This is something that for a Linux user is extremly importatnt. At some point you will need to generate your own cert, let's say for a secure RSYNC between two machines.
In this tutorial I will show how easy it is to get a self signed cert, just follow the instruction and in few minuts you will have a cert of your own.
Log in to your Linux Sever and type this command in:
openssl req -new -x509 -days 365 -nodes -out server.crt -keyout server.key
See ya next time.
