A window opens up that says "TN Quick-Connect" and asks you a number of questions. You can exit the emulator by pressing Control-Q or by clicking on "Exit" from the File menu. Double-click TN again. Note that if you hadn't closed the previous window, this would start up a second TN session. This is useful, because it's sometimes nice to have two or more sessions open at once.

This time, after filling in the host name, type a device name in the next box. Only some of TN's options can be set using the Quick-Connect dialog. Most of the options are set using the a "command-line" or "profile" option, which is explained later in this document. Here is a list of the options you can set on the Quick-Connect screen, and what they do:. It can be a "domain name" such as AS COM or it can be an IP address such as Just separate the host name from the port number with a colon.

For example, to connect using port , I might specify:. You can also add a "stream type" identifier to the beginning of the host name. For example, if I wanted to play back a debugging trace file, I could specify:. Many companies will generate their own certificates, instead of paying for the services of an official certificate authority. If the "Verify Server" option is checked, these certificates won't be allowed, and the connection will fail.

You can specify your own certificate authorities as being trusted by TN, if you wish to use this option in that scenario. See the section entitled "SSL Options" for more information. When this option is set, text is copied to the Windows clipboard immediately when you highlight it with the mouse.

The text can be pasted to the window by right-clicking in it. If this option is not enabled, you'll need to click the Copy option from the Edit menu, or press Ctrl-C to copy text to the clipboard, and click the Paste option from the Edit menu or press Ctrl-V to paste the text. Here is a list of some of the common character maps:. Here you can select whether you want a terminal that's capable of only 24x80 mode 24 rows by 80 columns or if it's capable of both 24x80 and 27x If you select 24x80, tn will emulate an IBM terminal.

One of the most useful features of TN is that you can set all of your options using the command-line. Unlike the Quick-Connect dialog, this allows you to specify any of TN's options. Launch TN by typing the tn command, followed by the name of the host you want to connect to. For example:. Notice that when you do it this way, you don't get the Quick-Connect dialog. So how do you specify a device name? You can specify different stream types and ports in your hostname here, too.

For example, to connect to port using an SSL-encrypted stream, you can type:. Its very important that there be no spaces in the middle of a command-line argument. So, typing env. If you do need to put spaces in your options, you should wrap the entire option in quotes.

For example, this is perfectly legal:. You can use command-line mode in conjunction with the Quick-Connect dialog if you want to specify some options that cannot be given with Quick-Connect. For example, you might type:. Because I did not give a host, above, the Quick-Connect dialog will appear to ask me which host to connect to. In addition to that, however, it will use the Courier New font, and it will draw rule lines to indicate where my cursor is. There are many more options available from the command-line in tn Now, lets suppose that you've gotten tired of typing all of the options that you want to use each time that you start a new session.

You can set all of your command-line options in a Windows Shortcut. When you run the short cut, they'll be used automatically. Open up your My Computer icon, and navigate to the directory where you installed TN Close the My Computer window, and right-click your desktop. Choose "Paste Shortcut". Right click the new shortcut, and select "Rename". Rename it to something easy to remember. I called mine "DSP51". On the line that says "Target:", add the options that you'd like to use. For example, I'm setting my Target to look like this:.

No more typing all of those options! Sometimes its useful, especially when you have a lot of settings to manage, to keep your tn settings in a file, instead of typing them all into a command-line or shortcut. Just like you did when you tried out the command-line options, Switch to the directory where you installed the TN software. Set all of your TN options in this file. For example, if you wanted to create a display called FRED1 which connects to an as called iseries. Now that you've created this, you can utilize those settings just by typing: tn profile1.

Be careful of capitalization. You can set any of tn's settings in the tnrc file. Here's a more sophisticated example:. See, I wasn't kidding when I said that would be more sophisticated! This copy of tnrc contains 3 different profiles called profile1, profile2 and printer respectively. Tip: You can use profiles as arguments when you create a Windows shortcut as well!

For example, set the "Target:" in the shortcut properties to:. First, a quick explanation, since Windows users are probably wondering what the name "lpd" means. On Unix systems, the print spooler is called "lpd", which stands for "Line Printer Daemon".

When printer support was added to TN, they cleverly decided to call the printer program "lpd" line printer daemon. When I converted the code so that lpd would run on Windows systems, I kept the name. There is very little reason to interact with lpd while it's running. As I'm writing this document, lpd does not have a "Quick-Connect" dialog like tn does. You have to configure it using profiles or command-line arguments. With this simple of a set up, every document will just be a plain text representation.

In this example, we will do a more real-world configuration of lpd. We will place all of these settings in a profile in our tnrc file, and create a shortcut for the printer. If you don't know how to do this, see the previous section in this document. If you don't already have one, create it now. Add a new profile onto the end. For our example, we'll create an entry for Hewlett Packard LaserJet 4 printer.

So, I'm going to call the profile "hp". This is the correct value for the United States, as well as several other countries. So that we don't need to open up an MS-DOS prompt each time we want to start lpd, we'll create a shortcut on our desktop which will start it when we double-click it.

Double click the "My Computer" icon and navigate to the directory where you installed TN Choose "Paste Shortcut. Right-click the new shortcut and choose "rename". Change the name of the short cut to "PRT04" or another name that appeals to you. Switch to the "Shortcut" tab, and at the end of the text in the "Target:" box, add profile name of "hp". In addition to providing data encryption, SSL also provides authentication.

By authentication, I mean that one computer is able to tell that the other computer is actually who it claims to be, and not an imposter. For more details, I recommend looking at the documentation that came with your server. At the time of this writing, IBM supplies the C. If you're given a choice, you'll want to install AC3, as it has the best cryptography. Click "System Certificates". Select "Work With Secure Applications".

It should tell you that your telnet server has your system certificate assigned to it. IF not, you can assign it here. If it is already running, you'll have to end it, and start it again.

Now, verify that your SSL-enabled Telnet server is running. Press F14 to display the port numbers. Look for a server that's in "Listen" state on port This is the SSL telnet server. For example, type:. However, no authentication is being done! It is a good idea when using SSL to verify the certificate that your telnet-ssl server is sending to tn This ensures that you are communicating with the server that you think you are, and that your connection is not being "hijacked" by a 3rd party.

Highlight the certificate that is displayed with your mouse. Then choose "Copy" from your web browser's Edit menu. Open a utility such as Notepad and paste the certificate into it. Here's an example profile:. If you set this up correctly, you can restrict your system to people who you've specifically given certificates to.

Explaining how to configure the server for this is beyond the scope of this document. However, once the server has been configured this way, you'll need to know how to tell TN to use a certificate assigned by your server. In order to follow these steps, you'll need the openssl.

If you built tn from source, you built it when you compiled OpenSSL. Connect to the Admin server with a web browser I used Netscape Navigator 4. Netscape brings up the "New Certificate Authority" wizard. Follow the prompts, until you can finally click "Finish". Netscape brings up the "Generate A Private Key" wizard. Follow the prompts. The password you assign it is only temporary, but you should assign it one.

Maybe "tn" is a good password. After filling out your password, and waiting a second or two, you should come to a screen that says "User Certificate Created Successfully". In our test case, we selected key length Have seen reports, where if using Windows 10, the certicate size should be We must now assign the new certificate to the Telnet Server. Go back to the main menu, and select System Certificates. Select Work with system certificate Select the Certificate to use.

Click Assign new certificate. If it says No, there is something wrong. Actually the port text is telnet-ssl, but it is truncated in the default display. Please use the IBM support function for such issues. What is a company license? With a company license it is possible to install the product on an unlimited number of work-stations.
