Novell's dhcp 2.0 server supports automatic bootp allocation. It stores its mapping table to disk and the software is free. Quite a few of our customers use this feature. Kester >>> Justin Clark - Integralis UK <email@example.com> 04/11/97 04:07AM >>> We are planning to provide BOOTP clients (those that do not have an upgrade path to DHCP) with addresses from our DHCP servers pool - providing we write support for this in our server. We accept that Lease times cannot be supported and that the BOOTP client will request an address on every bootup (i.e have no past knowledge of address allocation). Only problem is that if the dhcp server does not have any past knowledge of address allocation then we will quickly run out of addresses because each reboot requests a new address! So the plan is to *build* a 'static' table of MAC/IP pairs within our server based on the first address allocations for each system..... The idea is that when a bootp client reboots and requests 'another' address, the dhcp server should browse through it's cache (memory or from disk) of previously-allocated addresses and realise that the bootp client needs the address that the server allocated previously. I have a couple of questions to pose to the group: 1> Any fundamental flaws in this? 2> Can the static/dynamic table be in memory cache or should it be committed to disk? 4> Are there any commercial or shareware vendors providing such a capability? i.e a large corporate doesn't need to build a MAC/IP address pair table for each client - the server dynamically builds the table based on first allocations?
