## hostname is *localhost* in JeOS node
The hostname is not set to the dns name on an image create by JeOS.
This can be changed by setting the value *DHCLIENT_SET_HOSTNAME="no"* 
to *DHCLIENT_SET_HOSTNAME="yes"*
in the file 
```
/etc/sysconfig/network/dhcp
```
This file is most likely created with the template
```
/usr/share/fillup-templates/sysconfig.dhcp-network
```
where the value *DHCLIENT_SET_HOSTNAME="no"* is set and not changed as this happens with yast? in a normal setup.

## kiwi commanline order
The image can be modifed after the build step by modifying the root directory. The command for this is 
```
kiwi --type=oem system create --root=/tmp/jeos15_image3/build/image-root/  \
--target-dir=/tmp/jeos15_image3/
```
and not 
```
kiwi system create --root=/tmp/jeos15_image3/build/image-root/  \
--target-dir=/tmp/jeos15_image3/ --type=oem
```
so the *--typ=oem* is a positional dependened argument.

The deployment tool `clustduct` connects the `genders` database to the `dnsmasq` service. During initialization the files `/etc/ethers` and `/etc/hosts` are populated by `node` entries from the genders database. `clustduct` also monitors *tftp* file transfers and can so be used to deploy prebuilt images to `compute nodes`.

## components of `clustduct`
The central component of `clustduct` is the script
`/usr/sbin/clustduct.lua`
and is called directly by `dnsmasq` at every dhcp and tftp activity of `dnsmasq`.

Two scripts are used to create and maintain the directory and file structure for booting and installing the `compute nodes`. In order to copy the files from the `syslinux` package the shell script
```
/usr/sbin/prepare_tftp.sh
```
can be used. For the creation of the files used for `grub` or PXE the `lua` script
```
/usr/sbin/write_bf.lua
```
can be used. It can be used with following command line options

option | description
-------|--------------------------------------------------
-n NODE| create configuration only for given and not all nodes
-o DIRECTORY| base directory to write boot file to
-c DIRECTORY| search directory for configuration files

## configuration of `clustduct`
The script 
```
/usr/sbin/clustduc.lua
```
can be configured with the file
```
/etc/clustduct.conf
```
which is not parsed, but is itself a `lua` table. Following values can be used

option  | description
--------|--------------------------------------------------
ethers | location of the ethers files, default is `/etc/ethers`
hosts | location of the hosts files, default is `/etc/hosts`
genders |location of the genders database, default is `/etc/genders` 
domain | domain to which the nodes are expanded, *must* be the same as in `/etc/dnsmasq.conf`
linear_add | if *true*, nodes with unknown `mac` addresses will be added to the `genders` database
confdir | the directory where clustduct searches for template files, `/etc/clustduct.d/` is used as default

## template files

During the initializaton of `clustduct` or by calling `write_bf.lua` individual entries for every node are created. As templates for the menus shown at boot time, two files are used:
For the PXE boot, the file
```
/etc/clustduct.d/pxe_iptemplate
``` 
and for `grub` the file
```
/etc/clustduct.d/grub_iptemplate
```
is used. Following values are substituted

value | description
------|--------------------------------------------------
$NODE | replaced with node name
$MAC  | replaced with mac address
$IP   | replaced with ip address



## genders database
The genders database is the single flat file located under `/etc/genders`. The format is
```
IDENTIFICATION KEY=VALUE
```
as *IDENTIFICATION* the name of the node or image is used. The node entry will be expanded to the FQDN. For the use of `clustduct` every node needs a single entry for every `KEY` and `VALUE` as the scripts may add and delete whole lines. An example database is shown below:

```
compute-01 ip=192.168.100.11
compute-02 ip=192.168.100.12
compute-03 ip=192.168.100.13
compute-03 mac=aa:bb:cc:dd:ee:ff
```

### special node entries

value | description
------|--------------------------------------------------
ip | used a ip address, *must* be present for node entry
mac | used as for dhpd
install | image entry which be used as default boot for node, inferior to boot
boot | image entry for boot, takes precedence over install entry


### special characters

As `genders` does not allow white spaces and other special characters, so following translation table is used

character | character description | value in `genders`
----------|-----------------------|-------------------
' ' | whitespace | \\ws
= | equals | \\eq

### image and boot entries

If an IDENTIFICATION in the `genders` database has KEY called 'menu' it is interpreted as a boot entry for `grub` called from (U)EFI and/or pxe network boot. Following values used for the boot entries are common for PXE and `grub`. All values which are not listed below will be ignored.

value | description
------|--------------------------------------------------
menu | will be expanded the label of menu
kernel | kernel which be used to boot, could also be a chainloader
append | options appended to the kernel entry
mandatory | will be added to *all* node entries
nextboot | will be used as boot entry after trigger event
trigger | download if file name will be used as trigger event



#### Options for PXE boot

value | description
------|--------------------------------------------------
com32 | used instead of kernel, used for chainloading
initrd | used as initrd in the append entry

#### Options for `grub` entries called from EFI

value | description
------|--------------------------------------------------
initrdefi | used as initrdefi
set | used as set, like timeouts ...
chainloader | the used chainloader entries
grub | value is used without directly without 'grub'

## Prerequisites
Configure a *nfs-server* with following *exports*
```
/usr/lib/hpc	*(ro,root_squash,sync,no_subtree_check)
/usr/share/lmod/modulefiles	*(ro,root_squash,sync,no_subtree_check)
/usr/share/lmod/moduledeps	*(ro,root_squash,sync,no_subtree_check)
```

## Salt formulas
The salt formula */srv/salt/compute-node.sls* is used to configure the compute nodes. The formula has the contents
```

```
and the definition for the node as *srv/salt/top.sls*
```
base:
  'compute-[0-2][0-9].cluster.suse':
    - compute-node

```
we also have to create the configuration files for *lua-lmod* with
```
mkdir /srv/salt/shared_module
cp /etc/profile.d/lmod* /srv/salt/shared_module
```
and create a pillar for distributing the genders database by creating the file `/srv/pillar/top.sls` with the content
```
base:
  '*':
    - genders
```
and the genders pillar `/srv/pillar/genders.sls`
```
genders:
    database: |
        {{ salt['cmd.run']('nodeattr --expand' ) | indent(8) }}
```
Now accept the key with
```
salt-key -A
```
and the node should install the rest.

To deploy a cluster with `clustduct`, following prerequisites must be met:

   * internet access
   * separate network without an active dhcp server
     * *gateway* of the *cluster network*
   * *DNS* server outside of the cluster network

In this setup one node, from now on called *managment server*, provides *DNS* and *dhcp* information to the other nodes, called *compute nodes*.  The *managment server* is also used to generate images with *kiwi* and provide them to the *compute nodes*.

## Table of used values

Key | Example value | Used value
----|---------------|----------------
*cluster network* | 192.168.100.0/24 | ___________
*gateway*         | 192.168.100.1 |___________
*DNS server*      | 192.168.100.1 |___________
*dynamic range*   | 192.168.100.50-60 |___________
*static address*  | 192.168.100.254 |___________
*domain*          | cluster.suse |___________

## Setup of *managment server*
The *managment server* may be installed via the *HPC Managment Server (Head Node)* role, but other means of setup are also possible.

After installing the package `clustduct`, all necessary components are available.
Following services must be **disabled**

  * firewall
  * apparmor

Following packages must be installed:

  * python3-kiwi

Following services must be **enabled** and **running**

  * sshd

Following service must be **enabled**

  * dnsmasq

Furthermore, set up a static IP address.

  * static ip address


NOTE: Disable apparmor

In some profiles, `apparmor` is installed and has a preconfigured profile for `dnsmasq`. It must be disabled which can be done in two ways.

   * The profile for `dnsmasq` can be disabled with
```
aa-disable /etc/apparmor.d/usr.sbin.dnsmasq
```
   * or the `apparmor` service can be disabled with

```
systemctl disable apparmor.service
```
afterwards the machine must be rebooted.

WARNING: Disabling the `apparmor` profile introduces security issues which can be ignored as the *cluster network* is assumed to be a protected network.

## Dnsmasq configuration
The package *clustduct* contains also an example configuration for *dnsmasq* in `/usr/share/doc/clustduct/dnsmasq.example` which has following differences to shipped *dnsmasq* configuration:

  * local domain (modify to your needs)
```
local=/cluster.suse/
```
  * dynamic range (modify to your needs)
```
dhcp-range=192.168.100.50,192.168.100.60,12h
```
  * tftp enabled and deployment directory
```
enable-tftp
tftp-root=/srv/tftpboot/
```
  * pxe boot option for *x86_64*
```
dhcp-boot=pxelinux.0
```
  * *clustduct* script
```
dhcp-luascript=/usr/sbin/clustduct.lua
```
  * enable mac management
```
read-ethers
```
  * `dnsmasq` is executed as root
```
user=root
group=root
```
  * *gateway* for the *cluster network* (modify to your needs)
```
dhcp-option=option:router,192.168.100.1
```

Once dnsmasq has been configured, it may be (re)started.

## `genders` databases for the node configuration
The genders database connects the *mac* addresses of the *compute nodes* with the *ip* address and the corresponding FQDN . A flat file in `/etc/genders` is used as database. If the mac addresses of the hosts are known they may also be added before the node installation, if not they can be set during the boot process or, depending on the configuration, will be added in linear manner.

### Adding known `mac` addresses to `genders`
Previosily known `mac` addresses of nodes may be added to the database by adding a single line which contains the node name and mac address to the file `/etc/genders`. The format must be like
```
NODENAME mac=$MACADDRESS
```
After editing the `genders` database it is advisable to check its syntax by
executing `nodeattr -k`.

## Install image creation
Sample kiwi configurations for creating images can be found under the directory
```
/usr/share/doc/clustduct/kiwi-descriptions/SUSE/
```
and
```
/usr/share/doc/clustduct/kiwi-descriptions/openSUSE/
```
The install image is prepared with
```
cd /usr/share/doc/clustduct
kiwi --type oem system prepare\
--description kiwi-descriptions/suse/x86_64/suse-leap-15.0-JeOS \
--root /tmp/leap15_oem_pxe
```
Now the root file system for the new nodes is available under `/tmp/leap15_oem_pxe` and simple modifications can be made to it, but they will be lost if a new system is created via the `kiwi system prepare` command. To install the *compute nodes* the image has to be packed. This is done with the commands:
```
mkdir /tmp/packed_image
kiwi --type=oem system create --root=/tmp/leap15_oem_pxe  \
--target-dir=/tmp/packed_image
```

## Preparing the *tftboot* directory
For the deployment of the *compute nodes* the *tftpboot* directory `/srv/tftpboot` must be prepared with the command 
```
prepare-tftp.sh
``` 
which installs the necessary files for booting and installing the *compute nodes* over the network via *PXE* or *UEFI*. Finally the directory which holds the image for the *compute nodes* must be created with
```
mkdir -p /srv/tftpboot/leap15/
```
and the previously packed image extracted to
```
cd /srv/tftpboot/leap15/
tar xJf /tmp/packed_image/LimeJeOS-Leap-15.0.x86_64-1.15.0.install.tar.xz

```
it.

The deployment tool `clustduct` connects the `genders` database to the `dnsmasq` service.

[genders](https://github.com/chaos/genders) is a static cluster configuration database used for cluster configuration management. The basic concept is that a
genders file, usually `/etc/genders/` containing a list of node names and their attributes is easily readable with the command `nodeattr`.

[dnsmasq](git://thekelleys.org.uk/dnsmasq.git) provides a DNS forwarder, DHCP server, router advertisement and network boot features for small computer networks.

The configuration of both to work properly with clustduct will be detailed further below. If you are already using
both tool, you'll see no special requirements are needed to integrating them with clustduct.

## How does clustduct works
During the initialization of every node, the files `/etc/ethers` and `/etc/hosts` are populated by the data provided by the `node` entries from the genders database. `clustduct` will also monitor *TFTP* file transfers and can be used to deploy prebuilt images to the `compute nodes`.

### components of `clustduct`
The central component of `clustduct` is the script `/usr/sbin/clustduct.lua`
and is called directly by `dnsmasq` at every DHCP and TFTP activity of `dnsmasq`.

Two scripts are used to create and maintain the directory and file structure for booting and installing the `compute nodes`.

* The shell script `/usr/sbin/prepare_tftp.sh`, in order to copy the files from the `syslinux` package

* The `lua` script `/usr/sbin/write_bf.lua` for the creation of the files used for `grub` or PXE.
The following command line options are available:

option | description
-------|--------------------------------------------------
-n NODE| create configuration only for given and not all nodes
-o DIRECTORY| base directory to write boot file to
-c DIRECTORY| search directory for configuration files

### configuration of `clustduct`
The script  `/usr/sbin/clustduct.lua` can be configured with the file `/etc/clustduct.conf`
which is not parsed, but is itself a `lua` table. The following values can be used:

option  | description
--------|--------------------------------------------------
ethers | location of the ethers files, default is `/etc/ethers`
hosts | location of the hosts files, default is `/etc/hosts`
genders |location of the genders database, default is `/etc/genders`
domain | domain to which the nodes are expanded, *must* be the same as in `/etc/dnsmasq.conf`
linear_add | if *true*, nodes with unknown `mac` addresses will be added to the `genders` database
confdir | the directory where clustduct searches for template files, default is `/etc/clustduct.d/`

### template files

During the initialization of `clustduct` or by calling `write_bf.lua` individual entries for every node are created. As templates for the menus shown at boot time, two files are used:

* For the PXE boot, the file `/etc/clustduct.d/pxe_iptemplate`

* For `grub` the file `/etc/clustduct.d/grub_iptemplate` with the following values being substituted

value | description
------|--------------------------------------------------
$NODE | replaced with node name
$MAC  | replaced with mac address
$IP   | replaced with ip address


## Working with the genders database
The genders database is the single flat file located under `/etc/genders`. The format is
```
IDENTIFICATION KEY=VALUE
```
as *IDENTIFICATION* the name of the node or image is used. The node entry will be expanded to the FQDN. For the use of `clustduct`, every node needs a single entry for every `KEY` and `VALUE` as the scripts may add and delete whole lines. An example database is shown below:

```
compute-01 ip=192.168.100.11
compute-02 ip=192.168.100.12
compute-03 ip=192.168.100.13
compute-03 mac=aa:bb:cc:dd:ee:ff
```

### special node entries

value | description
------|--------------------------------------------------
ip | used a IP address, *must* be present for node entry
mac | used as for DHCP
install | image entry which be used as default boot for node, inferior to boot
boot | image entry for boot, takes precedence over install entry


### special characters

As `genders` does not allow white spaces and other special characters, the following translation table is used:

character | character description | value in `genders`
----------|-----------------------|-------------------
' ' | whitespace | \\ws
= | equals | \\eq

### image and boot entries

If an *IDENTIFICATION* in the `genders` database has KEY called 'menu' it is interpreted as a boot entry for `grub` called from (U)EFI and/or PXE network boot.
The following values used for the boot entries are common for PXE and `grub`. All values which are not listed below will be ignored.

value | description
------|--------------------------------------------------
menu | will be expanded the label of menu
kernel | kernel which be used to boot, could also be a chainloader
append | options appended to the kernel entry
mandatory | will be added to *all* node entries
nextboot | will be used as boot entry after trigger event
trigger | download if file name will be used as trigger event



#### Options for PXE boot

value | description
------|--------------------------------------------------
com32 | used instead of kernel, used for chainloading
initrd | used as initrd in the append entry

#### Options for `grub` entries called from EFI

value | description
------|--------------------------------------------------
initrdefi | used as initrdefi
set | used as set, like timeouts ...
chainloader | the used chainloader entries
grub | value is used without directly without 'grub'



## Bare metal deployment with dnsmasq and kiwi
To deploy a cluster with `clustduct`, following prerequisites must be met:

  * internet access
  * separate network without an active DHCP server
  * *gateway* of the *cluster network*
  * *DNS* server outside of the cluster network

In this setup one node, called *management server*, provides *DNS* and *DHCP* information to the other nodes, called *compute nodes*. This *management server* is also used to generate images with [kiwi](https://opensuse.github.io/kiwi/) and provide them to the *compute nodes*.

### Table of used values

Key | Example value | Used value
----|---------------|----------------
*cluster network* | 192.168.100.0/24 | ___________
*gateway*         | 192.168.100.1 |___________
*DNS server*      | 192.168.100.1 |___________
*dynamic range*   | 192.168.100.50-60 |___________
*static address*  | 192.168.100.254 |___________
*domain*          | cluster.suse |___________

### Setup of *management server*
The *management server* may be installed via the *HPC Management Server (Head Node)* role, but other means of setup are also possible.

After installing the package `clustduct`, all necessary components are available.
The following services must be **disabled**

  * firewall
  * apparmor

The following packages must be installed:

  * python3-kiwi

The following services must be **enabled** and **running**

  * sshd

And the following service must be **enabled**

  * dnsmasq

Furthermore, set up a static IP address.

  * static IP address


#### Disabling apparmor

In some profiles, `apparmor` is installed and has a pre-configured profile for `dnsmasq`. It must be disabled which can be done in two ways.

   * The profile for `dnsmasq` can be disabled with
```
aa-disable /etc/apparmor.d/usr.sbin.dnsmasq
```
   * or the `apparmor` service can be disabled with
```
systemctl disable apparmor.service
```
afterwards the machine must be rebooted.

WARNING: Disabling the `apparmor` profile introduces security issues which can be ignored as the *cluster network* is assumed to be a protected network.

## Dnsmasq configuration
The package *clustduct* contains also an example configuration for *dnsmasq* in `/usr/share/doc/clustduct/dnsmasq.example` which has following differences to shipped *dnsmasq* configuration:

  * local domain (modify to your needs)
```
local=/cluster.suse/
```
  * dynamic range (modify to your needs)
```
dhcp-range=192.168.100.50,192.168.100.60,12h
```
  * tftp enabled and deployment directory
```
enable-tftp
tftp-root=/srv/tftpboot/
```
  * pxe boot option for *x86_64*
```
dhcp-boot=pxelinux.0
```
  * *clustduct* script
```
dhcp-luascript=/usr/sbin/clustduct.lua
```
  * enable mac management
```
read-ethers
```
  * `dnsmasq` is executed as root
```
user=root
group=root
```
  * *gateway* for the *cluster network* (modify to your needs)
```
dhcp-option=option:router,192.168.100.1
```

Once dnsmasq has been configured, it may be (re)started.

### `genders` databases for the node configuration
The genders database connects the *mac* addresses of the *compute nodes* with the *ip* address and the corresponding FQDN . A flat file in `/etc/genders` is used as database. If the mac addresses of the hosts are known they may also be added before the node installation, if not they can be set during the boot process or, depending on the configuration, will be added in linear manner.

### Adding known `mac` addresses to `genders`
Previously known `mac` addresses of nodes may be added to the database by adding a single line which contains the node name and mac address to the file `/etc/genders`. The format must be like
```
NODENAME mac=$MACADDRESS
```
After editing the `genders` database it is advisable to check its syntax by
executing `nodeattr -k`.

## Install image creation
Sample kiwi configurations for creating images can be found under the directory
```
/usr/share/doc/clustduct/kiwi-descriptions/SUSE/
```
and
```
/usr/share/doc/clustduct/kiwi-descriptions/openSUSE/
```
The install image is prepared with
```
cd /usr/share/doc/clustduct
kiwi --type oem system prepare\
--description kiwi-descriptions/suse/x86_64/suse-leap-15.0-JeOS \
--root /tmp/leap15_oem_pxe
```
Now the root file system for the new nodes is available under `/tmp/leap15_oem_pxe` and simple modifications can be made to it, but they will be lost if a new system is created via the `kiwi system prepare` command. To install the *compute nodes* the image has to be packed. This is done with the commands:
```
mkdir /tmp/packed_image
kiwi --type=oem system create --root=/tmp/leap15_oem_pxe  \
--target-dir=/tmp/packed_image
```

## Preparing the *tftboot* directory
For the deployment of the *compute nodes* the *tftpboot* directory `/srv/tftpboot` must be prepared with the command
```
prepare-tftp.sh
```
which installs the necessary files for booting and installing the *compute nodes* over the network via *PXE* or *UEFI*. Finally the directory which holds the image for the *compute nodes* must be created with
```
mkdir -p /srv/tftpboot/leap15/
```
and the previously packed image extracted to
```
cd /srv/tftpboot/leap15/
tar xJf /tmp/packed_image/LimeJeOS-Leap-15.0.x86_64-1.15.0.install.tar.xz

```
it.



# Configuration management with salt
## Prerequisites
Configure a *nfs-server* with following *exports*
```
/usr/lib/hpc	*(ro,root_squash,sync,no_subtree_check)
/usr/share/lmod/modulefiles	*(ro,root_squash,sync,no_subtree_check)
/usr/share/lmod/moduledeps	*(ro,root_squash,sync,no_subtree_check)
```

## Salt formulas
The salt formula */srv/salt/compute-node.sls* is used to configure the compute nodes. The formula has the contents
```
nfs-client:

      - mode: 644
      - user: root
      - group: root
      - require:
        - pkg: genders
```
and the definition for the node as *srv/salt/top.sls*
```
base:
  'compute-[0-2][0-9].cluster.suse':
    - compute-node

```
we also have to create the configuration files for *lua-lmod* with
```
mkdir /srv/salt/shared_module
cp /etc/profile.d/lmod* /srv/salt/shared_module
```
and create a pillar for distributing the genders database by creating the file `/srv/pillar/top.sls` with the content
```
base:
  '*':
    - genders
```
and the genders pillar `/srv/pillar/genders.sls`
```
genders:
    database: |
        {{ salt['cmd.run']('nodeattr --expand' ) | indent(8) }}
```
Now accept the key with
```
salt-key -A
```
and the node should install the rest.

## Path:	Network/DHCP/DHCP client
## Description:	DHCPv4 client configuration variables
#
# Note: 
# To configure one or more interfaces for DHCP configuration, you have to
# change the BOOTPROTO variable in /etc/sysconfig/network/ifcfg-<interface>
# to 'dhcp' (and possibly set STARTMODE='onboot'). 
#
# Most of the options can and should be overridden by per-interface
# settings in the ifcfg-* files.
#
# Note: NetworkManager is not using any sysconfig settings.
#

## Type:	yesno
## Default:	no
#
# Should the DHCPv4 client set the hostname? (yes|no)
# 
# When it is likely that this would occur during a running X session, 
# your DISPLAY variable could be screwed up and you won't be able to open
# new windows anymore, then this should be "no". 
#
# If it happens during booting it won't be a problem and you can 
# safely say "yes" here. For a roaming notebook with X kept running, "no"
# makes more sense. 
#
DHCLIENT_SET_HOSTNAME="yes"

## Type:	string
## Default:	AUTO
#
# Specifies the hostname option field when DHCPv4 client sends messages.
# Some DHCP servers will update nameserver entries (dynamic DNS) to it.
# Also, some DHCP servers, notably those used by @Home Networks, require
# the hostname option field containing a specific string in the DHCP
# messages from clients.
#
# When set to "AUTO", the current hostname from /etc/hostname is sent.
# Use this variable to override it with another hostname, or leave it
# empty to not send any hostname.
#
DHCLIENT_HOSTNAME_OPTION="AUTO"

## Type:	yesno
## Default:	yes
#
# Should the DHCP client set a default route (default Gateway) (yes|no)
#
# When multiple copies of dhcp client run, it would make sense that only
# one of them does it. 
#
DHCLIENT_SET_DEFAULT_ROUTE="yes"

## Type:        integer
## Default:     "0"
#
# This option allows to set a metrics/priority for DHCPv4 routes.
#
DHCLIENT_ROUTE_PRIORITY="0"

## Type:	string
## Default:	""
#
# specify a client ID
#
# Specifies a client identifier string. By default an id derived from the
# hardware address of the network interface is sent as client identifier.
#
DHCLIENT_CLIENT_ID=""

## Type:	string
## Default:	""
#
# Specifies the vendor class identifier string. The default is dhcp client
# specific.
#
DHCLIENT_VENDOR_CLASS_ID=""

## Type:        list<rfc3004,string>
## Default:     string
#
# Specifies the format of the DHCLIENT_USER_CLASS_ID variable.
#
# The DHCPv4 option and it's format is specified by RFC3004 as an array
# of class identifiers, but most DHCP clients/servers aren't compliant
# with the specification and send/expect a single string without proper
# RFC3004 length-value tuple format instead.
#
# When set to "rfc3004" DHCLIENT_USER_CLASS_ID[SUFFIX] permit an RFC
# compliant array, otherwise DHCLIENT_USER_CLASS_ID is used as string.
#
DHCLIENT_USER_CLASS_FORMAT=""

## Type:        string
## Default:     ""
## Suffix:      yes
#
# Specifies the user class identifier (array) to send in dhcp requests.
# The DHCLIENT_USER_CLASS_FORMAT variable specified how to interpret it.
#
DHCLIENT_USER_CLASS_ID=""

## Type:	integer
## Default:	""
#
# Specifies the lease time (in seconds), that is suggested to the
# server. Default is to use the lease time offered by the server.
#
DHCLIENT_LEASE_TIME=""

## Type:        yesno
## Default:     yes
#
# This setting controls whether dhcp client should try to use DHCP settings
# provided in its last lease when the dhcp-server is not reachable and
# the lease hasn't expired yet.
# Set this variable to "no" to disable the fallback to the last lease.
#
DHCLIENT_USE_LAST_LEASE="yes"

## Type:	yesno
## Default:	no
#
# Send a DHCPRELEASE to the server (sign off the address)? (yes|no)
# This may lead to getting a different address/hostname next time an address
# is requested. But some servers require it.
#
DHCLIENT_RELEASE_BEFORE_QUIT="no"

## Type:	integer
## Default:	0
#
# Some interfaces need time to initialize and/or do not report correct status.
# Add the latency time in seconds so these can be handled properly. Should
# probably set per interface rather than here.
# This setting causes a sleep time before dhcp clients are started regardless
# of the link status.
#
# Note: RFC 2131 specifies, that the dhcp client should wait a random time
# between one and ten seconds to desynchronize the use of DHCP at startup.
# We do not use this initial delay to not slow down start/boot time.
#
DHCLIENT_SLEEP="0"

## Type:	integer
## Default:	15
#
# The DHCPv4 client will try to get a lease for DHCLIENT_WAIT_AT_BOOT seconds,
# then inform ifup waiting for it, that it continues in background.
# When you increase this time, increase also the WAIT_FOR_INTERFACES variable
# e.g. to a value twice as high as the time specified here.
#
DHCLIENT_WAIT_AT_BOOT="15"

## Type:	integer
## Default:	"0"
#
# The DHCPv4 client will stop processing / fail after this time when it does
# not get a reply from the dhcp server. Before you set this variable, take a
# look at DHCLIENT_WAIT_AT_BOOT allowing to continue in background instead.
#
DHCLIENT_TIMEOUT="0"

## Path:	Network/DHCP/DHCPv6 client
## Description:	Global DHCPv6 client configuration

## Type:        list(auto,managed,info)
## Default:     auto
#
# This option allows to specify the request mode used by the DHCPv6
# client when the BOOTPROTO is set to dhcp or dhcp6, and overrides
# the "Managed Address Configuration" and the "Other Configuration"
# flags provided by the IPv6 router its Router Advertisement (RA)
# for the network connected to this interface.
#
#   auto:    follow RA flags, remain silent when no RA flag is set
#   info:    request other configuration (dns,ntp) only, no IP address
#   managed: request IP address as well as other configuration
#
DHCLIENT6_MODE="auto"

## Type:        yesno
### Default:     yes
#
# This option allows the DHCPv6 client to indicate its desire to accept
# rapid commit leases using two-packet exchange (solicitation, lease ack)
# instead of the four packet (solicitation, offer, request, lease ack).
#
DHCLIENT6_RAPID_COMMIT="yes"

## Type:	yesno
## Default:	no
#
# Should the DHCPv6 client set the hostname? (yes|no)

#
DHCLIENT6_SET_HOSTNAME="no"

## Type:        string
### Default:     AUTO

# Specifies the hostname option field when DHCPv6 client sends messages.
# Some DHCP servers will update nameserver entries (dynamic DNS) to it.
#
# When set to "AUTO", the current hostname from /etc/hostname is sent.
# Use this variable to override it with another hostname, or leave it
# empty to not send any hostname.
#
DHCLIENT6_HOSTNAME_OPTION="AUTO"

## Type:        integer
### Default:     ""
#
# Specifies the preferred lifetime (in seconds) used as T1/renewal
# (1/2 of it) and T1/rebind (4/5 of it) in DHCPv6 IA NA requests.
#
# Default is to not propose anything but use the times as offered
# by the DHCPv6 server.
#
DHCLIENT6_LEASE_TIME=""

## Type:        yesno
## Default:     yes
#
# This setting controls whether DHCPv6 client should try to use settings
# provided in its last lease when the DHCPv6-server is not reachable and
# the lease hasn't expired yet.
# Set this variable to "no" to disable the fallback to the last lease.
#
DHCLIENT6_USE_LAST_LEASE="yes"

## Type:	yesno
## Default:	no
#
# Send a DHCPv6 RELEASE to the server (sign off the address)? (yes|no)
# This may lead to getting a different address/hostname next time an address
# is requested. But some servers require it.
#
DHCLIENT6_RELEASE_BEFORE_QUIT="no"

## Type:	integer
## Default:	0
#
# Some interfaces need time to initialize and/or do not report correct status.
# By default, DHCPv6 waits until the link-local address (fe80::) is available
# and then ~1 second as specified by RFC3315.
# This setting allows override to use a non-standsrd initial delay.
#
DHCLIENT6_SLEEP="0"

## Type:	integer
## Default:	15
#
# The DHCPv6 client will try to get a lease for DHCLIENT6_WAIT_AT_BOOT seconds,
# then inform ifup waiting for it, that it continues in background.
# When you increase this time, increase also the WAIT_FOR_INTERFACES variable
# e.g. to a value twice as high as the time specified here.
#
DHCLIENT6_WAIT_AT_BOOT="15"

## Type:	integer
## Default:	"0"
#
# The dhcpv6 client will stop processing / fail after this time when it does
# not get a reply from the dhcp server. Before you set this variable, take a
# look at DHCLIENT6_WAIT_AT_BOOT allowing to continue in background instead.
#
DHCLIENT6_TIMEOUT="0"

DHCLIENT_SET_HOSTNAME="yes"

## Type:	string
## Default:	AUTO
#
# Specifies the hostname option field when DHCPv4 client sends messages.
# Some DHCP servers will update nameserver entries (dynamic DNS) to it.
