Using Net::SSH gem to kill a process in a remote server. Partial answer to SO question #11832211

net_ssh_kill_process.rb

If you want to use the net/ssh gem to kill the process:

    require 'net/ssh'

    Net::SSH.start('host', 'user', :password => "password") do |ssh|
      ssh.exec "ps -ax | grep ruby" do |ch, success|
        ch.on_data do |c, data|
          # Too lazy to write the entire code
          # The "data" object has the output that gets printed out to stdout
          # when the command `ps -ax | grep ruby` gets executed.
          # So you need to split the lines..something like data.split("\n")
          # That gives you an array of all processes that are running ruby

          # Get the process id into :process_id by regex of somesort and kill it by
          c.exec "kill -9 :process_id" # using c here. Need to check this if `c` can be used.
        end
      end
