Cygwin, Unix environment for windows

Cygwin is a UNIX environment, developed by Red Hat, for Windows. It consists of two parts:
A DLL (cygwin1.dll) which acts as a UNIX emulation layer providing substantial UNIX API functionality.
A collection of tools, ported from UNIX, which provide UNIX/Linux look and feel.

To download cygwin (its free) go to www.cygwin.com

To set up an xterm on windows for a linux box make sure you select to instal xfree86 and windowmaker (should install by default with xfree86).
Then copy startx to somewhere on your pc and double-click on it.
Then type
xhost +
ssh unixuser@ipaddress-of-unix-box:0
export DISPLAY=ipaddress-of-your-pc:0

Open up the screen & type 'cd c:', you will now be at your c drive and its UNIX all the way.

If bits are missing, say vi, rerun setup.exe and select the bits you want to install.
Do not select everything as it installs hundreds of meg of tools.
