[![Code Climate](https://codeclimate.com/github/glenux/polyssh/badges/gpa.svg)](https://codeclimate.com/github/glenux/polyssh)


A multi-hop SSH connection tool.

## Installation

Simply type :

    $ gem install polyssh

## Usage

    $ polyssh [..list of ssh options and intermediate hosts...] user@host:port

You can use as many intermediate hosts as you need.

### Example 1 : Traversing a single machine

We want to connect

* to a remote host called ``destination`` (as user ``bob``, on default port)
* via a firewall (as user ``alice``, on non-default port 7222)

The corresponding command using polyssh is :

    $ polyssh alice@firewall:7222 bob@destination

## Example 2 : traversing two machines with options

We want to connect

* to a remote host called ``destination`` (as user ``charlie``, on default port)
* via a firewall (as user ``alice``, on non-default port 7222)
* then via a router  (as user ``bob``, on default), with verbosity)

Type the following command using polyssh :

    $ polyssh alice@firewall:7222 -verbose bob@router charlie@destination
