by default.
7 Click Services to open the SSH and Telnet Configuration screen.
NOTE: SSH and Telnet programs both provide access on a remote machine.
8 Click Enable on either SSH or Telnet as required.
9 Click Apply .
NOTE: SSH is a recommended method due to better security and
encryption mechanisms.
NOTE: SSH/Telnet session duration can be infinite as long as the timeout
value is set to 0. The default timeout value is 1800 seconds.

Using Serial Over LAN (SOL)
This section provides several methods to initialize a Serial-Over-LAN session
including a Telnet program, an SSH client, IPMItool, and SOL Proxy.
The purpose of Serial Over LAN feature is to redirect the serial port of the
managed server through iDRAC6 into the console of your management station.
Model for Redirecting SOL Over Telnet or SSH
Telnet (port 23)/ SSH (port 22) client ←→ WAN connection ←→
iDRAC6 server
The IPMI-based SOL over SSH/Telnet implementation eliminates the need for
an additional utility because the serial to network translation happens within the
iDRAC. The SSH or Telnet console that you use should be able to interpret and
respond to the data arriving from the managed server's serial port. The serial port
usually attaches to a shell that emulates an ANSI- or VT100- terminal. The serial
console is automatically redirected to your SSH or Telnet console. The SOL
redirection can then be started from the /system/soll target.
See "Installing Telnet or SSH Clients" for more information about using
Telnet and SSH clients with iDRAC.
