CentOS 5 Server :: DHCPD Doesn't Start - How To Make It Start
Sep 2, 2010
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?
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 a mysql database and i use it with apache for my webpages. And I guess it dosen't start when the computer starts so I have to manually start it with "sudo /etc/init.d/mysql start" This returns fail so i went to '/var/run/mysqld/' and the folder was empty. I don't know if this is the problem or not. How can I fix this?
I did a clean install of Ubuntu 11.04 64bit and the start up time is abnormally slow. If I start up the computer and don't press anything, the start up time is 30 minutes but it usually doesn't start up at all. It just boots into a purple screen, no splash, then it sits there and the computer doesn't have any loading lights flashing.
I had a similar problem with 10.10, but I assumed it would go away when I did a clean install of 11.04.
I can't get a read out of what's going wrong because when I press Esc it doesn't display anything, though weirdly it can sometimes get the start up process moving. I have also found that pressing enter really fast can sometimes help and something that seems completely oxymoronic, if I press the power button while it's starting up that can make it work, but nothing works every time.
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.
Just for information in case if it is important to start dhcpd and named: Sep 16 20:26:44 LINUX-SRV named: nss_ldap: could not search LDAP server - Server is unavailable Sep 16 20:26:44 LINUX-SRV named: 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've made a big update of almost 300Mb.I'had a working DNS server.Now, when i boot the box, named works and it resolves all the clients.If i make any change (enter a new client for example) and of course i restart named (service named restart), named stop but does not start again !!!In order to get a working named, i 'm obliged to reboot the box?
I installed CentOS 5.3 without major problems, and customized the installation to my heart's content, but I still do not have flash plugin active when I first open firefox. I have to close the first firefox window and from the second instance of firefox, the flash plugin works without any problem.
I've got an install of CentOS 5.3 in a VM which was installed without X or Gnome.I've added X (yum groupinstall 'X Window System') and Gnome (yum groupinstall 'GNOME Desktop Environment) and can now run startx no problem.However on boot I get a command line login rather than the graphical login screen one normally gets if Gnome is included at install time.What do I need to do to get the graphical login after boot?
I'm trying to move a mysql 5.1.50-community InnoDB database from one location to another.When starting the service I get:Starting MySQL.Manager of pid-file quit without updating file [FAILED]I've searched for a way to do this but I can only find people who describe what I've just done.
Since upgrading from Wheezy to Jessie I have not been able to start the MySQL-server. When I do a "systemctl start mysql" I get the following answer on the console:
Job for mysql.service failed. See 'systemctl status mysql.service' and 'journalctl -xn' for details. Entering 'systemctl status mysql.service' the answer is: ● mysql.service - LSB: Start and stop the mysql database server daemon Loaded: loaded (/etc/init.d/mysql) Active: failed (Result: exit-code) since Don 2015-06-18 18:35:41 CEST; 4min 1s ago Process: 11272 ExecStart=/etc/init.d/mysql start (code=exited, status=1/FAILURE)
syslog and hostname.err don't show any pertinent messages.
Recently i upgraded my laptop from ubuntu 9.10 to 10.04 but alas! after the upgrade i don't get anything, just the 10.04 boot up screen and my cursor after some time. when i run it in recovery mode and tried to startx from there , it gave me a message " no protocol defined " now i can only access my system in failsafe x mod. code...
I need help adding a nohup command in this command line: su - rhx12 -c "/rhythx/rhythx/bin start /rhythx/rhyth" When I execute the script using root on the command line it works fine. But, when I reboot the server the process doesn't start. This script will go into the etc/init.d and rc2.d directory.
#!/bin/bash case $i in start) su - rhx12 -c "/rhythx/rhythx/bin start /rhythx/rhythx" ;;
I am trying to make start an iptables.cf script on my server.
I have copied it into /etc/init.d/ And try to make it load with /etc/init.d/iptables.cf start Then "not permission" (I was the root then). So, sudo /etc/init.d/iptables.cf start Then, "command not found".
i am currently trying to install vsFTP onto my new linux server and btw i just started using linux today this is my first time using linux so i got the ftp installed good it got downloaded and everything then i went to open a port for my server for vsFTP i used this comand to open it "-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT" then i closed it by pressing ESC then :wq! and it brought me back to my comand line again so now when i try to start the ip table thing with the comand "service iptables start" then when i execute that comand putty respondes with this "Applying iptables firewall rules: iptables-restore: line 1 failed [FAILED]"
I have an old computer (Pentium 4) without a monitor. To make the most of it I installed Ubuntu server on it and have been using it for almost a year. A couple of months ago I don't really recall what I did but since then it doesn't start-up unless a monitor was plugged in.
I've tried pinging it but it doesn't respond when no monitor is plugged in. meaning it's not even booting correctly.
I'd like to know what the problem is and how to fix it. And I'd really appreciate any help in diagnosing the problem. I just don't know where to start.
I'm running CentOS 5.4. I rebooted the machine for the first time in at least a month or so. I reboot into runlevel 3 (no X11). Things seem fine. But when I login and try to start X with "startx", the screen goes blank. X doesn't appear to start. In fact, the only thing I can do is reboot the machine and start over. This is really annoying.
