Net::SCP

Please note: this project is in maintenance mode. It is not under active development but pull requests are very much welcome. Just be sure to include tests! – delano

As of v1.0.5, all gem releases are signed. See INSTALL.

DESCRIPTION:

Net::SCP is a pure-Ruby implementation of the SCP protocol. This operates over SSH (and requires the Net::SSH library), and allows files and directory trees to be copied to and from a remote server.

FEATURES/PROBLEMS:

SYNOPSIS:

In a nutshell:

require 'net/scp'

# upload a file to a remote server
Net::SCP.upload!("remote.host.com", "username",
  "/local/path", "/remote/path",
  :ssh => { :password => "password" })

# upload recursively
Net::SCP.upload!("remote.host", "username", "/path/to/local", "/path/to/remote",
   :ssh => { :password => "foo" }, :recursive => true)

# download a file from a remote server
Net::SCP.download!("remote.host.com", "username",
  "/remote/path", "/local/path",
  :ssh => { :password => "password" })

# download a file to an in-memory buffer
data = Net::SCP::download!("remote.host.com", "username", "/remote/path")

# use a persistent connection to transfer files
Net::SCP.start("remote.host.com", "username", :password => "password") do |scp|
  # upload a file to a remote server
  scp.upload! "/local/path", "/remote/path"

  # upload from an in-memory buffer
  scp.upload! StringIO.new("some data to upload"), "/remote/path"

  # run multiple downloads in parallel
  d1 = scp.download("/remote/path", "/local/path")
  d2 = scp.download("/remote/path2", "/local/path2")
  [d1, d2].each { |d| d.wait }
end

# You can also use open-uri to grab data via scp:
require 'uri/open-scp'
data = open("scp://user@host/path/to/file.txt").read

For more information, see Net::SCP.

REQUIREMENTS:

If you wish to run the tests, you’ll also need:

INSTALL:

However, in order to be sure the code you’re installing hasn’t been tampered with, it’s recommended that you verify the signature. To do this, you need to add my public key as a trusted certificate (you only need to do this once):

# Add the public key as a trusted certificate
# (You only need to do this once)
$ curl -O https://raw.githubusercontent.com/net-ssh/net-ssh/master/net-ssh-public_cert.pem
$ gem cert --add net-ssh-public_cert.pem

Then- when installing the gem - do so with high security:

$ gem install net-scp -P HighSecurity

If you don’t add the public key, you’ll see an error like “Couldn’t verify data signature”. If you’re still having trouble let me know and I’ll give you a hand.

Or, you can do it the hard way (without Rubygems):
