What
|
|
----
|
|
|
|
"paramiko" is a combination of the esperanto words for "paranoid" and
|
|
"friend". it's a module for python 2.6+ that implements the SSH2 protocol
|
|
for secure (encrypted and authenticated) connections to remote machines.
|
|
unlike SSL (aka TLS), SSH2 protocol does not require hierarchical
|
|
certificates signed by a powerful central authority. you may know SSH2 as
|
|
the protocol that replaced telnet and rsh for secure access to remote
|
|
shells, but the protocol also includes the ability to open arbitrary
|
|
channels to remote services across the encrypted tunnel (this is how sftp
|
|
works, for example).
|
|
|
|
it is written entirely in python (no C or platform-dependent code) and is
|
|
released under the GNU LGPL (lesser GPL).
|
|
|
|
the package and its API is fairly well documented in the "doc/" folder
|
|
that should have come with this archive.
|
|
|
|
|
|
Requirements
|
|
------------
|
|
|
|
- python 2.6 or better <http://www.python.org/>
|
|
- pycrypto 2.1 or better <https://www.dlitz.net/software/pycrypto/>
|
|
- ecdsa 0.9 or better <https://pypi.python.org/pypi/ecdsa>
|
|
|
|
If you have setuptools, you can build and install paramiko and all its
|
|
dependencies with this command (as root)::
|
|
|
|
easy_install ./
|
|
|
|
|
|
Portability
|
|
-----------
|
|
|
|
i code and test this library on Linux and MacOS X. for that reason, i'm
|
|
pretty sure that it works for all posix platforms, including MacOS. it
|
|
should also work on Windows, though i don't test it as frequently there.
|
|
if you run into Windows problems, send me a patch: portability is important
|
|
to me.
|
|
|
|
some python distributions don't include the utf-8 string encodings, for
|
|
reasons of space (misdirected as that is). if your distribution is
|
|
missing encodings, you'll see an error like this::
|
|
|
|
LookupError: no codec search functions registered: can't find encoding
|
|
|
|
this means you need to copy string encodings over from a working system.
|
|
(it probably only happens on embedded systems, not normal python
|
|
installs.) Valeriy Pogrebitskiy says the best place to look is
|
|
``.../lib/python*/encodings/__init__.py``.
|

Bugs & Support
|
|
--------------
|
|
|
|
Please file bug reports at https://github.com/paramiko/paramiko/. There is currently no mailing list but we plan to create a new one ASAP.
|
|

|
|
|
Demo
|
|
----
|
|
|
|
several demo scripts come with paramiko to demonstrate how to use it.
|
|
probably the simplest demo of all is this::
|
|
|
|
import paramiko, base64
|
|
key = paramiko.RSAKey(data=base64.decodestring('AAA...'))
|
|
client = paramiko.SSHClient()
|
|
client.get_host_keys().add('ssh.example.com', 'ssh-rsa', key)
|
|
client.connect('ssh.example.com', username='strongbad', password='thecheat')
|
|
stdin, stdout, stderr = client.exec_command('ls')
|
|
for line in stdout:
|
|
print '... ' + line.strip('\n')
|
|
client.close()
|
|
|
|
...which prints out the results of executing ``ls`` on a remote server.
|
|
(the host key 'AAA...' should of course be replaced by the actual base64
|
|
encoding of the host key. if you skip host key verification, the
|
|
connection is not secure!)
|
|
|
|
the following example scripts (in demos/) get progressively more detailed:
|
|
|
|
:demo_simple.py:
|
|
calls invoke_shell() and emulates a terminal/tty through which you can
|
|
execute commands interactively on a remote server. think of it as a
|
|
poor man's ssh command-line client.
|
|
|
|
:demo.py:
|
|
same as demo_simple.py, but allows you to authenticiate using a
|
|
private key, attempts to use an SSH-agent if present, and uses the long
|
|
form of some of the API calls.
|
|
|
|
:forward.py:
|
|
command-line script to set up port-forwarding across an ssh transport.
|
|
(requires python 2.3.)
|
|
|
|
:demo_sftp.py:
|
|
opens an sftp session and does a few simple file operations.
|
|
|
|
:demo_server.py:
|
|
an ssh server that listens on port 2200 and accepts a login for
|
|
'robey' (password 'foo'), and pretends to be a BBS. meant to be a
|
|
very simple demo of writing an ssh server.
|
|
|
|
:demo_keygen.py:
|
|
an key generator similar to openssh ssh-keygen(1) program with
|
|
paramiko keys generation and progress functions.
|
|
|
|
Use
|
|
---
|
|
|
|
the demo scripts are probably the best example of how to use this package.
|
|
there is also a lot of documentation, generated with Sphinx autodoc, in the doc/ folder.
|
|
|
|
there are also unit tests here::
|
|
|
|
$ python ./test.py
|
|
|
|
which will verify that most of the core components are working correctly.
