Command Description
NOTE: You can also use the racadm connect command.
exit, logout, and quit All the commands perform the same action. They end the current session and return to a
login prompt.
Using Telnet Console With CMC
You can have up to four Telnet sessions with CMC at a time.
If your management station is running Microsoft Windows XP or Windows 2003, you may experience an issue with the characters in a
CMC Telnet session. This issue may occur as a frozen login where the return key does not respond and the password prompt does not
appear.
To x this issue, download hotx 824810 from support.microsoft.com. You can also see the Microsoft Knowledge Base article 824810 for
more information.
In the command line interface, you can manage session timeouts using the racadm command, racadm getconfig -g
cfgSessionManagement. For more information, see the Chassis Management Controller for Dell PowerEdge M1000e RACADM
Command Line Reference Guide.
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. The CMC supports SSH version 2 with password authentication. SSH is enabled on the CMC by default.
NOTE
: CMC does not support SSH version 1.
When an error occurs during the CMC login, 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 must 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 systems running Linux, run SSH client services to connect to CMC with any shell.
Four simultaneous SSH sessions are supported at a time. The session timeout is controlled by the cfgSsnMgtSshIdleTimeout
property. For more information, see the database property chapter of the Chassis Management Controller for Dell PowerEdge M1000e
RACADM Command Line Reference Guide, the Services Management page in the Web interface, or see Conguring Services.
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 Congure Public Key Authentication over SSH.
SSH is enabled by default. If SSH is disabled, then you can enable it using any other supported interface.
To congure SSH, see Conguring Services.
