Changing the IP Address in Solaris 10 U3

Changing the IP address of a system running Solaris (Solaris 10, specifically) is different than a lot of other operating systems out there. Really, all you have to do is just edit a few files and then take the interface down and back up again. However, there seems to be a “gotcha” with Solaris 10. (I don’t know how far back this procedure goes—it is unclear to me if this is new to Solaris 10, or if it extends back to Solaris 8 or 9.)

Now Three Word Zero-Day Exploits

More information on the various zero-day exploits can be found at the following web sites:

iSCSI from NetApp to ESX Server

Network Appliance storage systems are becoming more and more visible in VMware deployments due to their iSCSI support and the synergies that are gained when combining VMware’s functionality with the functionality of Network Appliance’s Data ONTAP operating system. I’ll touch on those synergies in a future article, but in the meantime here’s how to configure a NetApp storage system to present iSCSI storage to one or more servers running ESX Server.

VM Portability, Round 3

Having first tested VM portability from VMware Workstation (on Windows) to VMware Fusion (on Mac OS X), then portability from ESX Server to VMware Fusion, the next logical step was VMware Fusion to ESX Server. I ran into one surprise but, as I expected, the process worked without any major hiccups.

802.1x Integration with Active Directory

The idea behind 802.1x is to provide Layer 2 authentication; that is, to authenticate LAN clients at the Ethernet layer. (This is before the client gets a DHCP lease or anything of that nature.) With 802.1x in place, rogue users can’t just tap into a physical connection on the network. In order to gain network connectivity, the device must authenticate before network traffic is allowed.

VM Portability Again

The idea was to take a VM running Windows Server 2003 R2 off one of the ESX servers and port it over to VMware Fusion on my MacBook Pro. If that worked (and I fully expected that it would), then I’d try reversing the process. In particular, I’d love to move that same VM I moved last week over to the VI3 server farm from my MBP (it’s running the NetApp Data ONTAP Simulator and I could really use it running on the servers). This attempt would be a precursor to that attempt.

Word Zero-Day Attack Alert

Microsoft has started alerting customers of the new Word zero-day attack via a posting on the MSRC blog and by posting Microsoft Security Advisory 929433, which describes the attack, the vulnerability, and suggested actions.

iSCSI on Solaris 10 x86

Given that I’m neither a Solaris expert (yet) nor an iSCSI expert (yet), I knew that it would be a bit of a challenge to make this work. Fortunately, a found a very useful blog posting by Frank Berger that gave me the framework I needed to get started. From there, Sun’s documentation provided the rest of the necessary details. Perhaps this documentation will prove moderately useful as well.
