NAME

updaters - configuration file for YP updating

SYNOPSIS

/var/yp/updaters

DESCRIPTION

The file /var/yp/updaters is a makefile (see make(1)) which is used for updating YP databases. Databases can only be updated in a secure network, that is, one that has a publickey(4) database. Each entry in the file is a make target for a particular YP database. For example, if there is a YP database named publickey.byname that can be updated, there should be a make target named publickey.byname in the updaters file with the command to update the file. The information necessary to make the update is passed to the update command through standard input. The information passed is described below (all items are followed by a NEWLINE, except for the actual bytes of key and actual bytes of date).

• Network name of client wishing to make the update (a string)

• Kind of update (an integer)

• Number of bytes in key (an integer)

• Actual bytes of key

• Number of bytes in data (an integer)

     •  Actual bytes of data
After getting this information through standard  input,  the
command  to  update  the  particular  database should decide
whether the user is allowed to make the change.  If not,  it
should  exit  with  the status YPERR_ACCESS.  If the user is
allowed to make the change,  the  command  should  make  the
change  and  exit  with  a status of zero.  If there are any
errors that may prevent the updater from making the  change,
it should exit with the status that matches a valid YP error
code described in <rpcsvc/ypclnt.h>.
