Using the Secure Shell (SSH)

It is mission critical for devices and device management to be secure. Connected embedded devices are at the core of many business processes. If their security is compromised, your customer's business may be at high risk and it also places new security demands on command line interface (CLI) device management software. Secure Shell (SSH) is a command line session that has the same capabilities as a telnet session, but with higher security. The DRAC 4 supports SSH version 2 with password authentication. SSH is enabled on the DRAC 4 when you install or update your DRAC 4 firmware.

NOTE: SSH is not available for the first fifteen minutes of operation after installing/updating the DRAC 4 firmware. During this time the host keys are generated internally. No intervention is required for the host key generation. If this operation is interrupted for any reason, key generation will start over the next time the DRAC 4 starts up.

You can use either PuTTY or OpenSSH on the management station to connect to the managed system’s DRAC 4.

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 one SSH session is supported at any given time. The session time-out is controlled with the cfgSsnMgtSshIdleTimeout object as described in the "DRAC 4 Property Database Group and Object Definitions."

You can enable the SSH on the DRAC 4 with the command:

racadm config -g cfgSerial -o cfgSerialSshEnable 1
