Thanks indeed for that link.

but it has the following line

Code:
# Assume $remote_server, $my_user_id, $my_password, and $my_command were read in earlier 
  # in the script.  # Open a telnet session to a remote server, and wait for a username prompt.
  spawn telnet $remote_server
  expect "username:"  # Send the username, and then wait for a password prompt.
  send "$my_user_id\r"
  expect "password:"  # Send the password, and then wait for a shell prompt.
  send "$my_password\r"
  expect "%"  # Send the prebuilt command, and then wait for another shell prompt.
  send "$my_command\r"
  expect "%"  # Capture the results of the command into a variable. This can be displayed, or written to disk.
  set results $expect_out(buffer)  # Exit the telnet session, and wait for a special end-of-file character.
  send "exit\r"
  expect eof

I didn't see this script working, Can you please say what needs to be done to make telnet interactive.
I search lot of sites through search engine but none gave exact information.

Thanks,
Shahnaz

fence_rsa

FENCE_AGENT(8)						      System Manager's Manual						    FENCE_AGENT(8)

NAME

       fence_rsa - Fence agent for IBM RSA

DESCRIPTION

       fence_rsa  is an I/O Fencing agent which can be used with the IBM RSA II management interface. It logs into an RSA II device via telnet and
       reboots the associated machine. Lengthy telnet connections to the RSA II device should be avoided while a GFS cluster  is  running  because
       the connection will block any necessary fencing actions.

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

       Vendor URL: http://www.ibm.com
