problems with snmp and unix/linux desktops/servers

Hi folks,

I've to monitor servers/desktops debian and freebsd, but I've problems with snmpd.conf (I've configured that, but it doesn't work as I would).

Could you show me an example of snmpd.conf for freebsd and for debian, if you please?

Thanks for your support, any advice will be appreciated
Regards
Andrea
