SYNOPSIS

       kpropd  [  -r realm ] [ -f slave_dumpfile ] [ -F principal_database ] [
       -p kdb5_util_prog ] [ -d ] [ -S ] [ -P port ]

DESCRIPTION

       kpropd is the server which accepts connections from the  kprop(8)  pro-
       gram.   kpropd accepts the dumped KDC database and places it in a file,
       and then runs kdb5_util(8) to load the dumped database into the  active
       database which is used by krb5kdc(8).  Thus, the master Kerberos server
       can use kprop(8) to propagate its database to the slave slavers.   Upon
       a  successful  download  of  the  KDC database file, the slave Kerberos
       server will have an up-to-date KDC database.

       Normally, kpropd is invoked out of inetd(8).  This is done by adding  a
       line to the inetd.conf file which looks like this:

       kprop     stream    tcp  nowait    root /usr/local/sbin/kpropd   kpropd

       However, kpropd can also run as a standalone deamon, if the  -S  option
       is turned on.  This is done for debugging purposes, or if for some rea-
       son the system administrator  just  doesn't  want  to  run  it  out  of
       inetd(8).

OPTIONS

       -r realm
              specifies  the  realm of the master server; by default the realm
              returned by krb5_default_local_realm(3) is used.

       -f file
              specifies the filename where the dumped principal database  file
              is  to  be  stored;  by  default  the  dumped  database  file is
              KPROPD_DEFAULT_FILE  (normally  /usr/local/var/krb5kdc/from_mas-
              ter).

       -p     allows the user to specify the pathname to the kdb5_util(8) pro-
              gram; by default the pathname used  is  KPROPD_DEFAULT_KDB5_UTIL
              (normally /usr/local/sbin/kdb5_util).

       -S     turn  on  standalone  mode.   Normally, kpropd is invoked out of
              inetd(8) so it expects a network connection to be passed  to  it
              from  inetd (8).  If the -S option is specified, kpropd will put
              itself into the background, and  wait  for  connections  to  the
              KPROP_SERVICE port (normally krb5_prop).

       -d     turn on debug mode.  In this mode, if the -S option is selected,
              kpropd will not detach itself from the current job  and  run  in
              the  background.   Instead,  it  will  run in the foreground and
              print out debugging messages during the database propagation.

       -P     allow for an alternate port number for kpropd to listen on. This
              is only useful if the program is run in standalone mode.
