remote connection to a unix machine

[Natalie Udovidchik]

my question is such.  i am trying to connect to a unix
machine remotely though cygwin.  how should i do that?
i am very new to this.

another concern is that some of the commands are not
working, such as ls, and emacs/xemacs, and others.
why could that be such?

thank you,
Natalie
