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 fix this issue, download hotfix 824810 from support.microsoft.com. You can also see the Microsoft

Knowledge Base article 824810 for more information.

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 Configuring 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 Configure 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 configure SSH, see Configuring Services.
