Back to Main Page Wiki³ is run on-top of Arch Linux at OVH. The machine, as seen on the right, is from their dedicated server line and located at their Beauharnois, CA facility in datacenter BHS6. The wiki itself runs MediaWiki on-top of nginx with Let's Encrypt SSL certificates configured to achieve an A+ rating with 100 points in every category on SSL Labs. Running Arch Linux on a server in a production environment is very feasible, provided you know a bit about security and keep on top of advisories. That being said we do not live in a perfect world, and my server logs are proof of that. However since 2013 when I switched my servers over from FreeBSD to Arch Linux I have yet to have a single intrusion. History   2017-08-15 : Migration to E5v2-SAT-1-16 complete. 2017-08-13 : E5v2-SAT-1-16 setup complete: OVH: Custom Installation, Hardening Arch Linux, KVM on Arch Linux 2017-07-29 : E5v2-SAT-1-16 purchased from OVH SYS in their BHS datacenter to replace the KS-8G. 2017-07-24 : VPS-SSD1 purchased from OVH in their BHS datacenter for the creation of tutorials. 2013-12-10 : KS-8G dedicated server purchased from OVH in their BHS datacenter. 2013-05-31 : SP 16G dedicated server purchased from OVH in their BHS datacenter. Terminated 2013-01-13 : KS1 dedicated server purchased from OVH in their BHS datacenter. Terminated Network The following is the complete network setup for everything that runs kyau.net. While some things could be setup better, this setup was optimized for running everything on one large box doing in-house virtualization instead of running each on a separate VPS and letting someone else do the virtualization for me. In my experience, it can be very beneficial to have bare metal access when things go wrong. Network Overview * Denotes the IPv4 address location, all IPv6 reside in CA.

Shy of some dabbling with Slackware, which I installed from a CDROM I got in the back of a book at the local library (pre-internet joys), this was my first major introduction to Linux and the command line. I spent a good majority of my youth on IRC messing around with "shells". I even got my first major introduction to programming (aside from BASIC and HTML) when I started coding botnet scripts for eggdrop in TCL.
