PNP.SYSNAMES(5) — FILE FORMATS

NAME

pnp.sysnames − file used to allocate system names

SYNOPSIS

/etc/pnp.sysnames

AVAILABILITY

Sun386i systems only.

DESCRIPTION

The /etc/pnp.sysnames file contains system names that may be allocated on demand, typically as part of Automatic System Installation.

The system names should be legal system names, one per line. Legal names under SunOS 4.0 are up to 31 characters long, and consist of lowercase alphanumeric characters, dashes, and underscores. The first character must be alphabetic, and the last character should be alphanumeric. Blank lines are allowed in the file, but comments are not.

When a system name needs to be allocated, the first unused system name is taken from /etc/pnp.sysnames. If all the system names there in use, unused names are allocated from the list system-1, system-2, ...; the default prefix “system” may be changed in the /var/yp/updaters makefile. A system name is “used” if there is already a matching entry in the YP hosts.byname map, the ethers.byname map, or there is a netgroup with that name. Names are allocated to correspond to a given Ethernet address.

One way to allocate a system name is to issue a ypupdate(3) call to update the ethers.byaddr map. The key is the Ethernet address (or general IEEE 802.2 48 bit address, used also with FDDI and Token Ring standards) of the system whose name is being allocated. The data is a line formatted according to the format specified in ethers(5). A name is allocated if the name passed is “∗” (a single asterisk). Updating this YP map via ypupdate(3) is a privileged operation, and may be performed only by users in the networks group (with group ID 12), or boot servers (listed in the ypservers YP map).
