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

[Daniel Holbach]

To me it looks like this should be discussed in a broader forum. If we
should deviate from Debian on this one we need to dedicate more
attention to it than "just have somebody upload it". :)

Was this discussed in some Debian bug report or mailing list already?
Can this be brought up on ubuntu-devel-discuss at lists.u.c maybe, so we
can find out who would be interested in maintaining this delta or find
another way to resolve the issue of old applications still using
gethostbyaddr*.

For now I'll unsubscribe the sponsors team as more discussion needs to
happen before this can be uploaded.

Title:
  nscd doesn't cache host entries

Status in “eglibc” package in Ubuntu:
  Triaged

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?
