Annotation of 43BSDTahoe/etc/named/CHANGES, revision 1.1.1.1

1.1       root        1: 
                      2: Welcome to version 4.8 of bind.
                      3: 
                      4: There have been several changes to the named boot file (/etc/named.boot)
                      5: of which you should be aware.  The "domain" line for each zone is no longer
                      6: needed, but one such line may still be used to specify a default domain
                      7: to be used for queries containing names with only a single component.
                      8: The term "suffixes", which was added in version 4.7alpha, has been removed.
                      9: 
                     10: The manual page on named (named.8) has been updated to reflect all
                     11: these changes.  Please read this and look at the example files
                     12: before installation.  You should also note the changes in the
                     13: resolver code to support non-fully-qualified addresses and per-user
                     14: host aliases.  See hostname(7) for an overview.  Two new routines
                     15: have been added to the resolver library since the last test release:
                     16: res_query formulates a query, sends it, waits for a response and does
                     17: preliminary error checking; res_search implements the search rules
                     18: of gethostbyname using res_query.
                     19: 
                     20: The MX lookup routine in sendmail has been modified to use res_search.  
                     21: Also, dn_skip takes an additional parameter and has been renamed
                     22: to dn_skipname.  While old sendmail binaries will work with the new
                     23: version of bind, because of these changes, it is desirable to install
                     24: new sendmail sources and recompile sendmail.  Do not rebuild sendmail 
                     25: from old sources.   The new sendmail is on ucbarpa.Berkeley.EDU for
                     26: anonymous FTP from pub/4.3/sendmail.MX.tar and pub/4.3/sendmail.MX.tar.Z.
                     27: 
                     28: There have been numerous changes to named, fixing most of the known
                     29: bugs that can be fixed without major structural changes in the server.
                     30: Several server configurations that failed before should now work.
                     31: Certain robustness problems have been fixed, in particular bounds-
                     32: checking when processing incoming packets.  Two changes have been made
                     33: in preparation for negative caching: SOA records are sent in the authority
                     34: section in negative responses with NXDOMAIN set, and a bug was fixed that
                     35: caused confusion and repeated requests if a response had no error, no answer
                     36: and an SOA in the authority section.  As such responses are already sent
                     37: by other servers, and will be sent by the next release of BIND, it is
                     38: important that all sites upgrade to this version as quickly as possible.
                     39: 
                     40: The root "hint" cache and cache file remain the largest problem area,
                     41: along with named's naivete in accepting bogus server's data.
                     42: These will be addressed in the next release, along with asynchronous
                     43: zone transfers, intelligent reloading of zone files, faster startup,
                     44: and caching of negative responses.
                     45: 
                     46: This version (4.8) will replace the last officially released version (4.5).
                     47: Version 4.5 has a serious bug that causes the generation of a continuous
                     48: stream of bogons to the root domain servers (bogus queries with the query
                     49: response bit set and possibly garbage for nsid and rcode).  It is imperative
                     50: that these versions of named be replaced as fast as possible.  We urge you to
                     51: field 4.8 quickly, for the sake of the root domain servers.
                     52: 
                     53:        Mike Karels
