KNOPPIX Terminal Server
Preamble
- This page will be used to document and describe how to boot KNOPPIX off the network using Samba as opposed to NFS.
- The page will pull from several resources to provide an official reference at the KNOPPIX site for all to use.
- Just starting so page will be in progress for a bit and will need to be catagorized.
- You are welcome to contact me on model (I have a day job, so please bare with me see Rjent).
Model
- Most of the this information is an exert from a paper on the model at http://www.mgr3.k12.mo.us/~rjn103s/HybridNotes-20060504-1.pdf
The methodology for the hybrid environment uses a Common Internet File System (CIFS) to boot up KNOPPIX. The base work for this model utilizes existing resources and information from http://knoppix.manty.net . The setup information provided here assumes you have PXE booting via TFTP already setup on the boot server. The rest is as follows:
- KNOPPIX:
Download KNOPPIX 4.0.2 (or newer) and burn to a CD.
Download the miniroot.gz and integrate for the pxe bootup. To do this, place the miniroot.gz in the /tftpboot/hybrid/pxeboot/ directory. Make a directory under /tftpboot/hybrid/pxeboot/ called knoppix and copy the /boot/isolinux/linux file from the KNOPPIX CD to /tftpboot/hybrid/pxeboot/knoppix/
Copy the KNOPPIX folder from the KNOPPIX CD to a location on server of /hybrid/knoppixshare
Modify the pxe boot menu located at /tftpboot/hybrid/pxeboot/pxelinux.cfg with the below addition:
LABEL Knoppix CIFS KERNEL knoppix/linux APPEND secure nfsdir=//xxx.xxx.xxx.xxx/knoppix_share nodhcp lang=en ramdisk_size=100000 init=/etc/init apm=poweroff nomce vga=791 initrd=miniroot.gz quiet BOOT_IMAGE=knoppix
Note1: the above APPEND line must appear as a single line in your pxelinux.cfg/default file
Note2: xxx.xxx.xxx.xxx is the IP address of the server running the samba share.
- Samba
Samba provides the CIFS services, so we setup a share on server xxx.xxx.xxx.xxx. An example smb.conf is listed below:
[global] workgroup = HYBRIDGROUP netbios name = HYBRIDSERVER security = share guest account = nobody [knoppix_share] comment = Knoppix Boot Data path = /hybrid/knoppix_share read only = Yes guest ok = Yes
Note: After changes to smb.conf you will need to restart samba services.
- DHCP Services
Example entry for dhcpd.conf below
group { filename "hybrid/pxeboot/pxelinux.0"; host hybrid51 { hardware ethernet MA:CA:DD:RE:SS:ED; fixedaddress xxx.xxx.xxx.xxx; } }
Note: After changes to dhcpd.conf restart or reload dhcp services.
At this point, you should be ready to test boot your KNOPPIX session.
