# PXE Server
|
|
|
|
## Setup with existing DHCP server
|
|
|
|
|
|
|
|
If another DHCP server is already present and is not providing PXE-Services dnsmasq can be configured to supply the information regarding the PXE server and also supply said TFTP server. The following `dnsmasq.conf` file can be used.
|
|
|
|
|
|
|
|
```config
|
|
|
|
port=0
|
|
|
|
dhcp-range=192.168.1.0,proxy
|
|
|
|
dhcp-option=vendor;PXEClient,6,2b
|
|

## Distributions
|
|
|
|
|
|
|
|
### Kubuntu/Xubuntu
|
|
|
|
|
|
|
|
Xubuntu is equivalent to Kubuntu, only another image has to be used and the seed-file has to be changed.
|
|
|
|
|
|
|
|
- download image from ftp.tu-chemnitz.de/pub/linux/ubuntu-cdimage/kubuntu/releases or equivalent
|
|
|
|
- extract image and set permissions
|
|
|
|
```bash
|
|
|
|
$ 7z x -o$EXTRACTPATH $IMAGE.iso
|
|
|
|
$ chmod a+rX -R $PATH
|
|
|
|
```
|
|
|
|
- create symlink in TFTP-folder
|
|
|
|
```bash
|
|
|
|
$ ln -s $EXTRACTPATH/casper/initrd.lz $TFTP/kubuntu
|
|
|
|
$ ln -s $EXTRACTPATH/casper/vmlinuz.efi $TFTP/kubuntu
|
|
|
|
```
|
|
|
|
- add the `pxelinux.cfg/default`-entry
|
|
|
|
```pxe

|
|

|
KERNEL /kubuntu/vmlinuz.efi

|
APPEND initrd=/kubuntu/initrd.lz nfsroot=$SERVER:$EXTRACTPATH/ netboot=nfs file=/cdrom/preseed/kubuntu.seed boot=casper --
|
