Configuring CMC to Use Command Line Consoles 63
Using SSH With 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.
CMC supports SSH version 2 with password authentication. SSH is enabled
on CMC by default.
NOTE: 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 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 197.
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 95.
Enabling SSH on 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 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 CMC using the Web interface,
see "Configuring Services" on page 197.
