YP_MASTER_NAME ] inputfile 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. |
?i YP_INPUT_NAME |
Create a special entry with the key YP_INPUT_NAME. |
?m YP_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. |
?o YP_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). |
?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. |
??no-limit-check |
Don’t check for NIS key and data limit. |
ypserv(8) |
