Lippis Report: A new era in networking with virtualization

The three pillars of IT computing, networking and storage have always been embraced in an odd dance of shifting functionality responsibility as Moore’s Law continues to break down, blur and redistribute lines of responsibility across the three pillars in an effort to increase application performance. For example, networking has always off loaded tasks that were once done by computers. In fact some of the first routers were DEC mini and micro VAX systems back in the early 80s. This trend continues today with more computer functions such as load balancing, caching, security and certain aspects of computer operations migrating to the network fabric. Access to and configuration of storage has gone through huge changes over the years, thanks to networking, with the introduction of Network Attached Storage (NAS) and Storage Area Network (SAN). Computing functionality, applications acceleration, storage access and many other functions have shifted into the network fabric. The latest shift is network virtualization where better utilization, increased flexibility and application performance is promised in the data center and the overall enterprise.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Splunk that!

Saw this advert on Slashdot and went on to look for it and found the tour pretty neat to look at. Check out the demo too! So why would I need it? WHY NOT? I'd say. As an organization grows , new services, new data comes by, new logs start accumulating on the servers and it becomes increasingly difficult to look at all those logs, leave alone that you'd have time to read them and who cares about analysis as the time to look for those log files already makes your day, isn't it? Well a solution like this is a cool option to have your sysadmins/operators look at ONE PLACE and thus you don't have your administrators lurking around in your physical servers and *accidentally* messing up things there. Go ahead and give it a shot by downloading it and testing it. I'll give it a shot myself! Ok so I went ahead and installed it. Do this... [root@tarrydev Software]# ./splunk-Server-1.0.1-linux-installer.bin to install and this (if you screw up) [root@tarrydev Software]# /op

Virtualization is hot and sexy!

If this does not convince you to virtualize, believe me, nothing will :-) As you will hear these gorgeous women mention VMware, Akkori, Pano Logic, Microsoft and VKernel. They forgot to mention rackspace ;-) virtualization girl video I'm convinced, aren't you? Check out their site as well!
