Description David Woodhouse 1999-10-07 16:25:24 UTC
When using FTP sites such as ftp.uk.kernel.org, at least one
of which is usually down, the round robin DNS entries ensure
that a second connection attempt will usually go to a
different server than the previous attempt.

However, when nscd is running, it caches the first IP
address which is returned, and doesn't ever give any of the
others. So Sod's Law dictates that I get the broken one, and
have to enter IP addresses by hand if I want any others.

nscd ought to detect the presence of multiple A records
somehow, and either download them all or just refuse to
cache them.
