5.1.12 Creating and Modifying Terminal Services

Terminal services allow client-based terminal emulator programs to connect to the UNIX host. For many clients, you can simply use the built-in TCP/IP protocol and a vendor-provided--or third-party--telnet program. TAS LM-NT-OS/2 terminal services provide the same capability using NetBIOS--either TCP/IP or NetBEUI--as a transport. To connect to TAS LM-NT-OS/2 terminal services, you need a terminal emulator that supports NetBIOS, such as Kermit. Usually, clients with only NetBEUI available use TAS LM-NT-OS/2 terminal services.

Follow these steps to create or modify a terminal service:

1. Follow these links:

   • LM-NT-OS/2 Realm->Manage Terminal Services

     The List of LM-NT-OS/2 Terminal Service screen appears.

2. From the list, select the terminal service you want to modify, or enter the name of a service you want to create in the text field. The list contains nothing if no terminal services exist.

3. Click Create or Administer. The Administer button does not appear if no terminal services exist.

   If you clicked Create, the Create New LM-NT-OS/2 Terminal Service screen below appears. Go to Step 4.

   If you clicked Administer, the LM-NT-OS/2 Terminal Service servicename screen appears. Click Configuration, or click the appropriate link from the following, then click OK on the subsequent screen: Accept Service Connections, Reject Service Connections, Status, Start Service, Shutdown Service. If you click Configuration, the Update LM-NT-OS/2 Terminal Service servicename screen, same as the Create New LM-NT-OS/2 Terminal Service screen below, appears. Go to Step 4.

   

4. Enter or select values for the following attributes, as needed:

   • LM-NT-OS/2 Terminal Service Name -- The terminal service. If you clicked Administer and Configuration, this attribute does not appear.

   • Service description -- The description used within TAS for the service. It consists of an arbitrary line of text.

   • Transport -- The protocol stacks over which you may offer the service. The LM-NT-OS/2 realm can use tcpip (TCP/IP) and tnnbu (TotalNET NetBIOS-over-NetBEUI).

   • Start this terminal service? -- The option to start this terminal service when you click Submit. If you clicked Administer and Configuration, this attribute does not appear.

5. Click Submit.

   The Create New LM-NT-OS/2 Terminal Service servicename screen or the Update LM-NT-OS/2 Terminal Service servicename screen appears.

6. Click OK.

   To administer terminal services from the UNIX command line, use the tnservice command.
