Dear Friends In my Fedora core 6 box installed squid-3.0.STABLE8 by it's source in port 8080 and squid-2.6.STABLE13-1.fc6 installed by it's rpm in port 3128. I had to do go for that option according to my requirement. anyway this set-up is working very well. DNS taken form /etc/resolve.conf But after few days suddenly there was a following error in squid-3.0.STABLE8's cache.log. Performing DNS Tests... FATAL: ipcache_init: DNS name lookup tests failed. Squid Cache (Version 3.0.STABLE8): Terminated abnormally. Obviously most of the requests were failed . This is happened only in squid-3.0.STABLE8. No errors in squid-2.6.STABLE13-1.fc6. I found a solution as I hard corded DNS name server in squid.conf and it's started to work. my question is , why this type of abnormal behaviour happens in squid-3.0.STABLE8? Can somebody direct me to a solution please. Many Thanks Shaine. -- View this message in context: http://www.nabble.com/DNS-name-lookup-tests-failed.-tp18902315p18902315.html Sent from the Squid - Users mailing list archive at Nabble.com.
