Is there a way to read a file over SSH? I looked at the net/ssh library
but couldn't put together a working code.

Thanks.

You're probably interested in Net::SCP:

Here's a wild guess - does it help?

require 'net/ssh'
require 'net/sftp'

Net::SSH.start( 'myserver', 'myname', 'mypassword' ) do |session|
session.sftp.connect do |sftp|
sftp.get_file('path/filename', 'filename')
end
end

Thanks for your replies. I'll look into SCP and try using SFTP. :)

Just FYI:

The terms are regularly used interchangeably, but it's "SFTP" what you
will use. "SCP" is the original file transfer protocol over ssh, but it
is not in use anymore unless you have a really really old server you are
connecting to. "SFTP" is the new protocol that in use on modern ssh
servers.

Yeah, that's probably correct. There are scp and sftp commands for
linux, but they should both use the sftp protocol (there are just usage
differences between the two programs). Ruby's scp and sftp methods may
be different though.

It's all very confusing, I know.
