  $ man snmpcmd

  SYNOPSIS
       snmpcmd   [OPTIONS]  AGENT  [PARAMETERS]

  OPTIONS
      -c  community


So the first error you make was to forget the '-c' flag
before the community name. The command ought to have been:

     snmpget -c communityName   ipaddress

That's why you got the error message "Unknown host"
(It was treating "communityName" as the host)

It's also sensible to specify the version of SNMP you want to use:

    snmpget -v1 -c communityName  ipaddress



The final thing you've forgotten is what information you are trying to get.
You need to specify what you are interested in/

So the full command is actually of the form:

    snmpget -v 1 -c communityName  ipaddress  OID



> especially referring to OIDs (how I determine them?)

Well, what are you interested in?
If you want to know the operating system information, you
could run

    snmpget -v 1 -c public  127.0.0.1   sysDescr.0


It might be easier to start with "snmpwalk" rather than "snmpget".
That works in basically the same way, but is a little more forgiving
in what it returns.
