Connect to a Cisco switch with SSH and Ruby -


i'm trying connect cisco switch ssh , ruby. problem need enter empty 'login as' ask me user name , password. on putty this: putty

here how have tried connect net::ssh. 

cisco = "host" #enter ip address here  user = "operacao" #enter username here  pass = "" #enter password here  tn = net::ssh::telnet::new("host" => cisco, "timeout" => 60, "prompt" => /^\login as:/ )  tn.cmd("\n") { |c| print c }  tn.cmd("\n#{user}") { |c| print c }  tn.cmd(pass) { |c| print c }  tn.print("echo oi") { |c| print c }  tn.close

is there way ruby?

i find sample here hope gives direction. before run code certify run:
gem install net-ssh 

   #!/usr/bin/env ruby    require 'net/ssh'     host = '192.168.1.113'    user = 'username'    pass = 'password'     net::ssh.start( host, user, :password => pass ) do|ssh|    result = ssh.exec!('ls')    puts result    end

the requirement of net::ssh openssl bindings ruby, can check if ok this: 

c:\sites>ruby -ropenssl -e 'puts openssl::openssl_version' openssl 1.0.0k 5 feb 2013  c:\sites>

edit:
did research , found answers, think should take at:
telnet cisco switch ,
net-ssh configure juniper router

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
