Red Hat / Fedora :: How To Stop DHCPD Service During Boot
Jul 19, 2010
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 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: in your dhcpd.conf file for the network segment 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:

I am trying to setup LDAP server on Ubuntu 10.04 and am sticking to the old /etc/ldap/slapd.conf file configuration.
I had to comment ldapi:/// from /etc/default/slapd since it was giving 'Address already in use error'. Also had to juggle with pid directory and file issues
After that I was able to start the slapd daemon (service slapd start) but now I am running into multiple issues:
1. Can't stop the service with service slapd stop
Code: ## Service stop returns 0, maybe because start-stop-daemon is not giving error #service slapd stop Stopping OpenLDAP: slapd. # echo $? 0
Will switching to BDB database resolve this ?Also can't I slapcat at non-root user ??
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'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 am new in configuring named.I want to set my firewall (Fedora 11) as a name server. The local domain is a Windows domain. I'd like internal users translate domain name into IP on this server when they go to the internet. After reading some posts on the web, I set up named as below. It seems the named does the job but with some problems.
1) When I start the server, I couldn't find the named process even if the file "named" is in /etc/init.d. I can browse Internet on the server with domain name (DNS works locally). But internal users couldn't get the domain name translated. If I shutdown the server at this stage, it will shutdown within 1 minute.
2) If I run "service named start" after the server boot up, I see process "named" and named work okay. Both internal user and local host can browse Internet with domain name. However, any command starting with "service named" has no response after this, such as "service named status" or "service named stop". I can see it shows "stopping named" and this last forever. I have to kill the process then restart named server so that named may run again.
3) If I shutdown the server now, it will take 4-5 minute instead of 1 minute in 1). The shutdown stuck at "shutdown named" for 4 minutes. Even if I kill process named before the shutdown, it will take 4-5 minutes.
It took me a week on this issue. I appreciate if you could take a look my configure files and guide me through this.
whats the difference between restarting/stopping apache using 'service httpd restart/stop' and apachectl restart/stop. I know that using 'service httpd restart' is actually a script in /etc/init.d/httpd but what about apachectl?
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?
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
clafiry what this means? It is in my secure log file: xinetd[5544]: START: smtp pid=6574 from=xx.xx.xx.xx xinetd[5544]: START: ftp pid=6465 from=xx.xx.xx.xxThey are repeated in my secure log hundreds of times, one every second or so.Also how can I stop my ftp and smtp service? Tried the usuals:service ftpd stop/etc/init.d/proftpd stopIt's a Fedora server.
I have setup a backup system on a NFS Server, and everything is working fine.Then, I decided to make changes to my backup script, and accidentally, I turned off both the NFS Server and Client without unmounting first.The NFS Server is working fine, but the client is having a problem. I cannot shutdown the nfs service. Here is what I get when I type "service nfs restart":
Shutting down NFS mountd: [ OK ] Shutting down NFS daemon: [ OK ] Shutting down NFS quotas: [ OK ]

I need a services viewer/start/stopper for slack 13.Htop is OK but want a easier-to-use GUI like in Gnome,etc.However, I am using JWM and so need an app that is not too heavily connected to a desktop like KDE/Gnome.
I'm trying to install Nvidia drivers 190.53 on my karmic with a Nvidia 9500GT. I've downloaded the file from the Nvidia website. I've done this before on previous installations and everything went fine, however, with karmic turning off the xserver is a bit of a trick.
/etc/init.d/gdm stop doesn't work sudo service gdm stop doesn't work sudo killall gdm doesn't work.
After I run sh ./NVIDIA-linux-x86-190.53-pkg1.run a notice pops up and tells me I'm running x and I need to exit out. I thought I did. I've looked at the instructions on the Nvidia website, but I don't remember it being that complicated before and am a little nervous about removing files I don't know what they do.
I am using debian squeeze server with asterisk 1.6 installed and configured.my problem is non root users need to access the server using ssh and restart asterisk server after making changes in asterisk configuration files.As of now i am giving root username/password for this process (i know it is not at all a good idea) .now how can i create a username and configure it which can only access and modify asterisk configuration files and restart asterisk server without any other privileges.
I have recently installed Centos 5.4 on a server with 3 network cards. I am trying to enable IP forwarding which has been successful by executing the following command:
echo 1 > /proc/sys/net/ipv4/ip_forward
I tried to make this permanent by adding net.ipv4.conf.default.forwarding=1 to the /etc/sysctl.conf file.
When I restart the network service I get the following code...
I am using # uname -rmi 2.6.18-194.26.1.el5PAE i686 i386
# cat /etc/*release* cat: /etc/lsb-release.d: Is a directory Red Hat Enterprise Linux Server release 5 (Tikanga) CentOS release 5.5 (Final)
I have noticed that after few days of ideal system it will stop its network interface. To resolve this I have to login to the machine it self and then issue # service network start Is this a feature. If this is not a feature then what is this. As an workaround I am thinking of adding service network restart in cron tab for everyday in night when I am not using it.
