  • 18. Objectives ● ● ● Demystify FOSS (Free and Open Source Software) Have some fun with FOSS and show you how you can build nearly ANYTHING with it. In particular a home game server. FOSS Security and Networking Options (UFW/Pfsense) ● Quick overview of FOSS Virtualization choices. ● 2 Example game setups Copyright © Evolutionary IT 2008 18
  • 19. Who am I? ● ● ● Joseph Guarino Working in IT for last 15 years: Systems, Network, Security Admin, Technical Marketing, Project Management, IT Management CEO/Sr. IT consultant with my own firm Evolutionary IT ● CISSP, LPIC, MCSE, PMP ● www.evolutionaryit.com Copyright © Evolutionary IT 2008 19
  • 20. ? How many of you are familiar with or use Linux or Free and Open Source Software in some way? Copyright © Evolutionary IT 2008 20
  • 21. What is FOSS/FLOSS?     Free and Open Source Software Alternative term to describe software spectrum from free to open. FLOSS or Free/Libre/Open-Source Software. Libre is used to clarify the ambiguity of the word free in English. Copyright © Evolutionary IT 2008 21
  • 22. Dental Hygiene?
  • 23. What is FOSS? ● ● ● ● Represents a spectrum of licenses from Free to Open. FOSS (Free and Open Source Software) is a software licensing model that allows anyone the liberty to use, extend and distribute the software as they see fit. FOSS is unique as well in that it produces innovation quickly by the very concept of open, cooperative, collaborative efforts. Commercial software is much more restrictive.
  • 24. FOSS vs Commercial Software   Licensed with very specific rights associated with its use, modification, distribution and use that are not commonly available to a user via commercial “closed” software. Software licenses of traditional commercial software define specific permission, rights and restrictions.  Licensee determines the license terms.  Much more restrictive that FOSS.  Freedom, sharing, collaboration are not inherit parts of this traditional “closed” model which typifies the traditional software industry. Copyright © Evolutionary IT 2008 24
  • 25. What FOSS is NOT ● ≠ Freeware ● ≠ Shareware ● ≠ Public Domain Software ● ≠ Malware, spyware, adware, badware etc. Community standards general prohibit this. Copyright © Evolutionary IT 2008 25
  • 26. Types of FOSS The licensing spectrum.. Copyright © Evolutionary IT 2008 26
  • 27. Many FOSS Licenses ● ● ● ● There are many FOSS licenses each which allow different rights and responsibilities Most popular are GNU General Public License, GNU Lesser General Public License, BSD License, Mozilla Public License, MIT License and the Apache License. OSI Licenses – OSI Software Definition http://opensource.org/licenses/ FSF Licenses – Free Software Definition http://www.gnu.org/licenses/ Copyright © Evolutionary IT 2008 27
  • 28. OSI ● ● ● ● ● OSI – non-profit created in 1998 by Bruce Perens & Eric Raymond to promote “open source.” Open source was a repositioning of free software with a term that was to clear up the ambiguity seen in the term free. Attempt was to make free software provide a more business friendly effort. Uphold and promotes Open Source Definition. http://www.opensource.org/ Copyright © Evolutionary IT 2008 28
  • 29. Common FOSS Misperceptions.. Copyright © Evolutionary IT 2008 29
  • 30. FUD is wrong Fear, uncertainty and doubt (FUD) that FOSS is not unstable, untested, insecure software. It's quite the opposite... Copyright © Evolutionary IT 2008 30
  • 31. Few facts of note FOSS FACTS Copyright © Evolutionary IT 2008 31
  • 32. FOSS FACTS ● FOSS IS everywhere! ● Have you used that Internet? ● ● > 50% of Webservers (Netcraft), ~65-70% DNS, >50%(ISC) Email Servers ( Credentia/O'Reilly). It has been critical in the evolution of the Internet. Copyright © Evolutionary IT 2008 32
  • 33. FOSS FACTS ● ● Supercomputer – 75% of supercomputers run Linux. www.top500.org Rendering Farms – Dominates Disney/Pixar, Dreamworks, Sony, etc. ● SOHO – Linksys, Netgear, D-Link ● Mobile Phones – Android, Openmoko ● Even toys! LEGO Mindstorm NXT Copyright © Evolutionary IT 2008 33
  • 34. Who uses it? ● ● ● ● Redhat, Sun, Dell, IBM, HP, Novell, Oracle, Intel,Canonical are big players behind it. Business, government, military, educational and scientific community, i.e. NSA, FBI, CIA, NSF, NASA, Wall Street. Google, Yahoo, Adobe, Juniper. I bet its on your corporate network, at home, in your car or phone right now. Copyright © Evolutionary IT 2008 34
  • 35. Why The FOSS model works... Copyright © Evolutionary IT 2008 35
  • 36. FOSS Model works ● ● ● ● The FOSS model of cooperative, collaborative efforts yields amazing innovations but that hardly only applies to software. It has been applied in many other ways: Education – OLPC, MIT OpenCourseWare, Wikipedia, California Open Source Textbook Scientific – Boinc, Cambia, Human Genome Project, GenBank, Tropical Disease Initiative Copyright © Evolutionary IT 2008 36
  • 37. FOSS and Capitalism ● ● Some have mischaracterized FOSS as diametrically opposed to capitalism. Those suppositions show a fundamental lack of understanding of FOSS and its business model. ● FOSS thrives for many reasons. ● Business involvement is one of them. Copyright © Evolutionary IT 2008 37
  • 38. Industry Projections ● Sales of open source software will grow from $1.8bn in 2006 to $5.8bn in 2011. Matt Lawton, program director for IDC's Open Source Software Business Models research program, typified the current market as "immature" and in the "early stages". Copyright © Evolutionary IT 2008 38
  • 39. Distro/OS Options Freedom and choice are yours Copyright © Evolutionary IT 2008 39
  • 40. OS's (Linux/Unix - Commercial) ● Linux/Unix Distros - ● Redhat - www.redhat.com ● Novell - www.novell.com ● Canonical – www.canonical.com ● Sun – www.sun.com ● Commercial support ● All of these projects have a community driven effort. Copyright © Evolutionary IT 2008 40

OpenBSD has stellar security history. Project is model of success of security in the Open Source world. Only 2 remote holes in the default install in 10 years! O'Bsd brought you OpenSSH, OpenBGPD, OpenNTP and OpenCVS. Copyright © Evolutionary IT 2008 42

  • 71. Onward to the world of... VIDEO GAMES! Copyright © Evolutionary IT 2008 71
  • 72. Interesting Quote Video games are bad for you? That's what they said about rock and roll. SHIGERU MIYAMOTO Copyright © Evolutionary IT 2008 72
  • 73. Interesting Quote Video games are a waste of time for men with nothing else to do. RAY BRADBURY Salon.com, Aug. 29, 2001 Copyright © Evolutionary IT 2008 73
  • 74. Actually... November 2005 Nielsen Active Gamer Study A survey of 2,000 regular gamers, found that the U.S. games market is diversifying. The age group among male players has expanded significantly into the 25-40 age group. For casual online puzzle-style and simple mobile cell phone games, the gender divide is more or less equal between males and females. Females have been shown to be significantly attracted to playing certain online multi-user video games that offer a more communal experience, and small amount of young females have been shown to play “aggressive” games that are sometimes thought of as being "traditionally male" games. 41% of PC gamers are women. - ESRB Copyright © Evolutionary IT 2008 74
  • 75. Industry Facts ● ● ● Most estimate nearly $10 billion market it the U.S. alone.

Copyright © Evolutionary IT 2008 84
  • 85. Nexuiz server.cfg ● hostname – will be the name of your server. ● sv_motd – your message or insult of the day. ● Maxplayers – max # of players. ● ● ● Port – the port you want the server to run on. UDP 26000 is the default Nexuiz server port. sv_public – set server to public or not. rcon_password – set if you want remote management password. Copyright © Evolutionary IT 2008 85
  • 86. RCON ● ● ● ● Rcon allows remote administration of the server. Pick a strong password. Can login while on your client connected to the server or add rcon password to your client config. Rcon User Guide Copyright © Evolutionary IT 2008 86

  • 89. SSH Lockdown ● ● ● ● ● Don't open up SSH to the internet and choose a weak password! You may want to allow SSH from only 1 host on your LAN I.e. sudo ufw allow from 192.168.25.225 to 192.168.25.25 port 22 Consider running on different port, locking external firewall to specific address/network of your “management node, Key based Auth, Denyhosts, Port knocking or Single Packet Auth. It might be better to VPN into your PFSense box and then SSH to your server. Copyright © Evolutionary IT 2008 89
  • 90. PFSense ● ● ● Setup Inbound NAT/Port Forwarding rules for the ports we need for the server to work. Assuming 2 interfaces (LAN/WAN). If you have 3 interfaces you can setup LAN/WAN/DMZ). 26000 and 81 in the case of Nexuiz. Copyright © Evolutionary IT 2008 90
