Configuring CMC to Use Command Line Consoles 61
Using SSH With the CMC
SSH is a command line session that includes the same capabilities as a Telnet
session, but with session negotiation and encryption to improve security.
The CMC supports SSH version 2 with password authentication. SSH is
enabled on the CMC by default.
NOTE: The CMC does not support SSH version 1.
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. You can also run OpenSSH using Putty.exe. 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. For
more information, see the database property chapter of the RACADM
Command Line Reference Guide for iDRAC6 and CMC, the Services
Management page in the Web interface, or see "Configuring Services" on
page 195.
CMC also supports 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" on
page 93.
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 RACADM Command Line Reference Guide for iDRAC6 and CMC. For
instructions on enabling SSH connections on the CMC using the Web
interface, see "Configuring Services" on page 195.
