yesthattomhttp://www.BSDCertification.com -- Lots of interesting things going on. Dru Lavigne was the speaker.
Network Management Tools -- I use Cricket already but I really need to use NetFlow. I’ve known about it for ages, but I haven’t put it to use. His suggestion is to install it and have it collect data for a week and then query to find out what traffic do you not expect to see? (i.e. eliminate port 25, 80, 443 and 53 and see what’s left)
DKIM - Domain Keys Identified Mail -- Eric Allman filled in for a speaker that couldn’t arrive. He talked about DKIM which is a proposal for hosts to sign mail on behalf of the senders. It could be used for a basis for numerous things, such as anti-SPAM systems. (link)
Lunch with Kirk McKusick, Trish, George V. Neville-Neil at a Chinese restaurant called Olly.
CARP implementation for OpenBSD -- Jason Dixon showed a demo of CARP (the fail-over protocol). He also showed an IPSEC VPN tunnel failover feature that will be in the new release. I can now do tons of features that most commercial systems can’t yet do.
DragonFlyBSD -- Jeffrey Hsu talked about how DragonFlyBSD takes FreeBSD 4.10, adds ALTQ + Pkgsrc from NetBSD, good stuff from OpenBSD, and adds a lot of new functionality. Their big focus is improvements that help NUMA systems. NUMA is quickly replacing SMP for having multiple CPUs in the same box. (NUMA was what made SGI do so well on benchmarks 10 years ago and now everyone else is finally catching up.) He also covered a lot of the networking improvements. (He was briefer about the parts of the system that he wasn’t directly involved in, but there are improvements to the process system and so on). The ISO is bootable and doesn’t touch your hard disk, so you can test out DragonFlyBSD easily.
Break
PostgresSQL In BSD Land -- Bruce Momjian For a 1-hour talk, he spent the first 30 minutes talking about who’s who in the project, companies that have given support, and such. Version 8.0 gave features that put PostgesSQL in the ring to really compete with commercial systems, really entering “enterprise” level features. 8.1 includes: bitmap merging of indexes (rather than pre-index on every combination of fields you might ever need, indexes can combine dynamically; important for data warehousing), two-phase commit (rollback if transaction on two machines if both don’t complete), “automatic vacuum”, better min/max, Multiple OUT params (for Oracle compatibility) in functions, shared row locks, roles merge users and groups (from the SQL standard... role-based permissions rather than groups), and other features.
Keynote: Enhancements to the Fast Filesystem to Support Multi-Terabyte Storage Systems by Kirk McKusick -- He talked about the development of the UFS2 file system, which supports 64-bit block numbers. Since he was changing the format, he took the time to change a bunch of other things. The same code reads UFS1 and UFS2 partitions and does the right thing. (I didn’t take many notes because I wanted to pay attention but I assure you it was an excellent and educational talk. Kirk’s a great speaker.)
