## 演示

你可以在几分钟内运行自己的演示服务器（旧的 Heroku 演示已随 Heroku 免费套餐的取消而消失）。[`example/fly.toml`](https://github.com/jpillora/chisel/blob/HEAD/example/fly.toml) 可将此 `chisel server` 部署到 [fly.io](https://fly.io) 的免费额度：```sh
$ chisel server --port $PORT --backend http://example.com
# listens on $PORT, proxies normal web requests to http://example.com

在浏览器中访问应用的 URL 时，会命中服务器的默认后端代理，并显示 [example.com](http://example.com) 的副本。

--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 falls back to port 8080).

--key, (deprecated use --keygen and --keyfile instead)
An optional string to seed the generation of a ECDSA public
and private key pair. All communications 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).

--keygen, A path to write a newly generated PEM-encoded SSH private key file.
If users depend on your --key fingerprint, you may also include your --key to
output your existing key. Use - (dash) to output the generated key to stdout.

--keyfile, An optional path to a PEM-encoded SSH private key. When
this flag is set, the --key option is ignored, and the provided private key
is used to secure all communications. (defaults to the CHISEL_KEY_FILE
environment variable). Since ECDSA keys are short, you may also set keyfile
to the inline key string itself, exactly as printed by --keygen (a base64
string with a "ck-" prefix); no extra base64 encoding is needed.

--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. Patterns are NOT
anchored by default: "10.0.0.1:80" also matches
"210.0.0.1:8080", and "." matches any character. Anchor your
patterns, e.g. "^10\.0\.0\.1:80$". The empty string ""
matches every address. Addresses will
always come in the form "<remote-host>:<remote-port>" for normal remotes,
"R:<local-interface>:<local-port>" for reverse port forwarding
remotes, and "socks" for SOCKS5 proxy access. Note that SOCKS5
access previously bypassed this list; existing authfiles which
should allow SOCKS5 must add an entry matching "socks" (the
empty wildcard "" matches everything, including "socks"). This
file will be automatically reloaded on change. Reloads apply
to new connections and to new tunnels of connected clients;
established tunnels are not interrupted.

--auth, An optional string representing a single user with full
access, in the form of <user:pass>. It is equivalent to creating an
authfile with {"<user:pass>": [""]}. If unset, it will use the
environment variable AUTH.

--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 '5s' or '2m'. Defaults
to '25s' (set to 0s to disable).

--backend, Specifies another HTTP server to proxy requests to when
chisel receives a normal HTTP request. Useful for hiding chisel in
plain sight. --proxy is accepted as an alias for this flag.

--socks5, Allow clients to access the internal SOCKS5 proxy. See
chisel client --help for more information.

--reverse, Allow clients to specify reverse port forwarding remotes
in addition to normal remotes.

--tls-key, Enables TLS and provides optional path to a PEM-encoded
TLS private key. When this flag is set, you must also set --tls-cert,
and you cannot set --tls-domain.

--tls-cert, Enables TLS and provides optional path to a PEM-encoded
TLS certificate. When this flag is set, you must also set --tls-key,
and you cannot set --tls-domain.

--tls-domain, Enables TLS and automatically acquires a TLS key and
certificate using LetsEncrypt. Setting --tls-domain requires port 443.
You may specify multiple --tls-domain flags to serve multiple domains.
The resulting files are cached in the "$HOME/.cache/chisel" directory.
You can modify this path by setting the CHISEL_LE_CACHE variable,
or disable caching by setting this variable to "-". You can optionally
provide a certificate notification email by setting CHISEL_LE_EMAIL.

--tls-ca, a path to a PEM encoded CA certificate bundle or a directory
holding multiple PEM encode CA certificate bundle files, which is used to 
validate client connections. The provided CA certificates will be used 
instead of the system roots. This is commonly used to implement mutual-TLS. 

--pid Generate pid file in current working directory

<!--tmpl,code=plain:echo "$ chisel client --help" && go run main.go client --help | sed 's#0.0.0-src (go1\..*)#X.Y.Z#' -->``` plain 
$ chisel client --help

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

  <server> is the URL to the chisel server.

  <remote>s are remote connections tunneled through the server, each of
  which come in the form:

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

    ■ local-host defaults to 0.0.0.0 (all interfaces).
    ■ local-port defaults to remote-port.
    ■ remote-port is required*.
    ■ remote-host defaults to 127.0.0.1 (server localhost).
    ■ protocol defaults to tcp.

  which shares <remote-host>:<remote-port> from the server to the client
  as <local-host>:<local-port>, or:

    R:<local-interface>:<local-port>:<remote-host>:<remote-port>/<protocol>

  which does reverse port forwarding, sharing <remote-host>:<remote-port>
  from the client to the server's <local-interface>:<local-port>.

    example remotes

      3000
      example.com:3000
      3000:google.com:80
      192.168.0.5:3000:google.com:80
      socks
      5000:socks
      R:2222:localhost:22
      R:socks
      R:5000:socks
      stdio:example.com:22
      1.1.1.1:53/udp

    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. When the server also
    has --authfile set, SOCKS5 access requires an entry matching
    the token "socks" in the user's address list.

    When the chisel server has --reverse enabled, remotes can
    be prefixed with R to denote that they are reversed. That
    is, the server will listen and accept connections, and they
    will be proxied through the client which specified the remote.
    Reverse remotes specifying "R:socks" will listen on the server's
    default socks port (1080) and terminate the connection at the
    client's internal SOCKS5 proxy.

    When stdio is used as local-host, the tunnel will connect standard
    input/output of this program with the remote. This is useful when 
    combined with ssh ProxyCommand. You can use
      ssh -o ProxyCommand='chisel client chiselserver stdio:%h:%p' \
          [email protected]
    to connect to an SSH server through the tunnel.

  Options:

    --fingerprint, A *strongly recommended* fingerprint string
    to perform host-key validation against the server's public key.
    Fingerprint mismatches will close the connection.
    Fingerprints are generated by hashing the ECDSA public key using
    SHA256 and encoding the result in base64.
    Fingerprints must be 44 characters containing a trailing equals (=).
    Legacy MD5 colon fingerprints (deprecated) are still accepted,
    but only in their full 16-octet form; truncated prefixes are
    rejected.

    --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 '5s' or '2m'. Defaults
    to '25s' (set to 0s to disable).

    --max-retry-count, Maximum number of times to retry before exiting.
    Defaults to unlimited.

    --min-retry-interval, Minimum wait time before retrying after a
    disconnection. Defaults to 1 second.

    --max-retry-interval, Maximum wait time before retrying after a
    disconnection. Defaults to 5 minutes.

    --proxy, An optional HTTP CONNECT or SOCKS5 proxy which will be
    used to reach the chisel server. Authentication can be specified
    inside the URL. Credentials must be URL-encoded; for example a
    "#" in the password must be written as "%23".
    For example, http://admin:[email protected]:8081
            or: socks://admin:[email protected]:1080
    The socks://, socks5:// and socks5h:// schemes are equivalent:
    DNS is always resolved by the proxy.

    --header, Set a custom header in the form "HeaderName: HeaderContent".
    Can be used multiple times. (e.g --header "Foo: Bar" --header "Hello: World")

    --hostname, Optionally set the 'Host' header (defaults to the host
    found in the server url).

    --sni, Override the ServerName when using TLS (defaults to the 
    hostname).

    --tls-ca, An optional root certificate bundle used to verify the
    chisel server. Only valid when connecting to the server with
    "https" or "wss". By default, the operating system CAs will be used.

    --tls-skip-verify, Skip server TLS certificate verification of
    chain and host name (if TLS is used for transport connections to
    server). If set, client accepts any TLS certificate presented by
    the server and any host name in that certificate. This only affects
    transport https (wss) connection. Chisel server's public key
    may be still verified (see --fingerprint) after inner connection
    is established.

    --tls-key, a path to a PEM encoded private key used for client 
    authentication (mutual-TLS).

    --tls-cert, a path to a PEM encoded certificate matching the provided 
    private key. The certificate must have client authentication 
    enabled (mutual-TLS).

    --pid Generate pid file in current working directory

    -v, Enable verbose logging

    --help, This help text

  Signals:
    The chisel process is listening for:
      a SIGINT or SIGTERM to begin a graceful shutdown
        (a second signal forces an immediate exit),
      a SIGUSR2 to print process stats, and
      a SIGHUP to short-circuit the client reconnect timer
