Programming :: Have Several Scripts In /etc/rcS.d/ Directory Which Are Required To Run On Start Up
Sep 20, 2010
I have several scripts in /etc/rcS.d/ directory which are required to run on start up.Now I have written a new script, and I want it to be run during the system start up itself (Not in any runlevel). SoI have given the default start as,# Default Start :SBut when I use the command : "update-rc.d test_script.sh defaults".....it is creating symbolic links to/etc/rc0.d /etc/rc1.d ..../etc/rc6.d.But I actually need a symbolic link in the /etc/rcS.d/ directory.Is there is any way to achieve this ( I tried manullay creating a link in /etc/rcS.d, but that is not running the script on system start up).

I'm setting up a Python-based webserver on my Debian box. Setup: The Debian OS is VM based, but I've switched the VirtualBox from NAT to Bridged. IP of the VM setup = 192.168.1.7 (per my router's admin screen or ifconfig). I've succesfully set up my router's port forwarding for both ssh and HTTP. I've successfully set up my router's dynamic dns using [URL].
Regardless of the specific Python webserver I'm using (Django, CherryPy, standard library), I have to start the webserver @ 192.168.1.7:80 using sudo. Otherwise I get an error about not having permission to access the port. None of the webserver tutorials mention needing to use sudo when specifying an ip:port.
Question: why do I need to use sudo to start these webservers? Is it an indication that I shouldn't be using 192.168.1.7? Or that I'm not setting a config file properly somewhere?

As part of a package manager I am trying to build I am at the stage of checking if my system has the latest packages installed. To this end I would like some feedback on pieces that could be improved or perhaps alternatives that I can utilise. To the aficionados' of Perl, Python and the like, whilst I know these may be better suited to the task, the package manager is currently completely bash so I am trying to stay within this paradigm for the moment. I have edited this version slightly as it normally would tie in with the rest of my scripts which are not shown here. If there are any questions please ask and I will answer to the best of my ability:

it's been a long time since I did coding in C, but thought to pick up a very old project again, just to show off what I have been working on ten years ago.I deducted my problem as follows:
Code:
#include <stdio.h>
#include <stdlib.h>
#define bit1 1
#define bit2 2
[Code]...
Why is it saying that bar->act is not a valid lvalue while both bar->act and the bit are cast to (long long)?

I have written a script to run commands on remote servers, it is working fine. But when I am running "sudo commands" on the remote servers, it asks for me password after prompting for ssh password. I am unable to automate this password prompt (which is just after ssh password prompt). This is the function I am using to provide passwords
Code:
pass ()
{
cd $DIR/"$dt1"_"$dt"
/usr/bin/perl << 'EOF'
use strict;
[code]....
I want the same function to be used , when it expects for sudo passwords for any of the below lines:
Code:
[sudo] password for vikas: orPassword: This is my "cmd" file passed in pass () function.
Code:
ssh -t -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no 192.168.1.100 "bash rcmds"
This is my script output
Quote:
[vikas@box1 ~]$ ./rscript.sh
++ rm -rf /home/vikas/May_31
++ mkdir -p /home/vikas/May_31
++ set +x
[code]....
how to automate the password prompt required for sudo commands.

I've recently starting dabbling with python and gtk/cairo bindings. Can anyone point me to a quick and easy way to convert a colour value from hex (e.g. #FF8000) into the format required by the set_source_rgb function?E.g. I have this:
Code:
cr=area.window.cairo_create()
cr.set_source_rgba(0.5,0.5,0,0.8)

I am having troubles starting superPI benchmark test on Linux. I have it in a file named 'super pi' so ./super_pi doesn't work. I can't figure it out how to do it. In cmd(Win) I would do it like this
cd C:/super pi/
super_pi
If the file would be located in C:/super pi/ The problem is I somehow can't tell the path to the file.

For any custom application I create which needs to run at startup, what I normally do is have an entry in my /etc/init.local that executes the app.Now if I just putCode:/data/app/prod/start And the app writes data to relative paths, it will be writing data all over the system. Is there a method of starting a script so it is aware of the folder it is in? Sure I can do "cd [folder]" then start the app, but wondering if there's a better way.

I type in /etc/init.d/hostname.sh start
And I receive bash: /etc/init.d/hostname.sh: No such file directory
For hostname I've use "hostname" and my actual hostname, and both receive the same error.
Although when I do hostname is shows the correct hostname but without the the comcast part of it , and when I type in hostname -f, I get the correct hostname with the comcast part of it.

I messed up the whole thing and the settings. Created some new thing named rhk which I can't remember as it got all messed up and Now I am getting nothing after Linux Mint 10(julia) boots up - no start menu, no panel, no taskbar nothing. I tried to work in the recovery mode and got some(downloaded) 216mb of something(in the repair broken packages). Moreover whenver I have booted in it shows messages like Could not update ICEauthority file /home/rk./.ICEauthority
there is a problem with the configuration server. (usr/lib/libconfig24/gconfsanitycheck2 exited with status 256) The panel encountered a problem while loading "OAFIID: NOME_mintMenu" The panel encountered a problem while loading "OAFIID: GNOME_IndicatorApplet" Naulitis could not create the following reqiured folders: /home/rk/Desktop, /home/rk/. Naulitis Moreover Alt+F2 gives Run application or run with file and nothing seems to be working.

I urgently need expert assistance. During a cold-start reboot, something corrupted my / directory making it impossible to access much of anything. I was able to log into a recovery console and do "ls /" which shows most of the critical directories although "media" is missing. However attempting to "ls /home" gets the "no such file or directory" error message, as do attempts to ls most of the others. Doing "ls -l /" gets one item listed, followed by a single record out of /var/log/syslog, then nothing at all.
Attempting a normal login (I've disabled the quiet and splash options, so I see all the startup messages) gets to doing fsck on the swap partition, and that stalls out at 14% complete. The fsck on the root partition completed okay, apparently. This machine is my router, firewall, FTP server, and also hosts VirtualBox VMs that contain all of my customer support tools. The VMs themselves are partially backed up on another box, fortunately, but it took me a couple of months to get the failed box configured properly so if possible I need to recover it. For lack of space, I've never been able to do a full backup of it -- and permissions have foiled portions of all my other backup attempts on it.
Complicating matters is the fact that I have a moderately large data recovery job scheduled to arrive this evening (July 3) to be done while the customer's business is shut down for the holiday. Without the FTP server I'm unable to receive the files, which will total from 100 to 200 MB in all. Is it likely that testdisk may be able to rebuild the borked main root directory, if run from a live CD? The system is Hardy LTS 8.04.4, with 3 GB of RAM and a 250 GB SATA drive. I'm posting this from my WinXP laptop, which doesn't get along with my LAN so connects from a different router than the one that's down.

I’m new to C programming so I wrote the following program to see if everything I needed to write programs with GCC and the standard C library was already installed. I am having issues in OS 10.10.5, where I am unable to build and compile some simple code, either using Xcode or Sublime text. I decided to install Linux Mint in Virtual Box to see if it would work.
Code: Select all#include <stdio.h>
void main()
{
printf("Hello! This is my first C program with Linux Mint
");
}
For some reason, I'm getting the following error:
mint@mint-VirtualBox ~/Desktop $ gcc hello.c -o hello1
hello.c:2:19: fatal error: stdio.h: No such file or directory
#include <stdio.h>
