Ubuntu Installation :: Understanding Legacy GRUB 'chainloader'
Jun 8, 2010The O'Reilly book, Linux in a Nutshell, Sixth Edition has this excerpted section (on Legacy GRUB):If GRUB is installed in the MBR, you can chainload Windows by setting the root device to the partition that has the Windows boot loader, making it the active partition, and then using the chainloader command to read the Windows boot sector.If GRUB has been installed to (hd0,0)'s MBR, then I am confused what "file" chainloader +1 is pointing to. Obviously, it is not the MBR but that is confusing to me. When one boots a Linux system with GRUB in the MBR, what file does chainloader +1 point to?
View 2 Replies View RelatedGeneral :: DD Imaging Of Builds Better Understanding
Nov 12, 2010I am learning how to use DD for creating images across networks and locally but needed some clarification.
1 - When creating an image, I noticed that there is no verbose to show you the progress, How can I accomplish this?
2 - When I run this on a 8G usbstick it takes a long time to image. How can I speed up this process?
PHP Code:
dd if=/dev/sdb of=/home/test/images/image.dd
3 - When an image is restored like
PHP Code:
dd if=/home/test/images/image.dd of=/dev/sdb
will that give me a working bootable usbstick? For example if I imaged a working usbstick with Ubuntu on it using DD and restored it like the example above on a different usbstick, will this give me a booting new usbstick? I hope that came across ok?
General :: Understanding How Pipe Works In Bash
Aug 21, 2010I don't quite understand how pipes work in bash. I know that it takes an output from one command as the input in another command. What an output is I can get because it's what the command prints out to the screen. But how do I know what input a command will take? Here is an example I thought would work:
Which gem | rm
Unfortunately it didn't.
Which gem prints out "/usr/bin/gem" so that must be the output right? I thought that was given to rm so it would be "rm /usr/bin/gem" but I was wrong. How do I know what input a command takes?
General :: Finding An Appropriate Distro And Understanding Setup?
Aug 11, 2010I'm trying to set up a machine to "drive" a piece of equipment (a metal plate embosser [kind of like a daisywheel printer for credit card sized pieces of metal], FWIW). What I ideally want is a linux distro that I can boot from CD (I think the term is Live CD?), log itself in as a user and display only a console. It needs to be able to support windows fileshares and python.
Essentially it needs to boot, connect to a single fileshare on a Win2k8 machine, and be able to execute a couple of scripts that will output to a serial port. One of them will be more or less the following:
wget http://WEBSITE/?<parameter passed to script> --quiet --output-document=<name of serial port>
The other is a somewhat more complicated Python script that processes a CSV spreadsheet and produces data for the machine.

View 1 Replies View RelatedGeneral :: Understanding Ubuntu User / Group Permissions
May 20, 2010I'm beginning to deal with more than one user on my system (it's a VPS serving some sites) and I need to make sure I understand how group permissions work. I have an account named "admin" .. it's basically the primary account that is used for serving most of the sites that I control myself. Now, I added a second account named "Ville" as one of my users wants to be able to administer that site. So, I can do this the easy way and just chown their domains folder under the ville user, they have permission to do whatever they need be and so forth. However, let's say I want to also give the admin user access to the files (modifying and all) .. how can I put both users into the same group and give them both permission?
I've tried doing:
sudo usermod -a -G admin ville
To add the ville into the admin group, but ville still cannot edit files by admin. Permissions for the primary directory for the ville user are read/write for both owner and group, and the current group for the files is admin:admin ..
But ville still can't write into the directory. So, what should I be doing here to get this right and secure at the same time?

General :: Lack Basic Understanding Of Permissions (Apache)
Apr 8, 2010I am very new to linux. The first time i ran a linux machine was one Saturday. Anyway I am trying to set up an apache web server, all I want to do is play around with html and post it on my unbuntu server so it is available to the internet. I am also trying to install samba but I am having trouble with that so for now I am using winscp. Ok, so I made a folder in my home directory for webstuff, and set up apache to look in that folder.
mkdir /home/username/webstuff
I put my index.html file into the /webstuff folder.
But when I go to my website, it says 403 error unable to access "/"
Did I make the folder in the right place? I do not want people being able to access my / folder so maby I made the web stuff folder in the wrong place? Also I thought I would just put my inded.html file inside of the default one apache gives you, but when I tried to transfer index.html it said permission denied. How to set up permissions so I can use apache and transfer my html files from my remote desktop to my server would be great!
General :: Understanding Idle/Inactive Sessions And Whether Or Not Someone Is Logged In?
Jan 5, 2011I'm trying to understand if anyone is left on a server. Basically I manage a simple linux server remotely used by 3-4 individuals. I can never tell if someone is actually on or not using w/who.What I'm seeing is some people having what appears to be inactive/lost VNC sessions. I don't understand idle fully, but I do believe a program (without user interaction) can clear idle back to 0, correct?Anyway, I'm asking because every now and then I need to reboot the server, and I do not want to interrupt any program working on calculations or waiting on having the data saved.

Aug 5, 2010Can't find info on how to move my hundreds of Camino bookmarks from a Mac G5 power-pc OSx Leopard to Ubuntu setup onto an older AMD PC. Camino doesn't appear to have a Linux version at least that I can find. If it does have one I would prefer Camino. Probably not so is it preferable in any way discernable, to the Firefox that I'm using now (doesn't look like it to me)?
Secondly, the vertical arrows for paging up and down on the screen - can't seem to find the preference that puts them together at the bottom instead of up arrow at the top and down arrow at the bottom.

View 1 Replies View RelatedUbuntu :: Placement Of /home On External Drive Causes Natty Narwhal To Not Boot Past Plymouth
Nov 27, 2010I recently reinstalled Ubuntu 11.04 "Natty Narwhal" Daily 20101124 on my netbook and decided to place /home on an external 500GB SimpleTech hard drive because the netbook's internal SSD is only 8 GB.
Well, when I boot into the main SSD to try and test out the system, I have two problems:
First of all, GRUB is unstable and won't always find the kernel to boot. In particular, I have to hit <Enter> one, two, even three times just for GRUB to find the kernel and boot the system.
However, that's not all:
When the system is booting, I wait endlessly for X to start. It doesn't. The Plymouth splash screen stays there and it looks like the system is endlessly booting with no progress.
Suggest chrooting into the drive and doing a "sudo apt-get dist-upgrade" by any chance? This being in order to make the system on the drive up-to-date? If so, I will see if it boots.
