i just installed Ubuntu server 13.04. What services can i disable/uninstall? All i want is to keep sshd (to connect to my vps) and whatever is absolutely needed for the system to run and get rid of the rest. So far i have only uninstalled apache.
I want a minimal system to start from there and install only what i need.
