Hanging Around #vmware

I’m not really sure why, but for some reason I got on a kick to start using IRC. So, for the last week or so, I’ve been regularly logging in to irc.freenode.net using Colloquy (a really great Mac OS X IRC client, by the way) and hanging around in the #vmware channel, helping people with their VMware-related problems and questions—and learning a little bit in the process.

ESX Server-AD Integration

Although much of the administration of servers running VMware ESX Server 3.0 will occur in the Windows-based Virtual Infrastructure client connected to a VirtualCenter server, there are times when it is quicker or easier to perform an administrative task directly on the ESX Server itself—either via the command-line interface (CLI) or via the VI client authenticating directly against the ESX Server. The problem with this is that, by default, administrators will have to use different credentials when connecting the VI client to ESX Server directly. In addition, these credentials must be managed separately from Active Directory, and separately on each individual ESX Server. As the number of ESX Servers in a farm grows, this can quickly become an administrative nightmare.

UAC and ktpass.exe

User Account Control (UAC) is a feature new to Windows Vista and Windows Server 2008 that is designed to help protect Windows-based systems against processes running with administrative permissions. It’s a great idea, but the implementation is, in my humble opinion, a bit flawed.

Linux-AD Integration with Windows Server 2008

In the event that your organization is considering a migration later this year (or next?) to Windows Server 2008 (formerly “Longhorn”), here are some instructions for integrating Linux login requests against Active Directory on Windows Server 2008. These instructions are based on Linux-AD Integration, Version 4 and utilize Kerberos, LDAP, and Samba.

Samba and Windows Server 2008 Interoperability

Samba, as I’m sure you already know, is an open source implementation of SMB/CIFS for UNIX, Linux, and similar operating systems. I’ve found Samba to be extremely helpful in providing some assistance for integration into Active Directory, as evidenced by these articles:

NIS on Windows Server 2008

Even though NIS is installed as part of the “Identity Management for UNIX” role service (part of the Active Directory Domain Services role) in Windows Server 2008, it appears that some additional steps are required in order to make it work as expected. If anyone has any additional information they’d like to share on this particular issue, please speak up in the comments.

Mac Usenet Applications

I’m a multi-protocol kind of guy. What does that mean? Basically, it means that I use more than just a web browser. Typically, I have multiple Internet clients running at any given time—a browser (typically Camino, but sometimes Safari), an RSS reader (NetNewsWire), an IM client (Adium), Cocoalicious (for managing del.icio.us bookmarks), an IRC client (Colloquy), and an e-mail client. In each of these areas, there are high-quality applications available to choose from. For example, if I didn’t like Camino or Safari, I could always switch to Opera or Firefox; if I didn’t like NetNewsWire, I could switch to NewsFire, Shrook, or Vienna. I have options.

Authenticating to Cisco IOS via Active Directory

The following configuration will enable you to authenticate login requests to Cisco equipment running IOS against Active Directory. This would, for example, allow you to centralize the authentication of your Cisco-based network infrastructure against Active Directory.

ESX iSCSI Basic Configuration from the CLI

Sometimes, I find it better/faster/easier to perform tasks from the command-line interface (CLI) than going through a GUI. So, the other day, I needed to setup a new VMware ESX Server for iSCSI storage, and thought I’d document the commands I used to set that up.

NFS Help

I like to think that I’m a fairly intelligent guy, able to pick up most things reasonably quickly given the opportunity. After all, I transitioned from a Windows-only SE into an SE with a good reputation for VMware ESX Server, various Linux flavors, Mac OS X, and some Cisco configuration (hey, if you can do GRE tunnels with IPSec encryption, you’re not too shabby with IOS). But I’m having a real problem with NFS.
