EthOS is Linux based and uses the Claymore Ethereum miner. Awesome Miner can connect to any Claymore Ethereum miner as an External Miner if the API of the Claymore Ethereum miner is enabled.

To enable the API of Claymore Ethereum miner, make sure the mining process on EthOS is started with the command line argument: -mport 3333

The same concept is applicable for HiveOS. If the mining software running on HiveOS is running with API enabled, Awesome Miner can monitor it as an External Miner.
