The Question is: DHCP server Option use_macaddr_as_id fails. I use the TCPIP DHCP server (UXC V5.3 - ECO 1) in a VMS cluster environment to configure static IP-Adresses for about 600 DHCP clients. My Problem is, that PCs use different DHCP-IDs when they boot with DOS, Windows and Linux. I want to ignore the format therefore and assign the IP address only according to the mac adress. To do this, I have to use the server.pcy option "use_macaddr_as_id". But with this setting the DHCP service fails to start writing following log entry: "The policy file 'server.pcy' is (potentially) incompatible with the existing database. ..." - Even after I deleted all database files and there is no incompatible information in it (because there is no information at all). This failure does not depend on a special configuration and can be reproduced easily. I studied all available documentation and am shure that all was configured correctly. Is it a known bug and eventually fixed in a later release, or is it my mistake ? This problem is very urgent because I fear it would be impossible to find another solution that allows to manage this amount of addresses with comparable efficiency - I wrote some DCL scripts that generate all data files for DNS and DHCP and update these services automatically. The Answer is : Please first look at TCP/IP Services V5.4 and ECO, or (at least) the application of the current ECO for V5.3. (As of this writing, ECO 4 is current, and ECO 4 does include updates for various problems found within DHCP.) The OpenVMS Wizard is aware of one previous report that may be related to this, though additional details would be required to establish that similarity with any certainty. As this is an urgent request, please contact the support center directly as details of the configuration files and the settings will be required.
