# Ugly hack because libexec/NfProfile.pm needs to be rewritten before a DESTDIR variable will work in install.pl.
# But unlike the perl modules, the profiles have no embedded path information so to solve the problem I made
# no modifications to install.pl in profile sections.  I just backup the .conf file, set the profile directories
# to point to destroot, and after the install replace the previous .conf file that points to profiles in PREFIX.
# Yuch!  I've asked the developers to add DESTDIR support in a future version.

ui_msg "\n **** To complete the nfsen installation ****

To complete the nfsen installation follow the steps below.  Read the documentation
at http://nfsen.sourceforge.net for operational instructions.


1) Install PHP (not covered).

2) In ${prefix}/etc, rename the file nfsen-dist.conf to nfsen.conf to make it ready
   for use; the file paths are already set for MacPorts.  Edit it and insert the
   netflow sources you need, and run this command to setup source, RRD, and profiles:
        nfsen reconfig
 
3) Start nfsen manually to test the configuration.
        nfsen start

   NOTE: nfsen starts nfcapd (nfdump utility) automatically to capture netflows from your devices
         based on the sources listed in nfsen.conf.

4) Start nfsen with the startup script after verifying configuration
        sudo launchctl load -w /Library/LaunchDaemons/org.macports.nfsen.plist

5) Check the nfsen web interface at http://localhost/nfsen/nfsen.php
