snmpd.conf is not necessary. I've been running ucd-snmp on a dedicated
server since Nov '97 and have never needed it. SNMP uses mib-files for
its configurations.

SNMP will allow you to to read and write network information to any device
configured for it. We have over 150 devices on several lans that I monitor
from a singer server. I use mostly cgi's but I have a few scripts that I
run for tracking sensitive network info.

A good tool to get is mrtg ...

	http://ee-staff.ethz.ch/~oetiker/webtools/mrtg/mrtg.html

which will display a graphical representation of your network traffic.

Also, you can write your own programs (I use perl 5) and cgi's to
customize the system to your own needs. We track modem usage, bandwidth,
system performance such as system up time, cpu processes, disk usage, etc.
The list seems endless.

However, security is a big, big issue. The server that runs snmp here, is
accessible from internal office pc's and only 3 staff members from home
can access the information. Any network device monitored should have one,
two at the most, write hosts, and a handful of read hosts.
