makedbm - 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
/usr/lib/yp/makedbm -u dbname
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.
-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.
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.
-r Handle ‘#’ as comment sign and remove the comment.
-s Secure map. Accept connections from secure NIS networks only
Dump a ypserv database file. Prints out the file in text format,
one entry per line, with a single space separating keys from
Don’t check for NIS key and data limit.
