ruby net-ssh calling bash script with interactive prompts - ruby

Question

I have a problem that I hope you can help me with
I’m trying to use ruby to ssh onto a machine and run a bash script, this part is fairly easy but the bash script requires me to entry a username and password interactively and this is where I’m stuck
So if I run the script manually I see:-
./run_file.sh
Enter username:
Enter password:
So at the enter Username prompt I have to enter the username etc
I’ve got a simple method I use to make the connection and my idea was to pass in an array made up of
[‘command to run’, ‘username’, ‘password’]
but I don’t know how to extend the Net::SSH call to respond to the prompts
# ssh conectivity method
def command_ssh(host, cmd)
require 'net/ssh'
user = LocalConfig::SSH_DETAILS[:user]
pass = LocalConfig::SSH_DETAILS[:pass]
Net::SSH.start(host, user, :password => pass, :paranoid => false, :auth_methods => ['password'], :timeout => 10 )do |ssh |
output = (ssh.exec!(cmd[0]))
return output
end
end
anyone got any ideas

Answer 1

managed to fix this by using the channel function, here's the method I use now
def connect(host,command)
require 'rubygems'
require 'net/ssh'
user = LocalConfig::SSH_DETAILS[:user]
pass = LocalConfig::SSH_DETAILS[:pass
o = ""
Net::SSH.start(host, user, :password => pass, :paranoid => false, :auth_methods => ['password'], :timeout => 30 )do |ssh |
channel = ssh.open_channel do |ch|
ch.exec(command) do |ch2, success|
ch2.send_data "myUserName\n"
ch2.send_data "mPassWord\n"
ch.on_data do |ch2, data|
o += data
end
end
end
channel.wait
return o.to_s
end
end
