Is Putty only good for SSH or I can use it for anything else?Putty is just a simple yet powerful telnet, SSH, and Rlogin client. It offers good customization options related to security, appearance, and encryption. Other Putty variants offer secure FTP over Internet, SCP or RSA key generators. All these can be obtained from the developer website.
This open source program is by far the most perfect telnet/ssh program I have ever seen. It is a super small download (only 200k!) and has a whole slew of options you can tweak. The window resizes properly just by dragging the lower right corner, unlike many other win telnet programs. It has simplistic and intuitive user interface, and I see absolutely no reason why you would buy some crappy shareware telnet program when you could get this for free. My only disappointment is no install program, but it's easy just to throw this exe somewhere and make a shortcut on the desktop.
