nfs-utils-1.0.6 is available at
   http://www.{countrycode}.kernel.org/pub/linux/utils/nfs/
and
   http://download.sourceforge.net/nfs/

It contains a few minor improvements over 1.0.5 including some that are needed
for correct functioning with 2.6.0 based kernels.

It also corrects a bug which can cause mountd to crash in the event of an
incorrect DNS configuration of a client.  This could be used in a remote 
denial of service attack in the unwise situation that an NFS server was not
firewalled from the open internet.
