+# go-tproxy
+
+Transparent proxy servers for HTTP, HTTPS, DNS and TCP.
+This repository is heavily under development.
+
+## Description
+
+**go-tproxy** provides transparent proxy servers for HTTP, HTTPS, DNS and TCP with single binary.
+Nothing needs to setup many tools. Nothing needs to configure iptables.
+**go-tproxy** will start multiple proxy servers for these protocols.
+Futheremore, it will configure iptables automatically.
+
+## Requirement
+
+**go-tproxy** supports only Linux iptables.
+
+## Install
+
+### Binaly install
+Download from [Releases page](https://github.com/wadahiro/go-tproxy/releases).
+
+### Source install
+Use Go 1.8.
+
+```
+go get -u github.com/wadahiro/go-tproxy/...
+```
+
+## Usage
+
+```
+Usage:
+
+ go-tproxy [options]
+
+Options:
+
+ -dns-endpoint string
+ DNS-over-HTTPS endpoint URL (default "https://dns.google.com/resolve")
+ -dns-proxy-listen [host]:port
+ DNS Proxy listen address, as [host]:port (default ":3131")
+ -dns-tcp
+ DNS Listen on TCP (default true)
+ -dns-udp
+ DNS Listen on UDP (default true)
+ -http-proxy-listen [host]:port
+ HTTP Proxy listen address, as [host]:port (default ":3129")
+ -https-proxy-listen [host]:port
+ HTTPS Proxy listen address, as [host]:port (default ":3130")
+ -loglevel string
+ Log level, one of: debug, info, warn, error, fatal, panic (default "info")
+ -private-dns string
+ Private DNS address for no_proxy targets (IP[:port])
+ -tcp-proxy-dports port1,port2,...
+ TCP Proxy dports, as port1,port2,... (default "22")
+ -tcp-proxy-listen [host]:port
+ TCP Proxy listen address, as [host]:port (default ":3128")
+```
+
+Proxy configuration is used from standard environment variables, `http_proxy`, `https_proxy` and `no_proxy`.
+Also You can use **IP Address**, **CIDR**, **Suffix Domain Name** in `no_proxy`.
+
+### Example
+
+```
+# Set your proxy environment
+export http_proxy=http://foo:bar@yourproxy.example.org:3128
+
+# Set no_proxy if you need to access directly for internal
+export no_proxy=example.org,192.168.0.0/24
+
+# Start go-tproxy with admin privileges(sudo)
+sudo go-tproxy -private-dns 192.168.0.100
+```
+
+For testing, using docker is easy way. Now, you can access to google from docker container with no proxy configuration as follows.
+
+```
+docker run --rm -it centos curl http://www.google.com

+
+## Current Limitation
+
+* HTTP proxy: `no_proxy` only works with IP Address and CIDR if your http client doesnt't add Host header, e.g., HTTP 1.0.
+* HTTPS proxy: `no_proxy` only works with IP Address and CIDR if your https client doesn't support [SNI](https://en.wikipedia.org/wiki/Server_Name_Indication).
+* TCP proxy: `no_proxy` only works with IP Address and CIDR.
