makedbm - Man Page

create or dump a ypserv database file


/usr/lib/yp/makedbm [-a | -r] [-b] [-c] [-s] [-l] [-i YP_INPUT_NAME] [-o YP_OUTPUT_NAME] [-m YP_MASTER_NAME] inputfile dbname

/usr/lib/yp/makedbm -u dbname

/usr/lib/yp/makedbm -c

/usr/lib/yp/makedbm --version


makedbm takes the inputfile and converts it to a ypserv database file. In the moment, GDBM is used as database. Each line of the input file is converted to a single record. All characters up to the first TAB or SPACE are the key, and the rest of the line is the data. makedbm does not treat `#' as a special character.



Special support for mail aliases. We couldn't use sendmail for it, since sendmail uses db, but ypserv gdbm as database format.


Insert the YP_INTERDOMAIN into the output. This key causes ypserv(8) to use DNS for host name and address lookups for hosts not found in the maps.


send a YPPROC_CLEAR to the local ypserv(8). This causes ypserv to invalidate all cached entries.


Convert the keys of the given map to lower case.


Create a special entry with the key YP_INPUT_NAME.


Create a special entry with the key YP_MASTER_NAME. If no master host name is specified, YP_MASTER_NAME will be set to the local host name.


Create a special entry with the key YP_OUTPUT_NAME.


Handle `#' as comment sign and remove the comment.


Secure map. Accept connections from secure NIS networks only (reserved ports).

-u dbname

Dump a ypserv database file. Prints out the file in text format, one entry per line, with a single space separating keys from values.


Don't check for NIS key and data limit.
