Hmm, could you tell how did you try to start the server when it
sigsegv'ed. I suspect, you tried to run it with totally wrong arguments.
Could you tell the [x]inetd line etc etc etc?...

I also noticed that you're using 'cvs' w/ core file from cvs-pserver
:-).

BTW, in the attachment you may find a [hopefully] correct example (at
least it works for me:-)) how to set up an ncvs-pserver in xinetd
environment. inetd line should be constructed in similar way :-).=20

In a really near future (hopefully a day or two) I will provide a set of
tools for creating repositories, starting projects etc... In fact
there's a draft of doc (in texinfo) :-)).

And finally, Alex will fix cvs-admin-guide.texi so we'll have a proper
and much more accurate documentation :-)
