Installation


Binary wheel packages are provided for Linux, OSX and Windows, all Python versions. Wheel packages have no dependencies.

pip may need to be updated to be able to install binary wheel packages - pip install -U pip.

.. code-block:: shell

pip install ssh2-python

For from source installation instructions, including building against system provided libssh2, see documentation <https://ssh2-python.readthedocs.io/en/latest/installation.html#installation-from-source>_.

Who Should Use This


Most developers will want to use the high level clients <https://parallel-ssh.readthedocs.io/en/latest/quickstart.html#single-host-client>_ in parallel-ssh <https://github.com/ParallelSSH/parallel-ssh>_ based on this library.

This library provides bindings to the low-level libssh2 C-API. It is not high level, nor easy to use. A lot of code would need to be written to use this library that is already provided by parallel-ssh.

Use parallel-ssh <https://github.com/ParallelSSH/parallel-ssh>_ unless really sure using a C-API is what is wanted.

API Feature Set


At this time all of the libssh2_ API has been implemented up to the libssh2 version in the repository. Please report any missing implementation.

Complete example scripts for various operations can be found in the examples directory_.

In addition, as ssh2-python is a thin wrapper of libssh2 with Python semantics, its code examples <https://libssh2.org/examples/>_ can be ported straight over to Python with only minimal changes.

Examples


See examples directory <https://github.com/ParallelSSH/ssh2-python/tree/master/examples>_ for complete examples.

Again, most developers will want to use parallel-ssh <https://github.com/ParallelSSH/parallel-ssh>_ rather than this library directly.

Comparison with other Python SSH libraries
