Running a node with dhtnode

dhtnode is a command-line utility included with OpenDHT to run, control and monitor an OpenDHT node.

Running dhtnode

dhtnode [-p local_port] [-b bootstrap_host:port] [-i] [-v]

• -b allows to specify a bootstrap node address.
• -p allows to specify the local UDP port to bind (optional).
• -i will generate a DHT "identity" with the node (RSA key pair, and certificate published on the DHT). Required to perform cryptographic operations (encrypt/sign values).
• -v will enable debug logs for OpenDHT to standard output.

for instance:

dhtnode -b bootstrap.ring.cx:4222 will run a node and use bootstrap.ring.cx port 4222 as a bootstrap node.
