Instructions will be posted on the above website and sent to our mailing lists when available. * ONLINE Sessions * NO PHYSICAL MEETINGS until further notice. * ONLINE session will use remote video software on 10 June 2020. What! BASE: *Activating Linux on a Chromebook* by Don Ellis ...which is way different and easier than it used to be. This tutorial might show factors common with both personal and enterprise computing. MAIN: *DNS Wars* by David Forrest The MAIN presentation is "DNS security improvements" or "DNS Wars" DNS=Domain Name Service. This allows your computer to ask distant "authoritative" servers to translate the written name of a site (ex. sluug.org") into an IP address. Traditional DNS traffic is unencrypted, meaning that, even if you think you've encrypted the CONTENT of your communication, anyone can easily get a list of what sites you visit by name. Encrypting the DNS traffic, as well as other improvements is what WILL happen in 2020. The DNS resolution process has been abused for surveillance, advertising insertion, and exfiltration. It has even been used to sneak Bitcoin/crypto-currency mining JavaScript onto the user's system. The DNS resolution process is soon to be under forced revision. Topics included will be: * EDNS Extended DNS, * IRTS Working Group studying Resolverless DNS. * EP protections, * DNSsec signatures, * DNSmasq, * I18N international non-latin character sets. Also discussed will be the Cloudflare service which will block malicious content (AND OPTIONALLY adult-content).
