CURRENT_MEETING_REPORT_ Reported by Michael Reilly/DEC Minutes of the Domain Name System (DNS) The primary purpose of this meeting was to discuss the DNS MIB and issues related to its development. The following topics were put up for discussion: o Grouping of the Objects o Selection of Object to include o Read-write status of the Objects o Additional Objects to include An early draft was handed out to focus discussion. It contained all of the groups currently proposed as well as many of the objects for each of the groups. One of the first items was a discussion of what imperative operations would be allowed via SNMP. After some discussion we agreed to include an object which would tell the server to do a zone update now. It was also agreed that we would provide a mechanism which would allow for cache entries to be removed - this may be accomplished by setting the TTL to zero for the specified entry. There was a strong desire to have the cache table have an entry for the source of the cache information to aid in debugging. The most difficult subject was whether to allow SNMP to add or modify records in permanent storage (i.e., not just in cache). Since the exact sequence of events to take place on a server when a record is modified was never specified, it is difficult to write MIB elements until this is understood. It was agreed that Bob Austein would attempt to write up the ``rules'' which define the sequence of steps to be taken when an actions such as the creation of an A record is specified. Jon Saperia will work with Bob to write a set of corresponding MIB objects which reflect these ``rules''. There was also a discussion of how various counter information would be tabulated in the MIB. Several of the requests were to be able to see request not only by record type, but also by: o Requests via UDP o Requests via TCP o Number of local requests o Number of remote requests In addition to these ``cuts'' at the data, several suggestions were made about the specific items to count. There are now lists of counters suggested by both Win Treese and Phil Almquist. They will be reconciled 1 and put into the appropriate counters groups in the next version of the MIB which will be posted to the mailing list. Bob Austein also brought up the general issue of how to deal with the changes that may be coming up in IP addressing and subnet mask sizes. He will work on some ideas an present that information to the Working Group for discussion. The group expressed a desire for the mailing list for the Working Group to be the namedroppers mailing list.
