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.

       makedbm - create or dump a ypserv database file

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

       -b
           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.

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

       -l
           Convert the keys of the given map to lower case.

       -iYP_INPUT_NAME
           Create a special entry with the key YP_INPUT_NAME.

       -mYP_MASTER_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.

       -oYP_OUTPUT_NAME
           Create a special entry with the key YP_OUTPUT_NAME.

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

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

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

       --no-limit-check
           Don't check for NIS key and data limit.
