Idiot's guide to druby using ssh tunnels

There’s nothing special about druby, you’d just tunnel it like anything
else.

-------- Server Code:

require ‘drb/drb’

class ServerObj
def initialize
@count = 0
end
def kick
@count = @count + 1
puts “I have been kicked #{@count} times”
@count
end
end

DRb.start_service(‘druby://localhost:666’, ServerObj.new)

-------- Client SSH Command:

ssh -f -L 888:localhost:666 username@servername “while echo .; do sleep
60; done” > /dev/null

-------- Client Code:

DRb.start_service

serverObj = DRbObject.new_with_uri(‘druby://localhost:888’)
10.times {
puts “Server has been kicked #{serverObj.kick} times”
}

I don’t believe there is an ssh library for ruby, otherwise you’d be
able to get a pure ruby solution.

the situation i’m in is that i’d like to write a drb app, but
ssh is the only way into any of our machines…
