- ## Path: Network/DHCP/DHCP client
- ## Description: DHCP configuration tweaking
- #
- # 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 these options are used only by dhcpcd, not by the ISC dhclient (which
- # uses a config file).
- #
- # Most of the options can be overridden by setting them in the ifcfg-* files,
- # too.
-
- ## Type: string
- ## Default: ""
- ## ServiceRestart: network
- #
- # Which DHCP client should be used?
- # If empty, dhcpcd is tried, then dhclient
- # Other possible values:
- # dhcpcd (DHCP client daemon)
- # dhclient (ISC dhclient)
- DHCLIENT_BIN=""
-
- ## Type: yesno
- ## Default: no
- #
- # Start in debug mode? (yes|no)
- # (debug info will be logged to /var/log/messages for dhcpcd, or to
- # /var/log/dhclient-script for ISC dhclient)
- #
- DHCLIENT_DEBUG="no"
-
- ## Type: yesno
- ## Default: no
- #
- # Should the DHCP 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="no"
-
- ## Type: yesno
- ## Default: yes
- #
- # Should the DHCP client modify /etc/resolv.conf at all?
- # If not, set this to "no". (The default is "yes")
- #
- # resolv.conf will also stay untouched when MODIFY_RESOLV_CONF_DYNAMICALLY
- # in /etc/sysconfig/network/config is set to "no".
- #
- DHCLIENT_MODIFY_RESOLV_CONF="yes"
-
- ## Type: yesno
- ## Default: yes
- #
- # Should the DHCP client set a default route (default Gateway) (yes|no)
- #
- # When multiple copies of dhcpcd run, it would make sense that only one
- # of them does it.
- #
- DHCLIENT_SET_DEFAULT_ROUTE="yes"
-
- ## Type: yesno
- ## Default: no
- #
- # Should the DHCP client modify the NTP configuration? (yes|no)
- #
- # If set to yes, /etc/ntp.conf is rewritten (and restored upon exit).
- # If you don't want this, set this variable to "no". (The default is "no")
- #
- DHCLIENT_MODIFY_NTP_CONF="no"
-
- ## Type: yesno
- ## Default: no
- #
- # Should the DHCP client modify the NIS configuration? (yes|no)
- #
- # If set to yes, /etc/yp.conf is rewritten (and restored upon exit).
- # If you don't want this, set this variable to "no". (The default is "no")
- #
- DHCLIENT_MODIFY_NIS_CONF="yes"
-
- ## Type: yesno
- ## Default: yes
- #
- # Should the DHCP client set the NIS domainname? (yes|no)

- #
- DHCLIENT_SET_DOMAINNAME="yes"
-
- ## Type: yesno
- ## Default: yes

- # When writing a new /etc/resolv.conf, should the DHCP client take an
- # existing searchlist and add it to the one derived from the DHCP server?
- #
- DHCLIENT_KEEP_SEARCHLIST="yes"
-
- ## Type: integer
- ## Default: ""
- #
- # Lease time to request ( -l option)

- # Specifies (in seconds) the lease that is suggested to the server.

- # set this to a lower value.
- #
- DHCLIENT_LEASE_TIME=""
-
- ## Type: integer
- ## Default: 999999
- #
- # (only dhcpcd does use this setting)
- #
- # You can set the timeout (dhcpcd will terminate after this time when it
- # does not get a reply from the server).
- #
- # The default timeout of dhcpcd is 60 seconds. However, we'll set it to a
- # much longer time. dhcpcd will then run as a daemon in the background and
- # broadcast a DHCPDISCOVER once in a while, trying to get a lease.

- ## Type: integer
- ## Default: ""

- # (only dhcpcd does use this setting)
- #
- # INIT-REBOOT timeout ( -z option)

- # This timeout is specifically to control how long dhcpcd tries to reacquire

- # Default: 10
- #
- DHCLIENT_REBOOT_TIMEOUT=""
-
- ## Type: string
- ## Default: AUTO
- #
- # specify a hostname to send ( -h option)
- #
- # specifies a string used for the hostname option field when dhcpcd sends DHCP
- # messages. Some DHCP servers will update nameserver entries (dynamic DNS).
- # 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.
- #
- # By default the current hostname is sent ("AUTO"), if one is defined in
- # /etc/HOSTNAME.
- # Use this variable to override this with another hostname, or leave empty
- # to not send a hostname.
- #
- DHCLIENT_HOSTNAME_OPTION="AUTO"
-
- ## Type: string
- ## Default: ""
- #
- # specify a client ID ( -I option)
- #
- # Specifies a client identifier string. By default the hardware address of the
- # network interface is sent as client identifier string, if none is specified
- # here.
- #
- # Note that dhcpcd will prepend a zero to what it sends to the server. In the
- # server configuration, you need to write the following to match on it:
- # option dhcp-client-identifier "\0foo";
- #
- DHCLIENT_CLIENT_ID=""
-
- ## Type: string("dhcpcd dhclient")
- ## Default: ""
- #
- # specify a vendor class ID ( -i option)

- # Specifies the vendor class identifier string. dhcpcd uses the default vendor
- # class identifier string (system name, system release, and machine type) if it
- # is not specified.
- #
- DHCLIENT_VENDOR_CLASS_ID=""
-
- ## 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: string
- ## Default: ""
- #
- # Run this script when the interface is brought up, down, or the IP address
- # changes ( -c option)
- #
- # Per default, /etc/sysconfig/network/scripts/dhcpcd-hook is run.
- # To disable this functionality altogether you can enter "/bin/true" here.
- #
- DHCLIENT_SCRIPT_EXE=""
-
- ## Type: yesno
- ## Default yes

- # Force dhcpcd to calculate UDP checksum on received packets. (yes|no)

- # Some interfaces need time to initialize. Add the latency time in seconds
- # so these can be handled properly. Should probably set per interface rather than here.
- #
- DHCLIENT_SLEEP="0"
-
- ## Type: integer
- ## Default: 5
- #
- # When the DHCP client is started at boot time, the boot process will stop

- ## Type: yesno
- ## Default: yes
- ## ServiceRestart: yast2
- #
- # This option is read by YaST during network configuration.
- #
- # If set, then the hostname is added to /etc/hosts with IP address
- # 127.0.0.2. This allows the hostname to be resolved (and thus, the host
- # to be reached), if the real network is not reachable.

- # If unset, YaST will not touch /etc/hosts.
