# 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***
* Docs: http://net-ssh.github.io/net-scp
* Issues: https://github.com/net-ssh/net-scp/issues
* Codes: https://github.com/net-ssh/net-scp
* Email: net-ssh@solutious.com
*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:
* Transfer files or entire directory trees to or from a remote host via SCP
* Can preserve file attributes across transfers
* Can download files in-memory, or direct-to-disk
* Support for SCP URI's, and OpenURI
## SYNOPSIS:
In a nutshell:
```ruby
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:
* Net::SSH 2
If you wish to run the tests, you'll also need:
* Echoe (for Rakefile use)
* Mocha (for tests)
## INSTALL:
* ```gem install net-scp (might need sudo privileges)```
However, in order to be sure the code you're installing hasn't been tampered
with, it's recommended that you verify the
[signature](http://docs.seattlerb.org/rubygems/Gem/Security.html). To do this,
you need to add my public key as a trusted certificate (you only need to do
this once):
```sh
# 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):
* tar xzf net-scp-*.tgz
* cd net-scp-*
* ruby setup.rb config
* ruby setup.rb install (might need sudo privileges)
