NAME

utmpd– utmp and utmpx monitoring daemon

SYNOPSIS

utmpd [-debug]

DESCRIPTION

The utmpd daemon monitors /var/adm/utmp and /var/adm/utmpx files. See utmp(4) and utmpx(4).

utmpd receives requests from pututline(3C) and pututxline(3C) by way of a named pipe. It maintains a table of processes and uses poll(2) on /proc files to detect process termination. When utmpd detects that a process has terminated, it checks that the process has removed its utmp entry from /var/adm/utmp and /var/adm/utmpx. If the process' utmp entry has not been removed, utmpd removes the entry. By periodically scanning the /var/adm/utmp and /var/adm/utmpx files, utmpd also monitors processes that are not in its table.
