Nginx implements TCP reverse proxy
By default, Nginx only supports http reverse proxy. To enable nginx to support tcp reverse proxy, you also need to add tcp proxy module support during
An overseas top-up Interface (HTTPS) on the line is often interrupted by my network problem, I want to use HK's machine to do an HTTPS reverse proxy and no certificate.At firstAt first, the idea was to proxy with Nginx TCP forwarding:Add --with-stream option when compiling Nginx,upstream backend { server xxxxxx.com:443 ;}server { listen 443; proxy_pass ba
The Nginx TCP proxy function is provided by the Nginx_tcp_proxy_module module while monitoring the backend host status. Modules included in the module are: Ngx_tcp_module, Ngx_tcp_core_module, Ngx_tcp_upstream_module, Ngx_tcp_proxy_module, Ngx_tcp_upstream_ip_ Hash_module.

There is a number of reasons to has a TCP proxy in your tool belt, bothFor forwarding traffic to bounce from host to host, but also when assessingnetwork-based software. When performing penetration tests in enterpriseEnvironments, you'll commonly be faced and the fact that's you can ' t runWireshark, that's you can ' t load drivers to sniff the loopback on Windows, orThat network segmentation prevents your
Nginx is not only an HTTP proxy server, it can also be easily built into a TCP proxy server.
First, let's look at the new development version of the build method

Nginx supports TCP proxy very early. But has not known its use, recently in the Nginx blog saw. Some practitioners apply it to database access to load balancing and to achieve read and write separation to improve the throughput of the database, here I will not tell the details of the implementation. is just the most theoretical design conjecture.DirectDB cluster. Divided into read db and write db. Writes DB
Python implements simple TCP proxy server, pythontcp
The example in this article describes how to implement a simple TCP proxy server in python and share it with you for your reference.
The specific implementation code is as follows:

default Nginx only support the reverse proxy http, to the Nginx to support the reverse proxy TCP, also need to increase the TCP Proxy module support at compile time, that is nginx_tcp _proxy_moduleThe following steps only let nginx support tcp_proxy, do not add prce,gzip,SS
There is a server for Windows, now to be managed remotely, but the server is in the intranet, only through the front of the machine to jump, and the front of the Linux, need to use the TCP proxy, The server has nginx-1.2.9 installed and intends to use the Nginx TCP proxy module, the following is the installation config
Nginx only supports the reverse proxy of HTTP, want to support the reverse proxy of TCP, need to increase the TCP proxy module "Nginx_tcp_proxy_module" at compile time

Nginx-1.9.7 TCP reverse proxy (short)
This is called reverse proxy. It just seems that the structure is similar to the Nginx-Tomcat reverse proxy cluster. it's not official ~Add the script address to the end

The TCP proxy can forward traffic from one host to another, and can act like a wireshark, understand unknown protocols, and modify packets sent to the application.
Main reads the command line, parses, invokes Server_loop to listen for connection requests, and when a new request arrives, it is handed to proxy_handler for processing.
Proxy_handler: Every 1 bit of data received, sent to the target remote host.

In penetration testing, you often encounter situations where you cannot use Wireshark, sniffing, and analyzing traffic, by deploying a simple TCP proxy script to understand unknown protocols, modifying packets, or creating an environment for fuzzy tests. introduce principle
The agent works roughly as follows: [requires agent] to send request information to the server. [Agent] answer. Send the destination IP
According to the previous Nginx tcp proxy module trial settings, tcp connections are often dropped in the test environment. Find an issue on the project site and talk about it, but others use the web socket protocol. The README configuration cannot be used in the production environment. My configuration is as follows:

As the title shows, Nginx can act as a port forwarding after version 1.9, that is, to access the specified port of the server, Nginx can act as a port forward to redirect traffic to another server, obtain the return data of the target server, and return it to the requester. Nginx's TCP proxy function differs from the reverse proxy of Nginx: All traffic that reque
