snmp installation

Hi,
I am new to snmp. I am using debian lenny in all my systems. I want to monitor the systems which are in network already. At begining i do not want to implement snmp in routers or in any switches. So i chose one system in my network and installed snmp,snmpd.

I didn't change any settings in the configuration file snmpd.conf. I got some lines of output while using snmpwalk command with 'localhost'. Now i want to get informations from other systems which are in network.

   What shall i do for that?

regards,
Raja Pandi
