I recently downloaded net/ssh 1.0.7 and net/sftp 1.1.0. But I get  
problems with ruby 1.8.2, 1.8.3 on  
either windows, debian or ubuntu boxes.

require ‘rubygems’  
require ‘net/sftp’

sftp\_sess = Net::SFTP.start ‘host’, ‘username’, ‘password’  
sftp\_sess.put\_file ‘/home/uberriffic/test.txt’,  
‘/home/uberriffic/remote\_test.txt’  
NoMethodError: private method `open' called for #<Net::SFTP::Protocol::Driver:0xb7863790> from /usr/lib/ruby/gems/1.8/gems/net-sftp-1.1.0/lib/net/sftp/protocol/driver.rb:201:in`method\_missing’

`put\_file’

from :0

Do I need ruby 1.8.4? Thanks

Zach,

Thanks for this report. I’m not sure yet what’s going wrong here, but  
I can duplicate the error on my machine and I’ll look into it.

Here are two workarounds:

First, you can use a block to Net::SFTP.start:

Net::SFTP.start(…) do |sess|  
sess.put\_file(…)  
end

Or, if you can’t use the block format for whatever reason, be sure to  
call #connect after calling start:

sess = Net::SFTP.start(…)  
sess.connect  
sess.put\_file(…)

Not sure why that connect isn’t being called automatically, but I’ll  
look into it.

A bit off topic for this thread, but is Net::SFTP the best way to do  
things like user-uploads to a rails app to a remote host like  
Strongspace?
