Well, ish...

Seeing /etc/passwd is like doing a "net users" command, in that you can see
some limited stuff about the users who can log into this box. Fortunately,
the file you want to keep secret on a Linux box (/etc/shadow), you don't
need to worry about with SSHWindows and CopSSH, as it uses NT
Authentication.

Jon

Yeah, I already got some replies from the mentioned list, I tried them
out.
Didn't work. For now I think I'll skip ssh on windows and just go with the
easier-to-setup shhd on a Fedora Core-webserver I have running at home.
Seems
a lot easier... Can't believe MS hasn't done anything about this for IIS
over
the years. 8-/

Will look into CopSSH later. Seems like the technique using this is
similar to
"ssh for windows" with the addition of some scripts and stuff
out-of-the-box.
Promising, but we'll see.

Thx for the hint though. 8-)

PS. From what I've seen with sshd on linux, the "normal" users can
traverse
directories there as well, except they can't view/edit sensitive files
like
shadow and such. However I'm not sure if normal users seeing the contents
of
passwd and groups is ok. Seems a bit, well, you know, bad... DS.
