Hi,
I'm reading Kerberos - The Definitive Guide[1] and it makes the
following comment:
And to make matters worse, some Unix systems map their own hostname
to 127.0.0.1 (the loopback IP address).
This makes me think that the local host name /shouldn't/ be included in
the 127.0.0.1 (or ::1) entry in the /etc/hosts file.
However, according to the Gentoo AMD64 Handbook[2], we are supposed to
add the local host name to the 127.0.0.1 (and ::1) entry in the
/etc/hosts file.
Will someone please explain why the Gentoo AMD64 Handbook ~> Gentoo (at
large) says to add the local host name to the 127.0.0.1 (or ::1) entry
in the /etc/hosts file? What was the thought process behind that?
Incidentally, adding the local host name to the 127.0.0.1 (or ::1) entry
in the /etc/hosts file causes "hostname -i" to return 127.0.0.1 instead
of the IP address bound to the network interface.
Thank you for any input you can provide.
