hiyah Joshua,

I think I can help you with 1) and 2)...

	1) How do I get X forwarding to work? 

X forwarding should work just fine for me (both from and to windows),
setting the display and enabling all hosts on the server is all i've done
and it works. but I don't think you will be able to build xemacs with x
support on windows; at least you cant do that with gnu emacs IIRC. at any
rate try the xfree-cygwin mailing list.

	2) Is there a way to rlogin or ssh into the Win2K box? 

	make a search on the mailinglist on how to start the ssh daemon. it
works fine, we have it here at the office. 

	all&all, make a search on the archives; i found that 90% of the my
questions have been asked before...

	hope it helps.

	marco

  Unless one wants an ancient version compiled for cygwin B20.1,  you are
correct.

huh people, maybe i'm really confused here... but i think Joshua wants a
build of xemacs
that allows him to redirect the display to another xserver. am i wrong in
saying that, if at all possible, you need to build it yourself to get it to
compile using cygwin's xfree libs?

That's a usual corollary of a single developer creating something.

Correct. This was stated in the development list: the source for
cygserver was only merged in post 1.3.10 being released, so no release
of cygwin has occurred with the cygserver built.

I already answered this.

Yes.

Use cygrunsrv if you want this to happen.

Ah, that sort of privilege. Well as it isn't slated to perform user
context changes, that hasn't come up. It certainly could if it ran as a
user with the appropriate access, and the appropriate additional code
was added.

Review the _execve code. Create a cygserver message class for use in
that code, and use cygserver to create processes when the set[u|g]id bit
is set. Once the process is created cygserver should return the handle
that CreateProcess returns, and then the _execve code continues as
normal.

Too low level - we don't directly map in the image ourself - we use
CreateProcess.


...
cygrunsrv doco - you should just reference the cygrunsrv man page IMO -
rather than recapitulating it in the cygserver doco.

No. The answer is no. Any cygwin process can attach to the server. It
uses standard NT calls to identify the uid and gid of the process. 
  

Good work on the collation to date, keep it coming :}.
