Hi,

Im trying to write a telnet client that will telnet to a switch in ruby.  
the code im using is:

localhost = Net::Telnet::new(“Host” =\> “10.76.151.193”,  
“Timeout” =\> 10,  
“Prompt” =\> /[#\>:]/n) { |resp| print  
"==\> "+resp }  
# pass username and password as commands not .login method  
localhost.cmd(“myUsername”) { |c| print c }  
localhost.cmd(“myPassword”) { |c| print c }  
localhost.cmd(“terminal length 0”) { |c| print c}  
@response = ‘’  
localhost.cmd(“show interfaces”) { |c| print c; @response += c }  
localhost.close

what api i need to download for running this program and where should i  
save it??  
this program is currently not running properly!

thanks in advance!

Hi Supriya A.,

I am using Ruby-186-26 an older stable version from what i gather I am  
super new to ruby but I was looking to do what your script did and it  
worked for me my script was a little different but yours did the trick.  
Here is the link to get the version that I am using on Windows

Ruby 1.8.6-p26 (Final) is the name. Hope this helps.
