How do I get nfsen 1.3.6p1 running on Fedora Server 25?


Works for me, your milage may vary, some cars not for use with some sets, if this doesn't work then the only thing I'll do for you is feel bad for you on a best-effort basis, yadda yadda…



# dnf groupinstall 'web server'
# dnf install nfdump libpcap-devel perl-Sys-Syslog rrdtool-perl.x86_64 perl-IPC-SysV perl-MailTools perl-Socket6.x86_64

Get, build and install >>fprobe.

Set up symlinks that nfsen wants:

# ln -s /usr/bin/nfcapd /usr/local/bin
# ln -s `which nfdump` /usr/local/bin
# ln -s `which nfprofile` /usr/local/bin

Set up the user account for nfsen:

# sudo useradd -G apache -d /var/lib/netflow netflow
# sudo chown netflow:apache ~netflow
# sudo chmod 750 ~netflow

Set a timezone in /etc/php.ini, the line will look something like

date.timezone = 'America/New_York'

Configure httpd:

  • create the file /etc/httpd/conf.d/nfsen.conf:
Alias /nfsen /var/www/nfsen
<Directory /var/www/nfsen/>
    DirectoryIndex nfsen.php
    Options -Indexes
    AllowOverride all
    order allow,deny
    allow from all
    AuthType Basic
    AuthUserFile /etc/httpd/conf/htpasswd.nfsen
    AuthName "Access"
    require valid-user
    AddType application/x-httpd-php .php
    php_flag magic_quotes_gpc on
    php_flag track_vars on

Get >>nfsen.

Configure nfsen.conf:

  • $BASEDIR (I change it to live in /var/lib/netflow/nfsen-1.3 so that if I ever have multiple versions I can keep them separate)
  • $WWWUSER/$WWWGROUP (change both to apache)
  • %sources (remove the two samples, add your flow(s)); example to match the fprobe example above:
    %sources = ( 'ns25-lan'    => { 'port'    => '999', 'col' => '#0000ff', 'type' => 'netflow' }, );
Edit the nfsen-provided file libexec/
  • on line 76, change the $rrd_version from 1.5 to 1.6
Install nfsen:

# <your-nfsen.conf-file>

Make nfsen start at boot time:

Create /etc/systemd/system/nfsen.service:

Description=NfSen Service

[Service] Type=forking PIDFile=/var/lib/netflow/nfsen-1.3/var/run/ ExecStart=/var/lib/netflow/nfsen-1.3/bin/nfsen start ExecStop=/var/lib/netflow/nfsen-1.3/bin/nfsen stop Restart=on-abort


...and enable it:

# systemctl enable nfsen

Start nfsen:

# systemctl start nfsen

Note that for me it spits out a whole barf-load of perl warnings, but it still appears to work.

Start fprobe (making sure it is aimed at the right port):

# /usr/local/sbin/fprobe -fip -i eno1 -e 120 -q 10240 probably want to include that in /etc/rc.local as well so that starts at boot time.

Set httpd to start at boot time:

# systemctl enable httpd

Start httpd:

# service httpd start should see something in 5 or 10 minutes.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
