[Bug 613662] Re: nscd doesn't cache host entries

[Benjamin Drung]

upstream rejects the bug because "no program should have use
gethostbyaddr*", but it's still a bug in every application that uses
gethostbyaddr*. How can we make sure that we don't break those apps. How
many apps in the archive are using gethostbyaddr*?

Status in “eglibc” package in Ubuntu: Fix Committed

Bug description:
Binary package hint: nscd

Debian (and by implication Ubuntu) are the only distros to disable nscd hosts caching. In most cases, it is deployed with the expectation to mitigate expensive lookups (eg over VPN).

The bug cited [1] has been rejected by the core glibc developers three years ago as not a bug; all other distros (including Redhat EL and Novell SLES) have this functionality enabled. Why should we continue to penalise Ubuntu's performance any longer, in cases where nscd is deployed to improve performance?
