Description

We descovered that we got an error message during Wazuh manager installation in Ubuntu 18.

Can't load /root/.rnd into RNG
139871618495552:error:2406F079:random number generator:RAND_load_file:Cannot open file:../crypto/rand/randfile.c:88:Filename=/root/.rnd

The error is due OpenSSL version, concretly v1.1.1. This error is fixed by OpenSSL in v1.1.1a.

Despite de error message, OpenSSL works well. It generates diferent keys and certificates values, so we have just ignored the error message.

At /wazuh/src/init/ we have changed GenerateAuthCert function at inst-functions.sh file, adding 2>/dev/null when the key and certicate is created.

Logs/Alerts example

As we can see in the next picture, we have de error message.
