The code is correct it's a perldoc example. Make sure the $host variable is assigned correctly.

In windows, try this :Get into cmd

try using the default port
Code:
telnet  hostname 23

See if you can connect. And then login. If you fail, find out what port you should use. Some flavors of telnet require ports like 992 for example, not the default 23.

After it works manually, transfer that information into your code. The perldoc article shows how to set port and other options.

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.
