# /etc/login.defs - Configuration control definitions for the login package.
#
# Three items must be defined:  MAIL_DIR, ENV_SUPATH, and ENV_PATH.
# If unspecified, some arbitrary (and possibly incorrect) value will
# be assumed.  All other items are optional - if not specified then
# the described action or option will be inhibited.
#
# Comment lines (lines beginning with "#") and blank lines are ignored.
#
# Modified for Linux.  --marekm

#
# Delay in seconds before being allowed another attempt after a login failure

#
# Enable "syslog" logging of su activity - in addition to sulog file logging.
# SYSLOG_SG_ENAB does the same for newgrp and sg.
#
SYSLOG_SU_ENAB		yes
SYSLOG_SG_ENAB		yes

#
# If defined, either full pathname of a file containing device names or
# a ":" delimited list of device names.  Root logins will be allowed only
# upon these devices.
#

#
# If defined, file which maps tty line to TERM environment parameter.
# Each line of the file is in a format something like "vt100  tty01".
#
#TTYTYPE_FILE	/etc/ttytype

#
# If defined, the command name to display when running "su -".  For
# example, if this is defined as "su" then a "ps" will display the

#
SU_NAME		su

#

#   Directory where mailboxes reside, _or_ name of file, relative to the

#   QMAIL_DIR is for Qmail
#
#QMAIL_DIR	Maildir
MAIL_DIR	/var/spool/mail

#
# If defined, file which inhibits all the usual chatter during the login
# sequence.  If a full pathname, then hushed mode will be enabled if the
# user's name or shell are found in the file.  If not a full pathname, then
# hushed mode will be enabled if the file exists in the user's home directory.
#
HUSHLOGIN_FILE	.hushlogin
#HUSHLOGIN_FILE	/etc/hushlogins

#
# *REQUIRED*  The default PATH settings, for superuser and normal users.

#
# Terminal permissions
#
#	TTYGROUP	Login tty will be assigned this group ownership.
#	TTYPERM		Login tty will be set to this permission.
#
# If you have a "write" program which is "setgid" to a special group
# which owns the terminals, define TTYGROUP to the group number and
# TTYPERM to 0620.  Otherwise leave TTYGROUP commented out and assign
# TTYPERM to either 622 or 600.
#
TTYGROUP	tty
TTYPERM		0600

#
# Login configuration initializations:
#
#	ERASECHAR	Terminal ERASE character ('\010' = backspace).

#	UMASK		Default "umask" value.
#
# The ERASECHAR and KILLCHAR are used only on System V machines.
# The ULIMIT is used only if the system supports it.
# (now it works with setrlimit too; ulimit is in 512-byte units)
#
# Prefix these values with "0" to get octal, "0x" to get hexadecimal.
#
ERASECHAR	0177
KILLCHAR	025
UMASK		077

#
#	PASS_MAX_DAYS	Maximum number of days a password may be used.

# Which fields may be changed by regular users using chfn - use
# any combination of letters "frwh" (full name, room number, work
# phone, home phone).  If not defined, no changes are allowed.
# For backward compatibility, "yes" = "rwh" and "no" = "frwh".
# 
CHFN_RESTRICT		rwh

#
# List of groups to add to the user's supplementary group set
# when logging in on the console (as determined by the CONSOLE
# setting).  Default is none.
#

# access to these groups, even when not logged in on the console.
# How to do it is left as an exercise for the reader...

# (examples: 022 -> 002, 077 -> 007) for non-root users, if the uid is
# the same as gid, and username is the same as the primary group name.
#
# This also enables userdel to remove user groups if no members exist.
#
USERGROUPS_ENAB yes

#
# Controls display of the motd file. This is better handled by pam_motd.so
# so the declaration here is empty is suppress display by readers of this
