Port 3389, it is best not to open this port, that is to say, don't open the remote desktop, because hackers will enter your computer through this port and implant Trojans. Now our computer security awareness is getting stronger and stronger, and there are fewer and fewer computers opening 135 port, so hackers hope to catch broilers through this port.
You can modify the remote desktop port through the registry or software. Modifying a remote desktop port requires two steps:
1. Open the registry [HKEY _ local _ machine \ system \ current control set \ control \ terminal server \ WDS \ rdpwd \ TDS \ TCP] and modify the value of the port number on the right. Its default value is 3389, which can be modified to the required port, for example, 3309.
2. Open the registry [HKEY _ Local _ Machine &; Staring at 92; System \ currentcontrol1set \ control \ tennalserver \ winstations \ RDP-TCP], and modify the value of the port number on the right again, and its default value is 3389. Just change it to the desired port, such as 3309.
Refresh the registry after modification, except if there is a firewall. Port filtering has been completed, and the modified port needs to be opened.
Question 2: What ports do I need to open to connect to the remote desktop? Default remote port IP:3389. Of course, port 389 can also be changed to another port for remote use, but it must be IP: 3389.
Question 3: What do remote ports and remote addresses mean? The local port is the port number on your machine.
A remote port is a port that connects to your computer or server.
Personally, I think the port should be used to distribute the data you receive from the Internet.
Online data can accurately find your computer according to your IP, but your computer is not just running a program. How does the computer know which program the data it receives is sent to? It depends on the port number. If a program on your machine wants to communicate with the Internet, it must first apply for a port number from your machine. Similarly, servers on the Internet also run many programs at the same time. In order to allocate data clearly, it must also assign a port number to each program.
Your computer is like a big hotel, and the data on the Internet is like mail. Only the name of the hotel can not accurately deliver the mail to the target, because there are many rooms in the hotel, and the mail should be delivered to the room accurately, with the room number, that is, your port number.
Someone attacked you, as if you couldn't tell from there. Should the firewall be enough?
Question 4: What is the port of remote connection? Its port defaults to 3389. Of course, you can change port 3389 to another port for remote use, but it must be IP:3389.
Question 5: What is the general remote server port? The remote port is generally 3380, but other numbers can be set! I hope it works for you!
Question What port does windows Remote Connection Protocol use? Port 3389 tcp.
Question 7: How to find out which ports are open on the remote computer and use the netstat-a-n command to check! There is some English in the statistics. Let me briefly talk about what these English words stand for.
Listening: Listening for connection requests from remote TCP ports.
SYN-SENT: Wait for the matching connection request after sending the connection request again.
SYN-RECEIVED: After receiving and sending another connection request, wait for the other party to confirm the connection request.
ESTABLISHED: indicates an open connection.
FIN-WAIT- 1: Wait for the confirmation of remote TCP connection interrupt request or previous connection interrupt request.
FIN-WAIT-2: Wait for the connection interrupt request from remote TCP.
CLOSE-WAIT: Wait for a hunger interrupt request from a local user.
Close: Wait for remote TCP to confirm that the connection is disconnected.
LAST-ACK: Wait for the confirmation of the original connection interruption request sent to remote TCP.
TIME-WAIT: Wait enough time to ensure that the remote TCP receives the confirmation of the connection interruption request.
Off: No connection status.
Question 8: What do ports 3389 and 23 in the computer mean? Port 3389 in the computer is the service port of Windows 2000(2003) Server Remote Desktop. You can use Remote Desktop and other connection tools to connect to a remote server through this port. If connected, you will be able to operate the remote computer just like a computer after entering the user name and password of the system administrator. Therefore, the remote server usually changes the value of the port or closes it.
Port 23 in the computer, service: Telnet. Remote login, the intruder is searching for the service of remote login UNIX. In most cases, scanning this port is to find the operating system running on the machine. And use it? Technology, intruders will also find the password. Trojan mini Telnet server opens this port.
Question 9: What is the difference between a remote port and a local port? Local address: an IP address assigned by DHCP or manually set, usually a private network address. Local port number: FTP: 23, Telnet: 23, * * TP: 25, DNS: 53,: 80,: 443. There are many port numbers corresponding to specific network programs, which can be viewed or modified in the settings. Remote address: public network ...
Question 10: What is the difference between a local port and a remote port? It's actually the same.
Is the local port relative to other computers on the network? The computer when the port is opened.
A remote port is a port that you need to open when accessing other computers on the network.
For example, if you use QQ, your local port is 4000 or 8000.
The essence is the same, but it needs relativity.
