Any ideas?
Yes, but what commands to get the info?
Dashninja ?Any ideas?
Most likely. You would need a decent machine, the task is CPU bound.Okay, seems you're the author of the crawler. In essence, it prepares a payload and sends to all valid masternodes via nc, but only once a day per node. What if I wanted to do that every hour, too expensive?
To determine the dashd version number of a given masternode, you can use the following command in the Dash Core client:
dash-cli masternode status
Or, if you're checking remotely via the RPC interface, use:
dash-cli getnetworkinfo
The output will include the protocolversion field, which indicates the version of dashd that the masternode is running.
