SNMP Network Auditor is a small collection of Perl scripts that can be used to scan an arbitrary set of networks, defined in a configuration file, and identify any nodes which are running an SNMP service on a user-specified UDP port (default 161) with a user-specified community string (default public). The results of the scan can be saved in a text file and/or in a formatted HTML report. The report is broken down by network, and includes the system.sysDescr.0 attribute returned by each detected node.
