Hi Guys,
I have tried mining zcash through amazon aws (ubuntu) and after installation, I have tested my installations in 2 ways:
- $ ./qa/zcash/full-test-suite.sh
- $ ./qa/pull-tester/rpc-tests.sh
The first test which is: ./qa/zcash/full-test-suite.sh I got all pass and no failures. However, in the second test, which is: ./qa/pull-tester/rpc-tests.sh I got these errors (failures):
Tests completed: 21
successes 17; failures: 4
Failing tests: wallet_protectcoinbase.py wallet.py wallet_nullifiers.py zcjoinsplitdoublespend.py
By the way, I followed exactly this guide of Austin Williams: https://github.com/Austin-Williams/zcash-guides/wiki/Guide-to-Mining-Zcash-on-Amazon-EC2 and I am stuck at the testing steps because of the errors (failures) encountered above. Should I continue with the configuring miners step or need to fix first the errors above? If I need to fix them first, how? Please help as I am not really a tech guy.
Thank you very much and more power! 
Regards,
Jac
P.S.: If you have any tips about mitigating costs with amazon aws like how much shall I bid if I use the spot price, it is most welcomed! at the moment, I used the default pricing and will soon do the spot price if needed.
