4 <strong>Univention</strong> Directory Manager 116 DDNS update style There are currently two DNS update patterns available: the ad-hoc DNS update mode (ad-hoc) and the interim DHCP-DNS interaction draft update mode (interim). The ad-hoc mode is now outdated and should no longer be used. Attention: This setting is evaluated once by the DHCP service when importing the configuration. It is thus not possible to stipulate the update style for each client individually. DDNS Forward Updates If the True value is selected, the DHCP service updates the DNS computer entry (A record) if a DHCP client requests or renews a lease. No update is performed if the setting is set to false. This input only applies when DNS updates are activated and the DDNS update style is set to interim. DDNS forward updates are performed as standard. Update static leases If the True value is selected, the DHCP service performs DNS updates, even when they are assigned a static IP address. No update is performed if the setting is set to false. This input only applies when DNS updates are activated and the DDNS Update Stil is set to interim. Client updates When the Allow value is selected, the DHCP service notes the intention of the DHCP client to update its own DNS computer entry (A record). This input only applies when DNS updates are activated and the DDNS Update Stil is set to interim. ’[DHCP lease time]’ time Default lease time If the client does not ask for a specified lease time it will be assigned the standard lease time. If this input field is left empty, the DHCP server’s default value is used. That is 43200 seconds (12 hours). Maximum lease time The maximum lease time specifies the longest period of time for which a lease can be granted. If this input field is left empty, the DHCP server’s default value is used. That is 86400 seconds (24 hours). Minimum lease time The minimum lease time specifies the shortest time for which a lease can be valid. If this input field is left empty, the DHCP server’s default value is used. That is one second.
’[DHCP NetBIOS]’ tab NetBIOS name servers 4.5 <strong>Univention</strong> Directory Manager modules Also called NBNS or WINS servers. The names or IP addresses of the NetBIOS name servers are to be entered here. It must be verified that the DHCP server can resolve these names in IP addresses. The servers entered are contacted by the client in the order in which they stand in the selection list. NetBIOS scope The NetBIOS over TCP/IP scope for the client according to the specification in RFC1001 and RFC1002. Attention: Attention must be paid to uppercase and lowercase when entering the NetBIOS scope. Further information on the character set to use can be found in RFC1035. NetBIOS Node Type Dieses Auswahlfeld legt den Node Type eines Clients fest. Mögliche Werte sind: • 1 B node (Broadcast: no WINS) • 2 P node (Peer: only WINS) • 4 M node (Mixed: first Broadcast, then WINS) • 8 H node (Hybrid: first WINS, then Broadcast) ’[NFS mounts]’ tab This policy can be used to configure NFS shares mounted on the server or client. There is a NFS Share for selection, which is mounted in the file path specified under Mount point. ’[DHCP routing]’ tab Routers The names or IP addresses of the routers are to be entered here. It must be verified that the DHCP server can resolve these names in IP addresses. The routers are contacted by the client in the order in which they stand in the selection list. Attention: Routers usually have several network interfaces each with its own IP address. If the name of the router is entered instead of the IP address, it must be verified that the name definitely points to the required network interface on the router! 117
