Enabling supported protocol using web interface
To enable SSH or Telnet, go to Overview → iDRAC Settings → Network → Services and select Enabled for SSH or Telnet,
respectively.
To enable IPMI, go to Overview → iDRAC Settings → Network and select Enable IPMI Over LAN. Make sure that the Encryption
Key
value is all zeroes or press the backspace key to clear and change the value to NULL characters.
Enabling supported protocol using RACADM
To enable the SSH or Telnet, use the following commands.
• 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 used to perform command line communications to iDRAC. You can parse
remote RACADM and SMCLP commands through either of these interfaces.
SSH has improved security over Telnet. iDRAC only supports SSH version 2 with password authentication, and is enabled by
default. iDRAC supports up to two SSH sessions and two Telnet sessions at a time. It is recommended to use SSH as Telnet is not a
secure protocol. You must use Telnet only if you cannot install an SSH client or if your network infrastructure is secure.
Use open-source programs such as PuTTY or OpenSSH that support SSH and Telnet network protocols on a management station
to connect to iDRAC.
