# # /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 # REQUIRED for useradd/userdel/usermod # Directory where mailboxes reside, _or_ name of file, relative to the # home directory. If you _do_ define MAIL_DIR and MAIL_FILE, # MAIL_DIR takes precedence. # # Essentially: # - MAIL_DIR defines the location of users mail spool files # (for mbox use) by appending the username to MAIL_DIR as defined # below. # - MAIL_FILE defines the location of the users mail spool files as the # fully-qualified filename obtained by prepending the user home # directory before $MAIL_FILE # # NOTE: This is no more used for setting up users MAIL environment variable # which is, starting from shadow 4.0.12-1 in Debian, entirely the # job of the pam_mail PAM modules # See default PAM configuration files provided for # login, su, etc. # # This is a temporary situation: setting these variables will soon # move to /etc/default/useradd and the variables will then be # no more supported MAIL_DIR /var/mail #MAIL_FILE .mail # # Enable logging and display of /var/log/faillog login failure info. # This option conflicts with the pam_tally PAM module. # FAILLOG_ENAB yes # # Enable display of unknown usernames when login failures are recorded. # # WARNING: Unknown usernames may become world readable. # See #290803 and #298773 for details about how this could become a security # concern LOG_UNKFAIL_ENAB no # # Enable logging of successful logins # LOG_OK_LOGINS no # # 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, all su activity is logged to this file. # #SULOG_FILE /var/log/sulog # # 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, login failures will be logged here in a utmp format # last, when invoked as lastb, will read /var/log/btmp, so... # FTMP_FILE /var/log/btmp # # If defined, the command name to display when running "su -". For # example, if this is defined as "su" then a "ps" will display the # command is "-su". If not defined, then "ps" would display the # name of the shell actually being run, e.g. something like "-sh". # SU_NAME su # # If defined, file which inhibits all the usual chatter during the login # sequence.

Otherwise leave TTYGROUP commented out and assign # TTYPERM to either 622 or 600. # # In Debian /usr/bin/bsd-write or similar programs are setgid tty # However, the default and recommended value for TTYPERM is still 0600 # to not allow anyone to write to anyone else console or terminal # Users can still allow other people to write them by issuing # the "mesg y" command.
