to it
(thus making the directory /var/www/data/ourmon in the file system
and http://yoursystem/ourmon available on the Web). Supplied Web
files and generated files at runtime (barring log files) will all be put in
that directory.Typically, any Web server has a default data directory
