Telnet Setup

After you have configured an IP address for the system, you can run Telnet from a host to access the system through its Ethernet port. To connect the Ethernet port to the network:

  1. Connect an Ethernet cable (RJ-45) to the system's 10/100Base-T (RJ-45) port on the SRP I/O module.
  2. Connect the other end of the cable to the appropriate Ethernet network for an out-of-band connection.

Before you can access the system with Telnet, you must either configure a password for Telnet access or disable the password requirement from the management console. In the following example, you disable the password.

  1. Enter the enable command.
    host1>enablehost1#

    The system is now in Privileged Exec mode.

  2. Enter the configure command.
    host1#configure terminalEnter configuration commands, one per line. End with CNTL/Z. host1(config)#

    The system is now in Global Configuration mode.

  3. Enter the line command.
    host1(config)#line vty 0 4host1(config-line)#

    The system is now in Line Configuration mode.

  4. Disable the password.
    host1(config-line)#no login

    Note: In this example, you disabled the password requirement, but you can choose to set a password instead. See JunosE System Basics Configuration Guide, Chapter 8, Passwords and Security for information on setting a password.

  5. Run Telnet from a host on the same Ethernet network as the system.
  6. Enter the IP address of the system to open the Telnet session.

    The User Exec prompt appears when the Telnet session to the system is established.

    host1>
  7. Enter the enable command.
    host1>enablehost1#

    The system is now in Privileged Exec mode.

  8. Enter the configure command.
    host1#configure terminalEnter configuration commands, one per line. End with CNTL/Z. host1(config)#

    The system is now in Global Configuration mode, from which you can configure the system. See JunosE System Basics Configuration Guide, Chapter 2, Command-Line Interface.

    Caution: Do not change the IP address for the Ethernet interface that you are using to communicate with the system. If you change the address, you will lose the Telnet session.
