.TH BUILDDBM 8 "09 Nov 2001" "" "Cistron Radius Daemon"
.SH NAME
builddbm -- build DBM file from RADIUS users file.
.SH SYNOPSIS
.B builddbm
.SH DESCRIPTION
This utility is used to build a DBM file (in DBM, NDBM or DB format) from
the radius \fIusers\fP file to save memory and increase speed.
.PP
Usage of this utility is only encouraged if
you have more than, say, 2000 entries in the \fIusers\fP file. Normally,
\fBradiusd\fP reads the \fIusers\fP file into memory at startup. With
very large files this may cost too many resources and it may then
be wiser to use a DBM file to save memory and speed up the server.
.PP
The file format used is so that all semantics of the normal users
file are preserved, in particular ordering, multiple entries
with duplicate keys, and Fall-Through.
.PP
Note that normally the radius server resolves hostnames into IP
addresses just once when it starts up, but with a DBM users file
it is done for each request. It's probably a good idea to use
IP addresses directly instead of hostnames with attributes like
Framed-IP-Address.
