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 have setup a CentOS 5.5 server as a DHCP server. That will be it's only task in a Cisco callmanger VoIP environment The DHCP server that comes with CentOS 5.5 is from ISC V3.0.5 -redhat.
The server (HP DL360) has two physical NIC's of which only NIC1 is used (ETH0)
ifconfig shows:
Code:
The interface has a fixed IP setup.
My dhcp.conf file looks like this:
Code:
When I start (try to) dhcpd via the service interface or via the prompt as
Code: service dhcpd start
I get an [FAILED] message and the following is in /var/log/messages
Code:
But when I start the DHCPD on the comamnd prompt in debug mode it looks as follows:
Code:
and /var/log/messages shows:
Code:
Why does the system ask a declaration for eth0 0.0.0.0?
Just for information in case if it is important to start dhcpd and named: Sep 16 20:26:44 LINUX-SRV named[2417]: nss_ldap: could not search LDAP server - Server is unavailable Sep 16 20:26:44 LINUX-SRV named[2417]: nss_ldap: could not search LDAP server - Server is unavailable
Secondly Both config files in /etc/sysconfig set parameters to start in jail root but
I configured httpd.conf. With ip, port 80 and specified the document path correctly. But service httpd restart shows httpd stop fail, httpd start fail.

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.

However service dhcpd start, works just fine when I login, after the system boots:

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 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'm configuring a new Centos 5.5 server in replacement of an old W2K server.The topology of our network is simple : one file/dhcp/dns relay server and workstations (PC's and some MAC's) plus network printers and scanners.All the workstations have dynamic IP addresses (easier because a lot of 'dynamic' changes : new persons with their own laptop, ...) and the server and printers/scanners have fixed IP addresses.I edited the dhcpd.conf (see here underneath), I have the file dhcpd.leases but it doesn't start !
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?
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.
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 just got the problem while starting the dhcp daemon. Its showing failed. I need to start it for my clients to be autoinstalled. I am having CentOS 5.2 linux. I've installed all optional packages also while installing CentOS. How to start the dhcp daemon? I've tried the /etc/init.d/dhcpd start also. But it didnt work. Showing Failed.
I installed MySQL and I want the service to (always) start. When I google I always find the same answer; Goto System > Administration > Services. But I don have it. Administration for me goes from 'Printing' to 'Software Sources', so there's no 'Services'...
Also should I be able to start it from a shell, but I also can find that. (I have no /etc/rc.d/-directory and my /etc/init.d/-directory han no 'mysql'). I just started using Linux a few days ago (I only used MaxOsX and Windows before).
I have a service/daemon that won't start from boot. I have used the chkconfig --add <script name> command that went ok I also used the chkconfig <script name> on and that seems to be fine and I have made the script executable Chmod 777 <filename>. By all account it looks like the script is running at boot the the services has not started. When I do a ps -ef | grep ndb_mgmd this process is no there. the script can be run from the console and sems to run fine!

I know I have to count how many instances are running: ps x | grep apache2 | wc -l result if it's running: 2, or else: 1 I also know there is a command called test that I could use to perform the verification, but I don't know how to use test with wc
I have installed version of ntop 4.0.3 by guide.But I can't start ntop daemon/service. I didn't find a service file for starting.During the installation there was no problem only want to RRDTool so I installed that. Now there is no necessary package required.
I have found so many ways for root user to execute commands in so many possible path locations - but having difficulties on executing commands as normal user - during start up.This is what i've got for /etc/rc.d/rc.local script:Code:su -l user && (/bin/sh svc_cmd.sh &)But the command doesn't run at all...
I have centos 5.3 installed, while restarting httpd service I get error starting http:/bin/bash line 1 9941 segmentation fault /usr/sbin/httpd. If I stop httpd service and start it will start but if make service httpd restart it give above error.

I am new to Linux and I am trying to set up a mail server using postfix. I have done all the configurations(hopefully correct) and all the test seems to work except 2 things.
1) Postfix is running but when I try to restart the service it always fails. I checked the /var/log folder and there are no error messages. 2) When I try sending e-mails using outlook, outlook fails to connect to my server.
I am wondering if I have done the configurations properly. I am a little confused in regards to hostname and domain name. When I do a hostname on the terminal I see the hostname that I gave my server. When I do the domainname command however, domain is none. Is it necessary to have a domain to configure postfix? I have myhostname = my.hostname.com what should my domainname = to if there is none. If I do require a domain name how to I create one? I need to be able to access e-mail from external clients.
