Server :: Setup A Net With A Dhcp + Dns Server Using Dnsmasq
May 18, 2010I'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

Ubuntu Servers :: Dnsmasq DHCP Nor DNS Working?
Jun 11, 2010I 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.

Jan 9, 2011I 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.
Software :: Is It Possible To Setup DNSMASQ
Apr 19, 2010Is 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.

Feb 17, 2010I 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.

Fedora Networking :: DHCP Server Intitial Setup - FC 13
Jun 5, 2010I decided to forgo my router's DHCP capabilites and try to make a random computer at my home take on the job.
First of all here's my network topology:
I have a cable modem hooked up to eth0 on my linux box, and this is where my internet comes from and works fine.
I also have another ethernet, eth1, which is connected to a wireless router in bridge mode. My end goal is to have my linux box sit between my internal network and the outside world. Thus it will need to act as a DHCP server, a NAT and as a firewall. Right now I'm just focused on the DHCP part.
Here is a copy of my dhcpd.conf file:
My /etc/sysconfig/dhcpd file has:
However the issue is that it is still listening on eth0. and not issuing any leases on my internal network.
What I think is happening is that it's not recognizing the 10.0.1.x subnet because my router is issuing leases on the 169.254.193.x, even though I put it on bridge mode. But I could be totally off mark.
Also running tcpdump on eth1, I can see requests coming in for dhcp, but my server isn't responding to them.

My problem is centered around using a AT91SAM9G45 development board (DB)on Fedora 10. I have directions on how to setup on my host machine a DHCP server to connect to the development board.

View 1 Replies View RelatedUbuntu Networking :: DHCP Server No Longer Responses To DHCP Requests - Can't Ping Gateway
Oct 22, 2010Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static
[code]....
why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

Networking :: Configure A (openSUSE) Client To Dhcp To EBox DHCP Server - Lease An IP Address
Mar 25, 2010I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4
openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108
openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67
openSUSE11232CL1 dhclient: send_packet: Network is unreachable
openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?
