Dear sunmanagers members - thanks for all the help. The problem was
again a PEBKAC-type (problem existed between keyboard and chair). 

Of course a problem like this is hard to detect remotely, but still I
found it, and your support was a big help in this. Thanks. 

The problem was, that I had a bad routing table, routing internal
addresses defaultly through the external interface... kind of
embarrassing :I - as soon as I fixed that, everything worked right
witha jumpstart installation.

Still, I got really good suggestions, ones that I haven't been aware
of, let me share: 

The solutionsuggestions were: 

Darren Dunham, Dan Stromberg and Hutin Bertrand suggested the same:

Clift, Robert suggested controlling the consistence of /etc/ethers /etc/hosts 
and /etc/bootparams.


Saxon, Stuart informed asked/suggested:

Thanks - that was wrong too. 


joe fletcher, Vladimir and Paul Greidanus suggested using jumpstart/flar utility (which 
was the endsolution):

They were right - setting up jumpstart doesn't take that long, and
though it wasn't the way I wanted to solve the problem, it was surely
the easier path. thanks.
