disabling snmpXdmid on Solaris 10 (dmi)
I still find the service manager stuff confusing.
"On a recent server build project we ran into a security scan that surprised us with a mandate that snmpXdmid be disabled. The alleged vulnerability is based on a buffer overflow that originated in the days of Solaris 8 as documented in CIAC Information Bulleting l-065 and SunSolve Security bulletin #00207. The details aren't important to this story other than finding it entertaining to respond to a Solaris 8 vulnerability on a Solaris 10 build. I'll save my thoughts on the corporate world's implementation of automated scanning for another post."

Install OpenWRT, Chillispot, FreeRadius
If you have ever tried to implement one of the hotspot HowTos on this and other sites, it might have dawned on you that this is not an easy feat to accomplish. Amazingly most solutions also leave out the most important part how to get paid by the punters using the hotspot. Some will offer prepaid solution or access tickets that need to be printed, but this will require staff being involved on the premises. And in particular, once you want to offer a professional service and not just a toy concept it gets tricky and expensive. Just imagine all the servers you need to provide redundant and load balanced freeradius, mysql and web servers. It is generally not worth the effort and expense for just one hotspot unless of course you are willing to accept outages, unhappy customers etc

Holy smokes! A holey file!
I like ZFS. Lots of cools stuff. Even though if we upgraded to Solaris 10 at work we would probably not implement it. SANs take away a lot of the reasons for it, least that is how it looks to me.
"First, let's review a little bit about how ZFS works. By default, when ZFS writes anything, it generates a checksum which is recorded someplace else, presumably safe. Actually, the checksum is recorded at least twice, just to be doubly sure it is correct. And that record is also checksummed. Back to the story, the checksum is computed on a block, not for the whole file. This is an important distinction which will come into play later. If we perform a storage pool scrub, ZFS will find the broken file and report it to you (see above), which is a good thing -- much better than simply ignoring it, like many other file systems will do."

Happy 15th birthday NetBSD!

The NetBSD Project celebrates its 15th anniversary: The first commits were made to the NetBSD source code repository on March 21, 1993, and the first release of the NetBSD Operating System, NetBSD 0.8, was announced on USENET shortly thereafter. Throughout the past fifteen years, NetBSD has increased the portability and security of the 4.4BSD operating system on which NetBSD was based, and added support for new processor and system families, while enhancing the system's performance to such an extent that NetBSD has become known as the most portable operating system in the world. Innovations in the storage, networking and virtualization arena have been added, and much work has been done recently on performance, especially with multi-core and multi-threaded machines in mind.

The NetBSD developers also share their plans for NetBSD 5.0 and 6.0: Roadmaps covering storage, networking, virtualization and the system itself have been published.

Prepare a Self-Installing Drive for Blade Servers
Build a bootable, self-installing hard disk drive for an IBM BladeCenter HS20 blade server running SUSE Linux Enterprise Server 10 following these nine easy steps. When the system boots from this drive for the first time, it automatically begins to install Linux on the disk, which eases the task of preloading the operating system and lightens user workload.

DTraceToolkit in MacOS X
Dtrace looks like a great tool. Perhaps the best thing to come out in a while for troubleshooting.
"Apple included DTrace in MacOS X 10.5 (Leopard), released in October 2007. It's great to have DTrace available in MacOS X for its powerful application and kernel performance analysis. To think that there is now another kernel we can examine using DTrace is exciting - it's like discovering a new planet in the solar system."

A look into Solaris, by Derek Crudgington
"Solaris x86 jumpstart on ISC DHCP If you are using the Solaris dhcp server, stop now. Save yourself hours of time of trying to figure out pntadm, dhtadm, and just use ISC DHCP on Solaris. It's very simple, painless, and you will be glad you did."
