Interesting.. does it survive getting out of the squid tree and move onto the
next OID? i.e. what does squid return for a get-next on its last object, and
does net-snmp handle that case?
Unfortunately not, but for another reason. Squid's SNMP agent code
(built into
the Squid application) returns some table entries in non-lexical order,
which breaks
the walk inside of Squid's MIB. One table is indexed by the IP address,
but Squid
always returns the entry for 127.0.0.1 first, regardless of the IP
address of the
server.
