There are many group friends who don't know the preparation of grey pigeons. Now I will elaborate on how to prepare them: 1. In the external network, adsl user ip is generally dynamic. You can register your domain name in www.3322.org. For example, my registration number is door8.3322.org. If my current external ip is 222.222.222.222, then turn door8.3322.org into 222.222.222.222. 2. In the intranet. Generally, it is an Internet cafe or an office LAN. In this case, it is necessary to make port innuendo. Let me talk about my thoughts. If you can access the router, it is generally192.168.0.1or 192. 168. 1. The account password is admin admin, which is the default password in the browser. Enter the ip of the route and the passwords of various types of routers. You can check it in Baidu.com, and then map the 8000 port of the external ip of the Internet cafe to your internal ip, such as 192. 168.0.5. If you can't get in, don't try to crack it violently. This is not feasible! If you can't get into the route: a. Scan a network segment with showip (pure ip). For example, Anhui B. scanned port 3389 of this network segment with ssport (scanner) and found that the general account of weak password is administrator new guest. After entering, end the firewall and antivirus software (to avoid being found). C. after entering, open door8.ys 168.com (my network hard disk). Download and open your port mapper. The port mapping program is generated by Grey Pigeon (step: Open Grey Pigeon-Tools-Intranet Port Mapping Tool-and then generate). After running, remember to add 9999 (the default port of the port mapping tool) as an exception port in the windows default firewall to avoid being banned from running. (This is very important) D. Remember this external ip, such as1111.11. Then connect with the gray dove (Steps-Tools-Intranet Port Mapping Tool-Enter11.1.11165438+), thus establishing a shadow with the ip of the extranet. E. log in to www.3322.org and change the ip of door8.ys168.com+011165438. 38+0, so that your broilers can find door8.ys 168.com first. Then read the IP111.1.11.565438.56586666 8+01.668. 000 port, so that your pigeon will automatically go online. If you ask a friend to insinuate for you, update the ip with the domain name. Then, because port 8000 has been occupied by your friend's pigeon, we can't use parsing, so we use domain name translation. For example, my door8.go.3322.org goes to http:/11.1.11. In this way, the pigeon is connected to port 9000 of111.11. Then use the pigeon connection111.1.11to map his 9000.
