your Linux distribution is based on the RPM (RedHat Package Manager)
packages, so it is quite simple to install any tool you want. Also the
ucd-snmp tool is available as RPM package - and more, it is part of your
RedHat distribution. ;)

After " rpm -ivh ucd-snmp-* " check /usr/doc/ucd-snmp-....  and, of course,
the man pages, specially "man snmpd.conf".
Except the individual system information you can use this snmpd config file
on any machine in your network.

You need to edit at least one small config file, then launch the snmpd demon
by running " /etc/rc.d/init.d/snmpd start " as root. If you want launch snmpd
automaticly with the system, use the chkconfig or any other SystemV /
runlevel editor to add snmpd.

did you configure and launch the snmpd daemon ?? If you are not certain,
check it with "ps awx | grep snmpd".

please read the mrtg config manual to understand this error message.

same in the Cisco router: without activating the snmp service the router
don't know how to answer snmp requests on port 161. ;-)
