General :: Dhcpd Can't Create Dhcpd.pid Ubuntu 11.04 (natty)
Jun 20, 2011
I've found a lot of pages of how to fix the issue on older releases of dhcpd and ubuntu.
#>dhcpd
#> ...
#> Can't create PID file /var/run/dhcpd.pid: Permission denied.
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

i want to do a setting to dynamically monitor my Work Station on my Wifi network.
I've got my name server BIND and my dhcpd server all of that under linux working perfectly. But i didn't find any option to execute a script when dhcp give an IP to a machine. I would like to know if there is a way to do that. If there is no options for that i'll use the log files.

My dhcpd service get failed every time when I try to start it
1) Actually I have a lan connection which has a static ip network 192.168.10.0/24 and the pc to which is using the dhcpd has a ip address 192.168.10.1/24
2) And I have a internet connection wirelessly which has a network 192.168.2.0/24
Now I want to problem ip address in the network of 192.168.10.0/24
Here below is the configuration file of dhcp server:
# dhcpd.conf

# Sample configuration file for ISC dhcpd
#
# option definitions common to all supported networks...
option domain-name "example.org";
option domain-name-servers ns1.example.org, ns2.example.org;
# Use this to enble / disable dynamic dns updates globally.
#ddns-update-style none; .....

I am trying to install dhcpd on my Fedora 13 VM. I'm using VirtualBox and I installed using the i686 image. I did yum update and everything was fine. When I do yum install dhcpd , I get the following error.

I have setup a dhcpd server on my lan with the following option to reflect the static route to my private LAN.
dhcpd.conf
Code:
option static-routes 10.0.0.0 192.16.5.0
I've tested it on OpenSUSE, ArchLinux and even Windows dhcp clients and they've managed to pull the static route configuration. However, to my suprise on my ubuntu machines this doesn't seem to load. Is there anything that needs to be done on the client's side to get this to work?

On my local network, I use my Linux machine running dhcpd and IP masquerade as a gateway to the internet. As it is, the setup works just fine, and I've enabled dhcpd in all runlevels in the services dialog, but for some reason, it still does not automatically start when I boot the machine. If I select it and click "Start", it operates normally, and if I run "services dhcpd start" from a command line, that works too. My only guess is that it's some problem with my config file... it's the same setup I used with previous versions of Fedora without issues, but maybe things have changed?
The contents of /etc/dhcp/dhcpd.conf:
Code:
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
option routers 192.168.1.8;
option subnet-mask 255.255.255.0;
option domain-name-servers 64.59.176.13, 64.59.176.15, 64.59.177.226;
option ip-forwarding off;
range dynamic-bootp 192.168.1.100 192.168.1.200;
default-lease-time 21600;
max-lease-time 43200; }

I also tried yum clean to clear cache but that didn't help either. I installed Fedora 12 in a different VM and tried but with no luck. Also tried installing using i386 DVD but same error. I should also mention that what I'm trying to do is that I'm trying to set up a relay agent on my Fedora gateway.

it appears i haven't quite grasped the meaning of dhcpd.conf despite the numerous tutorials i went through in the internet and the detailed read of dhcpd.conf that i did. what i basically want to put you in perspective, is to have all the pc's in my home network (desktops and laptops) regardless of any other settings, to send their computer name (hstname basically) to the dhcpd (during the handshake)... then the dhcpd will use that name as the hostname and append the known domain name, thus creating an entry (an A record and a PTR record) in BIND....
so say a laptop comes into wifi range of the domain "myhome.org."... i take it that during handshake, the laptop will send its hostname (i don't know what that will be for winXP and win7 dhcp clients, but i presume it will send the output of command 'hostname' for linux clients - or at least thats what i would like it to send....).say "nass-notebook" Then the server will append "myhome.org." and it will update the DNS with an entry looking like[URL].. corresponding to some ip address.

I am trying to provide dynamic IP addresses for devices that are on a different VLAN (101). The server is currently providing 172.17.x.x/16 range for its own VLAN (417). My server is RHEL4 and DHCPD is version 3.0.1. The core switch (Cisco 3750) is configured with ip-helper on VLAN 101 interfacce. Here is my dhcpd.conf file:
authoritative;
ddns-update-style ad-hoc;
omapi-port 7911;
shared-network eth1
[code].....
However my laptop on the VLAN 101 keeps getting IP of 172.17.x.x/16 range..

For some weird reason dhcpd fails to startup, but when I installed gadmin's dhcpd GUI configuration tool and click activate to start the DHCP server. It works, but for some reason I can't get it to start like a regular service. (Service dhcpd start) Fails without a error code or message.

I just installed F12 from scratch and I'm facing a curious situation with dhpd. The service is enabled, but It fails to start on boot. I see the following error on /var/log/messages:
Jan 18 17:15:28 neo dhcpd: No subnet declaration for eth1 (no IPv4 addresses).
Jan 18 17:15:28 neo dhcpd: ** Ignoring requests on eth1. If this is not what
Jan 18 17:15:28 neo dhcpd: you want, please write a subnet declaration

Jan 18 17:15:28 neo dhcpd: to which interface eth1 is attached. **
However service dhcpd start, works just fine when I login, after the system boots:

So it can't be a problem with my dhcpd.conf file.

How can I start dhcpd after Network manager has set up a new connected device. The reason being that dhcpd will not start when there is nothing connected to the network interface. Therefore I would like dhcpd to start after a new device is connected. Now I have found references if ifup-post but this does not relate to NM, is this correct?

I am a Linux newbie using Oracle Enterprise Linux version 4 update 7 (its almost similar to Redhat Linux). While going through tutorials, I tried to configure the DCHP service and set it to start after every boot via the command
chkconfig dhcpd on
When I boot my Linux,the OS hangs when it tries to start the dhcpd service.Thus,I cannot log into my Linux and shutdown the service. How can I go around this and shutdown the DHCP service to enable my Linux to fully load after a boot?

I'm having some trouble with getting my DHCP service up and running on my server. Below is my /etc/dhcpd.conf file, which I believe is the right file necessary to get this service up and running correctly. When I do service dhcpd restart it just show in red letter [Failed] next to it.

I'm trying to get dhcpd to use a specific IP address as the source address for responses it uses an IP address for. I coded "local-address 172.30.0.4" in the config file. For some responses it uses this address. For some other responses it does not. In those cases it uses the IP address that is the first on the interface. Is there another configuration I should be using, instead?

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:

ddns-update-style ad-hoc;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.1 192.168.0.100;

I've a question about how work dhcpd. I'm on CentOS 5.6. I has a dhcpd server on it. His configuration:
authoritative;
ddns-update-style none;
deny declines;
deny bootp;
option domain-name "mydomain.domain";
option domain-name-servers IP;
option routers IP;
option time-offset -18000;
#option ntp-servers IP;
subnet IP netmask MASK {
range IP START IP END ;
default-lease-time 86400;
max-lease-time 172800; }
And now in the /var/lib/dhcpd/dhcpd.lease file, there few entrie for the same IP. Sometime I've ten same entries for the same IP. Can I have only one entrie by IP? Is there any problems in my configuration of my dhcpd.conf file?

i have to define new dhcpd options to provide data for a pxe winpe boot. So these options will be under a bootstrap session. This doesn't work.
option ff code 145 = text;
option ff "test";
option sitepxe code 138 = text;
option sitepxe "test";
option clienthostname code 139 = text;
option clientMAC code 140 = text;
option bcdmenu code 252 = text;
In a wireshark capture i can't see the new options in the DHCPACK packet. ISC-DHCP is always restarted when the conf file is updated.
