So then su can be implemented in Cygwin. > >>Regardless, to me it's still would be a large security hole if all one >>needs to do is: >> >>$ echo "+" > ~/.rhosts >> >>to be able to abuse rsh to do something under somebody else's user ID is >>it not? >> > > It's the same on U*X.

Also, it does not seem to matter if my home directory is locked down or not. If user A wishs to login as user B and user A can create files in his own home directory (and even if he can't since the presence of ~usera/.rhosts is not required) all user A needs to do is use rsh with a -l userb parameter to execute commands as user B. This is not the same as on Unix. > And rsh is a dangerous service anyway. If you don't want it, > just remove the matching line in /etc/inetd.conf and use ssh. Ah but I *want* rsh. I just want it to work correctly. :-) -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
