Prerequisites

For running the Hacker Challenge you need a VM with Intel processor that supports SGX1/2, check supported processors. You may also rent a VM, see RedSwitches or Hetzner. Public IP is not mandatory to participate.

Make sure you enabled SGX in BIOS. Just do cpuid | grep -i sgx to see if SGX is enabled.
Make sure you also have kernel above v5.13 to get a built-in SGX DCAP driver.
Final step is to add the symlinks for the sgx devices:

sudo mkdir -p /dev/sgx
sudo ln -sf ../sgx_enclave /dev/sgx/enclave
sudo ln -sf ../sgx_provision /dev/sgx/provision
