Configuring CMC to Use Command Line Consoles 53

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. Review the RACLog messages to determine the

cause of the failure.

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 the database property chapter of the Dell Chassis Management

Controller Administrator Reference Guide) or from the Services Management

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

CMC also supports the Public Key Authentication (PKA) over SSH.

This authentication method improves SSH scripting automation by removing

the need to embed or prompt for user ID/password. For more information,

see "Using RACADM to Configure Public Key Authentication over SSH."

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 the config command section and the cfgSerial database property section

in the Dell Chassis Management Controller Administrator Reference Guide.

For instructions on enabling SSH connections on the CMC using the Web

interface, see "Configuring Services."

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 the database property chapter of the

Dell Chassis Management Controller Administrator Reference Guide.
