I've no idea what commands Apple might provide, but I would
expect "sudo snmp" to give the error "command not found".
We don't include a command called "snmp".
Three fairly specialised error messages might indicate problems
with individual MIB modules, but shouldn't kill the whole agent.
If nothing else, you ought to be able to query the system group.
But since you haven't given any details of what snmpget
or snmpwalk command you've tried, it's impossible to know
what might be happening.
As regards to your config file.
> # snmpd.conf
> #
> # - created by the snmpconf configuration program
<shudder>
> rwuser admin
> rwuser private
> rouser public
You should probably check whether these users have been created
in the file /var/net-snmp/snmpd.conf. Defining a r{ow}user line
does *not* automatically create the user. This has to be done
explicitly. See README.snmpv3 for details.
> rocommunity public default .1.3.6.1.2.1.1.4
> rocommunity public
> rocommunity public
Three lines, listing the same community string?
That's one of the reasons that I don't like "snmpconf"!
Get rid of the first two.
(Unless you explicitly want to limit queries to just 'sysContact'
and nothing else!)
> rwcommunity private
> rwcommunity private
Get rid of one of these (and change
"private" to something less guessable!)
> syslocation Right here, right now.
> syslocation server_room
> syslocation ite225
> syscontact Administrator <[email protected]>
> syscontact [email protected]
Again, there's no point in having multiple copies of these
directives. Decide which value you want to use, and
get rid of the others.

If you're using the r[ow]{comunity,user} approach,
then get rid of these lines. They'll just confuse the issue.
