Auto-generated documentation.

Description

Crawl a network on the devp2p layer and generate a nodes JSON file.

polycli p2p crawl [nodes file] [flags]

Usage

To crawl the network for nodes and write the output json to a file. This will not engage in block or transaction propagation, but it can give a good indicator of network size, and the output json can be used to quick start other nodes.

Example

polycli p2p crawl nodes.json \
  --bootnodes "enode://0cb82b395094ee4a2915e9714894627de9ed8498fb881cec6db7c65e8b9a5bd7f2f25cc84e71e89d0947e51c76e85d0847de848c7782b13c0255247a6758178c@44.232.55.71:30303,enode://88116f4295f5a31538ae409e4d44ad40d22e44ee9342869e7d68bdec55b0f83c1530355ce8b41fbec0928a7d75a5745d528450d30aec92066ab6ba1ee351d710@159.203.9.164:30303,enode://4be7248c3a12c5f95d4ef5fff37f7c44ad1072fdb59701b2e5987c5f3846ef448ce7eabc941c5575b13db0fb016552c1fa5cca0dda1a8008cf6d63874c0f3eb7@3.93.224.197:30303,enode://32dd20eaf75513cf84ffc9940972ab17a62e88ea753b0780ea5eca9f40f9254064dacb99508337043d944c2a41b561a17deaad45c53ea0be02663e55e6a302b2@3.212.183.151:30303" \
  --network-id 137

Flags

  -b, --bootnodes string               comma separated nodes used for bootstrapping. At least one bootnode is
                                       required, so other nodes in the network can discover each other
  -d, --database string                node database for updating and storing client information
      --discovery-dns string           enable EIP-1459, DNS Discovery to recover node list from given ENRTree
  -h, --help                           help for crawl
  -n, --network-id uint                filter discovered nodes by this network ID
  -u, --only-urls                      only writes enode URLs to output (default true)
  -p, --parallel int                   how many parallel discoveries to attempt (default 16)
  -r, --revalidation-interval string   time before retrying to connect to a failed peer (default "10m")
  -t, --timeout string                 time limit for the crawl (default "30m0s")
