Loading Data From an NIS Map

You can transfer information from an NIS map in two different ways; either by specifying the NIS domain or by specifying the actual NIS map. If you specify the domain, NIS+ will figure out which map file in /var/yp/nisdomain to use as the source, based on the table-type. Note that /var/yp/nisdomain must be local files.

To transfer by specifying the NIS domain, use the -y (lowercase) option and provide the NIS domain in addition to the NIS+ table type.

Table replacement

nisaddent -y nisdomain table-type

Table append

nisaddent -a -y nisdomain table-type

Table merge

nisaddent -m -y nisdomain table-type

By default, nisaddent replaces the contents of the NIS+ table with the contents of the NIS map. Use the -a and -m options to append or merge. Here is an example that loads the NIS+ passwd table from its corresponding NIS map (passwd.byname) in the old-doc domain:

rootmaster# /usr/lib/nis/nisaddent -y old-doc passwd

This example does the same thing, but for the sales.doc.com. domain instead of the local domain, doc.com.

rootmaster# /usr/lib/nis/nisaddent -y old-doc passwd sales.doc.com.

If the NIS+ table is an automounter table or a nonstandard table, add the -t option and the complete name of the NIS table, just as you would if the source were a file.

rootmaster# nisaddent -y old-doc \
  -t auto_home.org_dir.doc.com. key-value
rootmaster# nisaddent -y old-doc \
  -t auto_home.org_dir.doc.com. key-value sales.doc.com.

If instead of using the map files for a domain, you prefer to specify a particular NIS map, use the -Y (uppercase) option and specify the map name.

rootmaster# nisaddent -Y hosts.byname hosts
rootmaster# nisaddent -Y hosts.byname hosts sales.doc.com.

If the NIS map is an automounter map or a non standard map, combine the -Y option with the -t option:

rootmaster# nisaddent -Y auto_home 
 -t auto_home.org_dir.doc.com. key-value
rootmaster# nisaddent -Y auto_home 
 -t auto_home.org_dir.doc.com. key-value sales.doc.com.
