How to automate telent verification of multiple host from command prompts

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,
Till up to now i am using manual command to verify the connetvity of hosts using telenet by below command

[usename@servername:/tmp]telnet servername xxxx(port)
[download]

after running the above command i use to see the message as connected to server from the output console,once after that i use to type 'ctrl + ]' and telent> q to exit from the telnet session.As this methos is helpful for verifying connectivity for few host. As i need to verify it for 3000 host, it is very tedious task to do it manually for each and it is very time consuming.
Dear monks could you please help me how to automate this.

You could roll your own, but it is probably the case that Nmap::Scanner has all you need.	[reply]

Assuming your company didn't provide the actual hardware to the co-location supplier, ask the colocation supplier whether there is IPMI available on the servers, or other preferred ways to monitor proper functionality. As Occam said: Entia non sunt multiplicanda praeter necessitatem.	[reply]
