builddbm ‐ build a DBM version of Radius users database

builddbm [‐d config_dir] [input_file]

     builddbm ‐h

Builddbm converts the plaintext Radius users database into
DBM files. Some versions of Radius daemon have used this to
speed up the access to the users database.

     However in this implementation of Radius daemon things
go the other way around. The server reads entire plaintext
database, converts it into internal form and stores into
hash table which provides for fast access. Actually, using
DBM version of the users database slows down the access
unless the machine which runs Radius daemon is short of
address space for the daemon to store the users database

     Optionally, Radius daemon can use both plaintext and
DBM databases, in which case it first looks up the user in
the former, and if not found, continues search in the

When used without arguments, builddbm utility attempts to
convert file /usr/local/etc/raddb/users into
/usr/local/etc/raddb/users.db or
/usr/local/etc/raddb/users.dir pair depending on the version
of DBM library used.

     If used with one argument, the argument is taken as the
name of the plaintext database file to operate upon.

‐d   Specifies alternate directory for the Radius users
     database files. This defaults to /usr/local/etc/raddb.

     Default plaintext database.

     Default output file.
