Firstly open up the rc file for your inetd (e.g. /etc/inetd.conf) and
comment out any lines you don't need. This should do (at least)
discard, echo, daytime.
Then, determine which programs are responsible for the remaining open
ports. Stop them from running and prevent them from starting by
default if necessary. How to do this varies on an
application-to-application basis; but can probably be forced by
removing the package in question (if you aren't using it at all) or
using update-rc.d (I think).
If a port is open, and associated with a program which isn't from a
debian package and you don't believe you put it there yourself - its
time to consider the possibility your machine has been compromised.
