NEDI

The installation for Redhat/CentOS is similar (e.g. with postgres backend):

yum -y install perl-Net-Telnet perl-Socket6 perl-Algorithm-Diff perl-Net-Telnet perl-Net-SNMP net-snmp rrdtool perl-Net-SSH perl-RRD-Simple.noarch perl-Time-HiRes-Value.noarch perl-Class-DBI-Pg.noarch perl-DBD-Pg perl-IO-Pty-Easy.noarch perl-libwww-perl.noarch postgresql php-pgsql php-process




Generic Installation Procedure

1. Satisfy the dependencies listed below.
2. Extract the NeDi archive (e.g. to /var/nedi). Move the files in html to your webserver’s document root (e.g. /var/www/htdocs) or adjust the document root.
3. Edit nedi.conf to fit your needs (Please use the new one as copying your existing config may lead to errors, if new items are missing). If you get ‘Dude, where is nedi.conf?’ link it to /etc.
4. Cd to /var/nedi (or whatever you chose) and type ./nedi.pl -i to initialize the backend. Starting with NeDi 1.4, you can use -i nodrop for updating an existing DB structure without the need for DB admin credentials. Alternatively -i updatedb will do just that without any loss of data.
5. The monitoring daemon moni.pl can be started from commandline, startup script or the GUI.
6. Since syslog.pl requires a priviledged port (514) a simple workaround (to avoid running it as root) would be to forward a high port via system’s FW. This means something like this for Linux: iptables -A PREROUTING -t nat -p udp –dport 514 -j REDIRECT –to-port 1514. Just set $port in syslog.pl to 1514 (or whatever you chose the port to be). Now you can even restart it from the GUI with System-Services.
7. A similar setup can be implemented for snmptrapd: iptables -A PREROUTING -t nat -p udp –dport 162 -j REDIRECT –to-port 1162.
