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 installed dhcpd using:

Now when I try to run it, I get this weird error:

It's got something to do with AppArmor.

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've never had this much trouble, but maybe it's because I have not setup a dhcp3-server in some time.
My server has three NIC cards. The Internet connection is on eth2, and I'm trying to get connect other computers to the server through eth0.
It's suppose to be relatively easy, unless I'm assigning specifics, right?

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?

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!
Had problems with internet and deleted this by mistake now how do I get it back? note that I have no internet access so I cannot use Synaptic.
View 1 Replies View RelatedI 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?
I have a question regd. reservations for the system GID's/UID's in Redhat. I understand that numbers <500 are reserved for systems and >500 for users. In the former, is there a range that is reserved for private use (like the 10. range in the case of IP addresses)? I need to create a system group and user and specify a GID and UID and I would like to make sure that the numbers do not conflict with some other package.
View 1 Replies View RelatedWhile configuring dhcpd.conf on centos 4 I couldn't find option to reserve that ip addresses. I have subnet of 10.0.0.0 network of which i want reserve 1 - 50 addresses for my servers. I'll assign static ips to my servers & printers.

Here's the problem -- DHCP wont start and throws the error "Can't create PID file /var/run/dhcpd.pid: Permission denied." Somewhere I found a post that indicated that the following corrected the issue (I dont really know why):
ln -s /var/run/dhcp3-server/dhcpd.pid /var/run/dhcpd.pid
dhcpd3 -cf /etc/dhcp3/dhcpd.conf eth1
When I do the above DHCP will start (in theory, at least no erros are thrown). But if I ask DHCP to restart, it will stop, but not restart. And the error is "No subnet declaration for eth1 (192.168.3.2)"

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.

I been trying to set up a DHCP3-server on my brand new learning Ubuntu 11.04 server.

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...
ddns-update-style-none;
option domain-name "example.org";
default-lease-time 600;
max-lease-time 7200;

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 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 just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.

On one machine I was able to turn off ipv6 in grub and reboot, and it works now. However on the other 2 machines, still have the same problems. All 3 are running 9.10 64 bit. Is there a way I can back out the updates so the network works again? Anyone else see this behavior after updates today?
