addnode (4.1.2 RPC)

addnode "node" "command"

Attempts to add or remove a node from the addnode list.
Or try a connection to a node once.
Nodes added using addnode (or -connect) are protected from DoS disconnection and are not required to be
full nodes/support SegWit as other outbound peers are (though such peers will not be synced from).

Arguments:
1. node       (string, required) The node (see getpeerinfo for nodes)
2. command    (string, required) 'add' to add a node to the list, 'remove' to remove a node from the list, 'onetry' to try a connection to the node once

Examples:
> syscoin-cli addnode "192.168.0.6:8369" "onetry"
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "addnode", "params": ["192.168.0.6:8369", "onetry"] }' -H 'content-type: text/plain;' http://127.0.0.1:8370/
