How to prevent chat messages from being intercepted in the LAN? Thank you

It's not easy...

Network monitoring technology In the network, when the information is transmitted, tools can be used to set the network interface in the monitoring mode, and the information being transmitted in the network can be intercepted or captured, so as to carry out attacks.

Network snooping can be implemented in any location mode in the network. Hackers generally use network snooping to intercept user passwords. For example, when someone occupies a host, then he wants to expand the results to the entire LAN where the host is located, and listening is often the shortcut they choose.

A lot of times I've seen beginners on various security forums who think that if they take over a host, then it should be easy to get into its intranet. In fact, it is not easy to enter a host and then transfer to other machines in its internal network. Because in addition to getting their passwords, you also have an absolute path that they share, and of course, there must be write permission at the end of this path.

At this point, running a listener on a host that is already being controlled can be very effective. However, it is a laborious task, and it also requires the patience and adaptability of the person concerned. These include:

Interception of data frames.

Analyze and categorize data frames.

Detection and prevention of DoS attacks.

IP spoofing detection and attacks.

Application on network detection.

Initial filtering of spam.

This is indeed very difficult to prevent, tell me about my method:

1.Pay attention to personal selfishness, and check if there ......are people around you before sending important messages-2.Anti-network interception:

Like email, http+++s is encrypted......3.Search the Internet for related hacking tools Beware of poisoning......ps:This I have a cracked version of the version is a little lower If you want to leave a message, I'll send you....Hehe.

Can't prevent it, as long as someone else ctrl+alt+a, you can take a screenshot, if you want to protect your privacy, pay attention to it when you chat, hehe.

You don't need any software. Of course, you have to know the other party's IP address, and then in the command prompt:

net send **message

That is, the asterisk above is the IP address of the target machine's LAN, and meaasge is what you want to say.

Most of the time this is successful. If it doesn't work, it may be that your messenger service is not started or the other party has turned off the service, start it as follows:

My Computer (right-click) Manage Services & Applications Services, find Net Meaaenger, and start it.

Well, that's it, I hope it can help you :)

It can be used in win2000.

Net Send hostname or IP "message".

Send a message, but the other party can't send it if the MSG protocol is turned off.

You can use the netmeeting that comes with the system.。。

XP and 2000 come with LAN chat commands.

Enter cmd to enter the command prompt during operation, and enter winchat to start the chat program.

Or net send the other party's IP content.

First, enter ipconfig in the command prompt to see if there is an IP address or gateway.

Again, check whether the network cable is not in good contact, it is possible that the network cable is broken, try to change the network cable.

Then, ask the network administrator if they have blocked your IP.

Take a look at the IP address of the other computer and change your IP address to the last digit and try the same settings as you do.

If you look at the network cable, it is best to find someone in the company who manages the network.

It has nothing to do with the machine with a hard disk, you just need to map the diskless system on the server side and kill the virus. It can also be uploaded after virus killing on the terminal.

The diskless system can be reinstalled on the host or open a superuser.

I just got the viking from yesterday

Some variants don't work at all now, so it's recommended to refer to my rookie method:

1. Find relevant information to see what related processes and registry keys and startup items are all terminated, deleted and disabled.

2. Disconnection. 3. Comprehensive anti-virus, look at the path of the virus.

Delete them all, and those that can't be deleted are shredded with files.

4. What suspicious software programs have been downloaded recently, delete + uninstall.

5. Use Optimizer to clean up.

6. Restart. 7. If the desktop icon is blank, run, refuse to modify when prompted to modify the registry (antivirus software monitoring will prompt whether to modify), and right-click the attribute change icon if it is successfully restored, it is OK.

8. Restart, if it is slow, restart it 1 time, if it is too slow and forcibly shut down, you can also pay special attention: the startup item rundl132 looks like rundll32, run msconfig, disable it; Run regedit to search for related items to delete.

If there is anything in the root directory of each pan, delete the powder.

system folder.

Just kill a hard drive, disconnect the network.

Add all other hosts to the antivirus software's scans.

In addition to firewall software protection, the easiest and most convenient way is to use **IP. In this way, in the process of using the Internet, our real data is hidden and encrypted transmission. The most important thing is that it can use AES technology to encrypt online data, and at the same time provide domestic network acceleration services, without configuration, saying goodbye to delay and stuck.

Open the router settings interface and bind it. The general router setting is admin for password

To do IP two-way binding, that is, to bind IP on the gateway server, that is, the router, and your machine respectively. The setting of the route should refer to the corresponding model, the binding on the machine; arp

s IP to be bound

The MAC address to be bound.

The MAC address can be viewed in ipconfig.

Hello: Upstairs misunderstanding, since the landlord is in the LAN, it must be connected through a router or switch, assigned by the router IP, if there is an IP conflict, it means that someone is the same as the IP set by the landlord, if it is a few people in the family with a router, you can negotiate to modify the IP on the line, if it is a company, you can apply to the network administrator to bind the IP address.

I believe that the landlord will modify the IP, and if you don't, you can ask.

Let me tell you how. I don't know if that's feasible for you. Create a text after booting.

Type something in. Whatever you want, don't save it. Then shut down, and he'll remind you whether to save the file and what to move the dialog box aside.

Don't order anything. Plug in the USB flash drive and see if it is readable.
