Reading Time: < 1 minute Neil Anderson, from Flackbox, has build an amazing free Cisco CCNA Lab Guide recently which can be used to pass the CCNA exam or as a configuration reference for Cisco routers and switches. There’s a few free guides online but they all cover old out of date exam topics and aren’t great quality, but this is guide really complete (350+ pages), up to date, with good quality and simple, which people can use completely for free.

Reading Time: 2 minutes Several people are disabling IPv6 support in ESXi for different reasons: because of the minimum privilege principle (if you are not using a service, why you have to keep it enabled?) or simple because they don’t want any IPv6 address in the network. On Linux and Windows systems is become very difficult disable it and Microsoft itself does not recommend disabling IPV6: ” We do not recommend that you disable IPv6 or its components, or some Windows components may not function.” (https://support.microsoft.com/en-us/kb/929852)
Reading Time: 2 minutes As promised in the last VMworld, now VMware has introduced two new less-expensive versions of its NSX product targeted for the mid-enterprise. Also on NSX there are now different editions with different prices and, of course, features. The full version will be the Enterprise one (sigh… on vSphere Enterprise has gone, wasn’t better call it Enterprise Plus), the intermediate Advanced and the starter just Standard. No Essential or Essential Plus, but will be difficult and non sense (yet) apply this kind of technology to the small business.
Reading Time: 3 minutes VMware best practices for virtual networking, starting with vSphere 5, usually recommend the vmxnet3 virtual NIC adapter for all VMs with a “recent” operating systems: starting from NT 6.0 (Vista and Windows Server 2008) for Windows and for Linux that include this driver in the kernel, and for virtual machines version 7 and later.

Historically there were some […]

The new version will add some new features and will support new switches […]
Reading Time: 5 minutes One issue about VMware NSX it that it does not exist an evaluation or a trial code in order to study and test it. This because the code is still on a Nicira web site and is much more restricted compared to other VMware code. Also VMware partner may be not entitled to download it, unless they don’t have the NSX competency. Individual can got an access only through one of the NSX official course: I’ve take the ICM on NSX 6.0 and the access on Nicira web site was granted me at the end […]
