I’m sticking this new post under my CentOS category because it is what I’ve been using to SSH into my CentOS servers. Cygwin is a bit bulky compared to others like putty.exe, but mintty.exe has the ability to go translucent which is really cool. There’s an excellent article on installing and setting up Cygwin in Windows here by Nicholas Fong.
From time to time, I need to reference this article and it always takes me a bit of time to find this specific, well written article. To be honest, I’m a little lazy so I am reposting if from original article here to find it quicker next time around:
According to some cygwin gods, the only official document that you should use is /usr/share/doc/Cygwin/openssh.README
which is probably true.
The purpose of this tutorial is for Windows users who are perhaps less familiar with Unix commands wanting to try out the famous Open Source ssh server (openSSH) on a desktop Windows XP 
.
Please don’t send any questions to the cygwin mailing list to ask questions about this page as it seems to provoke them severely. They considered and declared the instructions on this page “broken” and “random” but won’t constructively say what is “broken”; instead some went on launching personal attacks. The information here is provided “as is, in good faith” with no guarantee it will work. If it doesn’t work, then it doesn’t work. Don’t send any questions to the Cygwin mailing list to ask why and provoke them. If you must go to Cygwin mailing list to ask, you better completely remove Cygwin before you go to the mailing list to ask questions and don’t even mention that you have looked at this web page (to avoid pissing them off).
Read this Disclaimer.
Constructive comments are of course welcome, in the original spirit of the Internet, sharing experience and knowledge regarding bug fixes and improvements to benefit other users of the Internet community.
