Some software packages have their own cygwin repositories. All you have to do is to add their URLs during installation process.

• cygwinports.dotsrc.org. Check out the ever growing list of ports available.
• CyGNOME-2 is a GNOME 2.x port for Cygwin.
• KDE for Cygwin

Right click on the Cygwin icon on your desktop, and select "Edit". Replace the standard Windows shell with:

@echo off
C:
chdir C:\cygwin\bin
set EDITOR=vi
set VISUAL=vi
set CYGWIN=codepage:oem binmode title server
rxvt -sl -tn xterm -cr red -sr -sl 2000
		  

Note that you should have installed rxvt terminal simulator found under Shells category (I know, I know - very counterintuitive) in the installation step.

To setup ssh daemon:

• Open cygwin window and type ssh-host-config. When asked, andwer the following questions:

  "privilege separation" : yes "local user" : yes "install sshd as a service" : yes "CYGWIN" : ntsec tty server

• Start sshd server with % net start sshd. To stop the daemon, use % net stop sshd.
• Check if the daemon has started with % netstat -an. You should get something like this:

  Active Connections Proto Local Address Foreign Address State TCP 0.0.0.0:22 0.0.0.0:0 LISTENING

  Port 22 is ssh
• Try to login, to see if password file is properly setup: % ssh $USERNAME@127.0.0.1. If you can't login, the setup a cygwin password with passwd command:

  % cd /etc % cp passwd passwd.0 % passwd [enter your CURRENT Windows password here]

Cygserver runs in the backgroud as a server and provides:

• XSI IPC Message Queue
• XSI IPC Semaphores
• XSI IPC Shared Memory

First, configure the service:

% cygserver-config
		  

Now, you are ready to run the service daemon:

% cygrunsrv.exe -S cygserver
		  

Ensure that CYGWIN environment variable has "server" option enabled.
