How To Network Boot (PXE) The Ubuntu LiveCD

Colored-1920x1200 [DesktopNexus.com]

With Ubuntu’s latest release out the door, we thought we’d celebrate by showing you how to make it centrally available on your network by using network boot (PXE).

Overview

We already showed you how to setup a PXE server in the “What Is Network Booting (PXE) and How Can You Use It?” guide, in this guide we will show you how to add the Ubuntu LiveCD to the boot options.

If you are not already using Ubuntu as your number one “go to” for troubleshooting, diagnostics and rescue procedures tool… it will probably replace all of the tools you are currently using. Also, once the machine has booted into the Ubuntu live session, it is possible to perform the OS setup like you normally would. The immediate up shut of using Ubuntu over the network, is that if your already using the CD version, you will never again be looking for the CDs you forgot in the CD drives.

Prerequisites

  • It is assumed that you have already setup the FOG server as explained in our “What Is Network Booting (PXE) and How Can You Use It?” guide.
  • All the prerequisites for the FOG setup guide apply here as well.
  • This procedure has been used to make Ubuntu 9.10 (Karmic Koala) up to and including 11.04 (Natty Narwhal) network bootable. It may work for other Ubuntu like distributions (like Linux Mint) but hasn’t been tested.
  • You will see me use VIM as the editor program, this is just because I’m used to it… you may use any other editor that you’d like.

How does it work?
In general the Ubuntu LiveCD boot process that we all know is like so:

  • You put a CD into the cdrom drive the BIOS knows how to use the cdrom enough to get the boot program on the cdrom (isolinux).
  • Isolinux is responsible for the menu options. Once you select a boot entry like “Start or install Ubuntu”, it calls the kernal + initrd (initial ram disk) files, copies them into memory and passes parameters to them.
  • The now in RAM and in control kernel + initrd start the boot process, while using the parameters that where passed to them to determine things like: should the splash screen be shown? should the output be verbose?.
  • When the inirtrd scripts have finished loading drivers and device information, they look for the Ubuntu liveCD files to continue the boot process. The normal behavior is to look in the local physical cdrom drive.

For network boot:

  • Instead of a local media such as a CD, the client is booted using it’s network card (PXE) and is supplied with PXElinux over TFTP.
  • Just like Isolinux, PXElinux is responsible for the menu options. Once you select a boot entry, it calls the Ubuntu kernal + initrd files, copies them into memory and passes parameters to them.
  • The now in RAM and in control kernel +  initrd start the boot process, with our additional information that they should not be looking for the boot files in the client’s local physical cdrom drive, but rather in an NFS share on our FOG server.

This is possible because the Ubuntu creators have enabled networking by integrating, network cards drivers and protocols into the kernel + initrd files. For such an act, we can only say thank you to the Ubuntu team. Smile

Make the Ubuntu files available on the server

The first step is to make the Ubuntu files available on the server. You may opt to simply copy them from the CD drive, or extract them from the ISO, and that will work just fine. With that said, we will make the ISO auto-mounted. While not a must, doing this will enable you to use our “How to Upgrade your Ubuntu ISO Without Re-downloading” guide, to upgrade the Ubuntu version of your network boot without going through all the procedures from scratch or alternatively, replace a single file to update the entire entry.

With the above said, This author likes keeping a couple of past versions around, until the new one has been proven absolutely stable and issues free. That is why we will make a sub-directory and mount point according to version, but know that you could bypass that to have your single point of update.

  1. Copy the ISO into the “/tftpboot/howtogeek/linux” directory
  2. Create the mount point:

    sudo mkdir -p /tftpboot/howtogeek/linux/ubuntu/<version-of-ubuntu>

  3. Edit the “fstab” file to have the ISO auto-mounted at boot:

    sudo vim /etc/fstab

  4. Append to “fstab” the ISO mount entry:

    /tftpboot/howtogeek/linux/ubuntu-11.04-desktop-amd64.iso /tftpboot/howtogeek/linux/ubuntu/11.04 udf,iso9660 user,loop 0 0

    Note: Despite representation, this is one unbroken line.

  5. Test that the mount point works by issuing:

    sudo mount -a

  6. If all went well, you should be able to list the contents of the ISO by issuing:

    ls -lash /tftpboot/howtogeek/linux/ubuntu/11.04/

Create an NFS share

While the boot procedure starts by using PXE, the actual heavy lifting is done by the NFS share on the server. As we are basing this guide on our FOG server, the NFS components and some configurations have already been done for us by the FOG team, and all we have to do is add to them our Ubuntu share.

  1. Edit the “exports” file to add the new share:

    sudo vim /etc/exports

  2. Append to it the pointer to our ISO mount point:

    /tftpboot/howtogeek/linux/ubuntu/11.04/ *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)

  3. Restart the NFS service for the settings to take affect:

    sudo /etc/init.d/nfs-kernel-server restart

PXE menu setup

Edit the “Linux stuff” menu:

sudo vim /tftpboot/howtogeek/menus/linux.cfg

Append to it the following:

LABEL Ubuntu Livecd 11.04
MENU DEFAULT
KERNEL howtogeek/linux/ubuntu/11.04/casper/vmlinuz
APPEND root=/dev/nfs boot=casper netboot=nfs nfsroot=<YOUR-SERVER-IP>:/tftpboot/howtogeek/linux/ubuntu/11.04 initrd=howtogeek/linux/ubuntu/11.04/casper/initrd.lz quiet splash --

 

The above may look messy at first glance but all you have to do is replace *<YOUR-SERVER-IP> with the IP of your server NFS/PXE server.

For a clearer geek understanding, the text above will:

  • Create a new PXE entry in the“Linux” sub-menu called “Ubuntu 11.04”.
  • Because of the “MENU DEFAULT” parameter, this entry will be automatically selected when entering the “Linux” sub-menu.
  • Point the client to take the kernel + initrd files usinf TFTP from the relative path in the “/tftproot” directory of “howtogeek/linux/ubuntu…”
  • Point the initrd scripts to mount the “root” filesystem from the NFS share on the absolute path of “<YOUR-SERVER-IP>:/tftpboot/howtogeek…”

Note: I have tried (and failed) to use a DNS name instead of an IP for the “<YOUR-SERVER-IP>”, I’m guessing that at that stage of the boot process there simply still isn’t support for DNS… success stories are welcomed.

Possible procedures

You should now be able to boot a client into Ubuntu from PXE (Usually F12).

At this stage we suggest you take the time to review some of the things you can do with this outstanding tool:

One last thing, If you create your Ubuntu ISO, using this online builder, you will be able to slipstream all of the articles above into your PXE bootable Ubuntu.


Ubuntu is everything, all that once was and all that will be, Ubuntu controls time and space, Love and Death, Ubuntu can see into your mind, Ubuntu can see into your SOUL!!

    Nice one – worked like a dream!

    I used your recent how-to (http://www.howtogeek.com/57601/what-is-network-booting-pxe-and-how-can-you-use-it/) and then followed it up with the above instructions and bingo!

    Got a full Ubuntu 11.04 live boot on a PC which doesn’t even have an hard drive in it!
    It’s not even a new/decent PC – 2gig Ath CPU, 2 GIG memory, 100 network… Fantastic!

    Any chance of a guide to go with this one on how to make boot images (PLEASE!!!)?

  2. Aviad

    @FrankX

    i’m glad you’ve been able to successfully follow the guide, and i welcome you to the exciting world of PXEing :)
    by “boot images” do you mean the FOG image deployment mechanism?

    if so, i suggest you have a read through on their wiki… i’m not planning on making a guide for that in the near future.

  3. Larry Thiel

    I’ve been trying to build a PXE or gPXE server for some time. Your guide and FOG have made the last attempt the best one. Thank you. However, my needs differ a little as I am building it to use in different environments and mostly for use at a Linux Installfest. The biggest distinction is that I must serve a multitude of distros (e.g. ubuntu, Mint, Centos, etc) and versions per distro (32/64 bit, Gnome/KDE/LXCE/etc.). This means a few things:

    1. It would be best to put the .ISOs and menus etc in some home partition so they don’t have to be wiped on a system upgrade/clean install. If necessary, maybe they could be put there and linked from the location(s) you are using?
    2. Can the variations on s single distro have their .ISOs all in the same directory?
    3. It is not totally clear whether this method would result in all .ISOs being mounted, or if they only automount when needed. Also, is there a limit on the number that can BE automounted?

    You say you keep several versions of ubuntu but only show doing one. Are you planning to do a third article in this series?

    Thanks again!

  4. Aviad

    @Larry Thiel

    i’m glad to hear of yet another success story :)
    while i am planning on a third, fourth and beyond articles in this series, they are not currently planned to go deeper into the Ubuntu liveCD.

    so i’ll try to answer your questions in order:
    1. you can put the ISOs where ever you want, as long as you make the content available to the NFS share. as in all things Linux, there are no limits on how you can achieve that.

    2. sure… as long as they have different file names, there is no limitation on how many distros you can have in the directory or on the PXE server.

    3. this guide shows only how to mount the single ISO file and create a single PXE entry, to add additional distros (ISOs) simply rinse and repeat as necessary. as far as i know there is no limit on how many mounts you can do and every mount entry in “fstab” will be auto mounted either at boot or by issuing “mount -a”.
    if you would like to temporarily mount an ISO and not have it remain perminent, you can use our earlyer guide here.

    on our company’s production FOG server, we have no less then:

    Ubuntu:
    o 9.10×32
    o 9.10×64
    o 10.04×32
    o 10.04×64
    o 10.10×32
    o 10.10×64
    Debian:
    o Lenny installer x32
    o Lenny installer x64
    Fedora:
    o 15×64 installer

    and thats just off the top of my head… hope that answered your questions :)

  5. Larry Thiel

    Thank you Aviad,

    You said in your reply to me “if you would like to temporarily mount an ISO and not have it remain perminent, you can use our earlyer guide here.” as if you were going to link to one of your articles or name one, but did not do so. I would like to do this, preferably automatically when a PXE booter requests a particular distro, but even manually if I must.

    I don’t know how many I will end up doing so it MAY not be an issue. I just prefer to think ahead rather than having to restructure everything later.

  6. Larry Thiel

    In the article you said:

    Note: I have tried (and failed) to use a DNS name instead of an IP for the “”, I’m guessing that at that stage of the boot process there simply still isn’t support for DNS… success stories are welcomed.

    I have been told by others there is no support for this in any of the xxx.c32 menu systems. By the time any of those are ever used, the server is fully up and should know it’s own IP. My thought is to add some processing to (or following) the network startup script to copy unchanged menu files to the right names and use sed to replace the requisite text in the various menus for the PXE server. I think that could work. You could not do it to the real files because on the second network start they would not contain the original text to replace. Just a thought …

  7. Aviad

    the link was in the word here, but here it is again.
    http://www.howtogeek.com/howto/ubuntu/how-to-use-an-iso-image-on-ubuntu-linux/

    the DNS remark was referring to the fact that i had to change the FOG server’s IP once or twice since initial setup. because the PXE menus are using a “hard coded” address, it meant that i had to go back to the menus and change the IP (which at first i forgot). using a DNS name, would have absolved me from having to do this, but that it is not possible… makes sense?

  8. Larry Thiel

    Thanks for the link. You are correct; it WAS in the word “here” though it did not look like a link until I moused over it. My bad!

    I should tell you I have made a royal shambles of this trying to extend it as I was talking about. I had your single .ISO working to net boot, but I wanted more. I tried placing the .ISOs in my home directory tree and mounting 6 of them to 6 directories under /mnt. I changed all the menus and fstab and exports appropriately an now nothing works except the single menu referencing them. But 4 of the six files are not found for no apparent reason. And the two that are just don’t work. The client just returns to the menu after selecting that entry (just like it does for the .ISOs that were not found during the mount. Sigh!

    BTW, there are only 8 loop devices so I think some way to automount on use will end up being needed. And perhaps a way to unmount when not needed. Though I suspect I may never see enough activity to demand it, I like to do things where I avoid limits. I am looking forward to reading the other article now that I see the link.

    OH, and yes what you say makes sense. What do you think of my sed idea to fix that?

  9. Larry Thiel

    UPDATE

    I have it working and serving up 32 and 64 bit flavors of ubuntu 10.04, 10.10, and 11.04.

    I’m too tired now but will send you some details tomorrow. It looks like the limits are going to be the number of mounted ISOs since there are normally only 8 loop devices. I also wonder about resource consumption but have not looked at that at all.

    Goodnight

  10. Aviad

    glad to hear you have it working…

    FYI, the ISO mount thing is rather new… in the past we used to simply extract the files from the ISOs.

  11. Larry Thiel

    Yes, I know. The last two PXE servers I built worked that way which also meant each distro I was serving basically had 2 copies on the server. It also meant that I had to learn where different distros stored certain files in their .ISOs. I don’t know if you want details of what I did, but here they are:

    Added these lines to /etc/fstab after creating the mount point directories in /tftpboot/howtogeek/linux/
    /home/larry/isofiles/ubuntu/10.04/ubuntu-10.04.2-desktop-i386.iso /tftpboot/howtogeek/linux/ubu1004DL32 udf,iso9660 user,loop 0 0

    and these lines in /etc/exports
    /tftpboot/howtogeek/linux/ubu1004DL32 *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,no_subtree_check)
    /tftpboot/howtogeek/linux/ubu1004DL64 *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,no_subtree_check)
    /tftpboot/howtogeek/linux/ubu1010DL32 *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,no_subtree_check)
    /tftpboot/howtogeek/linux/ubu1010DL64 *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,no_subtree_check)
    /tftpboot/howtogeek/linux/ubu1104DL32 *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,no_subtree_check)
    /tftpboot/howtogeek/linux/ubu1104DL64 *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,no_subtree_check)

    Note the addition of the no-subtree_check to avoid a warning that was coming out in syslog. Also note that I placed all the .ISOs (maybe 100 of them) in a home directory tree so they did not need to be lost if I ever did a fresh install. I would have preferred /tftpboot/ to be there as well as in another PXE server I saw for the same reason but FOG made this so easy and I did not want to dig into there stuff to see what needed to change for them. Probably would not be hard though to move it all under a tftp user.

    I was not able to use mount points under .mnt/ or /media/ because syslinux menus apparently make assumptions for the relative location of mount points for PXE usage. Another reason to want these things in user space.

    My menu is simply adding to you linux.cfg but to expand the service would probably change that to be multiple menus and I had trouble when I tried that the first time. Anyway, here it is:

    Next steps:
    - try using autofs to dynamically mount and unmount .ISOs as needed and avoid the limit of 8 loop devices
    - try using dnsmasq and dnsmasq_proxy to respond to DHCP Requests for a PXE server without having to set that up in the actual DHCP Server (I was shown this working Saturday)
    - find a way to not require a static IP to encode into the menus (maybe the sed editing I mentioned before or whatever Brian did Saturday)

    Got this working with Mint10, but it’s strange. It loads the live environment fine, everything works… but when I install it, the network doesnt initialize. I had a hell of a time trying to manually enable the network. When I install it (same ISO) from a cd, everything is fine after the install. Would there be a difference on how the network drivers are loaded through a pxe boot?

  13. Aviad

    @Bobby
    no difference, its just an Ubuntu bug that popped up somewhere in the 10.04 time-frame. i guess it creeped its way into Mint due to lack of testing/reporting.

    to overcome the problem, you can do either one of two things post installation:

    1. edit the /etc/network/interfaces file and change the “manual” setting of the network card to DHCP. and then restart networking – this is the dark side of the fix, as in its quicker, faster and more seductive to implement, but has the disadvantage that some networking features don’t work the same as with a normal setup.

    2. go into the same file, comment out the network card entry. use ifconfig -a to find the MAC of the NIC and restart networking. then in the GUI go to preferences “network connections” and manually add the NIC with its MAC. – while longer to perform, this will get you up and running just as if you have installed using the CD.

    Hope this helps, and way to go on getting Mint on there :)

  14. Bobby

    Epic, worked perfect. I look forward to more articles on this. THANK YOU SO MUCH! :)

    I am having trouble getting Fedora to boot. Fedora is built differently and does not use casper. My menu entry is:

    LABEL Fedora 14 Gnome Livecd
    MENU LABEL Fedora 14 Gnome 32 bit Desktop (LIVE)
    KERNEL howtogeek/linux/fed14gnoL32/isolinux/vmlinuz0
    APPEND root=/dev/nfs boot=isolinux netboot=nfs nfsroot=192.168.2.201:/tftpboot/howtogeek/linux/fed14gnoL32 initrd=howtogeek/linux/fed14gnoL32/isolinux/initrd0.img quiet splash –

    It starts by loading the image but fails with a message of “No root device found. Boot has failed, sleeping forever”. Any ideas?

    BTW, Puppy 4.31, 5.20 and 5.25 also do not work but I have not looked into them yet.

    P.S. I had no luck using autofs but found a way to increase the number of loop devices (add max_loop=n to the kernel boot line in /etc/default/grub and update-grub). Not the best answer, but…

  16. Aviad

    @Larry Thiel
    ya, never did get live fedora to work… but didn’t need it that much, so didn’t try that hard. what I did do is get the net installer working from PXE… but if you really need the live version, i can’t help you and i really wish you good luck with that.

    as for Puppy, it at least used to have a “humongous” initrd version… so it is possible to send this humongous initrd through PXE to the client and not even use NFS… at least thats what i did back in the day.

    regarding the max loop devices, as i said… Linux has many ways to accomplish the same goal… if this one works for you , use it… :)

  17. Bobby

    LABEL Debian 6 Net Install
    MENU DEFAULT
    KERNEL howtogeek/linux/debian/debian6/debian/install.amd/vmlinuz

    Trying the Debian 6 net install, this boots fine (although I couldnt get the gtk graphical to work), the install menu comes up and allows me to choose the language, but then it asks for the CD… cant get past it.

  18. Aviad

    this is part of the weirding way that we will teach you…

    or in other words, part of a future guide :)

  19. Mark

    Thanks a million for the guides. Been trying to get a PXE server up and running for ages without success. I now have 3 versions of Ubuntu under Linux stuff as well as Parted Magic.

    I have a few small issues though changing the backround pictures.

    The master.cfg file points to fog/bd.png and the linux.cfg file points to howtogeek/pics/fog-sub.jpg

    If the master.cfg file is the global one surely it will always reverts to this image. I’ve placed my own image at howtogeek/pics/fog-sub.jpg but the sub menu always shows the fog/bd.png image.

    Also every time I try and point the master.cfg file to another image of the same size as fog/bd.png (both .png and .jpg) I only get a blank backround globally. fog/bd.png seems to be the only one that works. Could this be due to the file permissions? My image is owner = root whereas fog/bd.png’s owner = fog

    Thanks in advance.

  20. jay

    bobby, you need to make sure you download the initrd and kernel from http://ftp.nl.debian.org/debian/dists/squeeze/main/installer-amd64/current/images/netboot/debian-installer/amd64/

    IF it is not from the “netboot” tree it will require a cd.

    Hi – I hope you are still monitoring this thread.

    Mine didn’t work – boots into FOG but freezes. Before I go into the issue though, I would like to kinow if this is a typo -

    Append to “fstab” the ISO mount entry:

    /tftpboot/howtogeek/linux/ubuntu-11.04-desktop-amd64.iso /tftpboot/howtogeek/linux/ubuntu/11.04 udf,iso9660 user,loop 0 0

    /tftpboot/howtogeek/linux/ubuntu-11.04-desktop-amd64.iso /tftpboot/howtogeek/linux/ubuntu/11.04 udf,iso9660 user,loop 0 0

    Hope to hear from you soon

    fstab wouldn’t save?
    It doesn’t seem like any typo can cause that…
    and what you sent doesn’t look wrong, but it all depends on what is going on on your system.

    Thanks! However, I get: “Self Check failed! The File failed the check. Press OK to shutdown the system.”

    How do I fix this?

    Sorry, I’m an idiot. I was working on two different PXE boot issues and got them mixed up. LOL

    My REAL problem is, I followed your method to the letter, yet everything boots, I got rid of the splash screen so I could watch what was happening, and it seems that it never completes, because it is still looking for the live filesystem on CDROM!

    What do I need to change to get it to load the proper one from the nfs share?

    Thanks!

    Anyone?

    Still haven’t figured it out.

    I’m thinking this thread is dead… :(
