These simple messages are friendly to the user, but make the development testers unclear about specific error messages. How do I get the Win7 to display detailed error messages? You can configure IIS7 to output verbose error messages

We have introduced the ssh remote logon protocol for linux and the ssh password-less logon method. Here, we log on to linux using secureCRT and putty in windows to see how to create, configure, and log on to linux, make a memorandum.
