How to login in linux server

To log in to Linux server, the Windows user should enter to a program called putty, specify the appropriate host name and port number (Figure a), and press OK. Then, once the Linux window appears, he/she should enter his/her username and password on the Linux server (Figure b). After logging in is successful, the user can execute many commands against the Linux server.
