chisel v1.8.1 releases: A fast TCP tunnel over HTTP

$ chisel server --help



  Usage: chisel server [options]



  Options:



    --host, Defines the HTTP listening host – the network interface

    (defaults the environment variable HOST and falls back to 0.0.0.0).



    --port, -p, Defines the HTTP listening port (defaults to the environment

    variable PORT and fallsback to port 8080).



    --key, An optional string to seed the generation of a ECDSA public

    and private key pair. All commications will be secured using this

    key pair. Share the subsequent fingerprint with clients to enable detection

    of man-in-the-middle attacks (defaults to the CHISEL_KEY environment

    variable, otherwise a new key is generate each run).



    --authfile, An optional path to a users.json file. This file should

    be an object with users defined like:

      {

        "<user:pass>": ["<addr-regex>","<addr-regex>"]

      }

    when <user> connects, their <pass> will be verified and then

    each of the remote addresses will be compared against the list

    of address regular expressions for a match. Addresses will

    always come in the form "<host/ip>:<port>".



    --auth, An optional string representing a single user with full

    access, in the form of <user:pass>. This is equivalent to creating an

    authfile with {"<user:pass>": [""]}.



    --proxy, Specifies another HTTP server to proxy requests to when

    chisel receives a normal HTTP request. Useful for hiding chisel in

    plain sight.



    --socks5, Allows client to access the internal SOCKS5 proxy. See

    chisel client --help for more information.



    --pid Generate pid file in current directory



    -v, Enable verbose logging

$ chisel client --help



  Usage: chisel client [options] <server> <remote> [remote] [remote] ...



  <server> is the URL to the chisel server.



  <remote>s are remote connections tunnelled through the server, each of

  which come in the form:



    <local-host>:<local-port>:<remote-host>:<remote-port>



    ■ local-host defaults to 0.0.0.0 (all interfaces).

    ■ local-port defaults to remote-port.

    ■ remote-port is required*.

    ■ remote-host defaults to 0.0.0.0 (server localhost).



    example remotes



      3000

      example.com:3000

      3000:google.com:80

      192.168.0.5:3000:google.com:80

      socks

      5000:socks



    *When the chisel server has --socks5 enabled, remotes can

    specify "socks" in place of remote-host and remote-port.

    The default local host and port for a "socks" remote is

    127.0.0.1:1080. Connections to this remote will terminate

    at the server's internal SOCKS5 proxy.



  Options:



    --fingerprint, A *strongly recommended* fingerprint string

    to perform host-key validation against the server's public key.

    You may provide just a prefix of the key or the entire string.

    Fingerprint mismatches will close the connection.



    --auth, An optional username and password (client authentication)

    in the form: "<user>:<pass>". These credentials are compared to

    the credentials inside the server's --authfile. defaults to the

    AUTH environment variable.



    --keepalive, An optional keepalive interval. Since the underlying

    transport is HTTP, in many instances we'll be traversing through

    proxies, often these proxies will close idle connections. You must

    specify a time with a unit, for example '30s' or '2m'. Defaults

    to '0s' (disabled).



    --proxy, An optional HTTP CONNECT proxy which will be used reach

    the chisel server. Authentication can be specified inside the URL.

    For example, http://admin:password@my-server.com:8081



    --pid Generate pid file in current directory



    -v, Enable verbose logging
