admin Namespace

The admin API allows you to configure your node, including adding and removing peers.

Note

As this namespace can configure your node at runtime, it is generally not advised to expose it publicly.

admin_addPeer

Add the given peer to the current peer set of the node.

The method accepts a single argument, the enode URL of the remote peer to connect to, and returns a bool indicating whether the peer was accepted or not.

Example

// > {"jsonrpc":"2.0","id":1,"method":"admin_addPeer","params":["enode://a979fb575495b8d6db44f750317d0f4622bf4c2aa3365d6af7c284339968eef29b69ad0dce72a4d8db5ebb4968de0e3bec910127f134779fbcb0cb6d3331163c@52.16.188.185:30303"]}
{"jsonrpc":"2.0","id":1,"result":true}

admin_removePeer

Disconnects from a peer if the connection exists. Returns a bool indicating whether the peer was successfully removed or not.

Example

// > {"jsonrpc":"2.0","id":1,"method":"admin_removePeer","params":["enode://a979fb575495b8d6db44f750317d0f4622bf4c2aa3365d6af7c284339968eef29b69ad0dce72a4d8db5ebb4968de0e3bec910127f134779fbcb0cb6d3331163c@52.16.188.185:30303"]}
{"jsonrpc":"2.0","id":1,"result":true}

admin_addTrustedPeer

Adds the given peer to a list of trusted peers, which allows the peer to always connect, even if there would be no room for it otherwise.

It returns a bool indicating whether the peer was added to the list or not.

Example

// > {"jsonrpc":"2.0","id":1,"method":"admin_addTrustedPeer","params":["enode://a979fb575495b8d6db44f750317d0f4622bf4c2aa3365d6af7c284339968eef29b69ad0dce72a4d8db5ebb4968de0e3bec910127f134779fbcb0cb6d3331163c@52.16.188.185:30303"]}
{"jsonrpc":"2.0","id":1,"result":true}

admin_removeTrustedPeer

Removes a remote node from the trusted peer set, but it does not disconnect it automatically.

Returns true if the peer was successfully removed.

Example

// > {"jsonrpc":"2.0","id":1,"method":"admin_removeTrustedPeer","params":["enode://a979fb575495b8d6db44f750317d0f4622bf4c2aa3365d6af7c284339968eef29b69ad0dce72a4d8db5ebb4968de0e3bec910127f134779fbcb0cb6d3331163c@52.16.188.185:30303"]}
{"jsonrpc":"2.0","id":1,"result":true}

admin_nodeInfo

Returns all information known about the running node.

These include general information about the node itself, as well as what protocols it participates in, its IP and ports.

Example

// > {"jsonrpc":"2.0","id":1,"method":"admin_nodeInfo","params":[]}

    "result": {

}

admin_peerEvents, admin_peerEvents_unsubscribe

Subscribe to events received by peers over the network.

Like other subscription methods, this returns the ID of the subscription, which is then used in all events subsequently.

To unsubscribe from peer events, call admin_peerEvents_unsubscribe

Example

// > {"jsonrpc":"2.0","id":1,"method":"admin_peerEvents","params":[]}
// responds with subscription ID
{"jsonrpc": "2.0", "id": 1, "result": "0xcd0c3e8af590364c09d0fa6a1210faf5"}
