we also use a diskless environment and also see that problem. However, as I=
=20
posted a long time ago to this list, it only happens if the nfs-utils are=20
compiled with the '--secure-statd' confiure option.
So every time we perform a general debian (testing) -update and so when als=
o=20
the nfs-utils become updated, we see that problem. Everytime this happens, =
I=20
fetch the debian nfs-utils source and recompile them without the=20
'--secure-statd' option.

When I posted that workaround, Trond told me, that its not good, since fake=
d=20
packages can be send to the statd-daemon that way. However, for us its bett=
er=20
to have an unsecured statd running than non at all. Also, the rpc.statd=20
manpage says, that the statd can be protected by the 'tcp_wrapper library'.


Cheers,
	Bernd
