Using previous gems with latest ruby

Ruby

Hi,

Is it possible to use previous gems to be used with Latest Ruby 1.9.2

Actually earlier i use Ruby 1.8.7 and netssh 1.1.2 and needle 1.3.0

I upgrade to Ruby 1.9.2.

However with Ruby 1.9.2,netssh and needle gems are intergrated, plz
correct me if im wrong, but for sure syntax are changed for netssh
commands.

I have code which i use to send commands to remote linux machine, which
is used to work preciously with Ruby 1.8.7 and netssh 1.1.2.

Code is like :

def issueCommandInKazBox(okMachine="", command="", matchLog="",
user=“admin”, passwd=“kazeon”)
puts " issueCommandInKazMachine=#{okMachine}"
puts " issueCommandInKazcommand=#{command}"
puts " issueCommandInKazstatus=#{matchLog}"
puts " issueCommandInKazuser=#{user}"
puts " issueCommandInKazpasswd=#{passwd}"

tempString = “”
Net::SSH.start(okMachine, user, :password => passwd, :paranoid => false
) do |session|
#Net::SSH.start(okMachine, user, passwd) do |session|

session.open_channel do |channel|

channel.on_success do
  puts "shell was started successfully!"

  puts "Adding command - #{command}..."

  channel.send_data "#{command}\n"

  channel.send_data "exit\n" # tell the shell to exit
end
channel.on_failure do
  puts "shell could not be started!"
end

channel.on_data do |ch,data|
  puts "recieved the following from shell"
  puts "#{data}"
  tempString = tempString + "\n" + data
end

channel.on_close do
  puts "shell terminated"
end

channel.send_request "shell", nil, true

end
session.loop
end

$_ = tempString
$outputofissueCommandInKazBox = tempString
if /#{matchLog}/
puts “PASSED! issueCommandInKazBox - find match log - #{matchLog}”
return true
else
puts “FAILED! issueCommandInKazBox - could not find match log -
#{matchLog}”
return false
end

end

But now with Ruby 1.9.2 and netssh 2.1.4. This doesn;t work.

So is it possible to install ruby 1.9.2 and then netssh 1.1.2 and then
while executing scripts i can direct script to use netssh 1.1.2
installed dir command so that above code works.

Currently it throws me error like :

Maybe. Depends on the gem. See http://isitruby19.com/

But now with Ruby 1.9.2 and netssh 2.1.4. This doesn;t work.

Assuming the older gem is not 1.9.2 compatible, then no.

The better approach is to branch your code based on Ruby version
detection. Something along the line of:

if RUBY_VERSION.include?(“1.8”)

call method for 1.8

elsif RUBY_VERSION.include?(“1.9”)

call method for 1.9

end
