NAME
netid - netname database
SYNOPSIS
/etc/netidDESCRIPTION
The
netid file is a local source of information on mappings between
netnames (see
secure_rpc(3NSL)) and user ids or hostnames in the local
domain. The
netid file can be used in conjunction with, or instead of, a
network nameservice. The
publickey entry in the
nsswitch.conf (see
nsswitch.conf(5)) file determines which of these sources will be queried
by the system to translate netnames to local user ids or hostnames.
Each entry in the
netid file is a single line of the form:
netname uid:gid, gid, gid... or
netname 0:hostname The first entry associates a local user id with a netname. The second
entry associates a hostname with a netname.
The
netid file field descriptions are as follows:
netname The operating system independent network name for the user or
host.
netname has one of two formats. The format used to
specify a host is of the form:
unix.hostname@domain where
hostname is the name of the host and
domain is the
network domain name.
The format used to specify a user id is of the form:
unix.uid@domain where
uid is the numerical id of the user and
domain is the
network domain name.
uid The numerical id of the user (see
passwd(5)). When specifying
a host name,
uid is always zero.
group The numerical id of the group the user belongs to (see
group(5)). Several groups, separated by commas, may be
listed for a single
uid.
hostname The local hostname (see
hosts(5)).
Blank lines are ignored. Any part of a line to the right of a `
#' symbol
is treated as a comment.
