Hi everybody,
I want to start and interact with a process on another machine.
After reading example 20.10 in "The Ruby Cookbook" and doing some internet
research I decided to use net/ssh and popen3.
Sadly, it does not work - it just doesn't do anything noticeable, it
doesn't even terminate.
Here's my code:
----------- CODE ----------------
require 'rubygems'
require 'net/ssh'
def run_remotely(command)
Net::SSH.start("localhost", "tester", :password => "pass") do |session|
session.process.popen3(command) do |stdin, stdout, stderr|
yield stdin, stdout, stderr
end
end
end
run_remotely('cat') do |stdin, stdout, stderr|
stdin.puts 'Line one.\n'
end
----------- /CODE ----------------
Why doesn't this work?
Thanks,
Philip
P.s.:
I have successfully used channel.exec to execute "ls", but it doesn't seem
like it allows two-way communication.
