inet.d

[Kevin Philp]

I have just installed a Ubuntu desktop (Dapper, 6.06). I then installed 
Apache2, Mysql, SSH, Postfix, NIS, NFS and Squid. When I checked inet.d I 
noticed that not a single service was included, the configuration file is 
completely empty.

So my questions are:

1. What services (from the list above) generally use inet.d and how do I set 
them up.

2. Why is inet.d installed if it isn't doing anything?
