Connect to a Mac Remote Desktop using VNC

Posted on November 3, 2006 by blandname

This will be a quick howto as it’s mostly a settings issue, but here goes:

Macs have come with a Remote Desktop server for quite some time now, and it’s great for using macs to manage macs remotely, though maybe not as nice as an NX or XMing solution.

When trying to manage an Apple computer using a Windows or Linux computer it’s a different story. When you attempt to open the connection the authorization works, but the window will close very quickly, with no apparent error.

The problem lies in the actual implementation of VNC in Apple’s Remote Desktop server (not to be confused with RDP – it’s MUCH slower). Apple has decided to only support one type of tiling, whereas most VNC clients will attempt to find the best solution in order to connect. Specifically, Apple uses HexTile, and if you specify this in the options or properties of your connection, it will work with no problems whatsoever.

If you’d like to make a .VNC configuration file in order to connect to your Mac server using a Windows VNC client (RealVNC used here), just take the following code and save it as a *.VNC configuration file, being careful to change the host from (null) to the remote Apple Remote Desktop server’s IP address (for example: 10.10.10.10).

[Connection]
Host=(null)
[Options]
UseLocalCursor=1
UseDesktopResize=1
FullScreen=0
FullColour=1
LowColourLevel=1
PreferredEncoding=hextile
AutoSelect=0
Shared=0
SendPtrEvents=1
SendKeyEvents=1
SendCutText=1
AcceptCutText=1
DisableWinKeys=1
Emulate3=0
PointerEventInterval=0
Monitor=
MenuKey=F8
AutoReconnect=1

I have tested this method on many Windows and Linux machines, using RealVNC, TightVNC, UltraVNC and even Chicken of the VNC for Mac OS X. It works fine, though I’d like to pound home again that I would really like to have the option to either tunnel application over SSH, or have some type of locally-accelerated RDP-compliant protocol (heck why not use LTSP 5.0?)
One can only dream…

Manage Linux Workstations Using Xming

Posted on October 19, 2006 by blandname

SSH is one powerful tool. You can do just about everything under the sun using an SSH login to a remote computer. SSH works very well in low-bandwidth situations like dialup, or satlinks.

But wakeup, we’re no longer in the 80s – people want GUIs, let’s give them fancy-pants graphics, bouncing cursors and silly linux wizards. Remotely.

Enter Xming, what I would name as top of my favorite applications. Xming is just like X over SSH, for dummies (or people who would rather spend more time working).

Xming allows you to connect to remote or local Linux workstations and servers and run full graphical applications on those remote machines on your local Windows computer.

Here’s how it works: all of the applications are run remotely, but when it comes to the graphics, the information that would invoke the graphics is sent to your local computer, not a bitmap or a sequence of bitmaps like VNC. Xming uses a local X server on your Windows computer in order to display your remote applications. This local X server is 2D accelerated, and it’s sometimes difficult to even notice that you are working remotely.

Since Xming can run in windowed or full-screen modes, you can establish thin client connections in this fashion, or you can publish applications Citrix-style.

Xming is completely free to install and setup. It is a great way to manage virtual machines, and in fact is often faster than Microsoft’s Virtual Server ActiveX control (surprised?), VMWare’s Virtual Machine view (even with VMWare tools!), and even Parallels speedy virtual machine view.

To set the whole thing up, you’ll need a computer running Microsoft Windows, one Linux box, a network connection between the two, but you won’t need much effort.

First install the Windows Xming server on your Windows computer. We’ll use Windows XP SP2 in this example, but it could easily be other varieties. Xming can be found on Sourceforge quite easily, download it, run the install (use defaults), and start XLauncher.

On the Linux computer this are slighlty more complicated, but not by much. For Gnome or KDE on Ubuntu Edgy, go to the System>Administration menu in your menu bar. In Administration, we’ll select login preferences as we’ll be setting up a new logon method (we’re using XDMCP). Select the Remote tab, and enable remote logon (same as local) to your Edgy Eft machine.

Now on your Windows machine, set up XLaunch to logon to your Linux machine using it’s IP address. Save the setting if you want, and connect. You will be presented with a logon screen to your Linux desktop!

9 Great, Free Applications that Work with Vista

Posted on October 11, 2006 by blandname

This is a list of my favorite Windows applications that I honestly couldn’t live without that also work on Microsoft Windows Vista RC as well, much to my surprise. All of the software is free to download and use, and in fact most of them are open source.

ConTEXT – ConTEXT is a free and lightweight editor for programming or can be used as a notepad replacement. ConTEXT supports find and replace in multiple files at once so changing one method in loads of files is no longer an issue. Works in Vista with no problems whatsoever.

Synergy – Synergy is like a software KVM, but only shares keyboard and mouse capabilities. Synergy is multiplatform, and I currently use it to have my keyboard and mouse work in Ubuntu, Vista, and my Mac Mini running Leopard with no problem at all! This way I get to use my favorite keyboard and mouse and get to free up some space on my desk at the same time.

VLC – VLC has been my favorite media player for years now. VLC comes with most of the codecs you will need to watch videos on your PC already. VLC is very lightweight, and JUST WORKS, something that can’t be said about many media players. The only issue with VLC in Vista is that it turns Aero Glass off while it is playing.

FileZilla – I use FileZilla to interface with clients that still haven’t moved to SCP. FileZilla is an open source FTP client that gets the job done, supporting drag and drop, SSL, and NAT to NAT connections. The only thing it is missing is FXP support, but that’s not really a big deal in my case. Works fine in Vista with no problems at all.

IMGBurn – I love IMGBurn. This is hands-down the easiest way to burn .IMG, .ISO and BIN/CUE disk images to backup CDs or DVDs. Free, open source, and awesome. Works a treat in Microsoft Vista Beta 2 as well.

WinSnap – I use WinSnap to make many of the screen shots you see on blandname. WinSnap supports full screen and windowed screen shots, and also allows for rotation and drop shadows if you feel the need.

Electric Sheep – I often refer to Electric Sheep as “the best screensaver ever”, but truth be told, it’s really a collection of computer-generated screensavers that allow users to vote on them using a Digg-like system. On Windows, Electric Sheep uses bit torrent to transfer the sheep data. Again, working just fine in Vista!

Xming – Xming is my prefered interface to remote Linux boxes. Xming is for Linux what RDP is for Windows – you get a local X server and acceleration that displays data from remote applications running on Linux machines. Tested more than a few times to a remote Ubuntu computer, and one Gentoo box with no caveats.

WinSCP3 – SCP is now my preferred file transfer method. Luckily my favorite client also works on Vista, or I may not have used it at all. Much like FileZilla, WinSCP3 has a very simple, streamlined interface that is feature-rich and gets the job done, even on Vista.

So there you have it: 9 free applications I couldn’t live without that work just fine on Vista, and make it easy for me to do my day-to-day tasks. Hopefully someday this list will include F-Spot and Amarok, but I’m happy with this as a start considering neither of them work on Windows XP SP2 either!
