There are many lines below. Can I ignore them? Jul 31 04:21:58 localhost named[19893]: client 127.0.0.1#41130: query (cache)...
Thanks falko I have set DNS in /etc/resolv.conf, and now I don't see the error "getnameinfo failed" again. :) But there are still many logs...
Deal all, There are so many logs in my /etc/log/message related to DNS localhost named[19893]: client 127.0.0.1#53610: query (cache)...
Separate names with a comma.
