Start Telnet in Windows 7

We all know that Telnet is a protocol used for remote logon. In many cases, this protocol has some vulnerabilities. In many systems, the default status of this protocol is forbidden. In Windows 7, how does one start the Telnet service?

1. hidden reasons

In fact, Telnet cannot be found in the service manager. instead of abandoning Telnet in Windows 7, Telnet is not installed in Windows 7 by default. this is the first time Microsoft has removed default system components from its personal system via Telnet, which is similar to Windows Server 2008. I think Microsoft should do this for security reasons. After all, Telnet data is transmitted in plaintext, and attackers can easily obtain sensitive information through sniffing. based on security considerations, we recommend that you use a more secure and encrypted SSH remote management method.

2. Install Telnet

However, we do not have to discard food for some reason. It is very convenient to Telnet as an individual user. the installation of Telnet in Windows 7 is slightly different from that in Windows Server 2008. You can perform the following operations. click "start"> "Control Panel"> "program", "Find and click" open or close Windows "in programs and functions to go to the Windows function Setting dialog box. find and check "Telnet client" and "Telnet Server", and click "OK" to complete the installation. in addition, we can also install "TFTP client" and "Internet Information Service" through this wizard. (Figure 1)

After the installation is complete, the Telnet service is disabled by default. you also need to run "start" → "run" and enter servcies. msc open the Service Manager. find and double-click the Telnet service item, set the start mode to "Manual" (more secure, enable only when needed), and then "start" this service "OK" to exit. (figure 2)

3. Set Telnet

The seamless integration of Telnet and system firewall in Windows 7 enables custom control and enhances the security of Telnet. choose network and sharing center> windows Firewall> advanced settings to go to the firewall settings window. click "inbound rules" in the left-side pane, find "Telnet Server" in the middle pane, right-click the rule and select "properties" to go to its attribute settings window. click the "General" tab. By default, the firewall allows all Telnet connections. based on security considerations, select "Allow the connection if it is sevure" (only secure connections are allowed), and then you can customize security rules. click the "computer" tab. Under this tab, you can set a computer that authorizes Telnet connection and an exception computer. click the "Scope" tab. Under this tab, you can set local IP addresses and remote IP addresses to control the Telnet connection. click the "user" tab. Under this tab, you can add users who can remotely Telnet. (Figure 3)

4. connection test

To verify whether Telnent settings are valid in Windows 7, Telnet to the Windows 7 host through a Windows Visata host for testing. Run the following command on the Vista command line:

"Telnet 92.161.100": After you press enter, you are prompted to enter the user name (only the jp user is allowed to log on) and password. it indicates that Telnet is successfully installed and our firewall settings take effect. (Figure 4)

Windows 7 Telnet: although the security of Telnet is not very high, the security of Telnet is greatly improved through seamless integration with Windows 7 firewall. in fact, all network-related tools in Windows 7 can be closely integrated with firewalls.
