CentOS 5 :: One Centos 5.5 But 2 Different Start-up GUIs?
Jun 1, 2010
I move to Centos in October 2009 from Windoze and machines with 36 bit words. I now have 3 servers with Centos 5.5, 5.5. and 5.2 plus a laptop with 5.4 and am currently trying to put Centos on a 10.2" Netbook running Win XP.
On two 5.5 servers I notice a different graphical start-up process. One starts, from the text announcement "Centos 5.5 Final" with a blue Centos screen. If one displays the text it is shown with a thick blue Centos coloured border. The other starts up with text and stays in text mode until it has displayed the text log-in prompt and then after a few seconds presents the Centos GUI log-in screen.
My question is how can I make both servers, both ostensibly running the identical operating system, behave identically ?

I installed CentOS 5.6 and there was an error, so once it finished, I reburned the cds and installed it again. Now When I start up the cpu, GNU Grub comes up. Version 0.97 (640K lower/2096864K upper memory). How do I get the OS to start up. When i type in boot, I get error 8: Kernel must be loaded before booting".[Moderator edit: Fixed tyop in Subject.]

I just started setting up a linux box in the office...I have some experience with ssh commands but not setting up a linux system and stuff.The box is connected to our network but I have no clue how to make windows & osx talk with it. How can I go by doing that and also setting up an apache server to be able to connect through network. Right now I have apache/linux/mysql running it works when i go to localhost, but I would also like to let all the computers in office to access it. I would guess that will deal with virtual host which I know how to setup. I just need to setup an IP.

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 !
DHCPD.CONF

ignore client-updates;

Problems with xen 3.1.2 creating and installing domU CentOS 5.5 I am trying to do a virt-install --prompt --paravirt, and the install error out while trying to download install RPMs. I have googled for xen centos virt-install and various permutations. I have found similar howtos for 5.4 and 5.3, but they resulted in the same outcome. I did find several posts with similar issues, but no solution was posted.[URL]..

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.

I just installed a CentOS 5.4 x 64 on a customer's server last Saturday. I use lpr/lpd to print through this server to our network printers.
yum install cups-lpd
Edit /etc/xinetd.d/cups-lpd: disable = no
I did several restarts on /etc/rc.d/init.d/cups. I even did a "kill -SIGHUP 0" and a "kill -SIGHUP pid_xinetd". No joy. I finally gave up and rebooted: joy. Shades of Windows.
What did I miss? How do I start cup-lpd after yum without rebooting.

I have a CentOS 5 machine here, running Gnome. It has the proprietary ati screen driver, driving twin monitors in Xinerama. I have it set to auto-login as me. It has worked fine for ages.
This morning when I booted it up, instead of getting my usual desktop, I got 2 completely black screens, with an X-shaped mouse cursor. The cursor will move between the two screens OK, so I guess X has started, but I have no display manager. Or something. I have never really understood how X starts up, so I am now at a total loss as to how to find out what is wrong, and fix it. I can get to a login prompt by pressing Ctrl-Alt-F2, but I'm not sure which files to mess with when I get there. I have studied the X log in /var/log/messages, but there are no errors in there.

I'm a freelance now. so i installed CentOS in a portable hard disk for the convenient i move to new place and start my job.
But i found the grub of CentOS is installed on ...uhm... my Computer(?)...actually on my first Hard Disk(start up windows with MBR). and maybe the data of grub was installed on my portable hd. so i can't start CentOS on another computer and i even can't start windows without portable device...
so... is there any way to start up this OS without GRUB? or where should i pay more attention to when setting up to let CentOS could be moveable?

I have a machine running Centos and hosting 3 KVM VM also running Centos. After applying upgrade C 5.6 to host and to VMs one of my machines does not start with nwfilter option enabled in it's domain definition. Only following error is visible on console:

Before upgrade everything worked as expected. Packages iptables ( enabled ) and ebtables ( not enabled ) are installed on host. SELinux is disabled.

I have installed Tomcat 5.5 on a server with Centos 5.2. I can start Tomcat from command line with:
/var/lib/tomcat5/bin/catalina.sh start but if I add the command to /etc/rc.local Tomcat don't start on boot, I need to login and manually start. I have add other services to the /etc/rc.local file (mysql and apache) and all start with no problem. Only Tomcat failed to start on boot.
I added the JAVA_HOME to /root/.bashrc:
export JAVA_HOME=/usr/lib/jdk
export PATH=$JAVA_HOME/bin:$PATH
export CATALINA_HOME=/var/lib/tomcat5
export CATALINA_BASE=/var/lib/tomcat5
I have tried many different things I found on the net, but nothing worked for me.

since I upgraded to firefox 3.6 the program doesn't start up if I have any add-ons enabled.
The program starts fine with add-ons installed, but only starts up once as soon as any off them are enabled. Even normal add-ons like xmarks and adblock give problems.
