kresctl(8) Knot Resolver 6.1.0 kresctl(8) NAME kresctl - Control Knot Resolver 6.1.0, the full caching DNSSEC-enabled re- solver SYNOPSIS kresctl [-s|--socket API_SOCKET] <command> <args> DESCRIPTION kresctl is a control tool for Knot Resolver, a DNSSEC-enabled full caching resolver. kresctl may be used to control and inspect the configuration of running Knot Resolver via its HTTP API. Full documentation is available at https://www.knot-resolver.cz/documenta- tion/latest/ or in package documentation (available as knot-resolver-doc package in most distributions. OPTIONS The available options are: -s <api_socket>, --socket <api_socket> Specify how to connect to a running Knot Resolver. Accepts path to Unix-domain socket or host:port. Defaults to /var/run/knot-re- solver/kres-api.sock Some commands do not require communication with the running re- solver. In such cases, the value of this option is ignored and the command may succeed even if the socket is invalid. -h, --help Print help message and exit. COMMANDS config [-d|--delete] [--stdin] json_ptr [new_value] Get or modify resolver's runtime configuration. json_ptr follows RFC 6901 and specifies, which part of the configu- ration will the tool operate on. This argument is required. When not given any additional options or arguments, prints the current con- figured value. Equivalent to GET method in the underlying HTTP API. When -d or --delete is provided, kresctl tries to remove the runtime configuration subtree. The operation fails if it renders the config- uration invalid. Equivalent to the DELETE method in the HTTP API. When --stdin or new_value are provided, the new value (from the ar- gument or from reading stdin) is put into the configuration at the given json_ptr. The operation fails if it renders the configuration invalid. Equivalent to PUT method in the underlying HTTP API. stop Gracefully stops the running resolver.
