This did not work for me.
in /etc/hosts I put
----------------
#dhcp dynamic entry marygrace
192.168.1.3 jillestial.home.network jillestial
192.168.1.6 siway.home.network siway
#dhcp dynamic entry sidell
---------------------
at the bottom of dhcpcd.exe I put
------------------
# ==== Put your code for the case interface has been
shut down here
# ==== End
;;
esac
# Update the hosts file
/usr/local/bin/fixhostsfile 2>&1 | logger -t "dhcpcd"
&
exit 0
--------------------
I copied /usr/local/bin/fixhostsfile and made chmod
755 with my domain name hard coded in
------------------
IDSTRING="#dhcp dynamic entry"
HOSTNAME=`hostname|awk -F. '{print $1}'`
DOMAINNAME=`home.network`
#HOSTENTRY="`ypcat hosts|grep ^$IPADDR|uniq`
$HOSTNAME.$DOMAINNAME
---------------------
These are the relevent excerpts, of course.
Anyway, I still cannot ping these two accounts.
