To enable the SSH or Telnet, run the command:
• Telnet:
– Using config command: racadm config -g cfgSerial -o cfgSerialTelnetEnable 1
– Using set command: racadm set iDRAC.Telnet.Enable 1
• SSH:
– Using config command:racadm config -g cfgSerial -o cfgSerialSshEnable 1
– Using set command: racadm set iDRAC.SSH.Enable 1
To change the SSH port:
– Using config command:racadm config -g cfgRacTuning -o cfgRacTuneSshPort <port

IPMItool <−−> LAN/WAN connection <−−> iDRAC7
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 iDRAC7 must be encrypted using the encryption Key (Key Generator (KG)Key). You can
configure the encryption key using the iDRAC7 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
For installation instructions, see the
2. At the command prompt (Windows or Linux), run the command to start SOL from iDRAC7: ipmitool -H
<iDRAC7-ip-address> -I lanplus -U <login name> -P <login password> sol
activate
This connects the management station to the managed system's serial port.
3. To quit a SOL session from IPMItool, press <~> and <.> one after the other. The SOL session closes.
