76 Configuring and Using the DRAC 5 Command Line Console

Configuring the Telnet Port Number

Type the following command to change the telnet port number on the DRAC 5.

racadm config -g cfgRacTuning -o cfgRacTuneTelnetPort

Using the Secure Shell (SSH)

It is critical that your system’s devices and device management is secure.

Embedded connected devices are the core of many business processes. If

these devices are compromised, the customer’s business may be at risk, which

requires new security demands for command line interface (CLI) device

management software.

Secure Shell (SSH) is a command line session that includes the same

capabilities as a telnet session, but with improved security. The DRAC 5

supports SSH version 2 with password authentication. SSH is enabled on the

DRAC 5 when you install or update your DRAC 5 firmware.

You can use either PuTTY or OpenSSH on the management station to

connect to the managed system’s DRAC 5. When an error occurs during the

text is dependent on the client and is not controlled by the DRAC 5.

NOTE: OpenSSH should be run from a VT100 or ANSI terminal emulator on

Windows. Running OpenSSH at the Windows command prompt does not result in

full functionality (that is, some keys do not respond and no graphics are displayed).

Only four SSH sessions are supported at any given time. The session time-out

is controlled by the cfgSsnMgtSshIdleTimeout property as described in

the "DRAC 5 Property Database Group and Object Definitions" on page 293.

You can enable the SSH on the DRAC 5 with the command:

racadm config -g cfgSerial -o cfgSerialSshEnable 1

You can change the SSH port with the command:

racadm config -g cfgRacTuning -o cfgRacTuneSshPort

For more information on cfgSerialSshEnable and

cfgRacTuneSshPort properties, see "DRAC 5 Property Database Group

and Object Definitions" on page 293.
