This archive contains Perl 5 modules SNMP_Session.pm and BER.pm, which, when used together, provide rudimentary access to remote SNMP (v1) agents. This module differs from existing SNMP packages in that it is completely stand-alone, i.e. you don't need to have another SNMP package such as CMU SNMP. It is also written entirely in Perl, so you don't have to compile any C modules. It uses the Perl 5 Socket.pm module and should therefore be very portable, even to non-Unix systems. The SNMP operations currently supported are "get", "get-next", and "set", as well as trap generation and reception. For an excellent example of the type of application this is useful for, see Tobias Oetiker's ``mrtg'' (Multi Router Traffic Grapher) tool.
