I apologize if this is not the right place to post a message about a gem  
like Net::SFTP - if there is a more appropriate forum please let me  
know.

When I try to connect to one SFTP server, everything works great. This  
is the code:

require “net/sftp”

class TestSftp  
Net::SFTP.start("", “”,  
:password =\> “”)  
do |sftp|  
sftp.download!("",  
“”)  
end  
end

However when trying to connect to a particular SFTP server, I receive  
the following error message:

/var/lib/gems/1.8/gems/net-sftp-2.0.2/lib/net/sftp/operations/download.rb:307:in  
`on_open': open 0014059_PRICE.CSV: failure (4) (RuntimeError) from /usr/lib/ruby/1.8/rubygems/custom_require.rb:27:in`to\_proc’

from testSftp.rb:12

Line 307 in download.rb looks like this:

raise “open #{entry.remote}: #{response}” unless response.ok?

However, I really don’t know what’s going on. One thing to note is that  
I can sftp fine from the command line to this particular server - I’m  
pretty sure it’s not an issue with my login credentials being correct.  
I’m wondering if a different protocol is being used and Net::SFTP is  
having problems with that. Does anyone have any experience with this?  
Thanks.

I did not mean to post this multiple times - I thought I was seeing a  
“Preview” screen and backed up to make minor edits and unwittingly  
re-submitted.

I am very sorry for the extra posts/noise.
