Chapter 2. Setting Up Console Access

This chapter discusses the following:

Serial Console Access

This section discusses the following:

Requirements for Additional Hardware

Requirements for additional hardware (not included):

  • A suitable serial cable (that is, a null modem cable) and connector type for attaching to COM1 on the back of the 1200 box (DB9 female)

  • One of the following:

    • A serial RS-232 console device

    • A workstation running terminal emulation software

    • A port on an already deployed serial concentrator or terminal server

Setting Up a Serial Console

To set up the serial console, do the following:

  1. Connect one end of your serial cable to your SGI Internet Server for Messaging on COM1.

  2. Connect the other end directly to one of the following:

    1. A console device (such as a terminal).

    2. A free port on a terminal server you have already deployed. This may be based on cat-5 cabling and RJ-45 jacks, so you may need an RJ-45 to DB9 female adapter. The combination of all these elements should produce an RS-232 null modem connection.

  3. Use your console device to gain shell access or use terminal emulator software running on a workstation (connected to your terminal server or serial concentrator equipment).


Note: By default, Linux does not allow telnet login for root. Therefore, there must be a regular user account already set up even if Bastille was not run.

For security purposes, you should deny access to the telnet daemon from all public networks, using both ipchains(8) and tcp_wrappers for redundancy. You will perform this step as part of using the Bastille Linux script. See Chapter 4, “Server Lockdown Using Bastille Linux”.

Uses for a Serial Console

Using a serial console access for preproduction tasks has the following advantages:

  • It allows you to place your server in your network operations center while still performing preproduction tasks

  • You can move your server into production mode without recabling

You will also want a remote console during production mode. In a production environment, you would typically have multiple server systems and use either a serial concentrator or a serial terminal server to access them all from a workstation in your network operations center.

Local Console Access

This section discusses the following:

Requirements for Additional Hardware

Requirements for additional hardware (not included) are one of the following:

  • Cabling and a free port on a keyboard, video, and mouse (KVM) switch already connected to an administration workstation

or:

  • Standard set of hardware:

    • A generic multisync SVGA monitor and cabling

    • A standard PC PS/2 keyboard

    • A PS/2 mouse

Setting Up a Local Console

To set up the local console, do the following:

  1. Plug the SVGA monitor into the video connector

  2. Plug the standard PC PS/2 keyboard into the keyboard connector

  3. Plug the PS/2 mouse into the mouse connector

Uses for a Local Console

You may want to use local console access while you are setting up your server before placing it in production mode, especially if you are performing preproduction tasks in an area outside your network operations center. This method is simple, but may require you to physically move and recable your system later on.
