namepool(4) Kernel Interfaces Manual namepool(4) NAME namepool - DHCP server database DESCRIPTION namepool tells joind, the DHCP server what names are available for dy- namic assignment to clients of the DHCP protocol. It contains, for each DHCP server and domain name (NIS or DNS), a collection of names avail- able for allocation to DHCP clients within those domains. One name plays a distinguished role - it is used as a prefix when the pool has been exhausted. Names are generated from the prefix by appending a number, 1,2.., and a trailing 'd'. The namepool file is re-read when- ever joind starts up. Names within it must not be allocated to hosts which are not DHCP clients, and if the administration of a domain is shared between several DHCP servers, the namepools that each has must be disjoint. Names may freely be added and removed from namepool. If a name is removed from the file it will still remain bound to the client to which it was allocated, but if no such binding is in effect the name will be excised from the server's pool the next time the server starts up. Once a name has been dynamically bound to a host it will never be re-used even if that host subsequently acquires a new name, but there is no need to remove it from namepool. FORMAT Blank lines and lines beginning with "#" are ignored. A new entry must begin in column one and looks as follows: do- main server or do- main server name_pre- fix domain is the domain in which the names which follow are assigned. server is the name or IP address of the server in charge of allocating these names to clients. prefix is the prefix which will be used when the pool is exhausted. Succeeding lines contain one or more names for domain and which are to be allocated by server. These succeeding lines must all have at least one character of whitespace starting the line. There may be an unlim- ited number of them. FILES /etc/join/namepool RELATED INFORMATION joind(8), join.ipaddresses(4). delim off namepool(4)
