NAME
dnsmasq - A lightweight DHCP and caching DNS server.
SYNOPSIS
dnsmasq [OPTION]...
DESCRIPTION
dnsmasq is a lightweight DNS, TFTP, PXE, router advertisement and DHCP
server. It is intended to provide coupled DNS and DHCP service to a
LAN.
Dnsmasq accepts DNS queries and either answers them from a small,
local, cache or forwards them to a real, recursive, DNS server. It
loads the contents of /etc/hosts so that local hostnames which do not
appear in the global DNS can be resolved and also answers DNS queries
for DHCP configured hosts. It can also act as the authoritative DNS
server for one or more domains, allowing local names to appear in the
global DNS.
Então, parece-me que você deve (em todos os clientes) adicionar /etc/hosts
192.168.1.1 www.mywonderfulsite.com
Quaisquer outros asliases para 192.168.1.1
devem aparecer na mesma linha, não linhas separadas. Múltiplas linhas em /etc/hosts
com o endereço IP SAME causam confusão, perplexidade, frustração e alguma cabeça latejante na mesa.
