Fedora :: Help Needed In Creating Configuration File
Jun 3, 2010
I'm a bit of a newbie with regards to Linux so please bear with me. Basically I've got a problem with frequent hard drive unloads (first diagnosed by hard disk clicking whilst idle)So I need to adjust my advanced power management settings using hdparm to fix the issue. Indeed, following the instructions I temporarily fixed the problem by issuing the command.Again should i create a blank text file using gnomesu gedit and name it disk in the above folder (and then copying the stuff given in the link)?

What are the bare minimum configuration files that would be needed to rebuild a RHEL server?We are thinking about creating a generic base image and then just copying over the necessary files (fstab, hosts, networking, etc) to get a failed system back up and running in the least amount of time possible. I am fairly new to Linux and have suggested that we have a share on a redundant server that is /server_configs/Svr_name/*.* (names are subject to change and *.* would be all of the pertinent config files to make a fresh build customized enough to emulate the failed server).Is this even possible and/or plausible?

I'm using Debian Jessie Cinnamon right now. I've got 1 user account on my machine--fred--as well as root, of course. "fred" is an administrator, and many times that is enough for root priviledges, for example, I can install packages via apt or dpkg. However, I cannot access "Users and Groups", or install packages via GDebi, with my password. For that, I have to have the root password.
I know that it is possible to let the admin account handle everything and not even need root--for example, Mint and (I believe) Ubuntu do it this way. I don't know how, though.
Code: Select allgroups fred
fred : fred cdrom floppy sudo audio dip video plugdev netdev lpadmin scanner bluetooth
I did disable the root account by Code: Select allsudo passwd -l root to see if it would make any change. Nothing different happened except that I now can't use GDebi or access "Users and Groups" since the root account and therefore password is inactivated. Not a big deal to get it back, though.

I am trying to create a bootable DVD disk of Fedora. I am having trouble in doing this. I want to format the Hard drive and create a new file system. I have downloaded the source cds for fedora12 AND fedorai386 downloads. I have been trying to create a DVD burn with the Fedora12.iso extracted and then burned to DVD. This does not work. I just want to be able to pop the DVD in and then start the install, and on any machine.

I have downloaded Fedora-12-x86_64-DVD.iso. Now I want to create a bootable USB from the downloaded ISO file. I tried with the latest version of liveusb-creator 3.9.1. I am unable to do so. It took around 3 days to download the iso file and now I cant even use it.
ERROR MESSAGE::

I downloaded three iso-images, 1 dvd-image and 2 cd-images:
openSUSE-11.3-DVD-i586.iso
openSUSE-11.3-GNOME-LiveCD-i686.iso
openSUSE-11.3-KDE4-LiveCD-i686.iso
Being paranoid, I created iso-files from the burnt DVD-R and the two burnt CD-R to verify integrity.
The iso-file of the DVD-R was identical to the downloaded image. Both iso-files created from the CD-R were different in size.
The original size of openSUSE-11.3-KDE4-LiveCD-i686.iso is 719.323.136 Bytes.
I only got 718.938.112 Bytes when recreating an ISO-file from my CD-R.
The CD-R is from Sony. When the length of my ISO-file doesn't correspond to the downloaded one, the checksum file verification doesn't work.

I have a server running debian 5 in a closed intranet (I can't get to the intenet). I want to install some program and update others.
Is there a way to download part of a repository (using a FTP client) so I could burn it on a DVD?

I'd like to create my own custom Debian live CD — the idea being to have my own rescue CD with my favorite Debian tools installed. I read about bootcd and was going to give that a try, after creating the ideal system in a qemu virtual machine.
How much exactly can you install on a system so that bootcd can still fit it on a CD? I'm presuming there is some kind of compression involved. When I tried to create my VM, I coudln't get Jessie + LXDE to install onto a 2GB virtual drive (net install) so naturally I'm wondering what I'm going to be able to put on a 700MB CD.

error message when I ran my program that I couldn't open my local file. I have two files first one is called client, second one is called server I am using named pipes to sent a message from client to the other file called server in client I used mknod() to create the two named pipes,one for read,one for write and created new thread in client using fork() spawned a child process that executed the server file both named pipes are opened the client file got the message from the user and sent it through the named pipes to the server file when the server receives the message , it needs to verfify it is correct in the server file, a local file descriptor is created to read and send this verifing message when it is not correct but I am getting an OPEN() error when I tried to open this shared local array buff and attach it to a file descriptor where the message is kept why do I get this error in server file

Why would a linux web server need chmlib(s)? I am reading about installing drupal on slackware and I came across: [URL] Can anyone elaborate on this explainatioin: "chmlib is a library file needed to view Microsoft ITSS or CHM format files. You need to install chmlib first before installing xchm to view chm files in kde. Here is a guide on how to build chmlib for Slackware Linux and install the result package." Is this to make webpages more universal? Or are these libraries just to view some type of MS files in Kde? What type of files are these libraries for? I don't use kde. Sorry found the answer to my questions: "chm is Compiled HTML Help which is not a strange file format nowadays" The howto for KDE is here: [URL]

Having an issue with rsync
I launch the following
Code: Select allrsync -avz --remove-source-files --log-file=/home/pi/rsync.log --temp-dir
=/data/temp --partial --progress -e "ssh" 192.168.1.100://data/ext/downloads/File.ext /data/
Basically I download to main PC and rsync to my pi as the pi has a fraction of the speed for some reason when downloading form a source outside of my network.
The first few files will sync fine. Then I start getting errors like this
Code: Select allrsync: rename "/data/temp/.File.ext.y1716M" -> "File.ext": No such file or directory
(2)
The directory on the host has user and group ownership as pi. Rsync has been setup to login without a password.

I am very new to linux.I have a network camera which only has an Ethernet port but no WiFi. Sadly no Ethernet port is available close to the camera.
Therefore I now bought a raspberry pi and installed raspbian to create a bridge into the wireless network, for connecting the camera to the internet.I now played around with the interface- and bridge configuration but I have problems with it.This is how my interfaces file looks like:
(The WiFi is secured with WPA2 Enterprise)
Code: Select all# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
[code]....
The WiFi is connection works fine and I am in the internet using the WiFi.But I am wondering about eth0. The network parameters I specified are not the same as the parameters ifconfig tells me.Ip, Broadcast, Mask, nothing is as specified.It would be nice to give the camera a static IP that I can access it always with the same IP from the RaspberryPi.The Raspberry Pi itself gets always a new IP from the WiFi network. How do I get the camera into the internet using the existing connection of the Pi?

I have a trayless SATA hotswap bay that is really terrific for quickly attaching and removing SATA hard drives. I'm trying to write a udev rule to create a symbolic link to the device node for the drive that is attached through the hotswap bay (/dev/bay -> /dev/sdX). This eliminates any ambiguity when performing destructive tasks (fdisk, etc). I'm running squeeze amd64. I've read through several tutorials and have it working somewhat. Here's the output of udevadm info for a drive attached via the hotswap bay.
looking at device '/devices/pci0000:00/0000:00:11.0/host7/target7:0:0/7:0:0:0/block/sdb':
KERNEL=="sdb"
SUBSYSTEM=="block"
DRIVER==""
ATTR{range}=="16"
ATTR{ext_range}=="256"
ATTR{removable}=="0"
ATTR{ro}=="0"
ATTR{size}=="156301488"
ATTR{alignment_offset}=="0"
ATTR{capability}=="52" ....
Here is my udev rule
DEVPATH=="/devices/pci0000:00/0000:00:11.0/host7/*", SUBSYSTEM=="block", SYMLINK+="bay%n"
This produces the desired behavior and gives me an fdisk-able device node. The problem I am having is that the "host" component of the DEVPATH varies from bootup to bootup. I'm just using on onboard SATA, host2-7, specifically host7. There is also onboard PATA, host0-1. It seems to just be random which "host"s are assigned to which controller. For example, the next time I boot the system, the onboard SATA will be host0-5 and the onboard PATA will be host6-7. In this simple case, I could just write 2 rules, one for each possibility and it would still be correct because of the different PCI addresses of the two controllers. But on systems with more SCSI (uh... libata, actually) controllers, a "host" file can point to different physical ports between bootstraps. This would be bad. Does anyone know of a way to write a rule to tie a device node to a specific physical SATA port on the motherboard/hba?

I'm using F14 (preupgrade has an unhandled exception) x86_64 version with Gnome desktop, and I think after some updates I'm unable to go directly between app toolbar to os toolbar and vice versa. For example, I can start opera fine. Once it's started, I'm not able to change tabs or basically do anything in opera, but I can still access the window tabs on the bottom (OS or buttons on top). I need to right click somewhere on the OS, and then go into opera to use mouse there.
Once I do that, then I can't access the OS buttons, (switch windows/screen on bottom, volume controls on top, open new apps) until I right click somewhere in opera. It seems like there's a right focus button that is stuck somewhere. I'm not sure which recent upgrade caused it (if it was an upgrade), as it was working fine for a long time before. Keyboard shortcuts are ok though. It seems to be a gnome problem, as when I logged into KDE desktop it is ok.

Recently made the switch from the evil OS, now running F14, KDE desktop. I use a Logitech Marble Mouse, which has no middle button but two scroll buttons, and have been trying to configure button mapping (I think this may also be called Xorg hotplugging?) to map one of the scroll buttons as a middle button. The most helpful info I have yet found was on https://wiki.archlinux.org/index.php...h_Marble_Mouse which seems to provide plenty of info on the subject--enough I should have no problem mapping the buttons the way I want. The only problem is I have no 10-evdev.conf file in my xorg.conf.d folder. I opened a console and ran ls as root for good measure, but the only file that showed up was 00-system-setup-keyboard.conf .

I just recently upgraded my computer from fedora 11 => 12.After moving /home to a separate partition the installation was very simpel.I only had to reconnect my windows system.BUT a strange problem has started to appear.
1) Booting to grub is no problem at all ( I have configured grub to be able to select windows if I want)
2) I always see the grub count down on my screen.
3) then there is a lot of discaccesses but the screen with the fedora symbol is not seen and then my monitor goes to sleep.
4) I usually(always) have to turn my computer off and try again at least three times before the screen with the fedora-sign is seen.
5) If the fedora-sign lights up I have no problem with login and use of the computer.
There seems to be a very unstable situation between grub and XwindowsHas anyone a solution or at least a explanation?

I'm taking a class this semester on Linux and a Fedora 13 DVD came with the book. Just now I've installed Fedora at home and started the updates. I saw a PAE entry in the updates so I went to the Terminal and typed uname -r and I see that the Fedora 13 DVD installed a PAE kernel on my machine that has only 1 GB of RAM.
Why did it do that?
Can I swap out the PAE kernel for a non-PAE kernel? (edit- I'm a Linux noob so I don't know)
Does it really matter?
After the updates I was going to try to install the proprietary Nvidia driver.

My installation went fine. Apache, PHP, and MYSQL all work independently. My trouble getting PHP to serve MySQL content. The first thing I did was look in the PHP.INI file to check that it was set up correctly. Then I discovered my install of PHP does not have the expected directives, namely extension_dir or any DLL comments where I can enable MYSQL. Instead my config file has a PHP.D directory. In that directory there are no files for MYSQL. I look at the PHP.net site and I can't find any info on how to write this file. And there's the issue of the missing extension_dir directive.
As I said, I visited the PHP.net site and could not find any specific manual pages explaining this change to PHP 5.2.11. I downloaded "the latest php.ini" development file from the site. As near as I can tell its for PHP 6.0.0 and it does have the extension_dir directive, and it still uses the DLLs in Dynamic Extensions section. (EDITED= The introduction of the PHP.INI file doesn't give a version number, however later under error handling there is a note: "as of PHP 6.0.0"). Why I can't find more information about this on any forum or at PHP.net?
