Doing more with SSH

SSH is an incredible Swiss-army chainsaw of secure networking. This talk presents a brief overview of how the SSH protocol works, including recommendations on how to configure SSH clients and servers for higher security. This incorporates a brief tutorial on how to create and use ssh keys for authentication, including the use of ssh-agent and agent forwarding so that password-protected keys can be used relatively painlessly. An overview of SSH's network tunneling features will be presented, including the use of static and dynamic port forwarding, jump hosts using a ProxyCommand, and light-weight VPNs with the ssh Tunnel feature. Discussion will also cover tools that can extend SSH's power like mosh (for interactive terminals on high-latency networks), sshuttle (a VPN when Tunnel won't work), and advanced-ssh-config (for simplifying the generation of complex .ssh/config files).
