Hi to all.. I have some questions about snmp related terminology.
So is it valid the term snmp server or is it better to use snmpd? I think some times networkes use the tem master and agent.. What is valid and what is not

well snmpd is one example of an snmp server...

generally an agent is what is providing the snmp data and the master is the central server that is recieving snmp traps and polling statistical data for it.

So when i query a maching with snmp commands then thats the agent right?

which "that" ??

snmpget -v1 -c public hostname .1.2.1...mpla mpla
the hostname is the agent? Right?

No. Hostname in that command refers to the server that's running snmpd. You are instructing your client 'snmpget' to retrieve information form the server called 'hostname'.

An agent is a software module that supplies data to snmpd.

so ip module of the snmpd is the agent right?

I have always considered snmpd an agent. If a device (router/switch/linux box/XP box) is running some version of snmpd, then it is considered to be a "managed device". In a typical scenario, all managed devices are controlled/monitored by a centralized network management station (NMS) using commands like snmpget, snmpset, snmptrap.

There are probably dozens of network management station software applications available. Some with a hefty price tag. If you want to try some of the open source apps available, then try MRTG or NAGIOS.

cool so the agent is the snmpd server
