Hello @fabiodc 👋 Welcome to the 
HIVE social blockchain. I saw your post in the latest #heyhaveyamet ( #hhym ) post and decided to drop in for a visit. I see that you are "a student of network administration and computer security". Amongst many other jobs that I have done over the years, I used to be a network admin for a while, but I am now retired. I hope you enjoy your time here on the social blockchain.
thank you very much for the welcome, I hope to be able to contribute a lot to the hive community.
