SNMP : Simple Network Management <strong>Pro</strong>tocol<br />

SNMP is a network equipment management protocol that allows the administrator to ask its equipment<br />

to gather information. In our example, we have found four equipments on our network which figured in<br />

the “public” community string, which means that anyone can have access to the information that the<br />

equipments send back.<br />

On the Internet, you can find the tools that can make these requests automatic.<br />

Note: the “public” community string is generally the value given by default to a machine running an<br />

SNMP agent. It is up to the administrator to modify its configuration. The opposite <strong>of</strong> a public string is<br />

a “private” string. This one does not authorise the delivering <strong>of</strong> any information to the general public.<br />

TELNET<br />

This service, which enables a remote access to a shell on the system, is generally restricted by a<br />

compulsory identification with login and password. The banner on the system can however be useful.<br />

Use telnet to connect yourself. By default, you are connected to port 23, so it is not necessary to<br />

specify any port.<br />
