# `reth p2p` P2P Debugging utilities ```bash $ reth p2p --help Usage: reth p2p [OPTIONS] Commands: header Download block header body Download block body help Print this message or the help of the given subcommand(s) Options: --config The path to the configuration file to use. --chain The chain this node is running. Possible values are either a built-in chain or the path to a chain specification file. Built-in chains: mainnet, sepolia, goerli, holesky, dev [default: mainnet] --datadir The path to the data dir for all reth files and subdirectories. Defaults to the OS-specific data directory: - Linux: `$XDG_DATA_HOME/reth/` or `$HOME/.local/share/reth/` - Windows: `{FOLDERID_RoamingAppData}/reth/` - macOS: `$HOME/Library/Application Support/reth/` [default: default] --p2p-secret-key Secret key to use for this node. This also will deterministically set the peer ID. -d, --disable-discovery Disable the discovery service --disable-dns-discovery Disable the DNS discovery --disable-discv4-discovery Disable Discv4 discovery --discovery.addr The UDP address to use for P2P discovery/networking [default: 0.0.0.0] --discovery.port The UDP port to use for P2P discovery/networking [default: 30303] --trusted-peer Target trusted peer --trusted-only Connect only to trusted peers --instance Add a new instance of a node. Configures the ports of the node to avoid conflicts with the defaults. This is useful for running multiple nodes on the same machine. Max number of instances is 200. It is chosen in a way so that it's not possible to have port numbers that conflict with each other. Changes to the following port numbers: - DISCOVERY_PORT: default + `instance` - 1 - AUTH_PORT: default + `instance` * 100 - 100 - HTTP_RPC_PORT: default - `instance` + 1 - WS_RPC_PORT: default + `instance` * 2 - 2 [default: 1] --retries The number of retries per request [default: 5] --nat [default: any] -h, --help Print help (see a summary with '-h') Database: --db.log-level Database logging level. Levels higher than "notice" require a debug build Possible values: - fatal: Enables logging for critical conditions, i.e. assertion failures - error: Enables logging for error conditions - warn: Enables logging for warning conditions - notice: Enables logging for normal but significant condition - verbose: Enables logging for verbose informational - debug: Enables logging for debug-level messages - trace: Enables logging for trace debug-level messages - extra: Enables logging for extra debug-level messages Logging: --log.file.directory The path to put log files in [default: /reth/logs] --log.file.max-size The maximum size (in MB) of one log file [default: 200] --log.file.max-files The maximum amount of log files that will be stored. If set to 0, background file logging is disabled [default: 5] --log.file.filter The filter to use for logs written to the log file [default: debug] --log.journald Write logs to journald --log.journald.filter The filter to use for logs written to journald [default: error] --color Sets whether or not the formatter emits ANSI terminal escape codes for colors and other text formatting [default: always] Possible values: - always: Colors on - auto: Colors on - never: Colors off Display: -v, --verbosity... Set the minimum log level. -v Errors -vv Warnings -vvv Info -vvvv Debug -vvvvv Traces (warning: very verbose!) -q, --quiet Silence all log output ``` ## `reth p2p body` Download block body ```bash $ reth p2p body --help Usage: reth p2p body [OPTIONS] Arguments: The block number or hash Options: --instance Add a new instance of a node.
