PolySSH

A multi-hop SSH connection tool.

Installation

Simply type :

$ gem install polyssh

Usage

$ polyssh [..list of ssh options and intermediate hosts...] [email protected]: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 [email protected]:7222 [email protected]

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 [email protected]:7222 -verbose [email protected] [email protected]ination
