I have set up a household network being masqueraded onto the internet
through a redhat 6.1 box. The network works fine except that if I try to
access the machines on the local network by hostname then the host will
always query my ISP name server before querying my local hosts file. Thus
causing a delay of 10 to 15 seconds.
from /etc/hosts (192.168.105.128)
127.0.0.1 dorfl.discworld dorfl localhost
192.168.105.38 luggage.discworld luggage
from /etc/host.conf (192.168.105.128)
order hosts,bind
multi off
I thought that this should prevent nameserver lookups of hosts present
in /etc/hosts
Does someone know what I am missing?
139.134.5.51 is my ISP nameserver
192.168.105.38 is luggage, the masquerading gateway (RH6.1 Linux 2.2.12-20)
192.168.105.128 is my computer (Debian Woody Linux 2.4.0)
This is the network activity from the command
>$telnet luggage
from ethereal
