This webinar covered an introduction to the FreeBSD operating system. Some key points: - FreeBSD is a complete and stable UNIX-like operating system with a BSD license, known for reliability especially under high load. - It has a centralized development model and package management system separate from external software. - Features include the UFS and ZFS file systems, DTrace debugging tool, and support for SMP, 10Gbps networking, IPv6, and more. - The GLC Learning Center provides online training and workshops about FreeBSD and other technologies to improve IT education in Indonesia.

2. Several notes about webinar
• Silahkan angkat tangan anda jika ingin
bertanya
• Atau tuliskan pada chat box yang tersedia
• Don’t mess with audio

3. Agenda
• History of FreeBSD
• FreeBSD Features
• GLC Introduction
• FreeBSD Implementation
• Question and answer

4. What is FreeBSD?
• A complete Operating System. Not only kernel.
• It is UNIX (like)

5. FreeBSD History…

8. BSD License
Most liberal on earth:
• Don’t claim you wrote this.
• Don’t blame us if it breaks.
• Don’t use our name to promote your product.
Benefits:
- Easy to adopt new technology: ZFS, dtrace
- Easy to port to other system: Juniper, Cisco

9. FreeBSD development
• Less bazaar & democratic. no single figure.
• Core Team: 10 people -> management
• Committers: 500 people -> commit the source
code
• Contributor: thousands -> contibute
improvement codes
• Users -> you!!!

10. Other BSDs and their target
• NetBSD -> portability
• OpenBSD -> security
• Mac OS -> commercial, GUI
• DesktopBSD -> desktop
• Fressbie -> live CD

11. Other UNIXes
• Solaris/Opensolaris
• AIX
• Linux
• IRIX, HP-UX, Sinix (Siemens), Xenix (Microsoft)

12. UNIX-like OS…
UNIX but it’s not UNIX…
• Because of License
• The way software behave
Eg. *BSD, Linux

13. Why FreeBSD?
• Free, Open source, BSD license
• Stable, especially on high load
• Portability: x86, x86-64, Sparc, etc
• Hardware range: old-new
• Package management: ports, easy to upgrade
• Good Documentation
• Advanced Features: UFS, ZFS, Dtrace, SMP,
10Gbps optim, SCTP, BSM
• Thousands Collections of software

14. High load…?
last pid: 13129; load averages: 409.01, 407.73, 407.19 up
1+16:36:25 19:55:47
434 processes: 408 running, 24 sleeping, 2 zombie
CPU states: 93.8% user, 0.0% nice, 5.9% system, 0.2%
interrupt, 0.0% idle
Mem: 258M Active, 889M Inact, 224M Wired, 63M Cache, 162M
Buf, 3080K Free
Swap: 2048M Total, 92K Used, 2048M Free
Still responsive...

15. What you can do..
• Webserver: yahoo, sony
• Email service: yahoo
• Router: juniper, ISP router & firewall
• File & print: FTP
• DNS server: freedns.org, telco company
• Database: mysql & postgresql, hosting

16. Break…
Intro to GLC Learning Center

17. GLC Learning Center
• What: an organization that provides online
training, workshop, and webinar.
• When: since january 2008
• Vision: provide affordable training, workshop,
and webinar for indonesians
• Benefits: flexible, online, saving transport

18. GLC background
• Imrove Human Resources of indonesia.
• “lulusan IT banyak yang mengecewakan” ref:
detik.com, 16 january 2010
• Beberapa lulusan IT memang mengecewakan.
Ref: pengalaman pribadi
• Lack of Indonesian expatriate
• Lack of certified engineer

19. GLC training, workshop
• Operating System: fundamental, system
admin, network & security admin. Setara
dengan Sun, RH training
• Networking & Telco: computer network basic
(setara CNAP), GSM fundamental, UMTS,
Signalling
• Database: SQL fundamental, oracle, mysql,
postgresql
• Programming: Java, shell, php-mysql

20. Next events…

21. FreeBSD’s “Base System”
An entire system which includes:
• Kernel
• Some userland packages. Eg. libc, openssh, ssl,
etc
With
• Single centralized development model
• Separate from external packages. Eg. Php,
mysql, apache

22. FreeBSD release Engineering
• “Base system” is under revision control CVS.
You can always get the latest development
code.
• 2 development lines:
– CURRENT eg. FreeBSD 9.0
– STABLE eg. FreeBSD 8.0
Stable means less bug & doesn’t have major
changes

23. FreeBSD Features
• UFS, ZFS
• Dtrace
• SMP up to over 8 cores
• 10Gbps optimization
• SCTP, IPv6 improvements
• BSM, jail
• Ports collection
• Hardware platform: tier1, tier2, tier3, tier4
• Firewall: IPFW, ipf, pf

24. FreeBSD ZFS (copy-on-write)

25. Some (untrue) Myths…
• BSD needs Special Hardware…
• Software availability
• Lack of Support…
• Difficult to learn…

26. Other resources
• FreeBSD.org
• Google: “why did we choose FreeBSD”
