Hrmm.. how about putting a packet sniffer like tcpdump or ethereal on the remote computer and then having it log the data back to a console? AFAIK, that'd be the only way.

Then what is that snmp and oid stuffs... ?
do you have any idea?

You mean Simple Network Management Protocol?

This document describes an architecture for describing Simple Network Management Protocol (SNMP) Management Frameworks. The architecture is designed to be modular to allow the evolution of the SNMP protocol standards over time. The major portions of the architecture are an SNMP engine containing a Message Processing Subsystem, a Security Subsystem and an Access Control Subsystem, and possibly multiple SNMP applications which provide specific functional processing of management data.

<snip>

An SNMP management system contains:

- several (potentially many) nodes, each with an SNMP entity containing command responder and notification originator applications, which have access to management instrumentation (traditionally called agents);

- at least one SNMP entity containing command generator and/or notification receiver applications (traditionally called a manager) and,

- a management protocol, used to convey management information between the SNMP entities.

Read the rest of the RFC Standard 62 for more indepth details. IIRC, this isn't sniffing but rather information on the machine status.
