I got a new DSL connection last week, and right now I have a flat rate

That's the problem:
NIS is configured and tries to connect to the NIS server on localhost.
It uses portmap to locate the server, but portmap is not running.
2.2 just forwarded the error message to the application, but 2.4
silently ignores the error message because these error messages caused
spurious application faults.
Check your nis configuration (afaik /etc/nsswitch.conf)

Ok!
I've removed all nis reference in /etc/nsswitch.conf and now there are no
more hangs...I have to admit, learning that thew execution process of tar
is somehow related to nis,portmap is a little weird :) (but that's part of
the fun isn't it?).
Thanks again for the help
Bye
P.S.
Does anyone think that this kind of problem must be documentated in
the kernel documentation?
