I use xmr stak 2.4.2 via hiveos and some rigs cast xmr on windows 10.
on cast xmr 0.9.2 you need to have like this :
cast_xmr-vega -S communitypool.stellite.cash:6677 -u Se3wndc29KLiMZvVTDPTpETMekddsfdsfsameB7d9eokA5eFWmjBFeHirhUyfi26dLwduArwCVLCkFJcc9V2GXVFsedt -p gpu:cedricp@outlok.com -G 0,1,2 --algo=1 --ratewatchdog
For XMR_Stak like this in your pool.txts
"pool_list" :
[
{"pool_address" : "communitypool.stellite.cash:6677", "wallet_address" : "Se3wndc29KLiMZvVTDPTpETMekddsfdsfsameB7d9eokA5eFWmjBFeHirhUyfi26dLwduArwCVLCkFJcc9V2GXVFsedt", "rig_id" : "", "pool_password" : "cpu:cedricp@outlok.com", "use_nicehash" : false, "use_tls" : false, "tls_fingerprint" : "", "pool_weight" : 1 },
],
"currency" : "stellite",
