Style Cleanup Required
This article does not follow the style standards in the Wiki Guide. More info...

1. Install dependencies:

sudo apt-get install apache2 libapache2-mod-php5 mysql-server libnet-snmp-perl php5-mysql libnet-telnet-cisco-perl php5-snmp php5-gd libalgorithm-diff-perl rrdtool librrds-perl

Note: The command listed above needs to be on one line

2. Setup SSL on the Apache2 webserver:

IMPORTANT – You should always use SSL because Nedi contains a great amount of information about your network. Here is a great step-by-step tutorial on How to setup SSL in Ubuntu

3. Download Nedi:

wget http://www.nedi.ch/pub/nedi-1.0.8.tgz

4. Uncompress and extract the archive:

tar -xzf nedi-1.0-rc6.tgz

5. Move Nedi directory to /opt and fix permissions:

sudo mv nedi /opt/
sudo chown -R www-data:www-data /opt/nedi
sudo chmod 775 /opt/nedi/html/log/

6. Create a link to the webserver root:

sudo ln -s /opt/nedi/html/ /var/www/

7. Create a link to the configuration file:

sudo ln -s /opt/nedi/nedi.conf /etc/nedi.conf

8. Create a MySQL database password:

sudo mysqladmin -u root -p password "YourPasswordGoesHere"

9. Initialize the Nedi database:

cd /opt/nedi/
./nedi.pl -i

10. Answer these prompts:

  • MySQL admin user: root
  • MySQL admin pass: <enter the password you created in step #8>

11. Edit /opt/nedi/nedi.conf:

  • List your SNMP read-only passwords (one per line)
  • List your telnet usernames and passwords (one pair per line)

12. Optional - Edit /opt/nedi/seedlist and add your network devices:

List the IP addresses of your devices (one per line)

13. Restart the webserver (Apache2):

sudo /etc/init.d/apache2 restart

14. Run a discovery of your network and gather your device configurations

cd /opt/nedi/
./nedi.pl -pob

15. Login to your Nedi website:

User: admin
Password: admin
IMPORTANT - Change the admin password NOW!

16. Create a script to start/stop Nedi:

nano /opt/nedi/startnedi.sh

17. Paste this text into that file:

#start nedi from crontab. Creates logfiles
CMD="./nedi.pl $opts"
cd /opt/nedi
now=`date +%Y%m%d:%H%M`
echo "#$now start # $CMD" > $LASTRUN
echo "#$now start" >> $LOGFILE
tail -8 $LASTRUN >> $LOGFILE
now=`date +%Y%m%d:%H%M`
echo "#$now stop" >> $LOGFILE
echo "#$now stop" >> $LASTRUN'

Press “Control-O” and then “Enter” to save these changes.

18. Make “startnedi.sh” an executable file, and create a directory to hold Nedi log files:

chmod +x /opt/nedi/startnedi.sh
sudo mkdir /var/log/nedi
me=`whoami`;sudo chown $me:$me /var/log/nedi

19. Schedule Nedi to run periodically (every 4 hours) using cron:

crontab -e
15 */4 * * * /opt/nedi/startnedi.sh  # Discover and gather device configurations

Press “Control-O” and then “Enter” to save these changes.


Create a file in /etc/cron.d/ containing this information:

15 */4 * * *    root   /opt/nedi/startnedi.sh  # Discover and gather device configurations

Both of these methods will cause the script to run every 4 hours at :15 past the hour beginning with 4:00am.
