NAME
pwgrd — Password and Group Hashing and Caching daemon.
SYNOPSIS
/usr/sbin/pwgrd
[-d]
[-l
logfile]
DESCRIPTION
pwgrd
provides accelerated lookup of password and group information
for libc routines like
getpwuid
and
getgrname.
pwgrd
implements per request type caches and hashtables as appropriate.
When the corresponding routine in libc is called,
a request is issued to
pwgrd
via a Unix domain socket connection.
pwgrd
determines whether it can satisfy the request,
returning the appropriate results to the requesting process.
Options
pwgrd
recognizes the following options and command-line arguments:
- -d
Debug mode. Do not become a daemon.
Issue additional diagnostic messages.
Instead of logging message via
syslog,
issue messages to stderr.
- -l
logfile
Logfile. In addition to logging via
syslog,
pwgrd
will write log messages to
logfile.
pwgrd
modifies its behavior depending on whether or not the local machine
is using some form of
NIS
for password or group information.
When
NIS
or
NIS+
is being used,
the hashtables corresponding to that service are not
generated or consulted.
Therefore only caching is provided for those requests.
FILES
- /etc/rc.config.d/pwgr
Start up configuration variable.
Set
PWGR
to
1
if you want
pwgrd
to start on reboot.
- /var/spool/pwgr/*
Hash files, status file and daemon Unix domain socket.
- /var/spool/sockets/pwgr/*
Client Unix domain sockets.
