I've set up a ubuntu server 8.04 with ntp-server. At boot time the ntp service is started, butCode:ntpq -pdelivers:No association ID's returned.I've set up the ntp the way to be able above my private network to use this as reference.If i restart ntp everything is fine.First i thought that the problem is that dhcp is started after ntp, but after changing the start-order in the runlevels this enigma remains.
View 2 RepliesI'm working on a (minecraft) server on some old hardware and started by installing a fresh copy of ubuntu server 11.04. After that I installed the minimal xfce system with the guide at [URL] . I've tried every trick I could find on to disable it from starting up, but it appears every time! Wierdly enough, it doesnt display any standard looking login screen, but instead displays this old looking login screen with a debian logo. Not sure how to get a screen shot of it. All I want is it to boot into a command line!

View 9 Replies View RelatedI'm running Ubuntu Server 11.04 on a home PC as a local-only file and web server for some private projects.After a few minutes Ubuntu will stop responding to the network and a cold reboot is required to re-enable the NIC.I've been able to stop the above occurring with a user logged in and constantly pinging the gateway, although this is obviously undesirable.
I read here and elsewhere that a fix is to set acpi=off in grub. I have done this but now instead Ubuntu will not boot and shows the message:
do_IRQ: 1.55 No irq handle for vector (irq -1)
Disabling IRQ #34
and hangs there indefinitely. The system will boot fine if I revert the changes but obviously the sleep problem remains.The BIOS does not have an option to disable ACPI, just select S1 or S3.Is there anything else I should be looking for in order to disable sleep? Otherwise the system is working fine, and when it's awake I haven't had any other trouble.
I 10.04 32bit server edition on a box I had lying around, set it up for samba+upnp, and everything was going great.
When rebooting, the server now turns the monitor off, and I'm not sure if anything's loading. I see the initial dell splash screen, and hear the hard drive start to run, and then the monitor goes into standby.
I tried booting up natty server on both a unetbootem usb flash drive install and on CD. I get the menu of options to install like Install Ubuntu Server, Install Ubuntu Server 9 expert install, Cloud, etc. Hitting install either the 1st or 2nd option leads to a black screen but not at a frozen state(I can still reboot with ctrl-alt-del). The server Im installing on is a ibm system-x rack with a single xeon and a raid5 already setup to be used for installation. Now Im back to using lucid 10.04.2 which I might consider upgrading through Update Manager since I cant get natty to boot correctly with a working display. Anyone having similar problems on Natty server stable release?Also as I post this, I dont see a ubuntu server prefix, maybe it should be added?

Networking is not exactly my strong suit, but I would like to get this up and running if at all possible.
server configuration: SCSI 36gig -> sdd; boot and root as it was first in the box;2 IDE hard drives -> sda/sdb for data; and1 SATA drive -> sdc for data.After upgrading to Lucid (not right away, but a bit later), it stopped booting:'Gave up waiting for root device.'ALERT! /dev/disk/by-uuid/........... does not exist. Dropping to a shell!(initramfs)Happily, pushing ^D let it resume booting, but it kept repeating. After some study, I found the Lucid release notes that said "if you upgrade to ext4, you have to manually update Grub". A quick check showed that sdd was now, indeed ext4 - nobody told me! And, why couldn't it update Grub by itself? But, I dutifully ran grub-install and life went back to normal.
Until last night, when I updated the kernel, etc. with apt-get and restarted, and grub dropped dead:More googling turned up this solution, which I used with an install CD:http://tinyurl.com/2dhswzzWhich worked, but it brought back the first problem, and running grub-install doesn't fix it. So, what do I do now?
I have a server running 64bit lucid and while trying to get a script to run on boot to start Davmail I appear to have broken something. I have webmin installed but I have been trying to do the majority of things via the command line. I now have davmail starting at boot but a lot of other services don't start anymore, including apache, mysql and webmin. Fortunately SSH still works and I can start apache and webmin from the command line without any problems.
View 1 Replies View RelatedI got myself a HP t5000 series Thin client to use on my LTSP 10.04. I changed the Bios to boot PxE. When i restart the thin client it asks for a DHCP and finds the LTSP-DHCP server all is good. Its got a IP address ok, the boot process starts. ok I get the Splash screen for Ubuntu. and all is going well. ok I no get a login screen. All is going very well. (As normal with Ubuntu). I can login all is good the login starts and i get the start up sound.But then where normally one would expect to get a desktop, one gets a login screen. Not knowing the full boot procses im not sure where to start to look. Knowing linux there would be a log file somewhere, that stores the LTSP Terminal Bootup/login process and would tell me where its stopping/failing.
The good news is that when i boot a fat client in all works ok and i an able to get in with a desktop.
How can I disable the startup for ubuntu's desktop during booting the system?I would like to start it manually.I tried to remove the /etc/init.d/gdm file but no help.

Here's exracted from ubuntu Grub2 document https://help.ubuntu.com/community/Grub2:
GRUB_HIDDEN_TIMEOUT=0 This setting determines how long a screen without the GRUB 2 menu will be displayed. While the screen is blank, the user can press any key to display the menu.The default behavior is to hide the menu if only one operating system is present. If a user with only Ubuntu wishes to display the menu, place a # symbol at the start of this line to disable the hidden menu feature.According to above information, I have tried to set below in order the show the menu:
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=false

Perty self explanitory, I'm trying to boot up ubunto server edition 10.10 from a USB stick (pen drive) and it works fine until step 3 when it says "Your installation CD-ROM couldn't be mounted. This probably means that the CD-ROM was not put in the drive. If so you can insert it and try again
Try again to mount the CD-ROM? <Yes> <No>"
I don't have an installation cd-rom! I put the .iso file onto a memory stick, inserted it into my old computer (which i will turn into a server later) , restarted it and got past the first two slides and got this error? Do I have to put the iso on a cd-rom?
I have been trying to accomplish this feat for about a week now, and I always seem to get a boot up error.
Here is how I call WinPe from my default file
Code:
We have done an installation on a blade server (HP) for RHEL4.5.
The server have an HP smart array 2200 controller and during installation it can see the controller and disks just fine.
The installation completes up to the point where the system needs to reboot , however after the reboot it does not start up again and get stuck at the message: "Trying to boot from drive c:"
We used the rescue option to mount the installation and cant find nythign wrong, even with the grub setup (except that it points to hd96 as its primary disk). we tried changing this to hd0 as well but still no luck.
After about 3 installations we are still not having any luck.
i found this video, and i really want to do the same. *newbie needs to learn [URL]...my question is, what need to be installed and how?
is there any specific configuration to make it works?
and will it work if i want to connect from Ubuntu to Fedora ?
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
this may seem a little odd, but I used my server to install Ubuntu on to an external hard drive. (long story short, the server won't recognize any internal hard disks with any type of video card installed. The video card works just fine when installed, and it will read both CDs/DVDs and USB drives just fine, it just refuses to even notice hard disks. I'm assuming an IRQ issue, but I've tried changing them with no success.) Having installed Ubuntu 10.04 on my external 250g hard disk, I attempted to boot it from the USB drive, since the system has that option. It tells me "error: out of disk" and goes to the Grub rescue prompt. Having followed multiple threads and advice posts, including on this forum, I was unable to resolve the issue. For s'n'gs, I hooked affore mentioned external hard disk to my laptop and tested it. Boots just fine. Then hooked it back to my server to see if it would boot. Still no dice [Just a side note, no the video card is not currently installed in said server, I was testing it to see if the thing would install and operate alright before I tested it with video card installed. Only ever make one change at a time, that way if something explodes, I know what caused it.] My initial objective was to get an operating system that would boot with the video card installed. Any ideas what might be going wrong here?
View 2 Replies View RelatedI own a rather large website/forum devoted to Scuba utilizing vBulletin. The problem is that its become INCREDIBLY slow as of late. I have three Ubuntu web servers under a single Ubuntu load balancer and they draw from a CentOS 5 DB server running MYSQL. Here are my concerns:
-I am thinking that they are all 32 bit rather than 64 bit.
-I am thinking that the problem is an IO issue.
I am trying to get a server to boot off the lan (pxe). I added a tftp server and tested it as operating successfully. I just plugged the pxe-server in and see the dhcp request/response as expected. The pxe-server then sends out an arp to the same address as the dhcp exchange, but the server never responds.
1. as the pxe-server already has info on the mac/ip-addr, why is it now sending another arp
2. why doesn't the server respond? I have most of my network setup the same way and the dhcp exchange is fine.
3. I'm guessing that the arp is triggered by the bootp exchange (next-server).
I do not have the server in the host table under that address.
127.0.0.1 localhost

Do I need to add 192.168.5.120 with a name to get arp to respond?

I changed the first line of /etc/fstab in an attempt to get rid of an annoying message "mount: unknown filesystem type 'static'". All I did was put a "#" on the first line .... changing the original from:

to:
#
# /etc/fstab: static file system information.

View 2 Replies View RelatedI seem to have a complex issue on my hands that i can't figure out. first, i wasn't able to get access to my LVM'd hard drives via SSH without half of the content being missing or locked out (read-only or unable to open at all). the problem then went up to being unable to boot up - all i got was a long slew of [100.1234] ata1.00: error messages (they eventually DO stop once they get to around 998.234234 or whatever, and then i can log in and it seems to be "stable").
Part way through this rebooting ordeal i realized / decided to make power-on-self-test stop and wait if it finds errors (via bios) - that showed me that my 750G SATA drive is "bad" and my two (older) 120G & 250G IDE drives are "ok". i then unplugged the SATA drive, rebooted, and didn't see those error messages. however, my LVM was still obviously not coming together (since LVM was made up of the 120G, 250G, and 750G drives)
So, now it seems:
a) I can't boot smoothly with all drives in place
b) I can't do anything with lvm if i remove the 750G sata
c) With all drives hooked up, i can wait 10mins for the errors to go away, but STILL can't do anything with lvm
d) I need to recover the lvm stuff so that i can nicely migrate ALL those files (1.1TB of it) onto a new 1.5TB drive and do away with lvm
This is all running ubuntu 7.10 server edition (32-bit version on a 64-bit computer). i DID post a question on the ubuntu forum as well but so far got no replies at all.
Here's a few pics of the booting process, with one or two "fail" lines showing.
I am running ubuntu server 10.10. It was running fine until I tried installing a second hdd to back up my desktop (xp) and laptop (win7). I was following this guide: [URL]. I formatted it first as ext3 then realised I need fat32 so reformatted as vfat. When I went to mount the drive I got a warning that started:
Code:
gksu:2400 Gtk-warning........
I rebooted using:
Code:
shutdown -r now
But when it restarted it stopped at a blank screen with a flashing 'underscore' in the top left corner. Where to go from here? Do I need to do a fresh install?
