System Administration Guide: Naming and Directory Services (NIS+)

Changing the Time-to-Live of an NIS+ Object

To change the time-to-live of an object, type the nischttl command with the time-to-live value and the object-name. You can add the -L command to extend the change to linked objects.

nischttl -L time-to-live object-name

You can specify the time-to-live in seconds by typing the number of seconds. Or you can specify a combination of days, hours, minutes, and seconds by using the suffixes s, m, h, and d to indicate the number of seconds, minutes, days, and hours. For example:

client% nischttl 86400
client% nischttl 24h
client% nischttl 2d1h1m1s

The first two commands change the time-to-live of the directory to 86,400 seconds, or 24 hours. The third command changes the time-to-live of all the entries in a hosts table to 2 days, 1 hour, 1 minute, and 1 second.
