For those that may have this issue in the future, here is the guide I
worked up with the help of several other online guides to get this
installed and running properly on Ubuntu. The steps should work on
almost any Debian Linux as well I would think. Hopefully this will help
some people down the road.
== Step 1 ==
Install some of the precompiled packages from the repository. There are
a few more available, but it is better to build them from source so we
can specify a few more options with them than what comes with the
repository. We also need a C compiler and some development packages for
nfdump to compile correctly, so we get them as well.
sudo apt-get install rrdtool librrds-perl perl5 flex php5
libmailtools-perl libapache2-mod-php5 gcc librrd-dev
== Step 2==
Next we need to download both nfsen and nfdump.
http://sourceforge.net/projects/nfdump/
http://sourceforge.net/projects/nfsen/
sudo wget
http://sourceforge.net/projects/nfdump/files/stable/nfdump-1.6.1/nfdump-1.6.1.tar.gz/download
sudo wget
http://sourceforge.net/projects/nfsen/files/stable/nfsen-1.3.4/nfsen-1.3.4.tar.gz/download
== Step 3 ==
Since both of these download are in .tar format we need to unpack them.
tar -xvf nfsen-1.3.4.tar.gz
tar -xvf nfdump-1.6.1.tar.gz
== Step 4 ==
After this we need to make and install these packages, first we want to
make nfdump. Change directories to the nfdump download
cd ./nfdump-1.6.1
=== Step 4.1 ===
We need to make sure that nfdump can run the make files so first we need
to configure it. We need to enable nfprofile so we
can make new profiles other than live. If this runs successfully, then
we can make the install files and install them.
sudo ./configure --enable-nfprofile --enable-sflow
sudo make
sudo make install
== Step 5 ==
If all of these have run successfuly then we can move onto installing
and setting up nfsen. First make a directory for nfsen to store all of
it's data in. We will also have to change it's owner and it's group so that
nfsen can write and read to the file. We can set the owner and group to
www-data which is the Debian version of the apache user. We also need
to modify the permissions on the folder.
sudo mkdir /data
sudo chown www-data /data
sudo chgrp www-data /data
sudo chmod 775 /data
== Step 6 ==
Now we can change directories to nfsen and move forward from there.
cd ..
cd ./nfsen-1.3.4
=== Step 6.1 ===
We need to change the name of the nfsen options file and edit it to fit
our needs.
sudo cp ./etc/nfsen-dist.conf ./etc/nfsen.conf
sudo nano ./etc/nfsen.conf
=== Step 6.2 ===
Now we need to change the file a bit to meet our install needs. The
most important ones to change are the $USER, $WWWUSER, and $WWWGROUP.
The others can be modified to what you want, this is just where I have
chosen to install nfsen.
$BASEDIR = "/data/nfsen";
$BINDIR="/usr/bin";
$USER = "www-data";
$WWWUSER = "www-data";
$WWWGROUP = "www-data";
=== Step 6.3 ===
Still in the nfsen.conf we add in our sources of netflows so it knows
what ports to listen on. Keep in mind there is a 19 character limit on
what you can specify for source names. Each new source needs it's own
unique port number to listen on.
# Netflow sources
# Define an ident string, port and colour per netflow source
#
# Required parameters:
# ident identifies this netflow source. e.g. the router name,
# Upstream provider name etc.
# port nfcapd listens on this port for netflow data for this source
# set port to '0' if you do not want a
collector to be started
# col colour in nfsen graphs for this source
#
# Optional parameters
# type Collector type needed for this source. Can be 'netflow'
or 'sflow'. Default is netflow
# optarg Optional args to the collector at startup
#
# Syntax:
# 'ident' => { 'port' => '<portnum>', 'col' => '<colour>',
'type' => '<type>' }
# Ident strings must be 1 to 19 characters long only, containing
characters [a-zA-Z0-9_].
%sources = (
'upstream1' => { 'port' => '9995', 'col' => '#0000ff', 'type' =>
'netflow' },
'peer1' => { 'port' => '9996', 'IP' => '172.16.17.18' },
'peer2' => { 'port' => '9996', 'IP' => '172.16.17.19' },
);
You can change the colors later on within nfsen but those changes won't
be reflected in this file. And whenever you use that source for a
different profile it will revert back to it's color in this file. So
makes things a bit easier on yourself and choose the colors as you enter
them in. It is a massive pain to change them from the web UI.
=== Step 6.4 ===
Now that this file as been edited to fit our install needs, we can
install nfsen on our server.
sudo ./install.pl etc/nfsen.conf
== Step 7 ==
Next you will probably need to restart the apache server so that you can
get to your new netflows collector. You may also need to tell nfsen to
start after this install has taken place for the first time.
sudo /etc/init.d/apache2 restart
sudo nfsen stop
sudo nfsen start
=== Step 7.1 ===
Now you should be able to get to your collectors web site.
http://(Domain-or-IP-address)/nfsen/nfsen.php
== Step 8 ==
Congratulations you now have a working nfsen server. Last, we'll want
to set up nfsen to start automagically whenever the server is rebooted.
We'll need to make a startup script.
sudo nano /etc/init.d/nfsen
#!/bin/sh
nfsen start
=== Step 8.1 ===
Now we'll want to get the script to run at start time and change it so
it runs a bit earlier than other things that may get in the way. We
also need to make it exacuteable.
sudo chmod +x /etc/init.d/nfsen
sudo update-rc.d nfsen defaults
cd /etc/rc2.d/
sudo mv S20nfsen S10nfsen
cd /etc/rc3.d/
sudo mv S20nfsen S10nfsen
cd /etc/rc4.d/
sudo mv S20nfsen S10nfsen
cd /etc/rc5.d/
sudo mv S20nfsen S10nfsen

I believe I worked out what was causing my issues.
The the folder that nfsen was installed in belonged to root. So I
changed the user and the group of the folder over to www-data
(Ubuntu's apache user) and it began to work fine for me. I modified
the nfsen configuration to run under the www-data user as well.
If interested I can post my step by step guide I worked up for Ubunutu
to get it running.

Hello,
I have the problem you mentionned in the first part of your email. My live pipe
is populated
and displays data, but my profiles, whatever theirs configuration are (shadowed
etc...), are not populated.
I'm currently running Ubuntu 9.10 as well and NfSen 1.3.4. NfProfile and NfDump
seems to be working fine.
Any help would be much appreciated.
Benjamin,
