For starters....I would try and get a different box. NTOP can be resource 
intensive, and you probalby don't want to kill a box that is Mail, Web, and 
Proxy for your company. Then you can play around to figure out how to make it 
work without fear of breaking a required box. Also, you will find that running 
too much with NTOP is a bad thing.

Subject: [Ntop] ntop and rrd graphics on Red Hat 7.3
 

Hey everyone, I need some serious help, I'm kinda of linux noob and an
ntop noob. I installed ntop ver.2.2 on an Redhat 7.3 box that we use as a
Web, Mail and Proxy server.
 At first the problem I had is that every time the rrd plugin tried to
start it said it couldn't create the /var/top/rrd directory, so after
downloading the rrdtool and getting nowhere I went a head and created the
directories manually, that is the :

/var/ntop/rrd
/var/ntop/rrd/flows
/var/ntop/rrd/interfaces
/var/ntop/rrd/graphics

Gave them the respective user rights and voila the plugin now ran ok. Now
I get an error that has to do with the libpng library it says something
like this:

program was compiled using the png.h on package libpng-1.2.4
program using the png.c file on installed package libpng-1.0.2

The something about incompatibility because of this and a fatal error, and
then ntop shuts down. I've tried to look for an rpm package that lets me
upgrade the libpng library but haven't succeeded. I compiled a
libpng-1.2.8rc5 but I don't know how to make it work, because it still
detects the old libpng-1.0.2.

Like I said I'm new to this and my boss just said make it work, I'd
appreciate any help I can from any good soul out there that has compasion
for nooobs. If anyone can tell a surefire way to get it up and running
with the graphics please help me out.

Thanx!
