I am using dnsmasq with dhcp turned on to make a wireless access point
on a computer. The computer is connected with a cable to a
I have computer 1 connected to the modem/router, computer 2 connected to
the modem/router with a cable. Computer 1 is using dnsmasq without dhcp
and it gets an ip address using dhcp from the modem/router. Computer 2
gets an ip address using dhcp from the modem/router connected by cable.
Computer 2 has dnsmasq running with dhcp and also hostapd and a wireless
card. Computer 2 becomes a wireless access point. Computer 3 is a
laptop that can connect wireless to the modem/router or the computer 2
access point. Everything works fine as far as connecting to the
internet. Computer 1, 2, and 3 all resolve internet addresses.
Computer 3 works whether connected wireless to the modem/router or the
computer 3 wireless access point. At any time, more computers can be
The question I would like to resolve is about the computers all talking

a result of this, using ssh for example by host name does not work. I
can ssh by using the private ip address. I would like to be able to use
things like ssh, NX, ... using host names and have them work. Is there
a way to have dnsmasq do this without having to statically fix hosts to
What I would like to do is set up dnsmasq to resolve local/private hosts
to local/private addresses not public addresses.
