General :: Programs Run At Boot Time: Where Are They Hidden
Apr 15, 2011
I am struggling to understand where PackageKit is launched from at boot time (fedora FC13), and I'm starting to suspect that - since my previous experiences with much older Linux distros - in modern systems daemons/services/programs are launched at boot time from many other different points. In my case, I can't find an origin point for this program in /etc/rc5.d Where can I find a list of places to look into?

I am thinking of installing Ubuntu on my machine, and I may need to still keep windows 7 around for certain games/apps. I want to do a full disk encryption using Truecrypt. As I understand, Truecrypt is compatible with both linux/windows/OSX, and has an option for a "hidden operating system."I want to Install both win7 and ubuntu, with ubuntu as a hidden OS. I have watched tutorials on ..... showing the method for creating a hidden OS for Windows, in this tutorial the second volume was created from the first volume and was effectively a clone of the original OS. Basically what I am asking is---- Is it possible for a hidden volume with a bootable version of Ubuntu Linux to cohabitate on the same drive as windows?If so, are there any howto's/tutorials you could point me to?

[URL] I'm currently running simplyMEPIS 8.0.15 (rel 32). It's booting automatically off a USB. The way I have it configured right now, it just loads right up without a root menu or boot-options, just basically going straight to "hey, u ROOT or DEMO?" I'm not sure if there's a way to get back to the bash and load directly to RAM at this point.
In another thread I was looking into burning backups from k3b as I run live because my DVD-player isn't behaving right now under windows... 'still working on that I want to get a backup done before I do a hard install. It's my goal to get either Kismet, wireshark, or Airsnort/crack/peek running on this machine so I can start gathering packets and doing analysis. Is that a way that (atleast for the timebeing until I can work out backups) that I can install any of these programs directly to the USB (by editing the ISO somehow?), so that they'll be available when I liveboot?

just a general weirdness, but some folders that are in my /home folder don't show up. if i check "show hidden folders", they still don't show up. for all terms and purposes, they are simply not there. however, if i search for them through the search tool, or beagle, they show up as being in my /home folder. so, anyone have any idea how this happened, or how i can remedy this?

Does anyone know of a good time keeping/recording program for Ubuntu that I can use to log hours spent on a project for billing purposes? I'm getting back to doing some web work to make some extra cash, and would love to have a program that does this.

I was wondering if there is any tool or program that stores a copy of frequently used files eg. Binarys, program library's etc. in memory so when they are requested by the OS they load instantly. I'm asking because I have a system with plenty of ram but very slow hard disks. Having programs like opera and java/eclipse load from ram would greatly speed up their start time. Ideally they would be loaded into ram in the background after I log in. Of course all writes made to these files would have to be made to the files on disk for obvious reasons.I don't want the entire OS in ram because it will not fit, just frequently accessed files.

I don't know if it is just me but it seems like Ubuntu takes a long time to start up programs. For example, it takes me 10 seconds to start up "Ubuntu software center". My computer is a relatively fast one. It has 4 gb of ram and an intel core duo processor. I didn't install that many programs. Does anyone know what might be the source of the problem and how to fix it?

I suspect this has been posted before, but I'm new enough to the OS to lack the proper vocab for a proper search.
In any case, I'm basically trying to run programs remotely at work (from home) that will run for a long time. I first ssh into the appropriate network, then ssh into the individual machine. This works great and I can run programs no problem. The issue is that these programs can run for days or weeks, and the network kicks me out after some period of time due to inactivity.
Is there a way to start a program on a remote machine then terminate the connection but have it keep running?

When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.

I had bad experience with disk checking in windows. Boot checker just moved all more and more of my files to a hidden folder without me knowing. I lost a lot of photos due to this. Afterwards when I checked that folder I found that most of the files were intact and I was able to open them without a problem. How dumb is that a program moves files without your permition to do so So I'm wondering what happens with files on Ubuntu if they get corrupted or are suspected as corrupted? And how can I know if the automatic checking procedure that runs when booting found any corrupted files, bad sectors etc... ?

I installed Ubuntu netbook remix 9.10 and it ran fine. However, the boot menu is hidden and by default it always boots into Ubuntu (I don't know.. maybe the timeout was 0). I wanted to switch to a different kernel so I compiled a new kernel and installed it. But upon reboot it would always boot into the old kernel. So I updated grub and made the new kernel the default.
Now the new kernel is givine me a kernel panic and I can't access my system because the grub boot menu doesn't show anything (just boots into the newly compiled kernel and gives me a panic message). I don't have a recovery cd/usb. Is there a way for me to somehow slow grub down or show a menu? Pressing esc at boot doesn't help.

I just got a new acer laptop that came loaded with Win 7, and I want to dual boot with Ubuntu. Naturally the laptop didn't come with a Win 7 disc, but instead has the stupid recovery partition. I've made the recovery DVDs from the eRecovery program but....
From what I read the acer recovery setup is extremely picky and will refuse to work after the partitions have been messed with. Apparently the ALT+F10 to start the recovery process on boot won't even work if acer's MBR is overwritten. What's worse, even the recovery DVDs won't work without the MBR! (At least from what I've been reading... I guess if you install a different HD you are SOL) So how does one get around this? I couldn't care less about acer's stupid recovery partition, but if I ever need to send the computer in for service I think they actually charge extra to restore their crap.

I have installed Ubuntu 10 alongside with Windows XP. Consequently I need to make a choice at boot time. However, I feel that the system is not waiting very long, maybe 5 seconds or so, before going automatically into Ubuntu. Can that time be increased? If so, where or how?

I have a home build computer that has data corruption problems at boot time. I have exhausted all the troubleshooting steps that I know to try. Do you have any additional troubleshooting techniques that I should try?
Symptoms: I run both linux(ubuntu, mint and fedora) and win7 on this machine.Sometimes I have just one installed.Other times both in a dual boot setup. The OS installs just fine.The system runs just fine for a while.Then it fails to boot.At first I can fix the boot problems with grub or bootrec (/RebuildBcd, /FixMbr or /FixBoot) as indicated by the error messages.Eventually the system fails to boot at all and I have to wipe the disk(s) and reinstall the operating system.The linux installs seem to last a bit longer. I typically have linux running for a month before the troubles start, but I have to repave and rebuild within 3 months. The windows installs last at most 2 weeks before troubles develop. The system is turned on for the day or evening then turned off overnight.Once the system has booted all checks that I have run pass. On windows fciv.exe, sfc.exe have never deteced and troubles. On linux tripwire shows everything unchanged. Chkdsk and fsck have never reported errors.
Hardware:ASUS M3A78-EM motherboard. 2x2GB kingston memory from the ASUS QVL for this motherboard.I have used two hard disks in this system.WD caviar black 640G (WDC WD6401AALS-00L3B2).Seagate barracuda 7200.7 (ST3120026A).On some rebuilds I have used just one of the drives, sometimes I have both installed.The DVD burner is a LG 4x (HL-DT-ST DVD-RAM GH22NS30 ).The power supply was originally an el-cheapo Allied unit that came with the case.That has since been replaced with a Seasonic X650.And that is all that is in this system. I use the onboard video, sound and network. I have never plugged an external device into the system (not even a USB flash drive!).
Trouble shooting so far...I have run the memtest utility from both the ubuntu CD and the windows DVD many times. Even when run for several day neither test utility has ever found a memory error.I have run the seagate and western digital provided test and diagnostic tools on both of the hard disks. I have done this on both the unstable ASUS M3A778-EM system and a very stable gateway system.I have swapped out the HDD cables several times.I have replaced the cables with new cables and with cables pulled from a stable system.Because the corruption happens only at boot time I suspected the power supply was having problems under the extra load of disk spinup.So, I replaced the power supply. No success.
I have run the system with every version of the MB BIOS from the version that it shipped with to the latest and greatest. The BIOS upgrades made no noticeable difference.I have enabled and disabled automatic updates on both win7 and ubuntu linux. That made no noticeable difference.That is it. That is all the troubleshooting ideas I have had.

I am using Arch Linux and want to disable console messages which are displayed when the kernel boots. I have tried the quiet and loglevel=2 options in /boot/grub/menu.1st as given below:
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/c6dbfcdc-fcd8-498e-9182-f3bddc4f05ff ro loglevel=2
However I am still seeing console messages at boot. I used grub-install after the changes.
Any ideas where I am going wrong?

My Linux system was last rebooted few hours ago. But it seems little confusing for me to figure out the exact reason behind it. I guess following command should justify what i meant to say.
Code:
# date
Wed May 11 13:22:49 IST 2011
# last | grep "May 10"
reboot system boot 2.6.18-194.el5 Tue May 10 17:35 (19:46)
root pts/1 XXXX Tue May 10 17:24 - 18:18 (00:53)
[Code]...
My question is Why the uptime is saying that the system is up since last 47 min.It should be more than 1 day if i m not wrong.

I'd really like to be able to examine all the information that flys off the top of my terminal when my system boots (off of fd0, the only way I've done it, so far): review of "similar threads" yields nothing; seemingly not a man pages item; have not found any how-to's that cover this; the daemons for logging are third-to-the-last before logon prompt (and still displayed, the ONLY reason I know THAT); seems like it should be a compile-time sw-switch settng (sub-optimal since I'm still not comfortable with compiling kernels); but I was hoping it's already being captured in some log file somewhere that I'm as yet unaware exists. I do realize that if I had a printing console, this would be unnecessary.

I am experimenting with LUKS+dm_crypt. My setup is something like this: a LVM VG made of multiple Physical Volumes (PV). That VG contains multiple LV (Logical Volumes), most of them encrypted via LUKS+dm_crypt (via cryptsetup).Editing "/etc/crypttab", the system will requiere a passphrase for each encrypted LV. But since all my encrypted LVs share the same passphrase, I would like to be prompted only ONCE, instead of twelve times (I have 12 encrypted LV).
I have thought about writing a script to include in initrd that ask for the password once, store the result somewhere volatile (ramdisk?), and provide that password for the rest of "/etc/crypttab" entries.But this seems complex and fragile.I wonder if there is something I am missing, or some other easier way.

I need to start an application (graphical) when the PC start, even before anybody login, and use/launch a specific user. Now only can do this manually; when gdm starts, switch to any text tty [ie. Ctrl + Alt + F1], then I login into the special user, start a X server, export the DISPLAY environment variable, and start the application.
With this steps:
Code:
$X :1 -verbose -nr -nolisten tcp &
# Maybe Metacity -> $ metacity
$export DISPLAY=:1
$JavaApp &
Now i need put this steps (script) in some place to launch the app automatically, and with and specific user [ie. manager].
How can I made it? Maybe in init.d? or an special xinitrc? And how can start the app with the specific user? And, if is possible, who can stop the app when the system going turn off? I have Debian 5.0 and a beginner knowledge of shell script.

you can refer to this ubuntu thread for context, but i'll sum up what i'm trying to do here to spare the reading. basically i want to be able to schedule a filesystem check with automatic repairs at the next boot time. but i'm not sure if this will try to automatically fix errors which is what i want to do. the reason i want to do this is because i experienced a power outage (the machine was not plugged into an UPS) and i want to make sure everything is ok.
