The Problem A client makes extensive use of the The Cisco Network Access Control (NAC), a.k.a. Clean Access solution for their wi-fi enabled laptops. These systems are Active Directory domain members and prior to an AD upgrade, would boot and have a user logged in within 2-3 minutes. After the domain controllers were upgrades to Windows [...] SSL server certificates are mandatory for finance, e-commerce, and any site that wishes to protect data in transit. Tied to a fully qualified domain name, they also provide a level of non-repudiation. SSL in its more modern incarnation, transport layer security (TLS), is a very effective layer of security. A quick Google search for “web [...] For a very low cost, it’s easy to use StartSSL (Startcom) certificates on the Citrix NetScaler product line. This is includes the free NetScaler VPX Express edition. A lot of problems I see with others configuring the NetScaler is related to either self-signed certificates or the use of intermediate (e.g., chained) certificates. Using a Startcom [...] XenDesktop 4 has raised the bar for virtual desktop (VDI) solutions. It’s now easier to provide a virtual desktop to users on differing operation systems and platforms. And having Citrix on the iPhone / iPad is just amazing eye candy too. By default, all the tutorials for installing XenDesktop use the defaults. This means that [...] Recently I did a “few” upgrades to the home lab. Besides an upgrade to enhance shared storage for vSphere (my old NAS was at 502 days uptime), I took the opportunity to enable jumbo packets on my Dell PowerConnect 5324 and the new fire-and-forget Thecus N7700PRO NAS. As the basis for new lab infrastructure to [...] This is an update post to reflect the differences in vCenter 4.1 vs the older vCenter 25 install. The older post can be found here. Certain third party products such as XenDesktop respect the expiration date on the vCenter SSL certificate. The vSphere Client doesn’t mind so much, nor it appears do the vSphere (ESX/ESXi [...] I’d love to use Foxit’s super fast PDF iflter for my test SharePoint 2010 setup, but at $700, it’s not going to happen. However, the Adobe one works fine, after some regedit goodness. Looking online, there are lots of articles mentioning the SharePoint beta, but not the RTM. Here are the quick steps to get [...] Certain third party products such as XenDesktop respect the expiration date on the vCenter SSL certificate. The vSphere Client doesn’t mind so much, nor it appears does the ESX hosts, but when your VDIs suddenly can’t be reached, it’s a bad thing. By default, vCenter will create a self-signed certificate with just the host name. [...] VMware’s Update Manager has always been too complex and cumbersome for small installations. However, back in the EX 3.5 days, it at least worked. Late last year when vSphere 4 Update 1 came out, I once again tried using good ol’ Update Manager. [...] I love OS X and every iteration has gotten better and better. But every once in a while tasks that should be simple–aren’t. Take the case of trying to add a S/MIME certificate to the Keychain. In the past, simply double-clicking on the .p12 file would prompt for the passphrase and import it into the [...] |
