Using the Secure Shell (SSH)

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

Embedded connected devices are the core of many business processes.

If these devices are compromised, your 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 iDRAC6

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

iDRAC6 when you install or update your iDRAC6 firmware.

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

connect to the managed system’s iDRAC6. When an error occurs during the

text is dependent on the client and is not controlled by the iDRAC6.

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 two SSH sessions are supported at any given time. The session timeout

is controlled by the cfgSsnMgtSshIdleTimeout property as described in

the RACADM iDRAC6 and CMC Command Line Reference Guide available

on the Dell Support website at dell.com/support/manuals.

To enable the SSH on the iDRAC6, type:

racadm config -g cfgSerial -o cfgSerialSshEnable 1

To change the SSH port, type:

racadm config -g cfgRacTuning -o cfgRacTuneSshPort
