Ubuntu Networking :: Dhcp3-server Is Not Committing Correct Dns-address To Win XP Client?
Oct 15, 2010
I'm troubling setting up my dhcp3-server.Although I've configured "option domain-name-servers 192.168.1.1" in my dhcpd.conf my windows-xp-clients dns-server address is set to 192.186.1.1.This is strange! All other things seem to work correctly.This is my dhcpd.conf:
I would like to set a double range of IP address with my DHCP3-server. Now, I have eth0 (which is my only network card) with this IP address : 172.16.93.1 and I have created a second interface eth0:1 with this address: 192.168.3.1. The goal is to give an IP address 172.16.93.X to phones (with option 66) and the IP address 192.168.3.X to the computers.
This is my DHCPD.conf : ddns-update-style none; option domain-name "mycompany.com"; option domain-name-servers 172.16.93.1; default-lease-time 3600; max-lease-time 2347200; authoritative; log-facility local7; option ip-forwarding off; default-lease-time 20; max-lease-time 20; .....
Right now my DHCP server work fine, (I means, no error at the startup ) but the server give always the same kind of IP address, whatever if it's a phone or a computer. I notice something "wired", if I put the : subnet 192.168.3.0 netmask 255.255.255.0 { range 192.168.3.100 192.168.3.199; option routers 192.168.3.254; } (Which is first in the dhcpd.conf) after the "subnet 172.16.93.0 netmask 255.255.255.0", the server will give IP address 172.16.93.X at all the clients. Is it possible to give more than one IP range with one network card at the same time? And how set the option 66 to only give IP address (172.16.93.X) to the phones?
Hey guys. I have a client computer PXE booting from my host computer and it is supposed to give the client the ip address 172.16.0.100 however instead it gives it the ip address 172.16.0.208.
I have this set up working with two other computers and there is no noticeable difference other than mac addresses for the network card.
Here is an extract from my '/etc/dhcp3/dhcpd.conf' file...
I have quadruple checked the mac address of the client and it is definitely "00:07:E9:32:16:81" so why is it not giving it the IP address that I have specified?
I have followed the ubuntu guide for setting up a dhcp3-server server for my internal network, I have installed dhcp3-server, configured it refuse to start, here are some background:This is my /etc/default/dhcp3-server:
# Defaults for dhcp initscript # sourced by /etc/init.d/dhcp # installed at /etc/default/dhcp3-server by the maintainer scripts
I have an old Linksys WUSB54G USB wireless card lying around, and occasionally I like to use it as an access point for my laptop. For assigning IP addresses I use dhcp3-server. The only problem is that the server attempts to start itself up on boot, which I do not want- I want to start it up manually if I need it. how to disable this service on boot?
I use F12 and I need help with correct syntax to specify range of IP address in hosts.allow or hosts.deny or in /etc/exports file eg. 192.168.1.100 to 192.168.1.255.
I 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?
I have installed a working DNS server on my home network. I have an unique server, devoted to dns, gateway, storage which runs opensuse 11.0 (I known that it is rather old). Two new clients require DHCP. I have installed, using yast, a very simple DHCP server, according to the following config:
(I have tried to add "ddns-update-style none", and to remove the ntp-servers option, since my server is not a time server, without success). Unfortunately, even if the client (a mac running OSX 10.4) receives a right IP and gateway address, it displays neither dns server address nor default domain name. The same mac, on my office network (not managed by me), receives everything.
I am running Debian Squeeze with the following basic services running:DNS DHCP Samba Squid
The server is setup with three NICs: eth0 (WAN1), eth1 (WAN2), and eth2 (LAN).The server addresses clients with an IP range of 10.0.30.1 - 10.0.30.254. Some clients will be set with reservations so they fall into the 10.0.40.1 - 254 range.
What I want to do is have any outgoing external traffic coming from the first range (10.0.30.0) to use WAN link 1, and any outgoing external traffic coming from the second range (10.0.40.0) to use WAN link 2.
I have sort of got something working. I have created a bare minimum transparent squid3 setup on port 3128, and set the iptables as follows:
I can get internet access, however obviously it only goes through one WAN link. It also seems slower than it should be. I experimented with tcp_outgoing_address, but seemed to not be my friend.
I'm using ubuntu 10.04, Im going to setup LTSP sever, But I cant start dhcp3 server this errors are come, how can I fix this this error comes when I tried to start dhcp3 server
I have dhcp3-server (isc-dhcp-server) installed on my Debian and now I got a question about how it's giving the IP addresses to new devices.
For example: I connected my laptop and dhcp server gave me 192.168.1.5 address. Will it always give me the same ip address when I connect my laptop or it will eventually change after some time (week-month)? If it's not changing it, then I am wrong about this.
BUT...If I am somehow correct and if it will change in a week and give me another random (like 192.168.1.8) IP even I won't change my laptop network adapter, is it possible to configure dhcp server to always give same IP address depending on what MAC it is?
To make it clear, I want that when I connect new device (new laptop/pc) dhcp server would give it random IP but same time it would note the MAC address and never change the IP on that MAC.
I know about MAC filters, but setting filters is when you know MAC address since beginning and want to assign IP for it, but in my situation I don't know the MAC address.
I need to create a network boot from 1 laptop to another, with a crossover ethernet cable between them, no routers no nothing, my computer is supposed to be the server. I followed half dozen tutorials over the internet but I think my major problem is with the dhcp serverfollowed this tutorial[URL]but when the client boots it makes several dhcp requests but doesn't respondwireshark capture looks something like this until the client times out
I'm writing because my ubuntu server has started with troubles . It's running Linux 2.6.32-29-generic-pae kernel for ubuntu server 10.04 and after the last update it stopped from giving addresses on clients connected. Dhcp3 server it's running and the conf files are fine, but i can only use static addresses assignation now... Also MYSQL has stopped working (installed for Bacula purpose) but now the dhcp problem is the biggest issue. I work in an office where dhcp is fundamental, too much clients (about 15) that are personal laptops also (so static assignation for clients is not a good choose). Please any one could help me? It's two days I'm trying to figure it out without success. also tried removing and reinstalling dhcp3-serer...no way. Here are my conf files code...
Have DHCP3 running on an ubuntu server. Using config of the below but the 10.1.1.2 address is being given to a windows pc (which does not have that MAC address). Tried getting windows to release ip address, then clearing the lease file and restarting dhcp3 service, then renewing dhcp request from windows, but address 10.1.1.2 is still given.
I've been attempting to figure this out for about 4 days straight, so far it has not been fruitful. I've installed Ubuntu 10.04 server onto my former gaming system, Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz, 2 cores with 2 GB ram. Overkill I'm sure, especially for a simple personal voip, htpc, storage server.
The problem is only noticeable when I have the vent server running, on the 10.04 server, and I attempt to connect to it through the LAN via the client on my windows computerEverything works fine and connects, LAN and from the outside, as long as the server is set to DHCP. However when attempting to switch to a static IP address, the vent client will not detect the vent server at all.Aside from an annoyance at having to stick with DHCP, I am still curious as to why the static settings will not function. Something so simple has turned into something quite difficult.
I can still connect to the Webmin interface and Putty into server with either DHCP or static IP enabled.I've performed the following troubleshooting steps so far:1) Followed the directions at https://help.ubuntu.com/8.04/serverg...iguration.html2) Edited the /etc/network/interfaces file through the CLI with nano and through notepad on the windows computer3) Through Webmin I've assigned the static IP, although for some reason it does not include a gateway field.4) I've rebooted the server5) I've issued the CLI
Code: sudo /etc/init.d/networking restart Here is the file /etc/network/interfaces:

I been trying to set up a DHCP3-server on my brand new learning Ubuntu 11.04 server. I can connect when i put the IP infomation in manually, so I know everything else is working, just got to fix the DHCP problem before I put the machine into production on my home LAN. Can someone tell me if these config files located at /etc/dhcp3/dhcpd.conf and another at /etc/default/dhcp3-server are correct? eth1 is the NIC that will be the LAN side of the network, I double checked that...
Code: /# A slightly different configuration for an internal subnet. subnet 192.168.10.0 netmask 255.255.255.0 { range 192.168.10.10 192.168.10.200; option domain-name-servers 8.8.8.8, 8.8.4.4; option domain-name "linuxrouter.local";
I have installed Kubuntu Lucid x86 10.4 LTS for the first time. Has anyone got a link that explains how KPackageKit gets the IP address of the repositories? I can install packages using sudo apt-get install xxx OK . KpackageKit tells me I have updates from the repositories. I can select them all and apply , but I get an error that it can't find the repository under a 192.168.100.129:8080 address . Which is not a surprise . I am using mirror.optus.net as a repository and can ping it fine on the command line. So is there somewhere else that KPackageKit maps IP addreses ? I have tried another mirror mirror.aarnet.edu.au and got similar results. My local sub-net is not 192.168.100 and have tried setting fixed IP on the local sub-net and different DHCP addresses and still the same error.
v10.4 {I have completely re-edited this thread because I have started over fresh. I am no longer using bind9, but now using the installation-defaults nameserver and dhcp and trying to get a handle on how things ought to be setup properly. My previous attempts was a disaster.}
Coming fresh out of a newly installed 10.4, I obviously was able to get network connectivity but then I ran into trouble the minute that I tried to change eth0/eth1 connections via network-manager's applet. What I found was, that when I attempted to define static connections, all bets were off. It seems that once one attempts to change eth0/eth1 which are wired devices, I was no longer able to recover my network connectivity!
I was however able to setup a wireless connection, so in this way I was able to get back network (and Internet) connectivity, and write this thread on this forum. I notice also, that there is no longer 'Networks' in the System->Administration menus! Geez, what the hell is going on? how to properly configure my static wired connection? Networks in 10.4 have really changed alot!
I configured openLdap in RHEL5 on virtual achines,everything is working fine, I created a user called ldapuser,in LDAP server and i created a home directory for ldapuser in my LDAP client, now i can able to login to the both Server and client with ldapuser account....
Now here what am expecting is i want to export my server's home directory to the client, i dont want to create home directories manually in the client machine, i googled about that, and it can be done through autofs.....
what need to be done on the client and server side.
I've been using opensuse 11.2 and windows xp at parallel. After I decide to reinstall windows, I got the error saying "invalid partition table" after the first restart of windows xp installation.
I tried to use windows system recovery console and committing fixmbr and fixboot commands, but didn't work.
After all, i boot with opensuse livecd to run the grub and got my opensuse back.
How can I installed windows on a opensuse installed system? My plan was first to install windows xp, then opensuse again.
I have 2 ethernet cards but when I look at the Network configuration in "Hardware Tab" I have another acx wireless network. How to delete that because In my system Idon't have wireless card..probably installed before but want delete it now.
[code]...
then windows can ping server and resolve ip address and browsing Internet but can't ping [URL]... result is Request time out. ICMP already enabled in iptables.
i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through
I have a wireless router situated in another room. I am able to access this router (and consequently the internet) through a Windows laptop that has a wireless card in it. However, my other laptop that has Ubuntu 10.10 installed on it, doesn't seem to have a wireless card in it, and I have confirmed this by running the commands
Code: lspci and Code: iwlist scan
I briefly was able to share a folder in my Windows machine, and access it through my Ubuntu machine, after connecting both laptops with a cross-over cable. However, I can't even ping the Windows machine from my Ubuntu machine anymore, after trying to configure the IP addresses. I think I screwed it up.
Also, although this is not an Ubuntu issue, I have a weird Windows problem, where I can't access the Internet when both wireless and wired ethernet controllers are active at the same time. It would be a bonus if you could solve this problem too for me. I was surfing online for a solution to this problem for quite some time, but I was unable to comprehensively understand and implement what I browsed through. Also, some of the guides, like for example, that on configuring Samba, seem to be outdated, as the terminal tells me something like the package (that was required to be installed by the guides through sudo apt-get install) has been superceded. Hence I post here for clear, concise and easy-to-understand help from you gurus. It would be great if I could achieve the end result of being able to access the internet on my Ubuntu machine (through the Windows one).
I'm trying to run a server, and want to get my IP address but when I run ifconfig, it shows my inet address as 10.0.1.9/10.0.1.4 which, if I recall correctly, is an internal address... my friends can't connect to the server on those ip addresses. My box is wired to the internet, no router, so there's no firewall or router that could be stopping it. Am I doing something wrong with a command, (reading wrong number, etc), or is it a system problem?
