● Telnet
racadm set iDRAC.Telnet.Enable 1
● SSH
racadm set iDRAC.SSH.Enable 1
To change the SSH port
racadm set iDRAC.SSH.Port <port number>
You can use tools such as:
● IPMItool for using IPMI protocol
● Putty/OpenSSH for using SSH or Telnet protocol

SOL using IPMI protocol
The IPMI-based SOL utility and IPMItool uses RMCP+ delivered using UDP datagrams to port 623. The RMCP+ provides
improved authentication, data integrity checks, encryption, and the ability to carry multiple types of payloads while using IPMI
2.0. For more information, see http://ipmitool.sourceforge.net/manpage.html.
The RMCP+ uses an 40-character hexadecimal string (characters 0-9, a-f, and A-F) encryption key for authentication. The
default value is a string of 40 zeros.
An RMCP+ connection to iDRAC must be encrypted using the encryption Key (Key Generator (KG)Key). You can configure the
encryption key using the iDRAC Web interface or iDRAC Settings utility.
To start SOL session using IPMItool from a management station:
NOTE: If required, you can change the default SOL time-out at Overview > iDRAC Settings > Network > Services.
1. Install IPMITool from the Dell Systems Management Tools and Documentation DVD.
For installation instructions, see the Software Quick Installation Guide.
2. At the command prompt (Windows or Linux), run the following command to start SOL from iDRAC:
ipmitool -H <iDRAC-ip-address> -I lanplus -U <login name> -P <login password> sol
activate
This command connected the management station to the managed system's serial port.
3. To quit a SOL session from IPMItool, press ~ and then . (period).
NOTE: If a SOL session does not terminate, reset iDRAC and allow up to two minutes to complete booting.
SOL using SSH or Telnet protocol
Secure Shell (SSH) and Telnet are network protocols that are used to perform command-line communications to iDRAC. You
can parse remote RACADM and SMCLP commands through either of these interfaces.
To provide enhanced security, the 'keyboard interactive authentication' option has been enabled on the iDRAC SSH Server. With
this option, most SSH Clients make the user aware of this with various prompts in anticipation of potential requests from the
SSH Server. These prompts are opportunistic i.e. the SSH clients do not know if any further authentication dialog will be
requested by the server. As such when such prompts are seen their context and applicability needs to understood and ignored if
the necessary. This behavior is a characteristic of most SSH Clients that support the 'key-board interactive authentication'
option in addition to the normal 'password authentication' and 'public-key authentication'. Also, the wording of the 'dialog
prompts' will vary among the various SSH Client implementations.
