Telnet server overview
The Telnet server is a gateway for Telnet customers. When running the Microsoft Telnet server on your computer, users can connect to the Telnet server from the remote computer using the Telnet client. When the Telnet client is connected to the Telnet server, the system is required to enter the username and password. By default, only the legal usernames and passwords on the local server can log in to the server.
After logging in, the user will receive a command prompt, and then the user can be used like the command prompt window in the local open. However, by default users cannot use applications with desktop interactions.
Telnet uses the Telnet protocol (Some TCP / IP Protocol Suite) Connect the remote computer via the network.
The Telnet protocol license provides a Telnet server installation protocol license for each Windows 2000 Server installation.
The following table shows the maximum number of connecting Telnet servers at the same time:

TelnetTelNet customers and Telnet servers work together to allow users to communicate with remote computer.
Telnet clients allow users to connect to the remote computer and interact with the computer via the terminal window.
The Telnet server allows Telnet clients to log in to a computer running a Telnet server and run a character mode on the computer. The Telnet server acts as a gateway and can communicate with each other through the gateway Telnet customer. Windows XP also supports up to two Telnet customers at the same time. If you need additional licenses, use the Telnet server for the Microsoft Windows service for UNIX products.
Using Telnet Cameline This section contains information about the following:
1. Authentication 2.Telnet Command 3. Session mode and command mode 4. Manage Telnet 1. Authentication from the command line: You can use the local Windows username and password or domain account information to access the Telnet server.
If the NTLM authentication option is not used, the username and password will be sent to the Telnet server in a clear text.
If you use NTLM authentication, Telnet customers use Windows XP security environments to authenticate, nor is you prompted to provide usernames and passwords. The username and password are encrypted.
If you set the password option to "Change your password when you log in", the user will not be able to log in to the Telnet server using NTLM authentication. To make the login success, the user must log in to the server directly, change the password, and then log in with Telnet.
If you use NTLM authentication to connect to the Telnet server, you will not be able to access other network resources due to this authentication limit. To access network resources through a Telnet session, you need to re-provide the username and password to access the network drive.
2.Telnet Command: Telnet Customer Command Prompt Accept the following command:
Command Description Open uses Open hostname portnumber to create a Telnet connection to the host. Close You can close the existing Telnet connection using the Command Close. Display Using Command Display You can view the current settings of Telnet customers. Command Display can list current operation parameters. If a Telnet session (ie, connected to the Telnet server), press Ctrl } to modify the parameters. This will exit the Telnet session. (To return to a Telnet session, press Enter.) The operating parameters available are as follows:
Will Auth (NTLM Authentication) Wont Auth Will Term Type Wont Term Type Localecho Off Localecho ONQUIT You can exit Telnet. Set Using Commands SET Settings You can set the connection terminal type, open local back, set NTLM authentication, escape characters, and login.
Set NTLM can open NTLM. When using NTLM authentication, the system prompts you to provide the login name and password required to connect from a remote computer.
Set Localecho can open locally. Set Term {ANSI | VT100 | VT52 | VTNT} Sets the appropriate terminal type. If you are running a normal command line application, use the terminal type VT100. If you are running an Advanced command line application like Edit, use the terminal type VTNT.
Escape Character can set the button sequence switched from the session to the command mode. For example, to set Ctrl P to an escape character, type Set Escape, press Ctrl P, and press Enter. Logfile FileName can set files for logging Telnet activity. The log file must be on the local computer. When this option is set, the record is automatically started.
Logging is used to open the log. If you do not set a log file, an error message will appear.
UNSET You can turn off local echo or set up the login name / password prompt verification.
UNSET NLM can close NLM. UNSET Localecho can turn off local back.
Status Use the status command to determine if the Telnet customer has been successfully connected. Ctrl } Press CTRL } to turn from the connected session to the Telnet command prompt. ENTER uses Enter commands to turn from the command prompt to the connected session (if present). ? / HELP print help information. Session mode and command mode Telnet Customer has two working modes: telnet command mode and Telnet session mode. The Telnet command pattern allows the Telnet terminal to open or close to the remote host connection, display the operation parameters, set the terminal option, print state, and exit program.
Once connected to the remote host, Telnet customers enter the Telnet session mode. This is the most common mode. After logging in, the user will receive a session of a command prompt. At this time, the user can use any remote computer-based application, running a Telnet server like directly logging in to the system.
Once connected to the host, you can return from the session mode to the command mode to change the terminal settings. Press CTRL } to go to Telnet command mode from Telnet session mode. Press ENTER to return to the Telnet session mode From the command line management Telnet using the telnet command used in the remote login environment to allow you to communicate with remote computer using the Telnet protocol. Telnet running without parameters allows you to enter the remote login environment. Once a prompt appears, you can manage the computer running a Telnet customer using the remote login command.
