Re: [Dnsmasq-discuss] one laptop, one IP, two NICs?
A C ag...@hotmail.com wrote: I've got a laptop that uses a wireless or wired connection (never both simultaneously). Is there a way to configure dnsmasq to serve the same IP and hostname to the laptop regardless of which interface is used? Currently other DHCP devices on my network use /etc/ethers to govern which IP they get to ensure a static IP assignment (for things like cameras and printers). Try assigning IP address to hostname, instead to MAC : dhcp-host=hostname,192.168.x.y Regards, David

Rune Kock wrote : After running fine for over a week, my router with dnsmasq 2.45 became very unwilling to answer DNS queries (only a few succeeded). Dumping the statistics showed that a significant number of upstream queries had failed. Restarting the router solved the problem. You might also consider restarting only dnsmaaq instead of entire router. (to see if the restart of dnsmasq helps or something else has to be restarted ...) Regards, David

Re: [Dnsmasq-discuss] The simplest setup to preserve IPs
This is what I do : - nothing in in /etc/hosts (except the usual localhost stuff) - lines in /etc/dnsmasq.conf: dhcp-host=hostname,address Example: dhcp-host=johny,192.168.2.40 dhcp-host=blaster,192.168.2.41 etc...

Unfortunately it doesn't work like that for all my hosts - it does for those that are windows based, and not for the others. For the others it assigns an IP from the dhcp-range and complains about not being able to assign the hostname, because it's present in /etc/hosts and has different IP assigned. Am I missing something? -- Michal Sawicz mic...@sawicz.net
[Dnsmasq-discuss] DHCPv6 support ?
Hi! Does dnsmasq support DHCPv6 ? That is, can it tell IPv6 hosts what gateway and dns server to use ? (I believe that is needed for IPv6 netwrok to function, without manually setting this on each host; I am new to IPv6) Regards, David

Heath Woodson heathwood...@gmail.com wrote: Setting this up for the first time and I have a simple question but it isnt clearly answered anywhere. I want to assign ips with DHCP in a static manner can I just use the /etc/host file on the machine running dnsmasq to do this and uncomment this line # Enable the address given for judge in /etc/hosts # to be given to a machine presenting the name judge when # it asks for a DHCP lease. #dhcp-host=judge I do that by having lines like this in dnsmasq.conf : dhcp-host=judge,192.168.100.41 I tried to do this by putting the entries in /etc/hosts, but it did not work for some reason. Simon, can you help ? Is there an option needed to enable this ? That is: no dhcp-host=xxx line in dnsmasq.conf, but a line in /etc/hosts: 192.168.100.41 judge Regards, David PS: Juggling with MAC addresses is silly, when using hostnames is so much simpler, easier and robust (it still works if one client replaces his NIC for whatever reason).

Thanks, Kunal May I inquire as to the rationale that allows modifications to dnsmasq but not upgrade to the latest version? Simple : Do not do any changes to a working system, except the really necessary ones. This is so in any serious system. Regards, David

I'm having problems working out how to set up a DHCP service with dnsmasq to provide workstations with permanent host names. Thats IMHO a typical setup, i also just use a dsl modem and a full-blown linux box as router, because the config capabilities of those router-in-a-box won't cut my needs (multihomed router, fancy traffic shaping, some servers, etc.). Funny, my router-in-a-box does all that ;-) Second, to assign some hosts a permanent IP-address, even if recieved by dhcp, you need some dchp-host lines dhcp-host=mac-address,name,ip,leasetime ex: dhcp-host=01:23:45:67:89:AB,gondor,192.168.0.3,infinite I use and recommend a much simpler way : dhcp-host=hostname,ip eg: dhcp-host=nitro,192.168.200.21 # actual config I use Adam, I use dnsmasq exactly for the same purpose as you want. And works nice. I recoomed you use a Windows client for testing, as it work for sure. Then when you fix the server, you can try linux clients. It would be good to know you dnsmasq.conf file and other relevant configuration you did. Regards, David
