--upstream-auth UPSTREAM_AUTH

Proxy Authentication: username:password

--keepserving

Continue serving after client playback or file read. We exit by default.

-d, --detail

Increase flow detail display level. Can be passed multiple times.

Proxy Modes:¶

-R REVERSE_PROXY, --reverse REVERSE_PROXY

Forward all requests to upstream HTTP server: http[s]://host[:port]. Clients can always connect both via HTTPS and HTTP, the connection to the server is determined by the specified scheme.

--socks

Set SOCKS5 proxy mode.

-T, --transparent

Set transparent proxy mode.

-U UPSTREAM_PROXY, --upstream UPSTREAM_PROXY

Forward all requests to upstream proxy server: http://host[:port]

Proxy Options:¶

-b ADDR, --bind-address ADDR

Address to bind proxy to (defaults to all interfaces).

-I HOST, --ignore HOST

Ignore host and forward all traffic without processing it. In transparent mode, it is recommended to use an IP address (range), not the hostname. In regular mode, only SSL traffic is ignored and the hostname should be used. The supplied value is interpreted as a regular expression and matched on the ip or the hostname. Can be passed multiple times.

--tcp HOST

Generic TCP SSL proxy mode for all hosts that match the pattern. Similar to --ignore, but SSL connections are intercepted. The communication contents are printed to the log in verbose mode.

-n, --no-server

Don't start a proxy server.

-p PORT, --port PORT

Proxy service port.

--no-http2

Explicitly disable HTTP/2 support. If your OpenSSL version supports ALPN, HTTP/2 is enabled by default.

--raw-tcp | --no-raw-tcp

Explicitly enable/disable experimental raw tcp support. Disabled by default. Default value will change in a future version.

--websockets | --no-websockets

Explicitly enable/disable experimental WebSocket support. Disabled by default as messages are only printed to the event log and not retained. Default value will change in a future version.

--spoof-source-address

Use the client's IP for server-side connections.

SSL:¶

--cert SPEC

Add an SSL certificate. SPEC is of the form "[domain=]path". The domain may include a wildcard, and is equal to "*" if not specified. The file at path is a certificate in PEM format. If a private key is included in the PEM, it is used, otherwise the default key in the conf dir is used. The PEM file should contain the full certificate chain, with the leaf certificate as the first entry. Can be passed multiple times.

--ciphers-client CIPHERS_CLIENT

Set supported ciphers for client connections. (OpenSSL Syntax)

--ciphers-server CIPHERS_SERVER

Set supported ciphers for server connections. (OpenSSL Syntax)

--client-certs CLIENT_CERTS

Client certificate file or directory.

--no-upstream-cert

Don't connect to upstream server to look up certificate details.

--add-upstream-certs-to-client-chain

Add all certificates of the upstream server to the certificate chain that will be served to the proxy client, as extras.

--insecure

Do not verify upstream server SSL/TLS certificates.

--upstream-trusted-cadir CA_DIR

Path to a directory of trusted CA certificates for upstream server verification prepared using the c_rehash tool.

--upstream-trusted-ca CA_CERT

Path to a PEM formatted trusted CA certificate.

--ssl-version-client {all|TLSv1_2|secure|TLSv1_1|TLSv1|SSLv3|SSLv2}

Set supported SSL/TLS versions for client connections. SSLv2, SSLv3 and all are INSECURE. Defaults to secure, which is TLS1.0+.

--ssl-version-server {all|TLSv1_2|secure|TLSv1_1|TLSv1|SSLv3|SSLv2}

Set supported SSL/TLS versions for server connections. SSLv2, SSLv3 and all are INSECURE. Defaults to secure, which is TLS1.0+.

Onboarding App:¶

--noapp

Disable the mitmproxy onboarding app.

--app-host HOST

Domain to serve the onboarding app from. For transparent mode, use an IP when a DNS entry for the app domain is not present. (Default: mitm.it)

--app-port PORT

Port to serve the onboarding app from. (Default: 80)

-c PATH, --client-replay PATH

Replay client requests from a saved file.

Server Replay:¶

-S PATH, --server-replay PATH

-k, --replay-kill-extra

--server-replay-use-header HEADER

Request header to be considered during replay. Can be passed multiple times.

--norefresh

Disable response refresh, which updates times in cookies and headers for replayed responses.

--no-pop

Disable response pop from response flow. This makes it possible to replay same response multiple times.

--replay-ignore-content

Ignore request's content while searching for a saved flow to replay.

--replay-ignore-payload-param PARAM

Request's payload parameter (application/x-www-form-urlencoded or multipart/form-data) to be ignored while searching for a saved flow to replay. Can be passed multiple times.

--replay-ignore-param PARAM
