We have a mining co-op. For now we are all on the same sub-net and when MM is running on it I see all the devices on the network. We all have different sub IP ranges, i.e. ( 192.168.1.30 to 192.168.1.50 ) for one person.
That makes sense. However, the S3s will not show up in MultiMiner unless they are manually configured to allow the IP address of the PC MultiMiner is running on. In other words, someone must have already configured these S3s to allow either
your IP or
every IP on the network access (using steps such as
these).
One option would be changing / undoing that configuration. If those S3s really do belong to other folks they should probably not be configured so that your IP address has access to them.
That being said, the next update to MultiMiner will allow the user to hide individual Network Devices that they do not wish to monitor.
