I am still having the same problem as last weekend. pinging my Fedora
box by IP address works, but pinging by name does not:

[root@bilbo ~]# ifconfig eth0

[root@bilbo ~]# ping -c4 bilbo
ping: unknown host bilbo

My /etc/hosts shows:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.0.3 bilbo.stow-jones.local bilbo
192.168.0.2 gandalf.stow-jones.local gandalf
192.168.0.5 frodo.stow-jones.local frodo

The last three entries are for the PC's on the network.

/etc/resolv.conf shows:
nameserver 192.168.0.1
nameserver 212.23.3.100
nameserver 212.23.6.100
search stow-jones.local
# generated by NetworkManager, do not edit!

The first line refers to my router, the other two nameservers are my
ISP's.

When I check the status of the named service, I get the following:
[root@bilbo ~]# service named status
rndc: couldn't get address for 'localhost': not found
[root@bilbo ~]#

Is there anything else that I can check to get this back up?
