Few days ago I've installed Ubuntu on at work. I cannot open folders under many directories because I don't have permissions. Then I gave permissions, with the terminal. And guess what? I has started to reset its static IP. I wanted to ad cron jobs, they didn't work, also you write them as text, I have no idea how they work. When you shut down Ubuntu from terminal the PC goes for sleep, it doesn't power off. You don't have administrative rights in your PC, you always need to open terminal and sudo su. There are some workarounds that they either don't work or breaks other things. You don't have wizards when installing a software, you need to study the manuals and then sudo su in to the terminal to configure the files, and then you have to learn how to write a file from terminal. If you are lucky it works. Do you know how to enter Google Public DNS IPs to the settings? You have to ask it to your friend. Tip: use comma. It is good for servers because it is free. However not so much user friendly for desktop users. Thanks for making it guys. It is second best OS, after FreeBSD.
