Time to get on trend. Best practices to increase the speed for Next. Thanks to Mark Phinney at cflsb. Unfortunately, it looks like the Microsoft stack limits the packet size to bytes so it would take some effort to make it work efficiently. The only real downsides here are 1 it uses more memory, and 2 it is more complicated, but you really can't beat this solution if this is what you need. You can download his VIrtual PC floppy image file here , and then boot it up on your machine and take a look to see how he did it and adapt it to your configuration.

Also note that you need to have NetBUI enabled on the server machine. While certainly possible, it would take some effort to make it work efficiently. I'd actually love to start a project to have TINY talk directly to the network card, probably using a Crynwr packet driver. This would reduce the amount of memory needed on a TINY host and with one less piece of software things would generally be simpler to set up. Let me know if you have a good reason to need this.

For example, to load the TINY client with both the sample translation files, you'd type something like There are a huge number of graphics modes available on the various brands and models of graphics cards and there is no standardized way to access these modes in DOS, so TINY only includes support for some of the most popular modes.

First, make sure you are using the "extended" version of the TINY host that includes graphics support. If you try to view a graphics screen with the standard version of the host, you'll always get the "mode unsupported" message.

If you using the "extended" host versions and are still seeing this message, then your application is using a mode that TINY does not know about. Try to configure your application to use one of the modes that TINY does support. If you really need to use a specific application with TINY and that application can only use a graphics mode that TINY does not support and you'd be willing to pay for the work to add support for that mode to TINY, get in touch with me at the email address below.

You can use optional command line parameters to specify what UDP port the host should listen on and what port the TINY client should call out to. By default, both use port hex. Note that it is even possible to load multiple copies of the host listening on different ports on the same machine, although this uses up lots of memory.

My goals were to make it small tiny? Since it runs on the non-DOS side of the connection, I assume this machine will be pretty modern and fast. Make sure you are using the very latest version of the Java runtime - the most recent once is better than the previous one. I'm not sure why, but it is cleverly hidden on the Sun website here Using longer delays and thus lower refresh rates will reduce the CPU load on both the host and the client and will also reduce the bandwidth requirements. The downside to lower refresh rates is that you will see the screen update less frequently.

This can be annoying if you are using an interactive application, especially when you are trying to type quickly. On the flip side, specifying too fast a refresh rate too low of a delay can cause annoying problems as well. If you set a rate that generates more data than your network connection can handle, packets will start to get dropped.

Once this happens, performance degrades very rapidly and unpredictably. This once happened to me and it took a while to figure out what was wrong. I had specified a refresh rate that seemed to work fine and gave me snappy response when I was typing on the remote machine, but every once in a while everything would grind to a halt and my keystrokes would start taking several seconds to show up.

It turned out that someone else was occasionally TINYing onto a different machine over the same DSL link and between the two of us we were saturating the connection. We both slightly reduced our refresh rates and everything worked great. The default refresh rate is ms, which translates to 10 refreshes per second. This is fine for a local Ethernet network connection, but will probably not work well over the internet.

This leaves enough bandwidth available that two people can TINY across the connection at the same time without saturating our internet connection. Ultimately the correct setting for a given installation will depend on the application and the connection, so you'll probably need to try several different values to find what works best for you. Start with a high delay and work your way up to until you find a delay that is not annoying to use and doesn't saturate the connection.

Turn on the TINY status screen on the client and watch the dropped packet counters. A few occasional dropped packets are normal, but if you start seeing the counters incrementing regularly, you'll probably need to throttle back and use a higher delay. Keep in mind that other things going on over your network connection or the one at the remote machine can use bandwidth too, so you are more like to get see dropped packets if someone in your house starts downloading a Justin Timberlake video on YouTube.

In this mode, the TINY host will write two letters to the upper-left corner of the text screen whenever a packet is received. This can be useful in debugging problems where you are not getting any response on the client.

The letter in the first position simply cycles each time any request packet is received by the host. The second letter lets you know how the received packet was processed. Here are the possible codes In Windows, you can use a batch file to ask for a password and then launch TINY with the password as a parameter. Try something like There are four sample fonts in that collection that I've made just to give you an idea of what is possible Note that if you use a font on the client that is a different height in pixels than the font on the host, your cursor might look different on the client than on the host.

For example, if the host machine is using the standard VGA font that is 16 pixels high, but you are loading the "small. Q: Sometimes when I manually pick a screen mode, I see "Received Corrupted Frame" on the Java console and the client screen stops updating. Despite the ". If you make a particularly useful one, please email it to me so I can share it with everyone else. I also have a tool that I wrote to dump the font table on a VGA card into a TF file, but it would take me longer to explain how to do this than it is worth.

If you really need to dump a special font, let me know and I'll walk you though it. I also have a tool that can convert some TrueType fonts into TF files. If you request an invalid mode say, Hercules Page 1 on a machine that doesn't have a Hercules card installed , the host machine may try to send packets based on memory that doesn't even exist on the host machine.

The contents of the packets are typically all 1 bits, so the TINY client can't find the appropriate data fields in the packet. This does not cause any harm or problems for either the host or client machines, and you can fix it by just selecting a mode that is supported on the host machine. The latest version of TINY introduced a new protocol that is much more efficient.

If you can seamlessly connect to a host running the new version with an old client, but to connect to a host running the old version using the new client you must select "Auto-Legacy" under screen modes. You can easily do this from the TINY client command line or using the pop-up menus. Or better, upgrade your host to the new version too! You can find some partially inaccurate documentation here.

Here is an example of an FTP script file called script. You might also want to check out JoshFTP here. It is like the Novell FTP client, except that it doesn't crash all the time. You can download it directly from Novell here. You can also download a really nice Novell DOS boot disk here. ZIP file above also includes all the Novell files you'll need besides the driver for your network card.

The specifies the screen scaling factor that the TINY client should use at startup. Higher values make for a larger and blockier client window. This specifies which screen mode TINY should use on start-up. You typically would want to let TINY auto-detect this, but you might want to specify it explicitly in cases where TINY can't accurately auto-detect which mode to use. One example is if you have a two monitor set up on the host, TINY can't know which monitor you want to see so , or if the host is in a Hercules Graphics mode there is no reliable way to detect Hercules modes.

Q: Can the size of the client window be changed dynamically by the user when connected. If you click inside the TINY client window when connected, you can use the "Scale Screen" submenu to change the size of the window. Make sure your config. You'll need to load a suitable Novell Client32 driver for your card. These drivers always end with a ". LAN" extension. You can find drivers for most common network cards on the Novell website.

You can also usually get the driver file from the card's manufacturer. If you can't find the right driver anywhere, consider just buying a new well supported card since they are so cheap now. This is the line that loads the network card driver for an Intel Pro Ethernet B network card. Copy your driver into this directory and then change that line to reflect your card and everything should work.

Note that some cards need extra parameters at the end of the line. These are different for every card, so you'll have to figure it out yourself. Try looking at the card's documentation, or just experimenting. Sometimes the driver will give a useful error message when you use the wrong parameters and that message can help you guess what the right ones might be. Q: My card doesn't have a bit Novell driver ends in. Am I screwed?

You can also use bit Novell ODI drivers, you just need to load some "shim" drivers that make it possible for the bit stack to talk to them. The only downsides are slightly lower performance and slight higher conventional memory use compared to a real bit driver. And it can be a pain to get it to actually work sometimes. It is usually easier to get a new card that does have Novell 32 bit drivers. Here is some documentation on loading 16 bit drivers from Novell. Q: What does the "Send keyboard scancode" function do?

COM use tricks to access the keyboard in non-standard ways. Because of this, these programs can not see keys that are stuffed into the keyboard buffer by programs like TINY. Thanks to a an amazingly useful text on PC keyboards , I've added the ability for TINY to put keyboard scancodes directly into the keyboard controller chip. This technique is good enough to fool every program I've ever tried into thinking the keys were really pressed on the local keyboard.

So why not use this technique by default? Well, scancodes are messy. There are lots of different types of keyboards with different keys in different places making different scan codes. Normally the PC BIOS takes care of all this so you just push the "A" key and see an "A" pop up on the screen, but when faking keys into the controller you need to do a lot of this work yourself. The basic idea is that every actual key on a keyboard is a little switch.

When you push the key, the keyboard sends a scancode to the keyboard controller in the computer. When you let go of a key, the keyboard sends a different code. You can use the "Send keyboard scancode" to directly put these codes into the control as if they came from the keyboard itself and trick the computer into thinking you pushed or let go of any key on the keyboard in an order Think Alt, scroll lock, even the power button.

To send a key, you need to know the "make" code the code sent with the key is pressed and the "break" code the code sent when the key is released. Here is a table of all the make and break codes for a standard keyboard taken from the above website For example, if you wanted to type the letter "J" on the host, you'd first look up the codes from the above table and then type "24 A4" into the "Send scancode" window on TINY.

The "24" pushes the "J" key on the keyboard and the "A4" lets go. So, let's say you started dos EDIT by mistake and now you can not exit because it is not recognizing your keypresses. This would push "Alt", then push and release "F", then let go of the "Alt", then push and release "X", thus quitting the program. If you want to know the scancode for some fancy keyboard or a foreign keyboard, refer to this guide to every keyboard scancode imaginable.

The only difference is that the "extended" version of TINY supports graphics modes on the host. This takes significantly more memory, so if you only need text modes you should probably use the standard version. If you load the standard version of TINY and then switch into a graphics mode, you'll see a "mode not supported" message in the client. Note that I have not included a graphics version that runs on the FTP stack inside the distribution.

Let me know if you need this and I'll compile it for you. Q: Why are the colors all messed up when I run xx graphics mode programs? By default, TINY will automatically send xx graphics screens in compressed nibble format. This mode uses only half as much bandwidth as sending the full color data, but the costs is that you only get half as much color information. DOS graphics applications tend to only use the first 16 colors anyway, so typically this is ok.

If you are using an x application that really uses all the colors and you want to see them all, you can manually select this mode on the client by clicking on "Host Screen Mode" and selecting the non-compacted x mode. Note that this will be MUCH slower than compacted mode. Also note that when you quit out of the graphics application, you'll have to go back into the "Host Screen Mode" menu and re-select "Auto" to see the text screen again. Q: What is are the "sliced text" modes for? These modes divide up text screens into multipule packets so that no packet is bigger than bytes.

So, for example, if you pick "Sliced Text 80x25" mode, it will take 5 packets each with about data bytes to see a full screen update. Some reasons why you might want to send lots of little packets rather than one big one There is a bug in your network card driver that doesn't let it send giant UDP packets I'm talking to you, Realtek.

Each little packet causes a shorter pause for the running forground program than one big one would. There is some firewall or router between your TINY client and host that can't deal with giant packets. Becuase the packets are smaller, you can probably send them more quickly without causing more network problems.

TINY will never automatically select a "sliced text" mode. There is an application from TeamPhone that seems to need this interrupt to tell it to wake up and read any pending keys. If you have an application that doesn't seem to want to read the keys from TINY, you can try this option, but in general you shouldn't need it. Maybe, but it will be slow. Maybe try using one of the sliced text modes. If you do not have an internet connection to the host, maybe consider trying my WHOST program instead.

WHOST runs great over slow serial links like dial-up modems.

This project is now dead. TightVNC is a free remote control software package. With TightVNC, you can see the desktop of a remote machine and control it with your local mouse and keyboard. It is a fast and flexible VNC client. The extension supports both RFB clients and servers.

TclRFB will allow the creation of light-weight, scripted remote interfaces. It is based on orignal vncviewer code for XWindows. It was designed to work efficiently with large number of clients. It requires Silverlight 4. Letters they type are printed to your screen. It also supports VeNCrypt encryption. The Unix viewer has many new features. We have large collection of open source products. Most other vnc servers will spawn an entirely new graphical session.

This is for remote support, where I want the user and the supporter to share the same session. This avoids the annoying hard coding of gdm, lightdm, xdm or specific users. The following should work for any distro that uses systemd, just the apt bits are Debian specific. Generate the password and store it under etc so no users can change this password, only root. You can do this under your users home so that its not managed by root. And add the following, making any changes you want to the x11vnc ExecStart See the man page for explanations of the switches.

Now enable the above, start it and verify its running and listening properly systemctl enable x11vnc systemctl start x11vnc netstat -pat tcp 0 0 0. Now that the server is all setup lets move onto the client apt-get install tigervnc-viewer vncviewer [remote host ip or hostname]. It listens on any interface so you can bring up the network any time and it will be listening and ready for connections. By far the best explanation and working guide.
