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

The error was:

It's got something to do with AppArmor.

I have a router with ddwrt on it that runs a DHCP server. What I want to do is only allow people who have pre-determined MAC addresses to get an address to get on my network. That being said I have a VM set up as a DHCP Server. Since doing this I will be setting the dhcp settings on my router to be a forwarder to the VM. Is there a way to allow only static leases in the dhcpd.conf file? I do not just any computer on my network to get an address I want to base it on MAC addresses.

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 newbie-ish. Help me Obi-Wan Kenobi.
While 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.

Is there any way to associate a group to subnet in dhcpd.conf? I want hosts in a specific group to be locked to an IP range defined in subnet. Something like this:
Code:
authoritative;
ddns-update-style ad-hoc;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.1 192.168.0.100;
option blah1;

i configured my laptop (running UBUNTU 10.04 LTS) for my broadband (bridge mode). I did that using PPPOE CONF command. Everything goes ok but only prob is i have to run this command and configure my net every time i restart my system. What i need is it should connect to the net whenever i use the PON DSL-PROVIDER and must turn off by using POFF..
View 1 Replies View RelatedMy Internet connection runs slow and jerky, but can be fixed by using the Google public nameservers instead of the default one in this file. Problem is, the changes keep being reverted, even when I chmoded the file to have read-only permissions by everyone.
How can I change the nameserves permanently?

I have tried creating the file and giving it permissions to be accessed, but that isn't solving the issue. I tried to go through some of the older fixes, and one was really close to working but lacked the same folders as I have.
EDIT: one solution that worked was to use ln -s /var/run/dhcp3-server/dhcpd.pid /var/run/dhcpd.pid dhcpd3 -cf /etc/dhcp3/dhcpd.conf at0
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.
Code:
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
[code]....
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?

For assigning IP addresses I use dhcp3-server.

So I'm trying to get two fingered scrolling on my Ubuntu 10.10 netbook.

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 did these steps to change my username: I like to directly edit /etc/passwd and /etc/groups
First open a terminal, become root
Code:
sudo -i
Now:
Code:
usermod -d /home/new -m old
sed -i -e 's_old_new_g' /etc/passwd
sed -i -e 's_old_new_g' /etc/group<-
sed -i -e 's_old_new_g' /etc/shadow
My computer shut down after I did the second step and now my password isn't working! I cannot open my home folder or get back to root!
I have an HP Deskjet D1460. I am using Ubuntu 10.04 and HPLIP 3.10.2 that came with the distro. I am in a plan of moving my windows PC to ubuntu in my bussiness, and this is the first of them. Trying to solve all the problems before converting a second one. All seems to work quite well and almost out of the box... and that is a huge step from the last distro i tryied 2 years ago. So, my difficulty now resides on the printing. I am using a small VFox program that manage some of the aspects of the bussiness, in wine. It works without problems, but... when I print, all the pages get printed like 1cm below than when it was printed under windows. The problem is, that I use the printer to fill some forms that came pre-printed, and now, I am printing over the other text instead of the white spaces. I read a little, and try to adjust the HWMargins and the ImageableArea in the ppd of /etc/cups/ppd/ but it was like if I was doing nothing. Do I miss a step? Do I need to restart a service or something after changing the ppd? The margings when using the printer gui from Ubuntu are all in 0, and for that i need like a minus something.
