I have been wanting a better way to analyze the data that is recorded onto my CPAP machine’s SD card. The Philips Respironics mobile app leaves a lot to be desired. Especially, if you’re highly interested in looking at ALL THE DATA like I am.
I was hoping I would be able to take the RAW data and import it into Excel for analysis. Of course, upon inserting the SD card into my computer, I realized that was a silly idea. The data is in a format that is either proprietary or simply foreign to me.
Fortunately, for both you and myself, someone has already done the hard work and developed a desktop application (that works on all major platforms) that will allow you to import the data from your SD card and review the information visually.
For me, I had 1,275 days of sleep data stored on my SD card. I find it fascinating to be able to look at all of this information at once, in a visual format.
As recommended by the application, I do also highly recommend write protecting your SD card before inserting it into your computer. Some operating systems will add additional files to a drive when it is inserted. This may render the card unreadable by your CPAP device.
OSCAR is a fork of SleepyHead. It appears as though there was some contention between the original application developer and the ApneaBoard.com community. Therefore, SleepyHead development ceased and the OSCAR fork was created.
This post is in response to me thinking that people may be wondering how to use Chocolately, as discussed in “Getting Started with Chocolatey”, to install applications to a remote Windows 7, 8 or 10 computer.
The quickest solution is to utilize PsExec’s remote command prompt feature.
If you are in a workgroup environment rather than a domain environment you will most likely need to make a registry modification in order to be able to connect to a remote computer using PsExec.
Note: All registry edits should be performed with care. A backup of the registry is highly recommended before performing any registry edits.
Navigate to the following location in the Windows registry:HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\System
• Right click.
• Choose New -> DWORD (32-bit) value.
• Change of the name of the newly created key to: LocalAccountTokenFilterPolicy
• Double click on the newly created key and change the value to: 1
Modifying the above registry setting allows full credentials to be passed between the local and the remote computers in a workgroup environment. I do not have access to a domain environment where I can test whether this registry modification is necessary in a domain environment or not. Please feel free to comment if you have the answer to this.
If you do not already have PsExec installed onto your own computer you can easily do so via Chocolatey using the following command: choco install sysinternals -y
Once you have installed the Windows Sysinternals suite you can open an admin command prompt and enter the following command: psexec \\REMOTECOMPUTERNAME cmd
If this is your first use of PsExec you will be prompted to accept the license agreement.
If your local credentials match the credentials of an account on the remote computer that has administrator credentials you should be connected without any problems. If your local account is different than your account on the remote computer that has administrator credentials you will have to enter a different command to connect remotely: psexec \\REMOTECOMPUTERNAME -u USERNAME cmd
If PsExec is able to successfully connect to the remote computer you should be prompted for the password of the user account that you specified. If the remote logon is successful you will be taken to a remote command prompt. You can issue the same commands here as if you were sitting directly in front of the computer. You can use this to install software via Chocolatey as discussed in the previous post.
To confirm that you are on another computer you can issue the command hostname
When you have finished you can enter exit and you will be returned to your local command prompt.
What is Chocolatey and why would I want to use it?
Chocolate: “A typically sweet, usually brown, food preparation of Theobroma cacao seeds, roasted and ground, often flavored, as with vanilla. It is made in the form of a liquid, paste, or in a block, or used as a flavoring ingredient in other foods.” – Entry for Chocolate on Wikipedia
If you read my previous article you probably think I really do hate Windows Phone 8.1, but I don’t. In fact, I actually love it. I think it is one of the most compelling mobile operating systems that I have ever used. It’s definitely not without its flaws, but please allow me to tell you why I think more people should give it a chance.
The operating system is extremely customizable, but there is a limit. That limit is where I get frustrated.
Example 1, Transparent Tiles: Finally, you have the ability to add a background image to your Start screen. This option makes many of the icons on the Start screen transparent so that you can see through to your background image. However, not all application icons become transparent. You’re left with that Fisher Price look we’ve become familiar with from Microsoft, from the Windows XP and the Windows 8.1 desktop operating systems. I personally want all of the icons to be transparent so the background image can shine through. Microsoft isn’t entirely to blame for this. They give developers the option to include transparent tile images for their applications. More developers are, but there are some that seem extremely stubborn in releasing a transparent icon for their application. They demand that their icon stand out like a sore thumb among all of the other beautiful transparent tiles. It is usually the social network sites that INSIST on this.
Example 2, Live Tiles: Simple live tiles that alert me to the number of unread messages or missed calls, I am fine with those. However, I absolutely hate live tiles that cycle through an entire news feed. I hate looking at my Start screen with the desire to scream “SHOW ME THE MONEY” as if it were a slot machine. There is one exception to this frustration. I am fine with the stock weather app cycling through the weather report. I keep it at the bottom of the Start screen, below all of the beautiful transparent tiles. I can’t keep all of the blinky, blinky apps at the bottom of the Start screen though. Ok, yes, technically I could, but that would look terrible and be terrible from a usability perspective. Again, this isn’t entirely Microsoft’s fault. They do give developers the ability to allow users to turn off their application’s live tile. It seems as though some application developers think their content is so important it must stare me in the face as soon as I unlock my phone! There are some media outlets, I’m looking at you CNET, that insist on having constantly updated information on their tile, no matter how small you make the tile.
Feed Resiliency and OS Navigation
Windows Phone 8.1 is ABSOLUTELY TERRIBLE at remembering where you were on the previous page when you hit the back button. The best example of this is the Facebook application (which is developed by Microsoft because Facebook doesn’t believe in the Windows Phone platform). As I am scrolling through my news feed I will inevitably come across a link that a friend or a news outlet has posted. I will click the link and read the article. When I press the back button to go back to Facebook and my news feed I expect to be able to pick up where I left off. That doesn’t seem like too much to ask for, does it? Well, I guess it is because I am instead taken ALL THE WAY BACK TO THE TOP OF MY NEWS FEED. That is like having to start reading a traditional newspaper from the front page after you’ve read an article! This is, quite possibly, my biggest problem with the operating system. It is one of the most frustrating problems because it affects me constantly. The good news is that there are some applications that are good at remembering where you were. Not all of them make me want to bang the phone on sharp objects and run it over with my car!
Side note: While I do have major gripes about the Facebook application that the Microsoft team is developing. I have to also thank them for stepping up where Facebook won’t.
When I am finally ready to be taken back to the top of the page I am on, there is not a universal gesture for returning to the top. Most mobile operating systems allow you to double tap the top of the screen to return to the page you’re on, but not Windows Phone OS. If the application developer hasn’t added a method for returning to the top in their application you will be doing a lot of scrolling to get back to the top, refreshing the page or closing and re-opening the application you’re in.
There are some sections of the operating system that provide you with a quick way to jump down the page to the section you need to get to. Example: From the Start screen you can select a letter and then select the first letter of the application you’re trying to get to. Tapping the letter ‘S’ allows you to get to the applications that start with the letter ‘S’ very quickly. Unfortunately, not all applications provide this feature. Looking through long lists of folders in the Windows Phone Mail client, this feature would be extremely useful. This must be an easy feature to add, but I don’t know why Microsoft didn’t add it wherever they could in their own applications.
Limited Network Share Support
I hate that I have to install a third party application to access network shares on a Windows Server from my Windows Phone. I guess their intention is for you to store everything on OneDrive? I would love to have my favorite home network shares automatically mount on my phone when I connect to my home network’s wireless access point. I am sure that is asking for way too much! I won’t hold my breath waiting for that wishlist item!
For years, I have been able to watch a plethora of media file types across my home network by simply mapping to the share. Rarely, have I ever had to copy the file down to my device to watch the file. However, many file types that are supported by Windows Phone simply will not play unless you copy them to your device. It seems as though iOS and Android are better at buffering the data stream from server to device than Windows Phone is. WMV files that I attempted to stream to my Windows Phone were the worst. I would get a few seconds of video, playback would begin to buffer, but playback would never resume. This was not a problem from Android or iOS (with the same .wmv file).
How the **** Do I Copy and Paste Text?
It was the season for shipping and receiving when I first started testing Windows Phone OS. My inbox was full of tracking numbers. I wanted to copy and paste these tracking numbers from the mail client into the tracking application. One would think that you could simply tap, double tap or simply hold your finger on the area you want to select to get a highlighter to appear, but one would be wrong! In the Windows Phone Mail client you have to hit the reply button in order to copy and paste text from an email message. Thankfully, in other applications such as Internet Explorer, copy and paste doesn’t appear to be so frustrating.
Lack of Default Stock Applications
I am sure by now all of you have seen the image where someone has laid out all of the devices that a modern mobile phone has replaced. Microsoft forgot to include a few items from that image: Compass, level, world clock, voice recorder, stop watch and a note pad. I can deal with the omission of a compass because there is a stock map application. Also, the Lumia 635 does not have a built-in compass. I can deal with the omission of a level, but it is still a nice feature to have. It is great when you don’t have a spirit/bubble level handy when taking pictures. I think a world clock, stop watch and alarm should be combined into one application. Yes, the phone does include Microsoft OneNote for notes, but I hate it. I guess I am simply one of those people that “doesn’t get it.” Perhaps if I took a class and learned how to use it and all of its features I would learn to love it. However, all I really want is an application that allows me to take quick notes and have those notes sync across all of my devices via OneDrive. It took a few days to get all of these features onto my phone. Microsoft does provide applications for some of these features, but you have to hunt for them in the Store.
Lack of Security Applications
There does not appear to be a built-in mechanism for scanning for viruses. It doesn’t appear as though there are any reputable solutions in the Store either. Being a Windows OS based device, I would think it would be a necessity. This seems like the perfect opportunity for Microsoft to release a version of Windows Defender for Windows Phone.
The OS also does not provide any security for your SD card. Anyone can pull the card from your device and access the contents. There are no options for encrypting the data on your card.
After a few days of having the device I noticed that in the Wi-Fi Sense application the option for “Connect to Wi-Fi hotspots” was on by default. I would love it if we lived in a world where everyone who has an open WiFi access point had good intentions, but we don’t. I highly recommend turning this off. You’re phone will still automatically connect to the networks you intentionally connect to (i.e. your home network.
Speaking of security. One of my goals for 2015 is to be more secure. To do that I intend on utilizing a VPN while using public WiFi. According to Microsoft the Windows Phone VPN client supports IKEv2 or L2TP with IPSec. I attempted to create a VPN using Windows Server, which should support IKEv2, but I was never successful in getting the Windows Phone to connect to the VPN server. I won’t blame anyone but myself for this. I’m sure I just need to learn more about it. Unfortunately, despite all of the documentation that states the option for “L2TP with IPSec” should be an option, it is not.
You have tasks to complete, but Cortana won’t tell you about them.
First, I find it completely absurd that tasks are hiding under the calendar. Once you are in the calendar application you click on the “…” menu and then click on tasks to access them. I feel as though tasks should be its own application.
Second, you can add tasks all day long. However, if you ask Cortana what tasks you have, she won’t see any at all. If you ask Cortana to remind you to do something at some point during the day she will gladly create a calendar reminder and you will be reminded. Tasks though, they don’t seem to be relevant in Cortana’s world.
Miracast Is The Way Of The Future
If you have a TV, gaming console or some other set-top box equipped with Miracast you can stream content to those devices from Windows Phone. Supposedly. I don’t have any Miracast devices in the house to test this feature with.
I did play with the “Project My Screen App” app to mirror my phone’s display to a Windows desktop. Unfortunately, I was only able to get it to work while having the phone tethered to a computer via USB cable. I can see a lot of uses for this feature (especially in the classroom).
I am disappointed that DLNA devices are not supported for streaming content to. Since Windows 7 the “Play To” feature has been equipped with the ability to stream content to DLNA certified devices. It is sad to see that this was not included in Windows Phone.
One would think that Microsoft could simply allow a Windows PC to act as a projector for a Windows Phone, but no.
USB on the Go Is Not Available
I would love to be able to connect a USB on the Go cable to my Windows Phone so I can connect a card reader or a USB flash drive. There are many uses for this. Sometimes you simply don’t have access to a computer or a WiFi connection. I have had the occasion where someone has handed me a USB flash drive and I am not able to view the files until I get home. USB on the Go would solve this problem. I could connect the flash drive and provided that it wouldn’t take too long I could upload the files to OneDrive and hand the drive back to its owner. USB on the Go cables are supported on Windows 8.1, so I don’t understand why this feature was stripped from the mobile operating system. I can’t see it taking up that much space.
I, like Steve Jobs, HATE Adobe Flash
Browsing websites on my iPhone I got spoiled by not having random audio coming from some hidden location in a webpage. Flash simply wasn’t supported in iOS. When clicking a YouTube video link the MP4 version was streamed instead. In a separate application with accessible controls. It was a beautiful thing. Now, like on the desktop, I have to fight the myriad of flash popups and banners. Flash videos play automatically and inside the browser windows. Some of the players built into the webpage are absolutely atrocious. You can barely access their controls because they weren’t built for mobile clients.
Speaking of YouTube. The stock YouTube application is terrible. Absolutely awful. It is simply a wrapper application that utilizes Internet Explorer. Look for a third party client for a better YouTube experience.
Check Your Backup Settings
This is just a personal preference, but if you look at the backup settings, by default photos and videos are only set to upload a “Good quality” version. I personally prefer to wait until I am on WiFi to allow pictures and videos to be backed up so that the “Best quality” version will be uploaded. I would rather have the peace of mind of knowing that the full resolution version has been backed up instead of a lower quality version.
I also highly recommend enabling the settings and application backup to the cloud.
Where the **** is the Lumia Denim Update?
The Lumia Denim update was announced several months ago. Since that time several Lumia devices have started to receive the update. Unlike Apple, Microsoft is not rolling out the update to all of the Lumia handsets at once. Instead, they are rolling it out to a few devices at a time. Unfortunately, when you have a ton of different devices to support, it is much harder to roll out a software update to all of those devices. This is something I will have to get use to on this platform.
OneDrive.com is TERRIBLE
I could write an entire blog entry about why I think OneDrive.com is terrible, but I don’t want to induce a heart attack. I hate comparing everything in Windows Phone OS to my experience with Apple iOS, but seriously, iCloud.com is phenomenal. Don’t get me wrong! There are a ton of features I would love to see implemented on iCloud.com, but compared to OneDrive.com, Apple got it right! Microsoft has some SERIOUS work to do with OneDrive.com! For a start, why must everything load in a separate window?
Having an online component, that works beautifully, allows users to manage their information much more easily and from any location, from any device, without having to install any software. iCloud.com is beautiful and each application available on the site is essentially a replica of the mobile client. Sometimes you don’t want to tap data into your phone or your tablet. Sometimes you want to sit at your computer to update your contacts or calendar items. Not everyone wants to use Microsoft Outlook. You won’t always be on your home computer.
While OneDrive.com does provide the same functionality as iCloud.com, I very seriously hope Microsoft invests some money into improving it.
Lack of Applications and Hardware Accessories
When I first started investigating the possibility of switching to Windows Phone, one of the biggest complaints I heard from other users is that there is a major lack of applications. While yes, I have found that there are a lot of companies that I would like to see applications from, I have been able to find applications from third parties to get me by. Sometimes the applications from the third parties are better than the application I had experience with on iOS or Android.
The lack of applications is not the fault of Microsoft. As I mentioned earlier in this article, Microsoft is developing a Facebook application on their own. Facebook has released one Windows Phone application for Messenger. They could VERY EASILY release an application for Facebook. Google has released one application for Windows Phone. It only provides one feature, searching Google. Yes, there is voice support, but nothing more. Why bother when asking Cortana is faster? I wish they would develop their own Google+ client for Windows Phone!
Windows Phone adoption is on the rise thanks to Microsoft introducing low-cost smartphones. This trend will only continue. Hopefully, at some point in the near future, these companies will see the benefits of offering their services to Windows Phone users. Microsoft, on the other hand, has been trying to get their applications and services into as many user’s hands as possible. Whether they are using iOS or Android devices.
During my conversion to Windows Phone I had to look for suitable replacements for applications that I used on iOS. On iOS I used a lot of remote applications to control playback on my media center PC. Apple has a good one for iTunes. Thankfully, there is a good one available for VLC Media Player on Windows Phone. Unfortunately, I don’t see the same type of application from Microsoft for Windows Media Center, Xbox Music or Xbox Videos.
It is amazing how many add-on devices you can get for an iPhone these days. There are add-on camera lenses that allow you to take 360° photos and videos. There are meters, readers and all kinds of measurement add-on devices that you can get. Unfortunately, I fear it will be a very long time before any Windows Phone enjoys these same wonderful accessories. Thankfully, I’m hanging onto our old iPhones.
When I am working from my Raspberry Pi (RasPi) I am usually connecting to it using SSH or some other method that doesn’t require a GUI. However, when I do need access to the GUI, I don’t want to have to connect a display directly to the RasPi. For a while I had been connecting to the RasPi using a VNC connection. While it does work pretty well I soon wanted something with richer output. I remembered that Mobatek had an application called MobaXterm that might suit my needs better. I headed over to their website, downloaded a copy of the free version and set about trying to use it to connect to my RasPi through X11 forwarding. After I got it to work I was very pleased with the results and the added functionality that MobaXterm adds. The rest of this entry is instructions for connecting MobaXterm to the RasPi through X11 forwarding. Enjoy!
First, you will need to download and extract a copy of MobaXterm (as of 2/9/2013 the current version is 6.1). Once you have extracted the files, double click on MobaXterm_Personal_6.1
Click on the Sessions button at the top of the window. Choose New Session. Choose SSH as the session type. In the Host field enter the IP address of your RasPi. Leave the port set to 22. You can also at this point enter the username that you will be using. Make sure that X11-Forwarding is checked. Choose “LXDE desktop” for the remote environment type. Click on OK at the bottom.
Once you click on OK you will see an X11 window open on your desktop. You may have to move it out of the way to enter credentials into the SSH window. Once you enter credentials and choose whether or not you want to save your password you should then (after a couple of moments) see the desktop of your RasPi.
NOTE: I am using the Raspian “wheezy” OS on my Raspberry Pi. However, the instructions above will most likely work for a majority of Linux distributions as long as XDMCP login is enabled.
One of the most critical aspects of setting up a new system is creating a system image. Especially for Windows systems. Who wants to install updates and reboot all day long? Whenever I set up a new system I install all of the updates, drivers and software that are needed on that system. I then create an image of its current, freshly installed state. In the future if my hard drive crashes, my installation becomes corrupt or I simply want to start over with a fresh installation I can very easily. It is much nicer than starting over with a fresh install of an outdated copy of Windows or having to deal with the CRAPware that comes pre-loaded with most consumer desktops and notebooks.
For a few years I was using BartPE with a plugin called SelfImage. It worked tremendously well. The BartPE CD I created must have been trashed when I was in the process of moving. Otherwise, that is probably what I would still be using and I wouldn’t have a reason for writing now. I did try to create a new copy of BartPE but had trouble finding the correct copy of the SelfImage plugin. Frustrated, I started looking for something else. I tried several live Linux distributions that were designed to create and restore drive images. I also tried a couple of free Windows programs. None of them were working. Finally, I came across Redo Backup. I have to tell you that I am VERY excited about this software. It does what a professional grade cloning tool should do, for free! If they were to charge for this application it would be worth every single penny! Though, I hope they don’t because I’m sure it would be expensive!
The feature that I am most excited about is the ability to save and restore images to an FTP server or SMB share. It’s very useful if the machine you are imaging only has one hard drive. It would also be useful in a corporate or educational environment where many machines need to be imaged. I have to tell you that while I did manage to use this feature successfully, I did have problems with it. Many times the process would lock up and the only way to start over was to reboot the machine. Sometimes the screen would go blank only showing the cursor. Like I said, I did manage to successfully backup and restore an image via FTP. But only after many restarts was I successful. The problem could be that the machine I was backing up and restoring was a virtual machine. It could also be a bad connection between the desktop I was running the virtual machine on and the desktop I use as a server.
While I did have issues using the network backup and restore feature; I was completely successful in backing up a hard drive to a secondary internal and external hard drive and restoring the image back to the main hard drive.
In addition to drive imaging you can use Redo Backup to: manage your partitions, use Firefox to download drivers (or just surf the web), synchronize files, recover deleted files, reset your hard drive to factory condition, mount internal or external drives to manage files. You can do all of that and more with software that can be run from an external 256 MB flash drive.
If you’re looking for free drive cloning software, look no further. I have tried them all and I promise you, this is THE ONE to keep in your toolbox!
In the previous blog entry I wrote about Aqua Connect Terminal Server for Mac OS X. While I think it’s a great application for an organization that can afford to implement it, I cannot. I’m sure there are others out there wanting to implement terminal server functionality but can’t afford to pay for a proprietary product either. If you are one of those people, I have great news for you! You can do it right now, for free! All it will take is a Mac with OS 9 or later (I am running OS 10.4.11), Vine Server, a little time and maybe a few groans here and there. But hopefully, this tutorial will get you up and running without going through the moans and groans that I did! Let’s get started.
User account creation and fast user switching
The first task that we’ll take care of is setting up users. I am using a fresh installation of Tiger but you may not be. The first user that I would recommend setting up is an Administrator account.
This is simply an account named “Administrator” with administrator privileges. This is an optional step but I find that it lessens the confusion of system administration. It also gives you an account that you can use to login to the machine you are setting this up on without disturbing a session of another user or your own.
Once you have multiple users set up you need to enable fast user switching. Either click on the System Preferences icon in the dock or from the desktop click on the Apple icon and then System Preferences. Once the preferences panel has opened go to Accounts. Look for a button labeled “Login Options” and click on it. If you cannot click on the button you’ll need to un-lock the system for changes by clicking on the lock at the bottom of the panel. Once there you’ll want to make sure that “Automatically log in as:” is unchecked. Under “Display login window as” I would recommend selecting “Name and password.” This way if someone happens to connect to your system through the network they will not see a list of your user accounts, which will give them half of the information they need to gain access to your system. The very last option is a definite necessity, check the box beside “Enable fast user switching.” The “View as” option is your own personal preference but I personally like the icon since it doesn’t take up so much of the title bar.
System VNC Server, Accept SSH connections and Firewall Configuration
Vine Server does have a system server but I do not recommend using it because it interferes with the functionality that we are trying to achieve. Instead, we will use the system VNC server. To enable it stay in System Preferences.
Click on Show All at the top to return to the main panel. From there click on Sharing. Click on Apple Remote Desktop. The service will start and you’ll need to assign a password in the section “VNC viewers may control screen with password.” You do not have to configure each user account with permissions. The permissions at the top of this screen are for Apple Remote Desktop software connections only.
If you are going to want your users to connect using SSH (great for security) you’ll want to enable the Remote Login service in the Sharing panel as well.
Next we’ll configure the firewall so your users can connect remotely. From the Sharing panel click on Firewall. Make sure that “Apple Remote Desktop” and “Remote Login – SSH” are checked. They should already be enabled. If not, simply select the check box beside them. Next, we need to allow connections into Vine Server (which we will install next). Click on New. Choose Other from Port Name. In the TCP Port Numbers field enter: 5800-5809. In the UPD Port Number enter: 5800. In the Description enter: “Vine VNC Server”. You can now close system preferences.
Install Vine VNC Server
Next you’ll want to login to your Administrator account (again, this is just a personal preference) and install Vine Server.
Configure user accounts
After you have installed Vine Server log out of the Administrator account and log into one of the other user accounts that you created. Inside of each user account do the following: Launch Vine Server from the Applications directory. You’ll be asked to either enter a password or choose none (no password required). I would recommend using the same password that is assigned to that user account. Now, to make sure that Vine launches at log in. Right click on the Vine VNC icon in the dock and select “Keep In Dock”. Right click on the icon again and select “Open at Login”.
We’ll need to make some changes to the Vine Server. From the toolbar click on Vine Server >> Preferences. The first thing you will enter is a display name for the connection. I like to use “username on machinename.” This is for organizational purposes so whenever I connect to the server from a remote machine multiple times I will know which account I am in.
We now need to configure the port. Since we’re also running the system VNC server we cannot use the default ports. This is why I had you to add those ports in the firewall. Otherwise, we could have used the standard VNC option in the drop down menu. You can use port 5800 for this first account but I prefer to use port 5801 for the first user account, 5802 for the second, 5803 for the third and so on. Again, it’s a personal, organizational preference. Before you continue you can also choose whether you want to require users to connect via SSH before they can make a VNC connection. Generally, on a local network I don’t require users to connect via SSH. If a user was connecting remotely, I would.
Let’s switch to the Device tab. Since this machine will be used by multiple users we want to make sure that it will not go to sleep. We also want to make sure that the screen saver is not running. Running a screen saver over VNC will make everything on your network extremely slow. Make sure those check boxes are not checked.
In the Sharing tab, I select “Always allow multiple VNC connections.”
Lastly, make sure that “Stop server on a fast user switch” is unchecked. Otherwise, when you log out you won’t be able to connect again unless you use the system server VNC connection to log in.
Configure all of your users with these settings and reboot the server.
Connect to Apple’s built-in VNC Server
To connect to the system VNC server you’ll need a VNC Viewer. For Windows I recommend TightVNC Viewer. If you’re using Linux use Vinagre or TightVNC. If you’re using a Mac you can use Chicken of the VNC. Testplant has a VNC viewer called Vine Viewer that you can purchase for added functionality.
Once you have chosen a VNC viewer, open it and enter the IP address of the Mac you are setting up as a terminal server and connect. You should be asked to enter the password you entered in the Apple Remote Desktop settings. Enter the password and you should then see the log in screen.
Now all you have to do is log in to each user account so that each account has Vine Server running in it and return to the log in screen using fast user switching. Make sure that you don’t log out or you won’t be able to connect to the VNC server that is running inside of each user account.
After you have finished starting up Vine server in each user account and have returned to the log in screen you can disconnect from the system server.
Connect to user account Vine servers
To connect to the user VNC servers the only change you will make in your connection process is the IP address in the VNC viewer. This time you will enter the IP address of the server followed by a colon and a port number. Example: 192.168.1.23:5801 – This will connect your VNC viewer to the first user account in which you launched Vine server. You’ll be asked to enter the password that you specified in that user account.
NOTE: The default VNC ports are 5900 but since we are running the system VNC server we had to use a different port range for the user VNC servers. If you were not running the system VNC server and were using the default port range you could simply use 192.168.1.23:1
No, this is not a true terminal server. However, if you need this type of functionality and are not willing to pony up the dough, I think this is a great solution. At least, it’s the only solution I have been able to come up with! I think my next experiment will be to see whether I can achieve better performance with it using a FireWire connection. I’ve got to get the FireWire 6 pin to 6 pin cable first. I’d also like to eventually have a dumb terminal connecting to the server to display the Mac OS X desktop.
A few years ago I fell in love with Windows Terminal Services Server. Then I learned about the Linux Terminal Server Project (LTSP) and fell in love with it even more because I could bring old computers to life by booting them over the network with a brand new, full-featured, modern operating system. I love the idea of terminal computing because it gives you the ability to connect from any workstation and access all of your applications and data from each workstation you connect from. Businesses, schools and organizations can implement terminal computing as a way to give more users access to a computer without having to purchase a complete computer workstation for each user.
Since setting up a Windows and Linux terminal server it has been a dream of mine to get a terminal server up and running on Mac OS X. It’s a topic that I will occasionally do a Google Search for to see if there are any new projects trying to accomplish this. A couple of weeks ago I was doing a search on this topic and found two software vendors that offered a solution. I decided to tryout Aqua Connect because it would run on my iBook G3. Yes, ancient technology but it still works and I use what I’ve got!
Taking control of a remote Mac is already possible with VNC server software and of course Apple Remote Desktop. However, with a VNC server and Apple Remote Desktop only one user can use the system at a time. That is where a terminal server comes into play. Multiple users can connect to the terminal server at the same time from their workstation and use the computer they are connected to just like they were sitting right in front of it. Each user can use the applications that they need to without disturbing other users.
Once I found Aqua Connect I requested a free trial and about a day later I received the download link and a serial number. I downloaded the software and installed it. The software is extremely simple to install. If you can install applications on OS X, you can install Aqua Connect. Installing LTSP is much more complicated so I was pleasantly surprised. Once you get the server started, users added and a hole added in your firewall so the software can pass through it; you can connect from any computer on your network, using any VNC server client software (or a thin client that supports VNC connections). It’s that easy. Seriously? Yup!
A couple of cool features in the Aqua Connect preference pane are the ability to control priority for each connecting client and the ability to set the default resolution of the connecting clients.
As I mentioned above I was testing Aqua Connect on an iBook G3 which has Mac OS X 10.4 installed on it. Aqua Connect is designed to work best on Mac OS X Server and of course a computer with more resources. There are two versions of the software. One for OS X 10.4 Tiger and one for OS X 10.5 Leopard. The Leopard version has more features and unfortunately, I am unable to tell you about those as of this time. If in the future I am able to test the Leopard version I will update this article with updated information. I mention all of that so you can keep that in mind as you read the rest of this entry.
To connect to the server you can use any VNC client software (TightVNC Viewer, RealVNC, Chicken of the VNC, etc). The problem with this is that VNC is terrible for performance. For quick maintenance on a system it is okay but I don’t think anyone would want to browse the Internet or use many applications at a time due to the slow screen re-drawing time. Fortunately, the Leopard version of Aqua Connect supports connecting via RDP (remote desktop protocol) clients which should make the OS X terminal server experience a much more pleasant one.
There were a couple of quirks that I encountered while testing Aqua Connect. The first is console lockups. After connecting and logging off multiple clients I would try to login to the server (the iBook G3) but could not enter any login credentials. It looked as though there was a remote login being displayed over the real login screen. I don’t know if this was actually the case or not but the display had a much lower resolution than it normally does. I could not interact with the console and had to reboot when this happened. The second quirk was that I would sometimes be unable to login to the terminal server from a remote client without rebooting the server first. I just assumed that these quirks were due to it being installed on the client version of Tiger instead of the server version.
I did not obtain a direct quote from Aqua Connect for pricing but I did find information regarding a “Green Campaign” that they had earlier this year in which 20 concurrent connections of Aqua Connect were given away. The retail price of the 20 concurrent connections was $7,980. So, approximately $400 for each client license. While that is out of my price range it could be very beneficial for a business that is trying to save money on energy costs. (Out of curiosity I do wonder how much the cost of the license would drop if they had not licensed RDP technology from Microsoft.)
The alternative to Aqua Connect is iRAPP Terminal Server. It looks like a really great solution as well but unfortunately, it only runs on Intel Macs so I am unable to test it. They are more up-front about their pricing, which I like. Their pricing for 20 users is $5256.00. One user is $262.80 (at the time of this writing).
Both of these options are currently out of my budget, but, they’re definitely interesting projects to look at if you’re interested in terminal computing. I will be sticking with a simple VNC server since it accommodates my needs nicely.
