Problem with Net::SFTP

[Robin Walker]

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("<hostname>", "<username>",
assword => "<password>")
do |sftp|
sftp.download!("<remotefile>",
"<localfile>")
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

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.
