ScenarioBecause the company's intranet has multiple servers whose http services need to be mapped to the company's Internet static IP address, if you use the routing Port ing, you can only map the port 80 of an intranet server to the Internet port 80, port 80 of other servers can only be mapped to non-Port 80 of the Internet. Non-Port 80 ing requires adding ports to the domain name during access, wh

Let's say your server IP is 211.147.9.106 1 First, you should know which DNS server is responsible for this IP's reverse domain name resolution. You can use this page to query reverse domain name resolution information http://www.dnsstuff.com/tools/ptr.ch?

Because the company intranet has more than one server HTTP service to map to the corporate extranet static IP, if you use the port map of the route to do, only one intranet server 80 port mapped to the external network 80 port, the other server's 80 port can only be mapped to the external network of non-80 port. Non-80 port mapping in the time of access to the domain name plus port, more trouble. And the co

Domain Name reverse resolution query command If you do your own mail server, generally you need Reverse Domain name resolution, you can ask the IP provider for help. Domain Name reverse

Because the company intranet has more than one server HTTP service to map to the company's external network static IP, if the port map with the route to do, you can only one intranet server 80-port map to the extranet 80 ports, the other server 80 ports can only map to the outside of the network of 80 ports. Non-80-port mapping in the access time to the domain name plus port, more trouble. And the company p

IP address will not be allowed.This requires the Nginx and Apache configuration files to be set X-forwarded-for parameters to obtain the client's true IP address. For clients that use a reverse proxy, trace the real IP address./usr/nginx/conf/nginx.conf Add the following parameters: Proxy_set_header Host $host

The company has three machines in the computer room, because the IP is not enough, must be separated, so to establish a single IP multi-domain reverse proxy,is when request www.abc.com jump to this machine, request www.bbc.com jump to 192.168.0.35 machine up,The premise 192.168.0.35 installed nginx and PHP environment.

Recently a small station to start a Ali cloud server, in fact, because the foreign server is too card, even SSH connection cards, simply can not use, so start a, but that foreign VPS replaced the hen, China Telecom's export broadband and normal, so there are two, just recently in the "actual combat Nginx", Also in the site to see a lot of articles on the Ngnix agent, so I intend to actually try to test: 1. First, the reverse proxy schematic diagram t

Nginx reverse proxy, the servlet application via request.getremoteaddr () IP is nginx IP address, not the client real IP, through the Request.getrequesturl () access to the domain name, protocol, Ports are domain names, protocols,

Nginx reverse proxy is a common function of the process of Web layout. After setting the reverse proxy, by reading the HTTP header inside the REMOTE_ADDR can not get the true user IP, we need to increase the nginx configuration to solve this problem. The following is an experiment to illustrate. Configure 1 Nginx servers and configure 3

A friend:For example, if your mail server's fixed IP address is 218.5.x.x, you can use NSLookup to check whether reverse resolution is successful.

This is the function that Nginx originally provided.

problem number, which is used by the query end to differentiate itself from the query. The next 16 bits can be further subdivided to indicate the nature and details of the message, such as querying or responding to the message, whether or not recursive query is required (generally, the server supports recursive query without any settings. This is the case for BIND) Query problems are followed by query types, including a, NS, cname, PTR, HINFO, and MX. If you are familiar with bind, you will k
