Ubuntu Servers :: Disabling GUI From Init Scripts?
Jan 29, 2010
I have a headless Ubuntu computer which is primarily use as a server but which has Ubuntu desktop edition installed. I use X forwarding through SSH occasionally to use GUI programs so I am not looking to remove them. However, I would like to disable any GUI elements that would be started automatically when the computer is booted. Is the graphical login screen the only thing that would be run? or is nautilus, gnome-session etc. started as well? How would I go about removing the necessary entries from the init scripts?

How do you enable/disable the autostart of services. For example let's say I know I'm not gonna use apache and mysql for a while and don't want it to autostart anymore how do I disable it ?
And then once it is needed again how do you enable the autostart again ?

I'm running a server using ubuntu 10.04 x64. I want to disable access of groups to "bin" folder so they cannot execute commands.
[info: actually because of a bug in cPanel (the control panel I installed) Perl will give access to all hosting users to execute commands.]
So what I wanna do is to ban some groups on 'bin' folder, for example 'my_group1' and 'my_group2" cannot access bin but 'my_trusted_group' can access it. How is it possible?

I just installed ubuntu 10.04 on a pc... the server edition. i went to restart samba and it is not in the init.d directory. is there a different folder for server plateforms? cause im use to my 9.10 desktop edition.
also one more question, when i "ls" the /ect/ directory of course i cant see the whole thing because my monitor only shows the bottom of the file, is there a way to list it like the "more" commands, or possibly scroll up?

recently installed phpVirtualBox and VirtualBox on my 10.04 LTS ubuntu server it's getting annoying having to type
Code:
/usr/bin/vboxwebsrv -b --logfile /dev/null >/dev/null
every time i reboot the server
tried for hours to make an init.d script that will run it but failed..basically I just want it to automatically run the above command on every boot.

I have two ubuntu servers. I have upgraded them to 10.04. Now I have serious problems at startup: iscsitarget and heartbeat scripts do not start all the times I reboot.I have installed monit to try to start iscsitarget and heartbeat and guess what? It does not start too at boot.In one of the two server sometimes it also starts with ethernet cards swapped.

Has anyone got a working apache upstart script? I'm running 10.04, and want the nice supervision stuff from upstart to run my apache instance. I've googled (especially for things like replacement-initscripts) but not hit anything concrete.

I wrote a custom init script for a java application. The script resides in /etc/init.d and follows the convention for the init.d scripts. However, the script runs the java process as root. I need these processes to run as a non-root user. Is there a way besides using sudo or su in the script (seems inelegant), to run the script as a specific non-root user? Perhaps using a .conf file in /etc/init or a daemon wrapper? What would the Ubuntu way of doing this be?

I have the current disk setup :
disk1 :
Code:
sda:
(primary) sda1 ntfs
(primary) sda2 ext3 (mounted as / )[code]....
Before i set up the raid, but with this exact partitioning, the system booted perfectly. When i installed mdadm and created the raid1 mirroring on sda6 and sdb1, the init got screwed up, and all i get is a shell on initramfs, from where i can inspect that sda is binded on md, and cat /proc/mdstat tells me that i have an inactive sda[4].I can't mount the root partition (sda2), because it's busy (i suspect dmraid to lock it), which is, i guess, why init cannot be found.
I wonder if my error is to setup a raid array using a logical partition contained in an extended partition (but i hardly see why it would not work - but the sda bind and the sda[4] in mdstat seems to tell me that it does not), or it's just the initrd that is improperly configured. The other things that bothers me, is that changing the partition type of the raid partitions (fd to 0 - Empty), to disable raid autodetection, resulted in the same behavior on boot. Which might lead me again to think about configuration file problem instead of improper setup.The live cd doesn't not seem to recognize raid, so i can't inspect problems any further, but i could inspect system configuration, but i don't really know where to start.

We have a virtual XP machine on our fedora 11 install. I want to drop fedora 11 down to init3 (since its a server anyway) and everyone is worried about the windows virtual machine dying. What would happen to my windows virtual machine if I drop the host server to init 3?

I've been dual booting 10.10 with Windows7 for about a month. Today is the first time I've encountered a serious problem.
This morning, nothing functioned properly after trying to open several programs. The computer seemed to be "frozen", although the mouse was working fine.
I decided to reboot, but then encountered an even bigger problem.
It failed to boot and got this message: no init found. try passing init= bootarg
The problem now is that it requires a Live CD session and I keep getting this: GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)
In case it matters, I didn't install 10.10 from an ISO, I just upgraded from 10.04.

I installed squid on my machine, and for a while it was starting up automatically when the computer would turn on, and I would only have to reconfigure on ip-up for the new dns, etc.Now for some reason, I notice that squid isn't even started.To fix this, I wrote a start up script in /etc/rcS.d/ that runs:/etc/init.d/squid3 startAnd I notice it still isn't starting.So I write "/etc/init.d/squid3 start" and put it in my ip-up.d/ script.Everything in the script is being executed, but the squid server.I've tried reinstalling squid... what am I missing? where does the computer start these services?

At work we use autofs4, and we also take advangate of the -DOSNMAE=blah and -DOSREL=blah for our automount maps. We're moving some systems to autofs5 and I can't for the life of me figure out how to pass these options properly. There's no 'localoptions' in the init script anymore as there was for autofs4. I've tried adding the flags to the OPTIONS variable in /etc/default/autofs. That adds them to the global autofs process but then nothing in the automounter mounts.

Ubuntu 9.10 will not boot! System froze this morning, I restarted and it is now failing to boot. Starts loading grub and I get this message:
mount: mounting /dev/disk/by-uuid/04aa3697-7bc0-45b5-b86a-77a1e6534bd5 on /root failed: invalid argument
mount: mounting /sys on /root/sys failed: no such file or directory
mount: mounting /dev on /root/sys failed: no such file or directory
[code]....
I booted with 9.04 LiveCD discovered the drive could not be mounted-ran fsck -ln and it told me the drive has no valid partition table. I have had intermittent problems mounting flash drives before this, so I'm kind of worried it might be a hardware issue.Also have files on that drive I would rather not lose, so reinstalling is hopefully a last resort.

While I was using my computer a few days ago, the terminal stopped working properly, so I tried to reboot, and when it started up again it wouldn't boot and said "no init found. try passing init=bootarg"
This has happened twice before, so I really need to figure out what keeps happening, otherwise I can't continue to use linux. i reinstalled both times before. i think that this is caused by a process that prevents me from using the hard drive, because when I try to check the disk in the terminal or in gparted, it says Device or resource busy while trying to open /dev/sda1. Filesystem mounted or opened exclusively by another program?
Also, in the disk utility, in the lower right corner of the filesystem it has a spinning "loading wheel".(i'm not sure if that means anything)
I am using ubuntu 10.10, but am not sure what kernel I am using, but i tried a few different kernel options(there's three of them at start up). safe mode does not work either.

I've got an Ubuntu Server 10.10 with Bacula. Bacula is not using Upstart at boot time, it is started using legacy init.d scripts. MySQL on the other hand uses Upstart. This causes MySQL to start after Bacula, thus preventing Bacula director from connecting to the MySQL database - causing an error.I've tried to change the order of the init.d scripts in /etc/rc2.d, giving mysql the prefix S20 and bacula prefixes ranging from S90-S93, but to no avail. The bacula scripts are still loading before MySQL. how to configure the order of boot scripts when using both Upstart and legacy init.d scripts?

Im am building a Linux distro. It will be very tiny and fast.
I only have a minimal linuxkernel (bzImage) who is 1,2 mb big. And then I have Busybox who is 174,6 kb big.
The commands in busybox is: cd, ls, mkdir, rmdir, wget, httpd, clear, rm, poweroff, halt, reboot, fdisk, mount, umount, free, and cp.
When I compiled the kernel i use initramfs/initrd function and point it to a folder where initrd/initramfs source is.
The kernel works OK with others initramfs/initrd files. But not with my own.
Quote:
Here is how the end of the kernelcomplie look like.
Quote:
Here is my init file who is the initrd/initramfs source.
Quote:
The initramfs folder contains "bin" (folder) and "init" a file. No more.
The problem is that the kernel cannot find/read init file.

I'm trying to write a init.d script to daemonise a sagemath notebook server. Here's what I've done so far, I've copied /etc/init.d/single for the structure, and tried to use dtach to provide a handle to access the process. However, my main problem is issuing the signals to kill the process (Ctrl-C) from a bash script and exit dtach (Ctrl-`)

I just installed the netbook remix 10.10 on my laptop. I have been using Unity and I would much rather prefer a standard GNOME desktop. I know there was a way to change the netbook interface to a standard GNOME one on the 8.04 remix. Anyone know if there's a way to do it in 10.10?

I upgraded a working Ubuntu system that I'd previously configured to accept tcp connections for the X server, which it's magically gone and added back in again. I can't now figure out how to disable it.
I've edited /etc/gdm/gdm.schemas and changed DisallowTCP to false. I've edited /etc/X11/xinit/xserverrc and removed the nolisten tcp line, but it still comes up with it.
The System->Administration->Login Screen has no option for security (pretty sure that's how I fixed it last time).
