Dell Chassis Management Controller Version 6.0 for PowerEdge M1000e User’s 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 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.
