YPALIASES(5) — FILE FORMATS

NAME

ypaliases - aliases for sendmail(8)

SYNOPSIS

/etc/ypaliases

AVAILABILITY

Sun386i systems only.

DESCRIPTION

This is the text file used to create the YP aliases map on the Sun386i. It has the same format as the /etc/aliases file described in aliases(5).

The text file for the YP aliases map is stored in the /etc/aliases file on the YP master of a YP domain. Other systems in a domain (besides the YP master) can also have a local /etc/aliases file. The local file is accessed first by programs such as sendmail(8), then by the YP aliases file. The local /etc/aliases file on a machine can be used to specify resources that are not available on a network-wide basis.

This strategy implies that the YP master cannot use the local /etc/aliases file to specify aliases that are to be known only to the local system. This is because the local /etc/aliases file on the YP master is the actual text file used to create the YP aliases map. The Sun386i solves this by allowing the /etc/aliases file on the YP master to be used locally, and using /etc/ypaliases as the text file used for creating the YP aliases map. This also allows re-creation of /etc/ypaliases on each slave server so each can more easily become a master.
