High Performance Computing and Filesystems Michigan!/Usr/Group 2025-08-15 | This month, Sharan Kalwani talked about his own direct experiences in High Performance Computing (used to be called Supercomputing in the days of yore).We produce and consume an awful lot of data (have to keep them CPUs busy!). So over the decades many techniques and implantations grew – which later became the basis for several commercial/enterprise and also foundational tech for cloud based services.He would like to share the history of high speed file systems and do a quick review of present day storage.

Wireguard and VPN April 11th 2023 - MUG Meeting Michigan!/Usr/Group 2023-04-16 | Support this and our other Michigan!/usr/group videos and meetings. Learn more at http://mug.org/membershipWires, Guards, and Netflix In the tech world, VPNs are nothing new. With Netflix talking about locking down on account sharing, folks who might otherwise not know WiFi from Ethernet are trying to figure out how their college students can still use Netflix from their dorm rooms. VPNs have historically been either terribly insecure (PPTP is a pretty ugly CHAP, for instance), or incredibly challenging to set up (port forward much, L2TP/IPSec?!?). Wireguard changes that. In fact, Wireguard is so simple, it's basically like setting up an SSH connection, but with real layer 2 networking. Yes, it's sorta possible to set up a VPN with SSH (or sshuttle), but it's not really a VPN, and it's not really easy. If you add tailscale, Wireguard makes VPN pretty easy to set up -- but what's great is that complexity aside, Wireguard is also a rock solid, low overhead, highly performant VPN. And that is what I'll demonstrate. :)Shawn Powers has been a Linux sysadmin for several decades, but is best known for his time as a contributing editor at Linux Journal.

With the growing complexity of cloud infrastructure, it's becoming increasingly important to make sure that we ensure that developers can remain productive while also making sure that a misconfigured firewall rule doesn't put your organization at risk. Enter governance-as-code, the concept that allows you to declaratively state the security posture of your cloud infrastructure, and then have that live along side all your other code. In this talk I will go over how to get started with Cloud Custodian: cloudcustdian.io, an OSS tool that you can use to make sure your instances are well managed by giving your developers the freedom to use the cloud while providing them confidence to know that they won't accidentally deploy something bad on the internet.

Learn more at http://mug.orgCatch up with macOS, iOS, and more.The recent descendants of the original Macintosh computers, have been surrounded and invaded by a wide variety of new computing platforms. All of these devices run custom tailored implementations of operating system technologies that have contributed significantly to their widespread adoption in both highly specialized and massively common use cases. Through this family of platforms Apple has (ostensibly) provided increased utility and convenience while pushing the expectations of consumer privacy and security forward significantly. Apple Inc. is an American multinational company that is continuing a long campaign of profit and growth powered by these platforms,strict policies, and strategic marketing which have impacts felt around the world and in our homes.Let's take a look at some of the recent changes you might have missed as well as new changes coming down the pipeline. We'll also briefly discuss the wider competitive market for these platforms and services available today as well as consider the possibilities for computing tomorrow.Justin Triplett is a MUG Board member, senior software engineer, and consultant.

SSH Tunnels Michigan!/Usr/Group 2021-08-11 | SSH Tunnels and MoreSSH is the go to tool for sysadmins and developers for interactiveconnections to remote machines. It creates secure, encrypted connections between computers, even across hostile networks. (Unless you accept host keys without verification. DON'T DO THAT!!!).SSH can also create tunnels for encapsulating other connections, includingother TCP protocols and data. Sysadmins can bridge protocols across networks for ease of access such as a one-off data sync.Devs can present the remote 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 TCP 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 tipsfor convenience of use, including using forced command to restrict an SSH key to one purpose.Topics:Local TunnelsRemote TunnelsTunnels via 3rd-party HostsDynamic SOCKS ProxiesFoxyProxyX11 TunnelingService Tunnel ExamplesSSH Forced CommandConfiguration TipsCommand Line TipsTools That Use SSHSSH Home GameHans is chairman of the Phoenix Linux User Group (PLUG), chair for SeaGL Finance committee, founder of SeaGL Career Expo, BoF organizer for the Southern California Linux Expo (SCaLE) and founder of the Free Software Stammtisch.

It will cover what has changed since his last MUG talk in 2006, and what you can expect from Wine as a user, and what you can hope for in the future. Subjects will include Valve's Proton, CodeWeavers CrossOver, and some ruminations about 15 years of Linux and the fight to run a Free Software company for an extended period of time. Jeremy White is the founder and CEO of CodeWeavers, Inc., the corporate sponsor of the open source Wine Project.
