In order to avoid other people to the non-filing of the domain name resolution to their server IP and the server is broken network, you need to set the Nginx on the IP access to the server, only through the domain name access. The most critical point is to add this line to t

To avoid this situation, after each wireless access point is inserted into the installation location, ensure that it is powered on, the status indicator is operating properly, and each wireless access point is installed to obtain network and Internet connections. Check the signal level of the wi
We will encounter a lot of malicious IP attacks when using, this time will use Nginx prohibit IP access. Let's take a look at Nginx's default virtual host when users access through IP, or through an unnamed domain name (such as when someone points his own domain name to your
issue that should be noted is that the router does not filter the IP generated by itself. In the experiment, packets should be sent from other devices for testing.(2) When configuring standard IP Address Access Control List 1, all network segments except 30.1.1.0/24 are defined to be accepted.(3) Access Control List 1
Today to set a ban on the Nginx IP access to the server, only through the domain name access, this is to avoid other people to the record of the domain name resolution to their own server IP and cause the server was disconnected from the network to the following solutions:
Nginx's default virtual host takes effect wh
can bind the user's IP address to the user's connected port VID so that the device can identify whether the user is legal by verifying the IP address and VID. However, the problem with this solution is that the user IP address is bound with the port where it is located, and only static IP addresses can be configured.
/apache/tomcat behind the Nginx through Request.getheader ("X-forwarded-for") the IP is still the original IP.
When the Nginx setting x-forwarded-for equals $proxy _add_x_forwarded_for:
If the request from the CDN does not set the XFF header (usually this does not happen), theXFF header is the IP of the CDN

IntroductionWith the rapid development of the Internet, people increasingly want to be flexible, fast, low-cost, anytime and anywhere access to the Internet. Because of these features, wireless communication technology is increasingly used in Internet access. In IMT-2000, it is stipulated that the third generation mobile communication system must support mobile IP

With high reliability, it is likened to "Wireless optical fiber" technology, it can realize bidirectional transmission of voice, data image, video, conference TV and other broadband services in the near distance, and support ATM, TCP/IP and MPEG-2.

technical point of view, is only a host to provide proxy services, it is not necessarily provided by network operators. But as far as I know, the mobile GPRS network currently has only one WAP gateway: 10.0.0.172, which has mobile provided for WAP browsing (HTTP) services. There is a point to note that the WAP gateway and the general sense of the LAN gateway is different, the standard WAP gateway only real
Article Title: convert a Linux server to a wireless access point. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Creating your own wireless access point includes the following step
Android G1 Bluetooth and wireless network, and APN Access Point settings
The Bluetooth of G1 now only supports Bluetooth headsets (supporting Bluetooth stereo). Like the new iPhone, G1 does not support Bluetooth data transmission and synchronization and can only wait for the system to upgrade.
G1 has powerful wireless connectivity. Currently, 54m is supported in the latest 5.0.2hr3 Rom.

The previous time travel to solve a problem, is to get access points, as well as login mode. The problem with the mobile network differential setting in this process is to use the Ntrip protocol. This is a bit of a pit, is the server side is not according to the Protocol to the standard processing of these validation data. The first is a socket connection, the socket connection on the Send protocol. This agreement is ntrip to do.Ntrip Agreement: Click
