I'm planning on having a play with Ubuntu server. I'm running it on VMWare 7.
I installed Ubuntu server, after that i proceeded to update it.
sudo apt-get update
sudo apt-get upgrade
sudo reboot
After the reboot it just boots into a black screen with a blinking cursor.
I can boot into recovery mode if i hold down shift and i tried to follow these instructions for repairing GRUB.
I've been running my little server at home for a few months now, and I've noticed that Webmin has detected that I'm in need of over 100 updates. I'm a bit scared to run the updates because everything is working just fine right now, but a part of me still wants to run some of the updates.Now I know backing up the server would be a good idea to do before this happens. This server is a media server with videos, music and pictures taking up the majority of the hard drive space on the server. I just have one partition on the server, outside of the swap partition. I would like to back up everything on the server except the videos, music, and pictures, because if even an update messes with the server, I could always retrieve those, and the external hard drive I'm going to back up to wont be big enough to hold everything anyways.
if I were to backup up everything except for those directories that hold my videos, music, and pictures, and something were to go wrong, if I were to restore all of those, would I then be back to the state my system was at when I backed up? I've never done a back up and restore in a linux environment before. I just want to make sure that just doing that will be enough, because the last thing I want to do is hose my server after taking several weeks to get it to the working state that its at.
Could someone pls help me out on why my FC box (which is the Internet Gateway) is not updating AVG clients which are all XP OS.

I get about halfway through, to this command:
sudo ldapadd -x -D cn=admin,dc=example,dc=com -W -f frontend.example.com.ldif
When it asks me to "Enter LDAP Password:" and nothing I have tried works. I thought it might have been "olcRootPW: secret" set in the backend file in the step before, but that isn't working.
I recently tried to clone a RHEL 4 system and migrate it to some different hardware (IBM Blade to an IBM x3650M2 rack mount). I'm getting an error when it tries to boot up. It gets past the grub part, but then errors out quickly with this error code...
I've done this before, but the other system I migrated didn't have a separate "/" and "/boot" partition. I think this may be why it's having an issue. It seems like "/boot" is actually /dev/sda1 and "/" is /dev/sda2 (from booting up RHEL rescue disk). I've tried changing fstab and grub.conf, but I think I may be missing something.
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'
From: [url]
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?

I'm running a virtualised backupserver. This makes backups to an LVM volume on the host. /dev/mapper/system-backupserver is put through as a block device to the KVM-based, libvirt-managed backupserver and there it's mounted (obviously) rw.
I've also mounted the same volume, as ro, on the host, so as to get at my backups more easily. So now the same partition is mounted on two different machines, both thinking they've got sole access.
Now when the backupserver VM alters the contents of this partition, it sees this happening normally on its df report, but on the host machine, this remains mostly unseen. I tried doing a mount -o remount, but that doesn't help, although umount/mount will do it.
Meanwhile I seem to be able to get at all the data just fine, and it's just the total used/free that gets out of whack. Is there any way to regenerate/reread those totals without doing a full umount/mount cycle?
With 10.04 I can't stop SSH anymore by running "/etc/init.d/ssh stop". I get an "OK" after executing it but it doesn't actually do anything.

I've installed Ubuntu server and got everything setup pretty well.My problem is apache.I put my website in /var/www and changed the security on the files to allow them to be executed by other, which is what I finally discovered was my first problem (access denied). But now whenever.I go in and edit my page, the changes aren't reflected on the site unless I completely restart apache.I know I'm doing something wrong because I used to pay for a host and every time I edited a page, it was instantly updated on the site. Could one of you gurus tell me where I screwed up?

I just installed 10.04 i386 Server(release version)last night on an older IBM workstation (sorry, for the life of me can't remember model and I'm at work now); P4 2.4, 512Mb RAM, generic Intel graphics. This was a base install (aside from OpenSSH) with no window mgr. The HDD was wiped during the install and GRUB2 wrote to the MBR.
The install went smoothly, and on the soft reboot after the install I got a shell and was able to login, etc. and even SSH in.I unplugged the machine, moved it, booted, and got a cursor in the upper-left of the screen for about 3 seconds, and then the monitor would enter power save mode. (I tried 2 different models of monitor). While the cursor was on the screen the HDD access LED was blinking with activity, but that would stop right before the screen would enter standby. Tried a few reboots with the same result.
I'm thinking this is not a video driver issue (as similar threads have suggested),because the splash screen for the install disc renders properly and on the first successful boot the shell rendered appropriately at a high resolution.I can hold down shift to enter the GRUB2 menu, which also renders at a higher-than-text resolution and is defaulted / displays the correct options.
Most other threads with a similar yet non-video issue centered around GRUB2 issues with a dual-boot machine, which mine is not.I did go in via rescue mode (off the install CD -- the rescue option of the GRUB menu has the same result as a standard boot), and checked that my grub.cfg was correct, and I ran grub-install to no avail, and also ran grub-mkconfig on a subsequent boot to no avail, yet the grub.cfg generated appeared identical to the original generated during install.
The partition/file system is default layout.
20 Gb IDE (/dev/sda)
/dev/sda1 /boot ext2
/dev/sda2 Ext

I'd be happy to give more info if someone has a troubleshooting direction in which to go.
I'm trying to track down a problem with my server. Basically, I can get it to boot with a LiveCD and do rescue stuff with it - I just can no longer get it to boot. I've been slowly working my way through all of the error messages that come up during the boot process, and knocking them off one by one. Right now, they're fairly minor.
I'm trying to find out what the big issue is by looking at the logs. The last thing that it does is bring up apache2, says [OK] and then hangs. I've tried to do ls -lustR on /var/log to see what's the last log touched, and that's syslog or boot.log, but the last entry says something along the lines of Apache2 is up and running.
Where else should I look?
After a powercut in the middle of the night (UPS battery also ran out before power came back) my server is now hanging on boot.This is where it gets, and it just hangs indefinitely:

Now I've upgrade the server to Karmic Koala (9.10) and it just stopped working.
1) The clients have PXE NICs
2) They get the proper IPs from the DHCP server and respond appropriately to changes in the DHCP configuration files.
3) DHCP server also points the clients to
filename=/ltsp/i386/pxelinux.0
4) When the clients try to download the pxelinux.0 over tftp they just timeout
5) /etc/inetd.conf has an entry like
tftp dgram udp wait root /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot
6) The file /var/lib/tftpboot/ltsp/i386/pxelinux.0 exists on the server
I'm lost at all these configuration files and protocols.

Here's the problem -- DHCP wont start and throws the error "Can't create PID file /var/run/dhcpd.pid: Permission denied." Somewhere I found a post that indicated that the following corrected the issue (I dont really know why):
ln -s /var/run/dhcp3-server/dhcpd.pid /var/run/dhcpd.pid
dhcpd3 -cf /etc/dhcp3/dhcpd.conf eth1
When I do the above DHCP will start (in theory, at least no erros are thrown). But if I ask DHCP to restart, it will stop, but not restart. And the error is "No subnet declaration for eth1 (192.168.3.2)"

I am trying to build my second home file server after building an experimental x386 unit.
Gigabyte x64 Motherboard with 3core processor and 4GB RAM
10 1.5TB SATA HDD (Mostly WD15EARS and W15EADS)
2 2TB SATA2 HDD (WD20EARS)
I want to create a RAID 6 Array of the 10 1.5TB drives and (1.5 TB partitons of the 2 TB drives) the remaining 0.5TB of the 2 TB drives will be used for RAID 1 arrays (SWAP, root and usr)
When i partition the drives the 1.5 TB drives can be Primary or Logical. The 2 TB drives do not give me this option.
For the 2 TB drives:
- i can partition into 8GB Swap, 20 GB root, 474GB usr and 1.5TB RAID6.
- When i select (Physical partition for RAID) I CANNOT change the Bootable FLag to ON. It always stay OFF. If i use other file systems such as exf4 it can be changed to ON.
- when i continue with the installation it fails while installing GRUB.
Questions:
Why does my 2TB drive not allow me the choice of Primary or Logical?
Is the Bootable Flag = Off the reason GRUB will not install?
How can I achieve my goal of using the 2TB drives for RAID 1 and RAID 6
I'm using Ubuntu 10.04 64 bit Server Edition here. I'm running Apache as a web server. I just found that Apache is not logging to access.log and error.log anymore.
But the service is running well. Log parameter at /etc/apache2/apache2.conf seems to be OK. Here's the line :
ErrorLog /var/log/apache2/error.log
LogLevel warn
CustomLog /var/log/apache2/other_vhosts_access.log vhost_combined
I already tried restart the server, but no luck. Is there any place should I check?
I'm having a problem with NFS. I'm trying to mount /home, which is on the server, to the client nodes. The server is currently running FC14 (64 bit) and I'm in the process of updating all the clients nodes to the same OS. Currently, all the client nodes are running FC8 (32 bit) and are capable of mounting /home on the server. However, the one client node that I have updated to FC14 is having problems mounting /home. I can ssh to the node with no problem however I get the following message:
Could not chdir to home directory /home/myuserid: Permission denied. Now, if I excute the following command: "sudo mount -a" I get no errors and now I can see my home directory.
I'd like to eliminate anything unnecessary from my Ubuntu Server box (on a Compact Flash IDE drive) and set it up to boot into RAM. I've seen ways of getting a live CD to do this and seen other distributions that are designed to do this, but since I'm familiar with Ubuntu, I'd like to be able to get rid of my swap space and make the existing installation boot to RAM.

View 1 Replies View RelatedI'm having an odd problem with Server 10.04. I have two interfaces but only one interface is brought up on boot - and it's not always the same interface. Usually eth0 fails and eth1 comes up fine, but sometimes eth1 fails and eth0 comes up. I'm using the same config that was previously used on Server 8.04, but never had this problem on 8.04.
/etc/network/interfaces:
Code:
# The loopback network interface
auto lo
iface lo inet loopback[code]....
Once the system has booted, if I run /etc/init.d/networking restart, then both interfaces come up fine. However, having read that this is now an upstart, I also tried service networking restart, but get:
Code:
restart: Unknown instance:
Don't know if that's significant or not.
Cannot find a single problem with networking reported in log files, other than bound services failing to start as a result of the interface not being up (dansguardian, squid, dhcp which are all bound to eth0, and therefore fail when eth0 doesn't come up. And when eth1 doesn't come up, the only process that fails to run is clamav-freshclam). Although at one point I did see something about interfaces being renamed which seemed a little odd.
I could just have networking restarted automatically once booted, but this obviously isn't a solution to whatever is causing the problem. There is quite a bit running on the server: Samba/LDAP domain controller with roaming profiles, squid & dansguardian with LDAP auth, postfix & dovecot with LDAP auth, mailscanner, dhcp & ddns, strict iptables policy with nat... so I'm not sure if any of those could have any bearing on interfaces?
I just installed Ubuntu 11.04 server edition into vmware workstation. Everything works well and I can even set-up a LAMP server.

So I tried installing the nvidia drivers for my GeForce 330M using Jockey after I first installed 10.10, but it did not make it so my desktop was not bigger than my screen. So, I blacklisted nouveau by creating a text file which had in it:
blacklist nouveau
options nouveau modeset=0
Then I saved the file as disable-nouveau.conf, then chown(ed) it to be owned by root, and moved it to /etc/modprobe.d/
I then installed the driver for my nvidia card, and everything worked perfectly. But after installing the updates listed in the update manager, my computer won't even boot to the GUI desktop, it just hangs. I can still access the command line, but when press <ctrl-alt-F7>.
All I see is this:
fsck from util-linux-ng 2.17.2

Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox
*Setting sensors limits
speech-dispatcher disabled; edit /etc/default/speech-dispatcher
*Starting the Windbind daemon winbind
And that's it. It just hangs there. Like I said, I can still access the command line with <ctrl-alt-F1>, but I have no idea how to get Gnome I guess to display?
I installed netatalk for Linux in Fedora 10. I managed to get the service starting correctly at every boot and from Linux side everything looks good. I even manged to tweak avahi-daemon to advertise my server on the network so would show in Finder sidebar (with a snazy tux icon). But when I try to connect to the server it asks me for username and password (as it should), but my password doesn't work. I changed my password, I even gave it a simple one to rule out possibility of "fat-finger"-ing. No success.
