Chapter 1 Getting Started 893-386-B 1- 1 The Model 3395/3395A Terminal Server is a combination of hardware and software that links users at serial devices, such as terminals, to resources on both local area networks (LANs) and wide area networks (WANs). These resources include a variety of hosts, workstations, and printers, as well as other SynOpti[...]

Getting Started 1- 2 893-386-B The user in Figure 1-1 has made a connection to the UNIX host on the LAN through the terminal server. He can now read databases, send mail, and run applications on this host. He can also connect to the VAX host, the IBM host, or a serial device on the other terminal server. Expanding the Network with the Terminal Serv[...]

Getting Started 893-386-B 1- 3 The remaining sections of this chapter explain how you can use the terminal server in a network such as this one. These sections include the following topics: • Using the terminal server • Logging on to a terminal server port • Managing sessions • If you make a mistake • Privilege levels • Summary Using th[...]

Getting Started 1- 4 893-386-B Logging On to a Terminal Server Port If your terminal is connected directly to a terminal server port, press the <Return> key until one of the following prompts appears on the screen. If your terminal is connected to a host on the terminal server network, log off of the host, or suspend your current session by p[...]

Getting Started 893-386-B 1- 5 Managing Sessions The connection between a terminal server port and a device on the network is called a session . You can establish a session with a LAT service, a Telnet host, an IBM host, or another terminal server after you log in to the terminal server port. The Model 3395/3395A Terminal Server allows you to open [...]

Getting Started 1- 6 893-386-B Suspending a Session When you suspend a session, you recall the Model 3395/3395A command interface without terminating the connection to the remote resource. Later, you can reopen the session and continue with your work. To suspend a session, press the Break key or the local switch character during the session. (A loc[...]

Getting Started 893-386-B 1- 7 To switch from session 2 at a LAT service to session 1 at FINANCE.SUN.COM, you could use a sequence like this with the RESUME command, beginning at the LAT service: $ $ <BREAK> FINANCE.SUN.COM session 1 resumed Disconnecting From a Session You can disconnect from a session in two ways. If you are currently logge[...]

Getting Started 1- 8 893-386-B Using UNIX Aliases for Terminal Server Commands The Model 3395 Terminal Server software provides several UNIX equivalents, or aliases, for Model 3395/3395A Terminal Server commands. If you work in a UNIX environment, you may want to use these aliases because they will be more familiar to you than the Model 3395/3395A [...]

Getting Started 893-386-B 1- 9 Summary The Model 3395/3395A Terminal Server provides you with access to many resources on the network that might be unavailable to you otherwise. To use the terminal server, you log on to a terminal server port and establish sessions with hosts or other terminal server ports. You can suspend sessions and establish ne[...]

Chapter 2 The User Interface 893-386-B 2- 1 This chapter describes how to use the terminal server command interface and the terminal server menu interface. It includes these topics: • Entering commands • Editing the command line • Assigning session management functions to keyboard characters • Session switching characters • Telnet session[...]

The User Interface 2- 2 893-386-B Users at Nonprivileged and Privileged ports can change the defaults for the editing characters with the SET PORT command, so the characters on your port may not have the same functions as the ones shown in Table 2-1. At most terminals, you can use the SHOW|LIST PORTS ALTERNATE CHARACTERISTICS command to check the c[...]

The User Interface 893-386-B 2- 3 The following example shows how to use the command line recall and editing features. Suppose that you enter the following command, which contains a typographical error: TS3395> shw port characteristics The terminal server would not accept the command because you spelled SHOW incorrectly. Instead of retyping the [...]

The User Interface 2- 4 893-386-B The user at this port can now use <CTRL><L> to suspend an active session. Because this is a SET command, it takes effect immediately, but remains in effect only until you log off of the port. Assigning a Local Switch Character If your terminal or workstation does not have a Break key, you must define a [...]

The User Interface 893-386-B 2- 5 Telnet Session Management Characters Telnet session management characters provide command line editing and process management during a Telnet session. Table 2-3 lists the keywords you use with the SET PORT commands to assign Telnet session management functions to control characters Table 2-3. Telnet session functio[...]

The User Interface 2- 6 893-386-B Using the Terminal Server Menu The Model 3395/3395A Terminal Server software running on your terminal server may have a menu interface rather than a command interface. You will know this if a menu appears on your screen rather than the TS3395> prompt when you log on to the terminal server port. You see a menu si[...]

Chapter 3 Using Model 3395/3395A Terminal Server Commands 893-386-B 3- 1 This chapter describes the commands you can use at Secure ports.
