       rpc.dracd - Dynamic Relay Authorization Control server


       rpc.dracd [-i ] [ -e expire ] [ dbfile ]



       rpc.dracd  is  the  Dynamic  Relay  Authorization Control server.  It uses the Berkeley db
       package to maintain a relay authorization map for sendmail, by default /etc/drac/dracd.db.
       POP  and  IMAP  mail  servers  make an RPC call to add an entry to the authorization cache
       after they have authenticated each user.  The daemon, rpc.dracd, adds or  updates  entries
       in  the  cache,  and  periodically  expires  old  entries.   Only trusted mail servers are
       permitted to communicate with rpc.dracd, as controlled by /etc/drac/dracd.allow.  If  this
       file does not exist, all local IP addresses are permitted.

   Allow File Format
       The Allow File file consists of entries of the form:

              netmask netaddr

       where both netmask and netaddr must be dotted quads.


       -i             Initialize the database on startup.

       -e expire      Set  the  expire  time  limit.  expire is the number of minutes the entries
                      will remain in the database.  It defaults to 30 minutes.

       dbfile         Use a different database file name.


       /etc/drac/dracd.db            default database file
       /etc/drac/dracd.allow         default allow file.


       This rpc.dracd version is protected by the tcp_wrapper  library.  You  have  to  give  the
       clients  access  to  rpc.dracd if they should be allowed to use it. To allow connects from
       clients of the domain you could use the following line in /etc/hosts.allow:


       You have to use the daemon name dracd for the daemon  name  (even  if  the  binary  has  a
       different name).

       For  further  information  please  have  a  look at the tcpd(8) and hosts_access(5) manual




       The following signals have the specified effect when sent to the server process using  the
       kill(1) command.

       SIGTERM             closes the database and terminates the server.
