54 Configuring CMC to Use Command Line Consoles

Using SSH With the CMC

SSH is a command line session that includes the same capabilities as a Telnet

session, but with session negotiation and encryption to improve security. The

CMC supports SSH version 2 with password authentication. SSH is enabled

on the CMC by default.

NOTE: The CMC does not support SSH version 1.

When an error occurs during the login procedure, the SSH client issues an

error message. The message text is dependent on the client and is not

controlled by the CMC.

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

Windows. Running

OpenSSH at the Windows command prompt does not provide

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

For Linux, run SSH Client Services to connect to CMC with any shell.

Four simultaneous SSH sessions are supported at any given time. The session

timeout is controlled by the cfgSsnMgtSshIdleTimeout property (see

"RACADM Subcommands" on page 263) or from the Services Management

page in the Web interface (see "Configuring Services" on page 129).

Enabling SSH on the CMC

SSH is enabled by default. If SSH is disabled, then you can enable it using

any other supported interface.

For instructions on enabling SSH connections on the CMC using RACADM,

see "config" on page 268 and "cfgSerial" on page 335. For instructions on

enabling SSH connections on the CMC using the Web interface, see

"Configuring Services" on page 129.

Changing the SSH Port

To change the SSH port, use the following command:

racadm config -g cfgRacTuning -o cfgRacTuneSshPort

For more information about cfgSerialSshEnable and

cfgRacTuneSshPort properties, see "CMC Property Database Group and

Object Definitions" on page 323.
