[SOLVED] PXE boot with pfSense and Slack

lpallard · 09-04-2010, 10:44 PM

Hello!

I am trying to setup a PXE booting environment in my network and I almost got it to work... Only it does not quite work yet... Basically, I want my laptop or any other machines to boot from my network. I followed the instructions from AlienBob to do so.

I setup my laptop to boot from the NIC, it automatically gets an IP from the DHCP server (pfSense);

I setup my gateway/DHCP server (pfSense) as is:
-The IP address from the network boot server: 192.168.0.101 (the server where my slackware mirror and all tftp boot files are)
-The filename used for network booting: /mnt/it-maintenance/tftpboot/slackware-13.1/pxelinux.0 (the absolute address of pxelinux.0 in my server)

I setup the network boot server (running slack 13.1) as is:
-uncommented the line in inetd.conf to have:

Code:

tftp  dgram   udp     wait    root    /usr/sbin/in.tftpd  in.tftpd -s /tftpboot -r blksize

-added a NFS share to /etc/exports to have:

Code:

/mnt/it-maintenance/operating-systems/slackware-13.1
192.168.0.106(ro,sync,insecure,all_squash)

-and finally in /mnt/it-maintenance/tftpboot/ I have a folder named slackware-13.1 which contains:

Code:

-rw-r--r-- 1 root root     1697 2010-07-04 22:26 README.TXT
-rw-r--r-- 1 root root       41 2010-07-04 22:26 VERSIONS.TXT
-rwxr-xr-x 1 root root     2311 2010-07-04 22:26 compile_kern.sh
-rw-r--r-- 1 root root      793 2010-07-04 22:26 f2.txt
drwxr-xr-x 2 root root      128 2010-09-04 21:53 huge.s
drwxr-xr-x 2 root root      128 2010-09-04 21:53 hugesmp.s
-rw-r--r-- 1 root root 16902288 2010-07-04 22:26 initrd.img
-rw-r--r-- 1 root root    99315 2010-07-04 22:26 loadlin16d.zip
-rw-r--r-- 1 root root      758 2010-07-04 22:26 message.txt
-rw-r--r-- 1 root root    16466 2010-01-25 15:34 pxelinux.0
drwxr-xr-x 2 root root       72 2010-09-04 21:54 pxelinux.cfg
drwxr-xr-x 2 root root      160 2010-09-04 21:53 speakup.s

Now when I try to boot from that my laptop complains with:

PXE-E32: TFTP open timeout

According to google, E32 error means that the machine found a boot file but could not download it...

What do I need to do to make it work???

tftp dgram udp wait root /usr/sbin/in.tftpd in.tftpd -s /tftpboot -r blksize

Note the -s /tftpboot that is more or less a chroot. All your tftpboot files have to
be located in /tftpboot.

Well that did it! but now I have a new problem...

I booted and got to the "boot:" prompt... I pressed enter to select the default hugesmp.s and it said:

Could not find kernel image: kernels/hugesmp.s/bxImage

and the content of pxelinux.cgf/default is:

Code:

default hugesmp.s
prompt 1
timeout 1200
display message.txt
F1 message.txt
F2 f2.txt
label huge.s
  kernel kernels/huge.s/bzImage
  append initrd=initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=huge.s
label hugesmp.s
  kernel kernels/hugesmp.s/bzImage
  append initrd=initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=hugesmp.s
label speakup.s
  kernel kernels/speakup.s/bzImage
  append initrd=initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=speakup.s

I imagine the "kernels" prefixes are wrong.. what should I modify to?

lpallard · 09-04-2010, 11:51 PM

got it! I just removed the /kernels from the addresses... the root was already at the good place... now that I can almost have a perfect setup I noticed before it display the welcome messages, I see some messages:

Code:

Trying to load: pxelinux.cfg/01-00-a0-cc-de-21-39
Trying to load: pxelinux.cfg/C0A8010F

Trying to load: pxelinux.cfg/C0A
Trying to load: pxelinux.cfg/C0
Trying to load: pxelinux.cfg/C
Trying to load: pxelinux.cfg/default

what does it mean?

XGizzmo · 09-05-2010, 06:34 AM

That is pxelinux looking for a specific configuration based on mac address then ip address in hex.

lpallard · 09-05-2010, 09:56 AM

So it does not represent a problem then?

Now that I have a working setup, how complicated it would be to have the opportunity to boot other kind of troubleshooting appz like clonezilla, slax live distro, UBCD, etc??

No, that text does not indicate a problem - on the contrary it shows that you can create a per-computer PXE configuration file, instead of using the file "default" for all connecting PXE clients.

Just add more boot entries to your pxelinux.cfg/default file (and copy the corresponding kernels/images into your /tftpboot directory).

For instance, this is my /tftpboot/pxelinux.cfg/default file:

Code:

default hugesmp.s
prompt 1
timeout 1200
display slackware64-current/message.txt
F1 f1.txt
F2 slackware-current/f2.txt
F3 slackware64-current/f2.txt
F4 pmagic-pxe-4.5/boot/syslinux/message.txt
F5 pmagic-pxe-4.5/boot/syslinux/message2.txt
F6 pmagic-pxe-4.5/boot/syslinux/message3.txt
F7 pmagic-pxe-4.5/boot/syslinux/message4.txt
F8 pmagic-pxe-4.5/boot/syslinux/message5.txt

label huge.s
  kernel slackware-current/kernels/huge.s/bzImage
  append initrd=slackware-current/initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=huge.s

label hugesmp.s
  kernel slackware-current/kernels/hugesmp.s/bzImage
  append initrd=slackware-current/initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=hugesmp.s

label slack64

  append initrd=pmagic-pxe-4.5/pmagic/initramfs load_ramdisk=1 prompt_ramdisk=0 rw sleep=10 livemedia

label memtest
  kernel memtest/memtest

and this is my f1.txt:

Code:

hey Eric! Thanks for the instructions! Precious stuff...
I guess since I am going deeper into this, now I have several questions:

1-I added Clonezilla to my PXE setup and it kinda works but when I type "clonezilla" to the boot: prompt, it seems to load the kernel and work fine until I can read "Enter 1 to select a keyboard map". From a USB keyboard, I wont be able to type anything at this point...
Is this normal that the USB attached keyboard does not work? it works with all the other slackware kernels...

Edit to #1: Solved.. it does that for anything before the USB driver is loaded..

2-Also just before this prompt, I can read:

Code:

/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?
Failure to communicate with Kernel device-mapper driver.

Is that normal?

Thanks Eric (and all the others) for your help!
