Subject: Re: help with net-ssh shell-script timing

update:  i've gotten a bit further, i can now at least get the program 
to spit out the data i need... but it does it in an infinite loop >_>

SSH.start(host, user){|ssh|
    ssh.open_channel{|channel| #get root privelages
        #configure behavior of channel
        channel.on_data{|channel, data|
                puts "#{data}"
                if data =~ /^Password:/
                   channel.send_data("#{PASSWORD}\n")
                elsif data =~ /root@/
                    channel.exec("tail /some/log/file.txt")
                    channel.on_data{"STOP LOOPING, DAMN YOU!"}
                end
        channel.on_close... (etc.)

        channel.request_pty do |ch,success|
                if success
                puts "pty successfully obtained"
                else
                puts "could not obtain pty"
                end end

        channel.exec("sudoshell"){|channel, win| #custom sudo script.
                if win
                   puts "ss command sent"
                else puts "ss command FAIL"
                end
        }
...end

if i put the 2nd command anywhere but within an on_data if clause, it 
refuses to wait for the sudoshell to finish loading, all attempts to use 
a sleep, or wait command just result in it hanging forever.

could really use any advice on this one.  thanks
