Is there? I think you need to narrow that definition down a little:
There do exist ubiquitously used default community strings for SNMP
access. The kicker: This only goes on devices and agents that support
SNMP. SNMP is not universally supported by any measure[1], and no SNMP
support means no SNMP passw^Wcommunity strings.

On FreeBSD, there is no built-in default SNMP support, but you can add
it by installing, for example, the net-snmp port. That port comes with
documentation that explains in detail how to configure it, including
setting community strings. But remember: The easiest way to secure
SNMP is by not enabling it. So no-action might be more secure than
any-action-at-all. Are you sure you want to go ahead and install SNMP?
[1] Example: switches. ``managed'' means ``configurable'' and ``snmp
support''. If it's not managed it's just a dumb packet passer. If it
is it'll keep statistics and such. Nevermind that you really don't
want to build any network of more than two switches in size without
it. You pay extra to get it.
