Netdisco hämtar MAC-tabeller, ARP-tabeller, VLAN-databaser, LLDP/CDP-grannskap, firmwareversioner, m.m från routrar och switchar med hjälp av SNMP. Man schemalägger när data ska samlas in.
Installation Ubuntu 14.04.1 LTS Server x64
Förberedelser
Denna guide är till stor del hämtad från: http://blog.asiantuntijakaveri.fi/2014/08/netdisco2-on-ubuntu-1404.html
sudo su - apt-get update && apt-get -y dist-upgrade && apt-get -y install open-vm-tools build-essential wget lftp mtr-tiny zip ntp
Databas
apt-get -y install libdbd-pg-perl libsnmp-perl postgresql pgtune mv /etc/postgresql/9.3/main/postgresql.conf /etc/postgresql/9.3/main/postgresql.conf.old pgtune -i /etc/postgresql/9.3/main/postgresql.conf.old -o /etc/postgresql/9.3/main/postgresql.conf
Switch to postgres user and create new SQL user
su - postgres createuser -DRSP netdiscoUSER Enter some password here createdb --owner netdiscoUSER netdiscoDB
Switch back to root
exit
Netdisco
adduser netdisco --shell /bin/bash --disabled-password --gecos netdisco && su - netdisco curl -L http://cpanmin.us/ | perl - --notest --local-lib ~/perl5 App::Netdisco
mkdir ~/bin
mkdir ~/environments
ln -s ~/perl5/bin/{localenv,netdisco-*} ~/bin/
~/bin/netdisco-daemon status
Här är grunden för deploymenten, lägg till de SNMP-communitys som ska användas. Schemaläggningen är i cron-format. T.ex. discoverall görs 10 över varje timme.

Switch back to root
exit echo "( sudo su - netdisco -c '/home/netdisco/run-netdisco.sh' ) &" >/etc/rc.local reboot
