[CentOS] connection refused resolving - after 5.4 upgrade
Hi all, prior to 5.4 upgrade, my two DNS servers would only get 'connection refused resolving .....' on rare infrequent occasions (once or twice a month) after upgrade to 5.4 I get 500+ per day. Google has suggestions for |logging category lame-servers null; ; ; |however this strikes me as severe overkill as it will mask genuine problems. Anyone else noticed this? Suggestions as to why or what is causing? Thanks Rob -------------- next part -------------- A non-text attachment was scrubbed...

[CentOS] connection refused resolving - after 5.4 upgrade
Hi, We see the same thing. Massive amounts of entries in Logwatch report. Is logging lame servers to /dev/null the answer here ?

The question I have is how do I locate the actual trigger - I prefer to fix things at the cause, not mask somewhere down-stream. The only item I can see is the log message coming from named in my messages log. Any ideas appreciated - TIA Rob -------------- next part -------------- A non-text attachment was scrubbed...
