It looks like the core issue was never actually resolved: "getent hosts localhost" still doesn't return the expected result, right? $ getent hosts localhost ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 $ grep ^hosts /etc/nsswitch.conf hosts: files dns myhostname If you're not getting the expected result from "getent", and if your nsswitch.conf lists "files", then glibc is somehow broken. "rpm -V glibc" might tell you how, or it might not. Could be that glibc can't load /lib64/libnss_files.so.2. In any case, DNS is now providing you with a result for "localhost", and that'll work around most of the problems, but you really should take steps to fix glibc. With something that low-level broken, I'd urge you to build a new system from scratch, and automate the build with some configuration management tool this time, so that the next time you need to rebuild, you can do it quickly.
