When you open a telnet session in a script you must read the session prompts and write the replies. For example, you open a telnet session in a script and read the session and when you match the word 'Login' (or whatever) you write the user id. The same for password.

In other words, you automate in the script what you manually do at the keyboard. When you do it from the keyboard, you telnet, then wait for the login prompt. When you get the login prompt, you type the login. etc.

Writing a script is the same for telnet sessions, however instead of the keyboard, you echo (or write) in the script. Instead of seeing the login problem, you match the pattern in the script (your eyes, so to speak).

NAME

       fence_drac - fencing agent for Dell Remote Access Card

SYNOPSIS

       fence_drac [OPTION]...

DESCRIPTION

       fence_drac is an I/O Fencing agent which can be used with the Dell Remote Access Card (DRAC).  This card provides remote access to control-
       ling power to a server.	It logs into the DRAC through the telnet interface of the card.  By default, the telnet interface is not  enabled.
       To  enable  the	interface,  you  will need to use the racadm command in the racser-devel rpm available from Dell.  To enable telnet on the
       DRAC:

       [root]# racadm config -g cfgSerial -o cfgSerialTelnetEnable 1

       [root]# racadm racreset

       fence_drac accepts options on the command line as well as from stdin.  Fenced sends parameters through  stdin  when  it	execs  the  agent.
       fence_drac can be run by itself with command line options.  This is useful for testing and for turning outlets on or off from scripts.
