PolySSH

A multi-hop SSH connection tool.

Simply type :

$ gem install polyssh

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

You can use as many intermediate hosts as you need.

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

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
