Installation Guide

The preferred way to install RadSSH is to use Python’s pip <> utility. If you do not have administration (root) privileges to install Python packages into the system level directories, pip can install RadSSH to a virtual environment <>.

Pip will handle the appropriate installation of RadSSH for your Python environment, either system-wide or virtual environment, and also utilitze the Python Package Index to install any missing dependencies. RadSSH currently requires Paramiko <> and netaddr <> packages, and pip will download these (and their dependencies) and install them if they are not already installed.

Installing from PyPI

If you are installing to a virtual environment, be sure to activate the environment prior to running pip.

Run the command (with sudo, if needed): pip install radssh

This should download and install RadSSH from the internet, along with the dependency packages (as well as their own dependencies, etc.)

Installing from GitHub, with pip

Run the command (with sudo, if needed): pip install git+

As with installation from PyPI, this will download and install (from source on GitHub) the latest version of RadSSH, along with its dependencies.

Installing from Developer Source

If you have a local source tree, either from a developer checkout or from un-tarred source package, you can install RadSSH in a similar fashion, replacing the URL of the repository with the local directory. Alternatively, you can cd into the source directory and run pip install .

Verifying the Install

Once installed, you should run python -m radssh (or if running Python 2.6, python -m radssh.__main__) as a diagnostic test. If successful, it will report the results of loading the RadSSH package and its dependencies, along with some details about the Python runtime environment and current host. It will also run some capacity checks for the system limitations on concurrent open files and execution threads. These upper limits, if listed, are a significant factor in how many concurrent connections RadSSH will be able to handle on your system.
