YPALIASES(5)

NAME
ypaliases - NIS aliases for sendmail

SYNOPSIS
/etc/ypaliases

AVAILABILITY

Available only on Sun 386i systems running a SunOS 4.0.x release or earlier. Not a SunOS 4.1 release feature.

DESCRIPTION

Create the Network Information Service (NIS) aliases map with this text file. The /etc/ypaliases file has the same format as the /etc/aliases file described in aliases(5).

The text file for the NIS aliases map is stored in the /etc/aliases file on the NIS master of an NIS domain. Other systems in a domain (besides the NIS master) can also have a local /etc/aliases file. The local file is accessed first by programs such as sendmail(8), and if it contains a line beginning with the character `+', the NIS map will be accessed.

The local /etc/aliases file can specify resources that are not available on a network-wide basis. This implies that the NIS master cannot use the local /etc/aliases file to specify aliases that are to be known only to the local system. Sun386i systems allow the /etc/aliases file on the NIS master to be used locally, creating the NIS aliases map with the /etc/ypaliases text file.
