Unexpected rcode code#

The two categories you would be interested now are resolver and queries (see BIND9 logging). You could configure your BIND for more verbose logging, but it's recommend to separate the files per category, as some of the categories are really excessive.

Because by default only the errors gets logged, there wouldn't appear a log line telling you this. It's also possible that the problem was solved immediately by simply moving to the next authoritative name server: there should always be at least two, in case one fails. The amount of occasions from 1 to 4 times for each also suggests the same. dig 133.61.208.88. it has probably been temporary. If there's no error now (confirmed by e.g. These entries were parsed from the syslog file on your recursive name server. Using aggregate zones instead of many separate might help see Using SORBS. SORBS may refuse queries if there are too many in too short period. IN queries to check against SORBS Listings. PTR queries for HELO mismatch checks etc.In BIND, see options like allow-query or in recursive servers allow-recursion.ДЄ common denominator here is most likely an SMTP server performing DNS based measurements against spam: This is most likely an access configuration problem: for some reason you are not allowed to perform the query. Server may not wish to perform a particular operation (e.g., zone To provide the information to the particular requester, or a name See your logs for further investigation.ДҐ Refused - The name server refuses to perform the specified If this is permanent, check network connectivity including firewalls, first. This is exactly why we have multiple DNS servers, if one is temporarily unavailable. Values have the following interpretation:Дў Server failure - The name server was unable to process this query

Response code - this 4 bit field is set as part of responses. The entries look like these to be more exact: named: error (connection refused) resolving '/A/IN': 62.75.191.6#53 Thank you so much once again and appreciate your help.

The entries in logs for my Bind9 server are generated in my syslog file as I haven't created a separate log file for my Bind9 yet. These entries come from the logs that Logwatch emails me on a regular basis. This is my name server, Bind9 that I run, maintain, and use. (serfail) means that my name server was unable to process the query when clients asked for it / or was I a client here and my query failed? (refused) means that my name server refused to provide information to a requester / or I am the requester here and I was refused? Simply look at the end of the previous line: '53' and search this address in your named configuration fil Eit should be located. However, I still cannot seem to get it straight. NAMEDXXXXXX: Unexpected RCODE (refused) resolving ' xx.xx.xx.xx.in-addr.arpa/ptr/in ': 53 This was probably because you had a forwarder in your nf that refuse your requests. What does those mean? What is mis-configured here? Please, note that it does not say 'resolving errors' or something after refused and serfail. I'm assuming you might need some config info, if so please let me know what and I'll get it for you. I don't really know where to start with these.
