Programming :: Getting A INIT Script To Work?
Feb 23, 2011
This is my first init script, so far, it atleast starts the daemon but it fails at creating a pid, so later on I can use to, to either stop it or reload it. Here's the current code: Further more, the script returns ok that it started the pid, when in fact, the pid fails in the background, this script needs MUCH improvement, some help would be nice to fix this script. :/
Code:
#! /bin/sh
### BEGIN INIT INFO
# Provides: znc
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6

I have written an init script and placed it in /etc/init.d/ directory.What I would like to know is, will the script run automatically or we need to install the script using "install_initd" command.If I have to invoke this command manullay, what will be the best place to do this ? Can I add this to "/etc/init.d/rcS" file

I just installed my machine with ubuntu 9.04. When I run "init 3" or "telinit 3", nothing happens. I need to exit the X server to install a video driver.

I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail.
The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

What a nuisance after upgrading from Fedora 12 to Fedora 13 the terminal initialisation and the running of agetty agetty doesn't work any more. Same for printer configurations. Apparently this should now be done in /etc/sysconfig/init but where is the documentation? how to use the new /etc/sysconfig/init to do what the event.d scripts used to do.

I'm running XBMC media center which is built on Ubuntu and I'm trying to mount a network share, but I can't seem to automate it. If I manually run:
Code:
mount -t cifs -o file_mode=0777,dir_mode=0777 //192.168.1.20/disk7/xbmc_thumbs/Thumbnails /home/kevin/.xbmc/userdata/Thumbnails
The mount is created and everything works fine. But obviously the mount eill be lost on the next boot. A few months back, when I was running a previous version of XBMC and first instructed on how to do this, I was told to put that command in /etc/init.d/rc.local so the mount would automatically be created at boot. I did and it worked. The other day I upgraded to a new XBMC build (which is built on the newer Lucid Ubuntu) and while the same command creates the mount, putting it in /etc/init.d/rc.local does not create it on boot. Someone suggested the fstab was the better place to create the mount. So I inserted the following in /etc/fstab:
Code:
//192.168.1.20/disk7/XBMC_thumbs/Thumbnails /home/kevin/.xbmc/userdata/Thumbnails cifs file_mode=0777,dir_mode=0777 0 0
That doesn't work either. What am I doing wrong and how can I get this mount auto-created on boot?

Well, just as the title of this post says, I am having keyboard and mouse problems. Here's the storyMy friend Cody wanted me to take a look at his computer for him (I'm sort of known as a Linux nerd in my school lol) because his keyboard and mouse do not at all work in init 4 mode. I've tried reconfiguring the keyboard and mouse by trying a different module. I've even tried reconfiguring X alltogether by running "X -configure", which didn't work

I have an a script in /etc/rc.d/init.d script that I would like to start and stop my sample application. I have named my script "foo", then I can start running my application my typing $ foo start but this does not return [OK] like other scripts do and does not return to shell prompt. My application is basically like this
int main()
{
do {
printf("Hi
");
sleep(1);
} while (1);
}
What is missing from my application that prevents from returning the shell prompt?

I have an initscript that behaves slightly differently in the UK than it does in the US. Not a huge issue, but I'd like to know why and how to fix it. I imagine it has something to do with localization, but I'm at a loss as to what it could be, as it's just bash.
in the UK:
Code:
[root@server ~]# /etc/init.d/worker
status}
in the US:

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 have a project in which many processes run. p1,p2,p3.
->There are some .so files are included in some process when needed example ppp.so in process p1 (when ppp is needed and will go like a plugin) but it has a init () function how a process includes a init() function ?
->process p1 has main function i.e main()
->so evry process has main() right ?
what is the difference between init () and main () functoins. where is init () used and how many init() a process van have ?

I'm running a Debian based Linux compiled for ARM9 hardware. I am trying to auto start a process on bootup but occasionally I find that my startup script becomes empty (i.e. the file still exists but has not data). The script is located in /etc/init.d/S91-sercom
Here's the script:
Code:
#!/bin/sh # /etc/init.d/S91-sercom
# Start the Serial Communication Protocol Program at boot
echo "Starting Serial Communication"

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:

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.

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.

Is there any difference in cpu usage for process in init.rc(runs automatic when boot is happened) and manually running process. Will these both have same priority by default...?

This code will execute fairly well, however, if you enter multiple values that are not A/a or b, 1 or 2, then when the program resets, cin does not behave normally. Instead of waiting for input, it acts as if it has already been given input, and the input is the next character from the one entered.For example, entering "345" and submitting it at the (cin >> a line will individually pass the values 3, 4, and 5 through the if/else and switch statements, rather than only inputting the first value, 3, or all the values, 345.
If you enter, for example, "3343634563456345", then it will pass through the do{}while(); loop 16 times, with each pass having a = to the next character value. The cin >> a; is performed, and this is verifiable in GDB, however it never asks for input from stdin, and instead gets its input from somewhere else. How can I observe that, and what is going on?Furthermore, if you enter "cdefghijklmnopqrstuvwxyzab", it will pass through 25 times, and stop at a, which goes through the switch, and ends at a case statement that does not adjust the false value of mreset, thereby allowing the program to end.

I have a script that will build a list of hosts and it works fine Code: for ((i=$START; i<=$END; i++)); do echo "$NAME$i"; done But I need it to build the START and END on different number formats (i.e. 1 -> 10, 01->10, 001 ->010)
I am trying to use the seq command but can't get it to work quite right with the -w flag in the following Code: for ((myseq=$START; myseq<=$END; myseq ++)) do echo "$NAME${myseq}" done I am fully aware that this syntax is probably wrong, and need to know how to correct it.

I understand that a website can set a cookie which means a little text file with a no. in it will be created on the client side, and then the no. will get sent to the server with every visit. But how is this used to customize a page? Does this mean that a MySQL database *has* to be created, which can be used to match up that no. with a particular login name, for instance? How exactly is this pulled off?
