Hi,
So, /etc/hosts comes setup by default (i.e. after kickstart install)
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
I'm fairly certain to not too long ago (redhat-9 perhaps) the hostname
of the system was also added to the localhost entry:
127.0.0.1 my.host.com my localhost.localdomain localhost
This had the distinct advantage that when apps (i.e. yum-updatesd) sent
mail from the system via a mail host then address would appear as:
root at my.host.com instead of root at localhost.com
Am I remembering correctly, in terms of how I believe it used to be? If
so, anyone know why it changed?
Cheers,
Harry
