der.hans: SSH Tunnels and More
Description:
Abstract: SSH is the go to tool for sysadmins and developers for interactive connections to remote machines. It creates secure, encrypted connections between computers, even across hostile networks. Secure unless you accept keys without verification (DON'T DO THAT!!!).
SSH can also create tunnels for encapsulating other connections, including other protocols and data. Sysadmins can bridge protocols across networks for ease of access such as a one-off data sync. Devs can present the dev database on their desktop to ease use of graphical development tools.
After attending this session, audience members will be able to create a local tunnel from client to server, a remote tunnel from server to client, and do simple analysis of local vs remote evaluation of a command. Attendees will be able to use tunnels for SSH or sample other protocols (MySQL and HTTP), and tunneling via a third party system. They will also be familiar with dynamic SOCKS proxies and using SSH to tunnel graphical applications. Finally, attendees will also learn SSH configuration and command line tips for convenience of use, including using forced command to restrict an SSH key to one purpose.

Sriram Ramkrishna: Circular Datacenter - Natural partners for FLOSS and Open Hardware
The Circular Datacenter is the idea that we can reuse datacenter
components and recertify them to new markets. This talk describes the
supply chain that the circular datacenter creates, and how we can leverage
that to build sustainable computational power that naturally allies itself
to free and open source software and open hardware.
About Sriram:
Sri is a 20+ veteran of free and open source both professionally and as a labour of love. In open source he works across the board with professional organizations, non-profits, and of course open source projects.
Sri currently works for ITRenew - a company in the circular data center space, as a Principal Ecosystems Engineer. In that role, Sri works with open source communities and organizations building rapport and finding ways to contribute to the upstreams that his employer depends on.
