Creating new maps

To create a new NIS map:

1. On the master server, enter:
   
   cd /etc/yp

2. Create an ASCII file containing the contents of the desired map. The ASCII file format must consist of key-value pairs with space separating the key from its value as in:
   
   key1 value1
   key2 value2
   key3 value3

3. Create the NIS map for this file using the makedbm command. For an ASCII file called mymap.asc:
   
   ./makedbm mymap.asc domain_name/mymap

   The result is a map called /etc/yp/domain_name/mymap.

4. Add the new map name to the YP_MAP_X_LATE file on all servers in the NIS domain.

5. Create a new map2ascii routine and copy it to all servers on which you wish the new map to be converted to ASCII format after it is propagated. A map2ascii routine is required on any copy-only servers.

6. Propagate the map to slave servers in the NIS domain using the yppush command. For the example map mymap, enter:
   
   yppush mymap
