How to use Net::SSH

Hi all,

I am having following code in ruby

require ''net/ssh''
 require ''net/sftp''
 begin
    Net::SSH.start
(''132.147.161.159'',:password=>''k'',:port=>1234,:username=>''k'')
do |ssh|
      ssh.sftp.connect do |sftp|
        Dir.foreach(''.'') do |file|
            puts file
        end
    end
end
rescue Exception=> Ex
puts Ex.message
end

After executing the above code it is giving me following error

Bad file descriptor - connect(2)

username, password, and ipaddress are fine

What I want is to take data from remote machine to server.

Please Help me out.


Thanks and Regards,
Shri

What are you wanting to do?  SFTP or SSH?  From the code,
it appears that you''re trying to move a file from point A to B.
Thus, here''s a brief outline of the things that you can do with
SFTP:

require ''net/sftp''

  Net::SFTP.start(''host'', ''username'',
:password => ''password'') do |sftp|
    # upload a file or directory to the remote host
    sftp.upload!("/path/to/local", "/path/to/remote")

    # download a file or directory from the remote host
    sftp.download!("/path/to/remote", "/path/to/local")

    # grab data off the remote host directly to a buffer
    data = sftp.download!("/path/to/remote")

    # open and write to a pseudo-IO for a remote file
    sftp.file.open("/path/to/remote", "w") do |f|
      f.puts "Hello, world!\n"
    end

    # open and read from a pseudo-IO for a remote file
    sftp.file.open("/path/to/remote", "r") do |f|
      puts f.gets
    end

    # create a directory
    sftp.mkdir! "/path/to/directory"

    # list the entries in a directory
    sftp.dir.foreach("/path/to/directory") do |entry|
      puts entry.longname
    end
  end

Good luck,


-Conrad

Re: How to use Net::SSH

Hi,
Thanks Conrad for ur urgent reply

What I want to do is just pickup the images from machine A to machine
B.

I did what you say but I am getting error as follows

E:/InstantRails/ruby/lib/ruby/gems/1.8/gems/net-sftp-2.0.2/lib/net/
sftp.rb:43:in
 `start'': undefined method `shutdown!'' for nil:NilClass
(NoMethodError)
        from SSHTransfer.rb:8

what I write is this
sftp=Net::SFTP.start(''132.147.161.159'',
''k'',:password => ''k'')

Thanks and Regards

Can you upgrade the gem and retrying what you
did before?  You can upgrade by doing the following:

sudo gem update

Re: How to use Net::SSH

Hi,

I updated the gem.
but still it is showing me the same error.
I am using windows, is that a problem for SFTP?
IS OpenSSH require for SFTP to connect to remote machine?
Is there any other way to do this?

Thanks and Regards,
Shripad

Shripad, I''m not sure of the state of Capistrano on Windows. 
I''m sure that
you''ll need the OpenSSH library installed on your system.  Thus, it may
be
easier to install Cygwin and install OpenSSH from there.  Otherwise, you can
switch to Linux or Mac OS X or other Unix variant.

Good luck,

Re: How to use Net::SSH

Ech we were fooled by misleading example from
http://net-ssh.rubyforge.org/sftp/v1/faq.html.
The correct API is at http://net-ssh.rubyforge.org/sftp/v2/api/index.html.
So instead of

sftp = Net::SFTP.start(''host'', ''username'', 
''password'')

it should be:

sftp = Net::SFTP.start(''host'', ''username'',
:password => ''password'')
