General :: DCHP Server Or Dnsmasq?
Jul 15, 2010
GUys im trying to setup a linux router w/in our network here in school, and i was using a fc13 as my linux router, i already setup iptables for linux masquerading.. i have a 20 winxp client connected to the said router with an ip of 192.168.0.1, on each client i manually configured all of the clients ip address.. i was wondering if i could use a dhcp server to ease the manual configuration.., i already installed a dhcp server. Note im a newbie, thus dhcp server will also provide dns resolution to winxp clients??,, on some thread that i read if the client is linux.. you will just need to add nameserver to the /etc/resolv.conf for each linux clients.. the clients that im using here is winxp, i was wondering if i could setup the server to distribute dns & also a dynamic ip to all the clients..w/c 1 is better?? DCHP server or dnsmasq??

I am using DNSMASQ on a Debian 5.0.6. server. I configured DNSMASQ as DHCP server, and want it to answer local DNS requests. However, I am unable to use hostnames, and am forced to use IP addresses when pinging, opening a ssh shell on a remote server, opening a remote desktop to a windows system etcedtera.
Because I use DHCP, I can not hard code the ip addresses in the hosts file. How do I configure DNSMASQ so that i can use hostnames for computers who get their IP addresses from DHCP.

I've set up a very simple net with a dhcp + dns server using dnsmasq. It works but the server itself cant resolv clients names. Clients do resolv without any problem my /etc/dnsmasq.conf

I got a CentOS server setup as a dhcp server using dnsmasq. I followed this guide more or less: [URL] So, the problem seems to be concerning the DNS server on the clients. In windows I get the "limited connectivity" icon for the network, and when I select troubleshoot it says the DNS server does not respond. Issuing 'ipconfig /all' clearly shows the IP of the CentOS machine as the DNS server, which should be correct, yes?
ETH0 is working as WAN connection and that works great.. no problem with the WAN connection at all on the CentOS machine. ETH1 has the IP 192.168.0.1 and mask 255.255.255.0 When starting eth1, it sometimes says that it can't start eth1 because the IP 192.168.0.1 is already in use.. but that is most certainly not the case. Maybe there's some kind of issue here that messes with the DNS? What's mind boggling is that it works great on a linux machine (dhcp client) and on a windows xp machine. but it does not work on the windows 7 laptop and a vista laptop and a pda device.

trying to configure a Centos 5.5 server (simple file server with DHCP and DNS relay). I configured and tested the config (by 'service dnsmasq configtest') of dnsmasq and I got the message 'dnsdomain:host unknown (translation of the real message : hte inconnu) and I didn't find where I could define this host ! The hostname of the server is well defined and I can see it from all Windows PC's on the LAN. dnsmasq starts (with hte same message as in configtest) but when querying DNS from PC's te.g. trying to surf the Internet), I don't get replies (3 DNS servers are also well defined and operational).

It says that this is a bad option
dchp-range=ignore,192.168.1.99,192.168.1.99
I am very new to linux but it says that's a bad option to why my dnsmasq service isn't running.

I've trying to get dnsmasq working as a combined dns and dhcp server. It's infuriating so far... In short, the DNS works fine for anything added to /etc/hosts, and the dhcp works fine, but the dhcp is not updating the dns with hostname information from clients.
The outcome of this is that i can only ping a node by hostname if i know it's address, which means setting a static dhcp allocation and putting the hostname into /etc/hosts manually, which is very annoying and kind of defeats the poit of dhcp. There must be a way to get dnsmasq to update the hosts file, surely The clients aren't using fqdn's if that matters, and i think i've tried every combinination of "expand-hosts" and "domain=" following is the dnsmasq config file contents:
domain-needed
bogus-priv
except-interface=tun0

I know a fair amount about setting up a simple network but I'm curious about setting up a more complex topology...For example...A "box" has two NIC's acting as a bridge, normally this would involve two distinct networks (ie. 192.213... and 192.214...) is it possible that this physical set up can create a single network (192.213... 192.213...) resolving IP's from either a DCHP on the "box" or a DCHP server somewhere else on "one side of the box"likewise with differing physical network types, a "box" with a NIC and a TCP/IP over usb setup connected to another device with TCP/IP over usb (OTG/Gadget) so that all the IP's are on one logical network.

Is it possible to setup DNSMASQ so that it respects the TTL it is given by the upstream DNS server, but it sends out a fixed TTL to its clients?My DNSMASQ server is running on the same local network as all its clients. I want all my clients to be served with a 5 minute TTL, regardless of what the actual domain uses. So for instance if google.com has a ttl of 60 minutes, then I want DNSMASQ to cache it for 60 minutes, but I want my clients to receive a TTL of 5 minutes so that they query my DNSMASQ server again every 5 minutes. I basically want to avoid having each client's OS doing any caching.

I have configured a Fedora 10 server on a mixed Win / ix network but am unable to get DNS to resolve on my Fedora boxes.My DHCP is provided from a D-Link 108G Router - but this will not provide DNS.Therefore I have tried to configure dnsmask to provide just DNS and not DHCP. I can ping around my 192.168.1.x network by IP but not name

I have been rtying for a couple of days now to set up a local dns/dhcp server with dnsmasq on a ubunut server 10.04 I followed the basic instructions from several websites, starting with the ubuntu community one, didnt work, then tried some other, and nothing.
In the server the dns works, i test with dig example.com and i can see the time difference, so dns is working. so the problem is not making the dns work but to make the server listen for dns and dhcp resquests and respond to them.
I have desactivated the dhcp from the router so thats not the problem. making a windows box ping the server works, so the network is configured correctly.
dnsmaq is listed as "LISTEN" on netstat, i read in some blog that it should be using ports 67 and 68 but those are no listed, neither i configured them in any moments, none of the instructions i followed mentioned sth about that. i even tried configuring the window box with the ips and dns accordingly and that wouldnt work either.
so in conclusin i have dnsmasq that does have dns set up but wont answer to any requests of either DNS nor DHCP.

I am trying to get more control of my small office network. It consists of several windows workstations, a debian box, and a ZyXEL P-660HW-D1 router, Right now, the only way to reach the debian box from other computers is to type in its ip address.
The goal is to be able to reach the box by just typing ://debianBox into my browser, though ideally I want to set it up to be something like ://debianBox.officenet, and to also reach other people's computers by typing ://mattBox.officenet and ://fredBox.officenet
The Zyxel router has a LAN page with a DHCP Setup tab with fields setup like so In the past I was able to mange this using an Orange router, but now I have to use the ZyXel.
So I installed dnsmasq on the debianBox, but I do not know how to configure it to get the results. I want and still get internet fromthe Zyxel router.
In the etc/hosts file of the debian box I added 192.168.69.15 debianBox, and for testing on my windows machine I set the primary dns entry of the Ip4 connection to 192.168.69.15 as well, but typing ://debianBox in my browser still gives me not found.

This is the scenario: gentoo box (distro shouldn't be relevant here) and win7 box. Gentoo box is dhcp and dns server, via dnsmasq. From win7, I can ping gentoo by both ip and name. No problem there. From Gentoo, I can ping win7 by ip, but not by name. The dnsmasq log seems to receive the name ok, it's "Tere-PC". I have been looking around for many hours now and I know there must be something simple I am not taking into account.
Code:
dnsmasq-dhcp: 55480937 available DHCP range: 192.168.0.50 -- 192.168.0.150
dnsmasq-dhcp: 55480937 client provides name: Tere-PC
dnsmasq-dhcp: 55480937 vendor class: MSFT 5.0 .....
Code:
# ping Tere-PC
ping: unknown host Tere-PC
Is there any way that dnsmasq, which is supposedly a dns server, will link this name to the given ip?

I have 2 questions:
1. How can I set the TTL to 2 days for all stuff cached by dnsmasq?
2. When I go to [URL] from my browser and then execute [URL] the query time returned is > 0 ms. When i execute it again it is 0 as it should be. So is dnsmasq not caching the domains looked up by my browser or what? in /etc/resolv.conf I have only 127.0.0.1 and for the upstream servers I have a different file that is only used by dnsmasq.

Since latest large update to CentOS 5.3, which also upgraded to 5.4, I have problem with dnsmasq. CentOS is real server on real hardware (not virtual). I use dnsmasq as dhcp server as usual. On hardware startup or reboot, these lines are included in /var/log/messages

My upstream DNS server is a bit slow, so I've installed the dnsmasq cacher locally. I have the service starting on runlevels 2, 3, and 5. But I can tell by Firefox's behavior that dnsmasq does not work upon boot. Firefox lets its own DNS cache expire after 60 seconds. When I do my second Google search five minutes after my first, the second DNS lookup for www.google.com is just as slow as the first.If I manually restart the dnsmasq service, I get the fast name resolutions I expect.

On a Lucid server, dnsmasq is happily running DHCP together with a local DNS; although, in setting up NFS, I seem to have a small problem... I have /etc/exports referencing the hostname of the clients but these IPs change when the DHCP lease is renewed. Unless I restart NFS or run exportfs, I cannot mount the exports on my clients. I know that it would be good to make the all the addresses static; however, I was wondering whether there is another way to configure NFS such as possibly adding in a script to continually monitor /var/lib/misc/dnsmasq.leases and re-export accordingly?

I have it working fine when tftp and dhcp are installed on the same server but when trying to forward to a remote tftp it does not work. Dnsmasq insist on giving its local ip.I have added to config:dhcp-boot=pxelinux.0,pxetest2,192.168.0.130and I tried with and without the original hcp-boot=/var/lib/tftpboot/pxelinux.0Not much on this topic on the google nor on the dnsmasq homepage.
