LAN is what attacks me to have no packets to connect to

In an enterprise LAN, security is very important. If you attack people back and forth like this, no one will be able to get on the Internet when the time comes. I advise the landlord to think about how to protect more practically. As for LAN security, you can take a look at the Patrol Immunity Network Solution.

The Patrol Immune Network Solution is not a separate product, but a complete set of components composed of software and hardware, intranet security protocols, and security policies.

In the patrol immune network solution, various technical means are used to achieve the basic requirements of the immune network. For example:

1. By adding security functions to the access gateway equipment, such as ARP innate immunity, intranet firewall, filter window technology, etc., the requirements of integrated security functions in network equipment are realized;

2. Deploy the terminal immunity driver at the end node of the network by forcibly installing the terminal immunity driver. More importantly, the underlying protocol is also controlled at the NIC level to achieve in-depth defense and control.

3. Through the comprehensive setting, pre-determination and learning of the whole network-wide security policy combination, the active defense is realized, and the known and unknown attack behaviors are inhibited, intervened, and prevented from occurring.

4. Through the operation center running on the server, it handles the alarm information, abnormal traffic, identity verification, etc. from the gateway and terminal driver, audits and evaluates the operation status of the network, and is also responsible for the upgrade and issuance of security policies.

5. The intranet security and management protocol will access the gateway, server, terminal driver and other parts of the network equipment and security functions to form a complete system, and realize the linkage of the whole network equipment.

Good luck to the landlord.

Packets can't be received, sometimes it's a line problem, bad contact, you see if the light of the switch route is flashing, or the switch or route is set there.

Maybe this person's computer was infected with a virus and became a broiler, but I don't know it.

You can first use ARP to find the MAC address of this IP, and then log in to the router by yourself, and set the router to prohibit this MAC access.

But it's not a good way.,It's best to find the owner of the computer to communicate.,If it's a virus, you can help people.,If it's a bt e-donle that is too strong, you can coordinate it.。

The next P2PR software is very easy to use...

If you can't get on the Internet, the next software to change the MAC address changes the MAC address, disable the local connection and then enable it, so as to get a new IP-MAC address, if the attacker doesn't pay attention, you can surf the Internet temporarily! --This is a palliative!

The way to cure the root cause is to use the firewall of color shadow, which is very easy to use, and you can investigate and deal with the attacker's IP, and then the next ARP attack software will kill him, if you want to go down, you will get off NB, don't use P2P terminators, network law enforcement officers and other garbage!

It's best to find this person who attacks you to coordinate and coordinate.

There are two reasons to attack you, one is to attack deliberately, and the other is that there is a virus in his computer, and if the first reason is the first reason, it can only mean that this person is cheap.

Your computer is infected with the ARP virus, causing other computers to mistakenly think that you are the server, and constantly send you packets, causing your ports to be blocked, affecting your Internet speed, it is recommended that you install the ARP firewall and turn it on.

When someone attacks you with a cyber officer, you also need to install a cyber officer so that you can defend against it.

Agree with the mood on the second floor This kind of thing happens from time to time, it is a normal phenomenon, don't worry too much! It's okay to do a regular antivirus

Intermediate level is fine, don't worry, it's okay with a firewall!

It's normal for this to happen when accessing the network!

It may be that 360 deleted some files of your XP by mistake, open the device manager to see if there is a driver that becomes an exclamation mark or question mark, fix it and try, and then say that the 360 APR attack is not necessarily a human attack, my computer is automatically obtained IP, if you change the boot order, many times there will be such a report, in fact, it is just an IP conflict, if you have more LAN computers, it is best to turn on the firewall, routers generally have 3 firewalls, IP, network card address, external network connection, It can also be called a filter, or it can be called a binding, but in fact, it is commonly referred to as a firewall. After setting it up, there will be no such imagination, even advanced hackers can't enter these 3 levels.

What do you do with that? Take a look at your router and network card drivers.

Take a look at your 360 ARP gateway settings, is it not set up on this computer?

Anti ARP SNIFFER is a software that can determine ARP packets, and the wrong ones will be rewritten... This can be prevented... P2P Terminator, or search for P2P Terminator Anti-Kill, you can find Anti-Kill P2P software...

Ignore the virus first.

First, there is something else to know.

1.Are you the only one of the four machines, or are you all there? What model is the hub? How did you insert the hole?

2.Have you ever tried to get an IP address automatically?

3.Have you set a fixed IP address, do you have a fixed DNS server address?

Install this patch and try.

DNS is set to the DNS address of the local broadband operator, just ask if you don't know.

First of all, can you ping the Internet? What a limit. If you can't access the Internet if you have to go to the Internet because of a virus attack!

See if the firewall is blocked? Or is it someone else's setting that won't let you get on?

If your router doesn't have DNS set, you don't need to set DNS to your router's address. Manually set the DNS provided by the ISP.

Faint, you're amazing. The DNS server is set to the IP address of the login host, is the login host a DNS server? If not, you can't set this up.

This virus is responsible for the ARP in the network. This is an ARP (mutant virus) that was discovered just a few days ago

1.It is recommended that the landlord have all the equipment including the computer.

2.Comprehensive anti-virus.

3.Then restart one by one OK.
