Configuring CMC to Use Command Line Consoles 51

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

Firmware Version 2.0 Administrator Reference Guide) or from the Services

Management page in the Web interface (see "Configuring Services" on

page 139).

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 Firmware Version 2.0

Administrator Reference Guide. For instructions on enabling SSH connections

on the CMC using the Web interface, see "Configuring Services" on

page 139.

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 Firmware Version 2.0 Administrator

Reference Guide.

The CMC SSH implementation supports multiple cryptography schemes, as

shown in Table 3-2.
