Dumbest HTTP proxy ever.
- Cross-platform (Windows/Mac OS/Linux/Android (via shell)/*BSD)
- Deployment with a single self-contained binary
- Zero-configuration
- Supports CONNECT method and forwarding of HTTPS connections
- Supports
Basic
proxy authentication - Supports TLS operation mode (HTTP(S) proxy over TLS)
- Native ACME support (can issue TLS certificates automatically using Let's Encrypt or BuyPass)
- Supports client authentication with client TLS certificates
- Supports HTTP/2
- Resilient to DPI (including active probing, see
hidden_domain
option for authentication providers) - Connecting via upstream HTTP(S)/SOCKS5 proxies (proxy chaining)
- systemd socket activation
Pre-built binaries available on releases page.
Alternatively, you may install dumbproxy from source. Run within source directory
go install
Docker image is available as well. Here is an example for running proxy as a background service:
docker run -d \
--security-opt no-new-privileges \
-p 8080:8080 \
--restart unless-stopped \
--name dumbproxy \
ghcr.io/senseunit/dumbproxy
sudo snap install dumbproxy
Just run program and it'll start accepting connections on port 8080 (default).
Run proxy on port 1234 with Basic
authentication with username admin
and password 123456
:
dumbproxy -bind-address :1234 -auth 'static://?username=admin&password=123456'
Run HTTPS proxy (HTTP proxy over TLS) with automatic certs from LetsEncrypt on port 443 with Basic
authentication with username admin
and password 123456
:
dumbproxy -bind-address :443 -auth 'static://?username=admin&password=123456' -autocert
Run HTTPS proxy (HTTP proxy over TLS) with automatic certs from BuyPass on port 443 with Basic
authentication with username admin
and password 123456
:
dumbproxy \
-bind-address :443 \
-auth 'static://?username=admin&password=123456' \
-autocert \
-autocert-acme 'https://api.buypass.com/acme/directory' \
-autocert-email [email protected] \
-autocert-http :80
It's quite trivial to set up program which supports proxies to use dumbproxy in plain HTTP mode. However, using HTTP proxy over TLS connection with browsers is little bit tricky. Note that TLS must be enabled (-cert
and -key
options or -autocert
option) for this to work.
Open proxy settings in system's network settings:
Turn on setup script option and set script address:
data:,function FindProxyForURL(u, h){return "HTTPS example.com:8080";}
where instead of example.com:8080
you should use actual address of your HTTPS proxy.
Note: this method will not work with MS Edge Legacy.
Open Firefox proxy settings, switch proxy mode to "Automatic proxy configuration URL". Specify URL:
data:,function FindProxyForURL(u, h){return "HTTPS example.com:8080";}
Use any proxy switching browser extension which supports HTTPS proxies like this one.
Specify proxy via command line:
chromium-browser --proxy-server='https://example.com:8080'
Use any proxy switching browser extension which supports HTTPS proxies like this one.
It is possible to expose remote HTTPS proxy as a local plaintext HTTP proxy with help of external application which performs remote communication via TLS and exposes local plaintext socket. steady-tun appears to be most suitable for this because it supports connection pooling to hide connection delay.
- Run proxy as in examples above.
- Install Adguard on your Android: Guide.
- Follow this guide, skipping server configuration. Use proxy type HTTPS if you set up TLS-enabled server or else use HTTP type.
- Enjoy!
Authentication parameters are passed as URI via -auth
parameter. Scheme of URI defines authentication metnod and query parameters define parameter values for authentication provider.
none
- no authentication. Example:none://
. This is default.static
- basic authentication for single login and password pair. Example:static://?username=admin&password=123456
. Parameters:username
- login.password
- password.hidden_domain
- if specified and is not an empty string, proxy will respond with "407 Proxy Authentication Required" only on specified domain. All unauthenticated clients will receive "400 Bad Request" status. This option is useful to prevent DPI active probing from discovering that service is a proxy, hiding proxy authentication prompt when no valid auth header was provided. Hidden domain is used for generating 407 response code to trigger browser authorization request in cases when browser has no prior knowledge proxy authentication is required. In such cases user has to navigate to any hidden domain page via plaintext HTTP, authenticate themselves and then browser will remember authentication.
basicfile
- use htpasswd-like file with login and password pairs for authentication. Such file can be created/updated with command like this:dumbproxy -passwd /etc/dumbproxy.htpasswd username password
or withhtpasswd
utility from Apache HTTPD utils.path
parameter in URL for this provider must point to a local file with login and bcrypt-hashed password lines. Example:basicfile://?path=/etc/dumbproxy.htpasswd
.path
- location of file with login and password pairs. File format is similar to htpasswd files. Each line must be in form<username>:<bcrypt hash of password>
. Empty lines and lines starting with#
are ignored.hidden_domain
- same as instatic
providerreload
- interval for conditional password file reload, if it was modified since last load. Use negative duration to disable autoreload. Default:15s
.
cert
- use mutual TLS authentication with client certificates. In order to use this auth provider server must listen sockert in TLS mode (-cert
and-key
options) and client CA file must be specified (-cacert
). Example:cert://
.
