4 Univention Directory Manager 70 Umlauts and special characters are not permitted. The full stop is used as a separating mark between the individual components of a FQDN and must therefore not appear as part of the computer name. Computer names must begin with a letter. Microsoft Windows accepts computer names with a maximum of 15 characters, so as a rule computer names should be limited to 15 characters if there is any chance that Microsoft Windows will be used. ’IP’ tab IP address Fixed IP addresses for the host can be given here. If a network was selected on the General tab, the IP address assigned to the host from the network will be shown here automatically. The IP addresses shown here can still be changed at another time. A thin client needs a fixed IP address under all circumstances. Attention: An IP address entered here (and in the LDAP directory) can be now be transmitted to the host via DHCP. If no DHCP server is being used, the IP address can also be transferred to the host locally. Attention: If the IP addresses entered for a host are changed without the DNS zones being changed, they are automatically changed in the computer object and — where they exist — in the DNS entries of the forward and reverse lookup zones. If the IP address of the host was entered at other places as well, these entries must be changed manually! For example, if the IP address was given in a DHCP boot policy instead of the name of the boot server, this IP address will need to be changed manually by editing the policy. ’DNS’ tab This tab allows selection of the forward and reverse lookup zones in which the host is entered and specification of a DNS alias. A fixed IP address is required for these entries, which must be entered on the IP tab so that the DNS entries can be created automatically. No entries are created so long as no zones have been selected. In order for a thin client to function correctly it requires a DNS entry (Host record in the forward lookup zone). More detailed information on the topic of DNS can be found in the Chapter 4.5.9. Forward zone for DNS entry A forward lookup zone for the host can be selected here. All the forward lookup zones entered in the domain and their subcontainers are available for selection. In addition it is also necessary to select one of the host’s IP addresses with which the host should be included in the forward lookup zone.
Reverse zone for DNS entry 4.5 Univention Directory Manager modules A reverse lookup zone for the host can be selected here. All the reverse lookup zones entered in the domain and their subcontainers are available for selection. In addition it is also necessary to select one of the host’s IP addresses corresponding to the reverse lookup zones with which the host should be mounted in the reverse lookup zone. Alias If a zone entry for forward mapping has been set up for the host in the Forward zone for DNS entry field, the additional alias entries via which the host can be reached can be configured here. ’DHCP’ tab More detailed information on the topic of DHCP can be found in the Chapter 4.5.10. DHCP In order for a host to receive an IP address from a DHCP service an entry must consist of DHCP service, MAC address and IP address. The DHCP service which should assign the host an IP address should be selected in the first selection field. The DHCP services registered in the domain are available for selection. Please note that the selected DHCP server must be responsible for the physical network. The MAC address of the network card with which the host requests an IP address from the DHCP service must be entered in the second selection field. The MAC address of the host’s network card required for this must firstly be entered on the General tab. The IP address which the DHCP service assigns to the host should be selected in the third selection field. If a network is selected on the General tab an appropriate entry for the network will be added automatically. This can be adapted subsequently. A DHCP entry is necessary for a thin client under all circumstances. ’Account’ tab’ This tab is only found on host types which join the UCS domain, e.g., domain controller, managed clients, Mac OS X clients, . . . Password Hosts which are member of the UCS domain require a password to be able to read and change their own data in the LDAP directory. The host creates a password automatically when joining the domain and makes a note of this in the /etc/machine.secret file and in the LDAP directory. Any 71
