ssh-python 0.3.0

Wrapper for libssh C library.

Bindings for libssh C library.

Installation

Currently only installation from source is provided. Binary wheels to follow.

To install from source, run the following:

pip install ssh-python

Project is beta status.

Prerequisites

• OpenSSL or gcrypt library and development headers

• Optionally Zlib library and development headers for compression

Libssh source code is embedded in this project and will be built when installation is triggered per above instructions. Versions of libssh other than the one embedded in this project are not supported.

Quick Start

from __future__ import print_function

import os
import pwd

from ssh.session import Session
from ssh import options

USERNAME = pwd.getpwuid(os.geteuid()).pw_name
HOST = 'localhost'

s = Session()
s.options_set(options.HOST, HOST)
s.connect()

# Authenticate with agent
s.userauth_agent(USERNAME)

chan = s.channel_new()
chan.open_session()
chan.request_exec('echo me')
size, data = chan.read()
while size > 0:
    print(data.strip())
    size, data = chan.read()
chan.close()

Output:

me

Features

The library uses Cython based native code extensions as wrappers to libssh.

• Thread safe - GIL is released as much as possible

• Very low overhead thin wrapper

• Object oriented - memory freed automatically and safely as objects are garbage collected by Python

• Use Python semantics where applicable, such as context manager and iterator support for opening and reading from channels and SFTP file handles

• Raise errors as Python exceptions
