You can refine exactly what services people have access to on your machine in more detail by selecting Yes to the question about selecting services to enable.
The services are explained by Lokkit as you go through the choices. Currently you can select from:
This is not needed for you to view pages on other machines or for you to view or edit pages on your own machine. It is only necessary if you want other people to be able to view webpages on your machine.
If email arrives straight onto your machine, you will need this. If email arrives on your ISP's server and you collect it over IMAP or POP3 or with a tool such as fetchmail, you do not need to enable this.
If you have secure shell -- ssh -- installed on your machine, you will want to enable this. It is possible to configure this even more tightly by creating a list of hosts which are allowed to connect to your machine via ssh. Lokkit will not do this for you, but you can find the details in the documentation for ssh: typically in either the manual page (man ssh) or in the files in the /usr/doc/ssh directory.
Until recently, few distributions shipped this program because of export restrictions. Since the end of the year 1999, however, several distributions have begun carrying it. If you have a recent installation, you may find it is already installed. Other people will have to install the package themselves.
The telnet command is a very common tool but it does have security problems, because people can listen in to it. If you are very very paranoid, or never log in to your home machine from outside, you may want to consider turning it off altogether, especially if you have ssh installed.
