Server :: Running Cobbler On CentOS Machine Hangs?
Nov 16, 2010
Using the EPEL Repository, I went in and installed Cobbler to my DHCP/Gateway box.Everything went smoothly on the installation front. I went ahead and modified the cobbler settings file (/etc/cobbler/settings) to point to my server IP (same box), and then got tftp running properly. Now here's the problem.Normally, you need to run `cobbler check` to find issues and correct them. I run that, and all I get is blank. Nothing. It just hangs at the prompt until I kill it using CTRL+C.When I CTRL+C from the hanging, it states "cobblerd does not appear to be running/accessible"...
Code:
[root@PalaceRedirect ~]# service cobblerd status
cobblerd (pid 6991) is running...
I had just put the last touch on a snort, mysql, apache, barnyard, base isntall to CentOs 5.3. I noticed that ifconfig displayed an odd virtual nic, and I wanted as little running on this machine as possible. I don't remember specifying that I wanted XEN installed. And on the old lowend machine that is powering this server, Virtualization was the last thing I wanted running on it. I did a google, discovered that the way to remove XEN completely (yum uninstall xen' only removed 'xen' but still, oddly, xen was running after a reboot. Talk about perplexing.
I have managed to configure a wireles PCI card on CentOS 5.3 and it seems to work fine. It is a off brand (Hercules) with a Ralink RT61 chipset. I installed the most current driver (RT2501PCI/mPCI/CB(RT61:RT2561/RT2561S/RT2661) from the rt2x00 Open Source Project. I now have a question that might be very simple for one or more of you to answer. When I issue the command "shutdown -h now", the machine starts to come down and brings down eth0 cleanly, but when it attempts to bring down wlan0, the machine hangs and never brings down the interface OR powers off the box. The only way to complete the power off is to "hard" power off the machine.
I installed Tomcat5.5.23 on CentOS5.2 running on Sun xVM Virtual Box2.1.2. When i try to view Tomcat( Running in Vitual Centos)'s home page in the web browser of Host( XP sp2) am getting the "Connection Time out" error.. How to resolve this problem.
I would like to build a bootable system image on an attached hard disk on a running CentOS machine.The hard disk would be moved to a headless server, where only SSH access would be available. It seems that all the documented install methods assume that the installation runs on the taget machine. In this case, I would like to create a bootable system image of CentOS on a running host system. The new install mage would generally have a newer version of CentOS than the running host system where the image is created. Also, I would prefer to do a text-based install.
The reason for all this is that I have network access to several remote machines. I can ask disks to be moved between machines, but I have no physical access. In order to do software testing, I would like to have several system disks with different installed CentOS versions. It would be easer if I could build the system disks on one single machine. The hardware an all machines is very nearly identical.
I've started facing the weirdest problem. I have to restart the ethernet interface a couple of times a day and everytime i do that the server locks up completely and i have to hard reboot it.info: recently shifted to a new server, all new components and new installation, OS version CentOS 5.6
I've installed CentOS 5.3 on a machine, and I need a Samba version 3.2 or higher. Since 3.4 is out, I thought I'd grab that. But, "yum list|grep samba" gives me only version 3.0.33. Is there a package of Samba I can grab that will upgrade the 3.0 installation so that I don't have two laying around? If not and I need to compile from source, do you have any suggestions for what arguments I should give configure? I'm not used to Linux coming from the BSD world
I have an old unuseable computer at home that became useless after a hard disk failure. I don't want to spend money on buying a new PATA IDE HDD for it, so I was wondering if I can use a PXE boot server on my notebook (using a virtual machine with Linux) and boot a Linux on the old machine with PXE without using Hard Disk. It is possible? Do I will need to make some extra configuration or use some specific enviroment do do this?
I have Centos 5 Installation with following Linux ipmpls.mobilink.net.pk 2.6.18-8.el5xen #1 SMP Fri Jan 26 14:42:21 EST 2007 i686 i686 i386 GNU/Linux. I have Nagios running on it for monitoring switches. It also runs postfix to give email alerts in case of a switch is unreachable. The problem is that the server hangs for a minute and returns to normal operation. During this period if a switch is polled it cannot be reached and hence Nagios shows the Flapping state on the switches. I need to understand as to why the server hangs
Problem : centos 5.3 hangs while remotely copying data onto this server.
I have A centos 5.3 x86 Version installed on Xeon Quad core , running on 8 GB DDR2 RAM, RAID 1 confgured on SATA drives. this was old installation copy and It has many more things running on it.Therfore, I can't just reinstall it.
I have setup SAMBA PDC + ldap on it. I encounter that system hangs when I copy data into this server from LAN computers.
My troubleshooting steps :
1. I have checked for network issue , My network works fine when I transfer data between other LAN compuers.
2. Even I have tried confguring seprate LAN....
3. I thought their might be some problem with my SAMBA configuration, therefore I did data transfer from sftp .
I am attempting to upgrade a system from 4.7 to 5.2 using a (now) DVD drive attached to the onboard IDE. Originally I had tried using a remote NFS image and a USB stick but I thought maybe there was a problem with the image. I can get up to the point of the installation of selecting the keyboard for the system and then it freezes and never goes any further. It doesn't appear to be a kernel panic since I can still switch between consoles.
I've got an MSI K9NGM2-FID with 14 drives in it. It serves as a file server for our backup server. It's got a secondary 4 port Silicon Image SII 3114 SATA card using the sata_sil module, and an old IDE Promise FastTrak TX2000. Technically I could have 16 drives but the 750W PS is walking the fine line on tripping it's self-breaker with the 14 drives and 7 fans. I would like to NOT have to disconnect all of this to do the upgrade.
I thought maybe that running the install using the "noprobe" option would help so it didn't detect and load the modules for the Silicon Image or the Promise cards and detect all of the drives but it still gets stuck on the step after selecting the keyboard. The installation info console and the dmesg console don't really provide any useful information. The installation console says:
INFO : moving (1) to step welcome INFO : moving (1) to step language INFO : moving (1) to step keyboard INFO : moving (1) to step findrootparts
And the last lines of the dmesg console says:
<6>device-mapper: multipath: version 1.0.5 loaded <6>device-mapper: multipath round-robin: version 1.0.0 loaded <6>device-mapper: multipath emc: version 0.0.3 loaded
Is there a hidden "debug" option that will turn on a lot of extra logging?
I'm know very little about Linux but decided to set up a machine running Drupal CMS on a Debian machine and it won't go. The folks at Drupal have tried to help but it seems the Debian OS won't do it's PHP thing for Drupal.
That means i'll have to start at the START I guess.
how to become a master of Linux if one is starting from ABC (I can add and subtract, that's what it feels like)
I have installed CentOS on a VMwareWorktation and that CentOS, i also install VMware Server (suscess) and setup a guest OS that, but i start this Guest OS, an error show "You may not power virtual machine in virtual machine"...
Cobbler import does not seem to work as described here:[URL]..I have selinux disabled.

The following are potential configuration items that you may want to fix:
1 : since iptables may be running, ensure 69, 80, and 25151 are unblocked 2 : debmirror package is not installed, it will be required to manage debian deployments and repositories
Restart cobblerd and then run 'cobbler sync' to apply changes. The listed ports are open in iptables, and I do not need to manage a debian deployment.
I cant understand how to sort out from this problem, while check the cobbler boot server, from the command cobbler check follwing error comes out , i dont understand how to fix it
1 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one Restart cobblerd and then run 'cobbler sync' to apply changes.
I have set up a 5.5 installation on a Virtual box VM. The Virtualbox (not for the VM) network preferences have DHCP Server disabled and IPV address and the network mask I believe are valid for my home network. My VM is up and running and it has gotten an IP address from my home router and everything seems fine. From any machine in my house I can ssh into my centos installation. I went ahead and started up the httpd service and the website is up. IOW, I can see it from my centos box - when I navigate to http://localhost However, I cannot see it from any other machine on the net. The IP address of the centos bos is 192.168.0.141. From the centos I can do a ttp://192.168.0.141 and see the Apache 2 test Page. I can see that from anywhere else. Although I can ssh to that machine.
installing my APC Back-UPS ES 350. I am using CentOS 5 KDE setup as a DNS Resolving Caching Name Server, I wanted increase speeds and privacy since I got a letter and didn't like that not one bit, a tv show but whatever. It is very secure now, using peerblock with Iblock List subscribed to for the one year and it is so secure that I have to disable peerblock if I want to use online banking and what not.
setup the APC unit, haven't experienced APC and CentOS is new to me, I didn't want to buy a windows server, so I used BIND instead and well I love CentOS, can't wait to really understand it a lot better, also logging into root is so nice and easy vs Ubuntu, very cool.
I also do not have a DD-WRT supported router nor a Docsis 3 modem, docsis 2, I believe this should give me a lot more speed. currently I just get 11-17Mbps, I am hoping this will bump me back up to 35-37Mbps which I get off and on but unstable.
For the first time in installed and configured centos-ds from this HowTos and from the manuals.It is running nicely but disabled my httpd.Is it not possible to run directory service and httpd in the same machine
I installed the Centos 5.5 with XEN and put 03 virtual machines (Centos 5.5 too). I did this correctly, but I have a problem. In the virtual machine, I need update the kernel. I used "yum update kernel" and this is downloaded correctly and the menu.lst file is updated too, but the kernel not ran. I ran "grub-install /dev/sda" or "grub-install /dev/xvda" and received a error return. I read the device.map file and i ran "grub-install /dev/sde" and received a error return too.
The errors: [root@vm01 ~]# grub-install /dev/sda /dev/sda: Not found or not a block device. [root@vm01 ~]# grub-install /dev/sde /dev/sda1 does not have any corresponding BIOS drive. [root@vm01 ~]# grub-install /dev/xvda /dev/xvda: Not found or not a block device.
Can anyone point me in the direction of setting up shares for windows machines on centos. I have found a few document but never managed to get it up and running correctly. I need to be able to get access to subfolder etc for different users. Is there any way of doing it with some sort of gui?
I just installed VMware server 2.02 on a CentOS 5.4 machine. I tried to run 'vmware': it starts via my web browser (firefox) with xdg-open. Then, firefox displays this:
Connection Interrupted
The connection to the server was reset while the page was loading. The network link was interrupted while negotiating a connection. try again.
I'm running CentOS 5.5 x64 and have just installed VMWare Server 1. I am able to create a new Virtual Machine, but when I go to power on the VM in order to install the OS (windows server 2003), either the host crashes/reboots (with "Run in Debugging Mode" turned on) or the VM simply does not start (with that Debugging box unchecked) and in the log there is an error along the lines of VMware Server unrecoverable error (vmx)
I have installed CentOS 5.5 along with the Samba package. I have it configured (i believe), but when I try to access a share, it is not accepting my UN/PW. I have copied the smb.conf file from a working computer over to this one, but it is still not accepting my login. Anyone know of any other files I should check?
I have moved a working smb.conf file to this new box, and both computers have the same UN/PW's
I would like to connect via SSH or similar to my servers located in a remote DC from a laptop running centos5. I normally do this on a puter running dows, and using secureCRT. Just wondering if centos has something built in for this, or if there is some preferably free software I can get.
I have Centos 5.3 on our server When I log-in in webmin I have a message "Warning - Your system is actually running CentOS Linux version 5.3." In the next line I have a button "Update Detected Operating System" My question is Do I need to click the link and update Detected operating system? If I do, is it going to change any configuration on our server?
I am trying to set up samba in my CentOS virtual machine that is running on a Windows 7 host. I have found a tutorial in the How-Tos on this site but I'm not sure if they are exact and I'm paranoid about messing something up. The link to the tutorial is below. Is there anything that I should do different or anything that I should be aware of? Also, once this is set up, how do I transfer files between the two machines?
