If you really, really have to use Facebook


That ominous feeling of being stalked, have you ever feel it? I have, oddly by an ad for gaming mouse sold by Lazada when I was reading news on a indonesian news site. The same ad popped somewhere else, and follow me around that day. How did that happen? Well it was actually Facebook, among…

fail2ban, ufw, and sshd with custom port on Ubuntu


One of the tool we can use to secure our Ubuntu box from incoming attacks, if we can’t establish a whitelist for incoming connection is fail2ban.
