Accessing the Linux system via SSH in Windows (redhat)

Ssh:

traditional Web services such asftp, pop, and telnet are inherently insecure because they transmit passwords and data in plaintext on the network, and it is very easy for an ulterior motive to intercept the passwords and data. Moreover, the security authentication methods of these service programs also have their weaknesses, that is, it is very easy to be attacked by the "man in the Middle" (man-in-the-middle) way. The so-called "middleman" attack means that the "middleman" pretends to be the real server to receive the data you pass to the server, and then impersonate you to pass the data to the real server. The data transfer between the server and you is a very serious problem after the hands and feet of the "middleman". By using SSH, you can encrypt all the transmitted data so that the "man-in-the-middle" attack is not possible, and it can prevent DNS spoofing and IP spoofing. An additional benefit of using SSH is that the transmitted data is compressed so that the transfer speed can be speeded up. SSH has many functions, which can replace Telnetand provide a secure "channel" for FTP,PoP, and even PPP .

To connect a Linux system via SSH under Windows:

1. Verify that SSH is installed and booted on the Linux system:

SSH is generally installed in the Redhat system, available command:ps-ef|grep sshd View

Execute command to install SSH, command:service sshd start

2. After installing the Putty software on the Windows system download, open:

3. Enter the IP address of the Linux system in the Putty, click Open

4. Enter the user and password in the command interface to enter Linux:
