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 con-

nection.

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

pwgrd to start on reboot.

/var/spool/pwgr/*

/var/spool/sockets/pwgr/*

Client Unix domain sockets.
