Local three-level execution: The local and upper ports are the same. Suppose there is already a normal SS or SPS proxy (ss is enabled, encryption: aes-256-cfb, password: demo): 127.0.0.1:8080, now we turn it to support both http(s) and socks5 and The ordinary proxy of ss, the converted local port is 18080, the converted ss encryption mode: aes-192-cfb, ss password: pass. years, which is why you don't see much for code changing. Term meaning multiple different layers across many eras? 100 is the maximum number of connections for this IP, not limited to write 0 proxy socks -t tcp -p ":8080" -T kcp -P "22.22.22.22:38080" --kcp-key mypassword proxy sps -S socks -T tls -P 127.0.0.1:8080 -t tcp -p :18080 -C proxy.crt -K proxy.key -h aes-192-cfb -j pass, Suppose there is already a kcp socks5 proxy (password: demo123): 127.0.0.1:8080, now we turn it into a common proxy that supports both http(s) and socks5 and ss. Limit the maximum number of global connections for the proxy service, a number, 0 is unrestricted, default is 0. When the user connects, the proxy will request the url ("http://test.com/auth.php") in GET mode. This parameter specifies a file, one line per rule, in the format: "username: password: number of connections: rate: upstream". A lot of HTTP Client across languages already support this in a very transparent way. 2 Answers Sorted by: 1 If you want to use SSH for a remote shell session you should not use the websocket package but the golang.org/x/crypto/ssh package. http://test.com/auth.php?user=a&pass=b&client_addr=127.0.0.1:49892&local_addr=127.0.0.1:8100&target=http%3A%2F%2Fwww.baidu.com&service=http&sps=0. When the UDP upstream proxies (parameter: -T) is udp, it supports the specified outgoing IP. The proxy supports the cluster management. The code that I have written is in go-playground. Execute on vps Starting from version v13.2, outgoing supports multiple subnet formats separated by commas. This project will continue to update the iterations and continue to release the full platform binary program, providing you with powerful and convenient proxies tools. proxy http -t tls -p ":38080" -C proxy.crt -K proxy.key. The author of this project found that a large number of developers based on the project for secondary development or using a large number of core code of the project without complying with the GPLv3 agreement, which seriously violates the original intention of using the GPLv3 open source agreement in this project. If the ingress IP is an intranet IP, the egress IP does not use the ingress IP. Then access the local port 8080 is to access the proxy port 38080 on the VPS, the data is transmitted through the kcp protocol, note that the kcp is the udp protocol, so the firewall needs to release the 380p udp protocol. Authenticate every connection, regardless of whether client authentication is required. proxy sps -T tcp -P 3.3.3.3:8888 -M -t tcp -p :8080 --disable-socks, proxy socks -p 2.2.2.2:33080 -z password -t tcp, proxy sps -S socks -P 2.2.2.2:33080 -T tcp -Z password -l 100K -t tcp -p :33080. proxy tcp -p ":28080" -T tcp -P "22.22.22.22:38080" Level 3 HTTP proxy (local) At this time, you can use the -g parameter to add the vps external network ip to prevent the infinite loop. And you can see the output log content of the proxy through the log file. In this way, when the website is accessed through the local agent 8080, the target website is accessed through compression with the upstream. With --always, all HTTP proxy traffic can be forced to go to the upper HTTP proxy. Custom underlying encrypted transmission, http(s)\sps\socks proxy can encrypt tcp data via tls standard encryption and kcp protocol on top of tcp, in addition to support custom encryption after tls and kcp, that is Said custom encryption and tls|kcp can be used in combination, the internal AES256 encryption, you only need to define a password when you use it. If an incorrect IP is bound, the proxy will not work, the proxy will try to X-Forwarded-Host They come in many flavours. Features Listening on multiple ports Multi-level forward proxies - proxy chain Standard HTTP/HTTPS/HTTP2/SOCKS4 (A)/SOCKS5 proxy protocols support Probing resistance support for web proxy TLS encryption via negotiation support for SOCKS5 proxy Support multiple tunnel types Tunnel UDP over TCP Local/remote TCP/UDP port forwarding Support intranet penetration, protocol supports TCP and UDP. proxy http -p "0.0.0.0:8090" -T tcp -P "22.22.22.22:8080" -b blocked.txt -d direct.txt. Also, the idea that I wrote about putting a wait just epsilon bellow the time-out, would that work in the worst-case or only on average? #1 When multiple upper-level load balancing is a weighting strategy, the weights are rarely used. Domain name black and white list, more free to control the way the website is accessed. proxy socks -p ":33080" --dns-address "8.8.8.8:53" --dns-ttl 300. client_addr: client address, format: IP: port. In fast global The detailed description is as follows: By default, the -C, -K parameter is the path to the crt certificate and the key file. Chained proxies, the program itself can be used as an proxies, and if it is set up, it can be used as a secondary proxies or even an N-level proxies. bind the target without binding the IP, and the log will prompt. Request parameter description: proxy help server You can fix the port number of the UDP function by the parameter --udp-port port_number, for example: proxy sps -t tcp -p "0.0.0.0:38080" --udp-port 38081. proxy bridge -p ":33080" -C proxy.crt -K proxy.key Under the hood, a forward proxy is the HTTP method CONNECT. The proxy's http(s)/socks5/sps proxy API function is controlled by three parameters: --auth-url and --auth-nouser and --auth-cache. 0 means no limit. Execute on vps proxy tcp -t tls -p ":38080" -T udp -P "8.8.8.8:53" -C proxy.crt -K proxy.key Execute on the secondary vps (ip: 3.3.3.3): Go's net package provides a portable interface for network I/O, including TCP/IP, UDP, domain name resolution, and Unix domain sockets. We can also specify the black and white list file of the website domain name, one domain name and one domain name, the matching rule is the rightmost match, for example: baidu.com, the match is ..baidu.com, the blacklist domain name domain name goes directly to the upstream agent, white The domain name of the list does not go to the upstream agent; if the domain name is in the blacklist and in the whitelist, the blacklist works. When the http protocol is used to request the ip:2500 port of the server, the header HOST field of http will be set to local.com. proxy server -r ":28080@:80" -r ":29090@:21" --k test -P "127.0.0.1:33080" -C proxy.crt -K proxy.key, The full format of -r is: PROTOCOL://LOCAL_IP:LOCAL_PORT@[CLIENT_KEY]CLIENT_LOCAL_HOST:CLIENT_LOCAL_PORT. Level 1 SOCKS proxy VPS_01, IP: 22.22.22.22 We can specify an http url interface address with the --auth-url parameter. If the returned data contains both: user or ip, and conns, then the user or ip will be ignored, and only the connection matching conns will be disconnected. Now we want to use pc and vps01 and vps02 to build an encrypted channel. The proxy can reverse proxy http and https websites. The proxy will report the traffic used for this connection to this address.Specifically, the proxy sends an HTTP to GET request to the HTTP URL address set by --traffic-url. The command is as follows: --intelligent=direct, the targets in the blocked are not directly connected. The good news is that this is amazingly easy in go, and the core part of this proxy will be: go io. Integrating with Third-Parties via a Go Forwarding HTTPS Proxy TCP is a stream protocol, and all you can do is shuttle bytes back and forth. Pass: password The analogy that I like to use to explain why I think this method doesn't work is the following: Say we have a cup and the proxy is drinking half the cup every time it does a read from the server, but the server only puts 1 teaspoon at a time. Demand: random IP selection. The format of the server-http-host parameter is as follows: --http-host www.test.com:80@2200, if the server listens to multiple ports, just repeat the --http-host parameter to set the HOST for each port. However, I am unsure why that would be correct. Local execution: proxy http -t kcp -p ":38080" --kcp-key mypassword. Set by parameter --udp-port 0, 0 represents a free port is randomly selected, or you can manually specify a specific port. The format in configfile.txt is that the first line is the name of the subcommand, and the second line starts with one parameter per line. If the --udp parameter is not specified, PROTOCOL defaults to tcp, then: -r ":8080@:80" defaults to tcp; 4.7.2. Normal:--nodelay=0 --interval=40 --resend=2 --nc=1 upstream: The upstream used, not empty, or not set this header. If the child process exits abnormally, restart the child process after 5 seconds. header. Secondary TCP proxy VPS_02, IP: 33.33.33.33 The command is as follows: The --traffic-url URL must response the HTTP status code 204. Connections matching the returned conns will be disconnected by the proxy. The following command sets 23.23.23.23 with the -g parameter. Limit the speed of each tcp connection of the service, for example: 100K 2000K 1M . 2.2.2.2:33080 is the upstream address, the format is: IP (or domain name): port , if the underlying is ws/wss protocol can also bring the path, such as: 2.2.2.2: 33080/ws; enabled. The intranet penetrating bridge can set the client key whitelist. The authenticated user name and password file. as: Multi-link version, the corresponding sub-command is tserver, tclient, tbridge. In this way, when the website is accessed through the local agent 8080, the target website is accessed through encrypted transmission with the upstream. Local execution: Use the --ip-deny parameter to specify a client IP blacklist list file, then the connection will be disconnected when the user's IP is in this file. Under normal circumstances, it is sufficient to listen on one port, but if you need to listen on multiple ports, the -p parameter is supported. The sample file ip.limit, the rule format is as follows: This mode needs to have a certain network foundation. iptables -t nat -X PROXY, Delete rule from selected chain iptables -D chain name rule details e.g. The proxy's http(s) proxy can encrypt tcp data via tls standard encryption and kcp protocol on top of tcp, in addition to support customization after tls and kcp. Then this time The certificate file goproxy.crt and the key file goproxy.key will be generated under the current program directory. Report in fast global mode proxy tcp -p ":38080" -T tcp -P "66.66.66.66:8080" proxy sps -S http -T tls -P 2.2.2.2:8081 -t tls -p :8082 -C proxy.crt -K proxy.key, Then run a sps node on the pc and execute: If you need a connection from all ports, connect to the upper specified port, you can add the parameter --lock-port. Building a proxy server in Golang - GitHub Pages proxy http -t tcp -p ":8080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key usage in real time. A reverse HTTP proxy over WebSocket is a type of proxy server which uses the WebSocket protocol as a "tunnel" to pass TCP communication from server to client. For example: -r "udp://:10053@:53" -r "tcp://:10800@:1080" -r ":8080@:80" --auth-file, --max-conns, --ip-limit, --rate-limit, -a These five parameters control. Thus, its illegal to consider correct behaviour if the proxy goes, reads the connection again at a later time after it already wrote to the client, and sends the missing chunk at a later time, maybe during the response of a different request). Whoever resolves the fastest resolution will use the resolution result. Steps: WebSocket is designed to work over HTTP. In other cases, the authentication failed. When I forward the request from the proxy to the server, and get the response, how do I know when the server has sent me all the information that I need if I do not know beforehand the format of the data being sent from the server to the proxy (i.e. go-any-proxy is a server that can transparently proxy any tcp connection through an upstream proxy server. 1: The user sends the authentication information user-auth. Local execution: I have researched and read about coding in networking and it is still not clear to me how to do this. Only when the traffic is reported will the report be considered successful, and if it response other status codes, it will be considered that the reported traffic failed, and the log will be output. Cache authentication results, time can be set to reduce API pressure. Fast :--nodelay=0 --interval=30 --resend=2 --nc=1 For multiple binding requirements, you can repeat the --bind-ip parameter identification. I don't know if the response from the server is of the form of type-length-value scheme nor do I know if `\r\n\ indicates the end of the message form the server). Then the local UDP port 53 provides a secure anti-pollution DNS resolution function. If the parameter --lb-onlyha is used, only the high availability mode is used, then a node is selected according to the load balancing strategy, and this node will be used until it is not alive, then another node will be selected for using, thus cycling. Secondary SOCKS proxy (local Linux) The command is as follows: In Go project, gorilla/websocket is widely used to implement WebSocket. And the analysis result cache time (--dns-ttl) seconds, to avoid system dns interference to the proxy, in addition to the cache function can also reduce the dns resolution time to improve access speed. proxy sps -S http -T tcp -P 127.0.0.1:8080 -t tcp -p :18080 -h aes-192-cfb -j pass, Suppose there is already a tls http(s) proxy: 127.0.0.1:8080. The commands executed by the upstream agent are: proxy package - golang.org/x/net/proxy - Go Packages The sps itself does not provide the proxy function. However, in some cases, you need to fix the UDP function port. Level 3 TCP proxy (local) Something like this: First assume that these connection are semi-permanent (will be closed after a long long while) and I need the data to arrive in order. Then access the local port 28080 is to access the target address through the VPS. go-any-proxy is a server that can transparently proxy any tcp connection through an upstream proxy server. If the load balancing policy is hash, the default is to select the upstream based on the client address. proxy http -T tcp -P 2.2.2.2:7777 -M -t tcp -m -p :8888 Assume that I want to write a tcp proxy (in go) with the connection between some TCP client and some TCP server. proxy server -r ":28080@:80" -P "22.22.22.22:33080" -C proxy.crt -K proxy.key. Port Forwarding with Go - zupzup Secure DNS proxy, which can secure and prevent pollution DNS queries through encrypted proxy communication between the DNS proxy server provided by the local proxy and the upstream proxy. proxy tcp -t tcp -p ":23080" -T tcp -P "22.22.22.33:33080" --C. Local execution: The parameters of the multi-link version and the multiplex version are exactly the same. If it communicates with the upstream agent, it can perform secure and pollution-free DNS resolution. Local secondary execution: proxy dns --default direct -p :5353. The default is: parent. Tip: It is randomly specified during the protocol handshake process and does not need to be specified in advance. Leave it blank or unset this header if not needed.When the outgoing returned by the API is a subnet, and if you don't Tunnel Proxy : It is a proxy that is done through the HTTP body, which is a TCP-based application layer proxy that uses the CONNECT method of HTTP to establish a connection. How to use: upstream:http://127.0.0.1:3500?parent-type=tcp, //logic business, push invalid user into $badUsers, 5. Generate a self-signed certificate and key file with the following command. If the load balancing policy is weight, the -P format is: 2.2.2.2: 3880?w=1, where 1 is the weight and an integer greater than 0. proxy.exe http -t tcp -p ":8080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key Features Listening on multiple ports Multi-level forward proxies - proxy chain Standard HTTP/HTTPS/HTTP2/SOCKS4 (A)/SOCKS5 proxy protocols support Probing resistance support for web proxy TLS encryption via negotiation support for SOCKS5 proxy Support multiple tunnel types Tunnel UDP over TCP Local/remote TCP/UDP port forwarding Primary TCP proxy VPS_01, IP: 22.22.22.22 The content of control.php is as follows: The proxy http(s)/socks5/sps proxy function supports the user to access the proxy pair through the configuration file, and supports the http(s) proxy ``Proxy Basic proxy authentication` and the socks5 proxy authentication. It can be reported in the normal mode or in the fast mode. Features while supporting powerful cascading authentication. TCP and UDP Load Balancing | NGINX Documentation proxy udp -p ":33080" -T udp -P "192.168.22.33:2222" -B, Intranet penetration, divided into two versions, "multi-link version" and "multiplexed version", generally like a web service, this service is not a long-term connection, it is recommended to use "multi-link version", if it is to keep long The time connection suggests using a "multiplexed version.". Their situation is as follows: For the sps proxy we can perform username and password authentication. Does sending EOF's close the connection? A transparent tcp proxy (no decryption necessary) (golang). Other versions may not be applicable. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Sometimes the network where the proxy is located cannot directly access the external network. Local three-level execution: proxy socks -t tcp -p ":33080" --auth-url "http://test.com/auth.php" In this way, when the website is accessed through the local agent 8080, the target website is accessed through encrypted transmission with the upstream. For multiple users, repeat the -a parameter. Use local port 8090, assuming the upstream HTTP proxy is 22.22.22.22:8080, proxy http -t tcp -p "0.0.0.0:8090" -T tcp -P "22.22.22.22:8080". That is http proxy over TLS, socks over TLS. For example: This "target" is generally a website or an arbitrary tcp address. golang tcp forward proxy GitHub Help on a Golang TCP Forward Proxy - Getting Help - Go Forum The format of the black and white domain name list file is as follows: 2. proxy http -t tcp -m -p :7777 "tcp / http / socks / sps" supports listen on multiple ports and range ports. upstream: proxy sps -S http -T tcp -P 127.0.0.1:8080 -t tcp -p ":33080" -a "user1:pass1:0:0:" -a "user2:pass2:0: 0:" Client service parameters can use placeholders: {AGENT_ID} to refer to the agents id as the clients key, so as to ensure that each client has a unique key. GOST | GOST v2 proxy http -T ssh -P "2.2.2.2:22" -u user -D demo -t tcp -p ":28080", Local HTTP(S) proxy port 28080, executing: Https,socks5s represents the http and socks5 agents protected by tls. For example: user:pass:100:10240:http://192.168.1.1:3100 The following formats are supported for subnets: Example: 192.16.1.1,192.161.1.2,192.168.1.2-192.168.1.255. userTotalRate Limit the user total bandwidth speed (bytes per second), unit is byte, not limited to 0 or not set proxy http -t tcp -z demo_password -p :7777 proxy udp -p ":5353" -T tls -P "33.33.33.33:28080" -C proxy.crt -K proxy.key select an IP from the subnet as the outgoing IP. Package tcpproxy lets users build TCP proxies, optionally making routing decisions based on HTTP/1 Host headers and the SNI hostname in TLS connections. Custom encryption requires both ends to be proxy. The proxy needs authentication, username: username password: password Server Configuration First of all, we might note that allowing tunnels through ssh connections might be a security liability, as it can pierce our firewall policies. mode, for a --traffic-url, The proxy http(s) proxy can encrypt tcp data through tls standard encryption and kcp protocol on top of tcp, and can also compress data before custom encryption. github.com/magisterquis/connectproxy - Go Packages Compression is divided into two parts, one part is local (-m) compression transmission. Then access the local port 8080 is to access the proxy port 38080 on the VPS. If a crystal has alternating layers of different atoms, will it display different properties depending on which layer is exposed? proxy socks -t tcp -p ":33080" -a "user1:pass1" -a "user2:pass2" Secondary TCP proxy VPS_02, IP: 33.33.33.33 If you want to get more detailed configuration and explanation of kcp parameters, please search for yourself. If it does its not a method that I want to use. We read every piece of feedback, and take your input very seriously. The proxy's http (s) / socks5 / sps / tcp / udp proxy function supports traffic reporting. proxy socks --always -t tls -p ":28080" -T tls -P "22.22.22.22:38080" -C proxy.crt -K proxy.key, Local SOCKS5 proxy port 28080, execute: Can perform: Use the --ip-allow parameter to specify a client IP whitelist file, then the connection will be disconnected when the user's IP is not in the file.
