Overview
Linux applications use entropy to generate random numbers for objects such as IDs or SSL traffic. These operations wait until there is enough entropy to complete the task. Without enough entropy, the kernel is not able to generate these random numbers with sufficient speed, which can lead to timeouts and the refusal of secure connections. To check available entropy:
