Logging In to a Server Over a Network Port Using PuTTY

Scenarios

Use PuTTY to remotely log in to a server over a local area network (LAN) and configure and maintain the server.

Prerequisites

Conditions

• The local PC is connected to the management network port of the server through a network cable.
• PuTTY 0.68 or later has been installed.

The PuTTY of the latest version is recommended, because an earlier version may cause a failure in accessing the server.

Data

• IP address of the server
• User name and password for logging in to the server

Procedure

1. Set an IP address and a subnet mask or add route information for the PC, and ensure that the PC can properly communicate with the server.
2. On the PC command-line interface (CLI), run the following command to check whether the server is reachable:

   Ping Server IP address

3. Double-click PuTTY.exe.

   The PuTTY Configuration window is displayed, as shown in Figure 6-2.

4. Set login parameters.
   • Host Name (or IP address): Enter the IP address of the server to be logged in to. For example, 192.168.34.32.
   • Port: Retain the default value 22.
   • Connection type: Retain the default value SSH.
   • Close window on exit: Retain the default value Only on clean exit.

   Configure Host Name and Saved Sessions, and click Save. You can double-click the saved record in Saved Sessions to log in to the server next time.

5. Click Open.

   The PuTTY login window is displayed.

   If this is your first login to the server, the PuTTY Security Alert dialog box is displayed. Click Yes to proceed.

6. Enter the user name and password.

• If an incorrect user name or password is entered, you must set up a new PuTTY session.
• If the login is successful, the server host name is displayed on the left of the prompt.
