Cracking method of restricting the use of routers by Netcom in Taian area

Install firewalls on all * * * clients and set the security level to the highest. Cancel all the rules in IP configuration rules that allow others to access this machine. If you use WinXP, you can also open the firewall directly in the network card settings.

Crack 2:

Turn off SNMP protocol in ADSL Moden; If you can't modify this agreement, you have to change to a cat that can change the settings.

Crack three:

* * * Enjoy installing WIN2000 server edition on the host in the Internet, and then disable the port 16 1 or disable the port 16 1 on the firewall.

Crack "Network Pioneer"

Recently, broadband ISPs in many places have used a device called "network guardian" to restrict users from surfing the Internet, which has brought a lot of inconvenience to everyone. Through the unremitting efforts of experts, they have been able to crack the "network guardian". Attention should be paid to distinguish "network guards" from recent virus attacks. ADSL modems usually need to be restarted when they are attacked by viruses, while people infected by "network guards" can surf the Internet for several minutes, and it takes several times to open a web page. Through research, it is found that it uses a variety of methods to detect whether users use * * * to surf the Internet, thus restricting it. Let me crack it separately:

1. Check whether there are different MAC addresses in packets with the same IP address. If there are, judge that users like surfing the Internet. The solution is to change the MAC address of each computer to the same; There are many ways to modify it, so I won't go into details here. Use Google to search for the keyword "modify MAC address".

Second, through SNMP (Simple Network Management Protocol), multiple computers are found to enjoy surfing the Internet. Some routers and ADSL cats have built-in SNMP services, and users can check whether there is * * * function through corresponding tools. The following is the effect diagram provided by netizens to check the number of connected users of an ADSL modem through corresponding tools, in which the number of users enjoyed by * * * can be clearly seen.

If you want to know whether your router or big cat has opened SNMP service, you can use any scanning software (ipscan, superscan ...). If the 16 1 port is open, the built-in SNMP service is available. The solution is to disable the port 16 1 for SNMP.

Use the router or turn on the routing mode of ADSL Cat * * *. Friends who like surfing the Internet can enter the management interface, and if there is an option to turn off SNMP, they can turn it off. If the cat's management interface doesn't have the option to turn off SNMP, you have to buy a router without SNMP service, such as TP-LINK TL-R400, put it between adsl moden and hub, and then make a NAT service in the router, so that the address of the cat entering adsl is an address, thus solving the problem of * * * enjoying the Internet.

3. Monitor the number of concurrent ports. If the number of concurrent ports exceeds the set number, it is judged as * * * enjoyment.

This is a setting that makes people laugh and cry. Network Guardian will continuously scan the number of ports opened by users. If it exceeds the set value, it is judged as * * * enjoyment. Sometimes even pressing F5 several times is considered as * * * enjoyment, and even affects a single user's surfing the Internet. This can't be cracked (unless you hack cyber guards). The solution here is to pretend that innocent users call ISP's customer service phone and curse, stating that it may not work.

Fourth, the "network guardian" also used an unknown method to detect the information enjoyed by * * * from the computer. The current solution is that all clients enjoyed by * * * should install firewalls and set the security level to the highest level. Due to the limited conditions, I only tried a few firewalls, and I found Kingsoft Internet Dart V(/Soft_Show.asp? SoftID= 10) is useful. All the IP configuration rules that allow others to access this machine are not allowed, and PING this machine is not allowed, so as to prevent ICMP and IGMP attacks. If it is WINXP, open the network firewall of the network card.

After adopting the above cracking method, I can't see this machine in my own LAN, and after WINXP opened the network firewall of the network card, I couldn't transfer files in QQ, and the network speed slowed down, but I can finally enjoy it again. If there is a good method, please tell us.

Generally speaking, "network leader" is still an immature product, which mainly affects individual users' surfing the Internet. Browsing web pages often needs to be refreshed several times, and some web pages are more complicated. When calling several server files, it also treats you as a * * * user, resulting in some web pages not being displayed. Moreover, because the "network guardian" kept scanning the user port to occupy bandwidth, the network speed slowed down. After using my ISP, the user's comments were so great that the customer service phone number was about to explode.
