NGHTTPD(1) nghttp2 NGHTTPD(1) NAME nghttpd - HTTP/2 server SYNOPSIS nghttpd [OPTION]... <PORT> [<PRIVATE_KEY> <CERT>] DESCRIPTION HTTP/2 server <PORT> Specify listening port number. <PRIVATE_KEY> Set path to server's private key. Required unless --no-tls is specified. <CERT> Set path to server's certificate. Required unless --no-tls is specified. OPTIONS -a, --address=<ADDR> The address to bind to. If not specified the default IP address determined by getaddrinfo is used. -D, --daemon Run in a background. If -D is used, the current working direc- tory is changed to '/'. Therefore if this option is used, -d option must be specified. -V, --verify-client The server sends a client certificate request. If the client did not return a certificate, the handshake is terminated. Currently, this option just requests a client certificate and does not verify it. -d, --htdocs=<PATH> Specify document root. If this option is not specified, the document root is the current working directory. -v, --verbose Print debug information such as reception/ transmission of frames and name/value pairs. --no-tls Disable SSL/TLS. -c, --header-table-size=<SIZE> Specify decoder header table size. --encoder-header-table-size=<SIZE> Specify encoder header table size. The decoder (client) speci- fies the maximum dynamic table size it accepts. Then the negotiated dynamic table size is the minimum of this option value and the value which client specified. --color Force colored log output. -p, --push=<PATH>=<PUSH_PATH,...> Push resources <PUSH_PATH>s when <PATH> is requested. This option can be used repeatedly to specify multiple push con- figurations. <PATH> and <PUSH_PATH>s are relative to document root. See --htdocs option. Example: -p/=/foo.png -p/doc=/bar.css -b, --padding=<N> Add at most <N> bytes to a frame payload as padding. Spec- ify 0 to disable padding. -m, --max-concurrent-streams=<N> Set the maximum number of the concurrent streams in one HTTP/2 session. Default: 100 -n, --workers=<N> Set the number of worker threads. Default: 1 -e, --error-gzip Make error response gzipped. -w, --window-bits=<N> Sets the stream level initial window size to 2**<N>-1. -W, --connection-window-bits=<N> Sets the connection level initial window size to 2**<N>-1. --dh-param-file=<PATH> Path to file that contains DH parameters in PEM format. With- out this option, DHE cipher suites are not available. --early-response Start sending response when request HEADERS is received, rather than complete request is received. --trailer=<HEADER> Add a trailer header to a response. <HEADER> must not include pseudo header field (header field name starting with ':'). The trailer is sent only if a response has body part. Example: --trailer 'foo: bar'. --hexdump Display the incoming traffic in hexadecimal (Canonical hex+ASCII display). If SSL/TLS is used, decrypted data are used. --echo-upload Send back uploaded content if method is POST or PUT. --mime-types-file=<PATH> Path to file that contains MIME media types and the exten- sions that represent them. Default: /etc/mime.types --no-content-length Don't send content-length header field. --ktls Enable ktls. --version Display version information and exit. -h, --help Display this help and exit. The <SIZE> argument is an integer and an optional unit (e.g., 10K is 10 * 1024). Units are K, M and G (powers of 1024).
