Default to disabling all inetd.conf entries, in particular, telnetd and ftpd. This more conservative default reduces the exposure of freshly installed machines, which is especially valuable for machines that receive minimal further configuration before being put into production. Generally speaking, SSH has superseded the use of both telnet and ftp in many environments. In light of recent remotely exploitable security holes in both telnetd and ftpd, this choice retains flexibility (both telnetd and ftpd daemons remain installed and easily enableable) while protecting users who don't need the additional risk. This change brings our configuration into line with the majority of other UNIX vendors, including OpenBSD and NetBSD. To address the concerns of those requiring remote access via telnet from first install, changes will shortly be committed to sysinstall to provide the ability to edit inetd.conf during the installation process, allowing telnetd and ftp to be re-enabled during the installation process. While I'm at it, slightly improve commenting for inetd.conf so that it's more clear to users how to enable and disable services. Further commenting to indicate the functions of various columns would probably also be useful. Reviewed by: imp, chris, jake, nate, -arch, -stable

The kerberised network services should only be active in inetd.conf if kerberos is installed. So far as I'm aware, kerberos aware clients detect ECONNREFUSED and (if allowed) fall back to the non-kerberos servers. They do not know how to interpret messages such as "rlogind: unknown option -k". I believe Garrett also mentioned this. Unfortunately, this adds an extra step to bringing up kerberos. It also stops /var/log/messages getting quite so many useless (and confusing) error messages when somebody does a port scan on you.
