Dell IDRAC6 manual Using the Secure Shell SSH

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 login procedure, the secure shell client issues an error message. The message 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 iDRAC6 Administrator Reference Guide available on the Dell Support website at support.dell.com/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 <port number>

For more information on cfgSerialSshEnable and cfgRacTuneSshPort properties, see the iDRAC6 Administrator Reference Guide available on the Dell Support website at support.dell.com/manuals.

The iDRAC6 SSH implementation supports multiple cryptography schemes, as shown in Table 5-1.
