+.Dt LOGIN.CONF 5
+.Os FreeBSD
+.Sh NAME
+.Nm login.conf
+.Nd login class capability database
+.Sh SYNOPSIS
+.Pa /etc/login.conf ,
+.Pa ~/.login_conf
+.Sh DESCRIPTION
+login.conf contains various attributes and capabilities of login classes.
+A login class (an optional annotation against each record in the user
+account database,
+.Pa /etc/master.passwd )
+determines session accounting, resource limits and user environment settings.
+It is used by various programs in the system to set up a user's login
+environment and to enforce policy, accounting and administrative restrictions.
+It also provides the means by which users are able to be
+authenticated to the system and the types of authentication available.
+.Pp
+A special record "default" in the system user class capability database
+.Pa /etc/login.conf
+is used automatically for any
+non-root user without a valid login class in
+.Pa /etc/master.passwd .
+A user with a uid of 0 without a valid login class will use the record
+"root" if it exists, or "default" if not.
+.Pp
+In FreeBSD, users may individually create a file called
+.Pa .login_conf
+in their home directory using the same format, consisting of a single
+entry with a record id of "me".
+If present, this file is used by
+.Xr login 1
+to set user-defined environment settings which override those specified
+in the system login capabilities database.
+Only a subset of login capabilities may be overridden, typically those
+which do not involve authentication, resource limits and accounting.
+.Pp
+Records in a class capabilities database consist of a number of
+colon-separated fields.
+The first entry for each record gives one or more names that a record is
+to be known by, each separated by a '|' character.
+The first name is the most common abbreviation.
+The last name given should be a long name that is more descriptive
+of the capability entry, and all others are synonyms.
+All names but the last should be in lower case and contain no blanks;
+the last name may contain upper case characters and blanks for
+readability.
+.Pp
+See
+.Xr getcap 3
+for a more in-depth description of the format of a capability database.
+.Sh CAPABILITIES
+Fields within each record in the database follow the
+.Xr getcap 3
+conventions for boolean, type string
+.Ql \&= 
+and type numeric
+.Ql \&# ,
+although type numeric is depreciated in favour of the string format and
+either form is accepted for a numeric datum.
+Values fall into the following categories:
+.Bl -tag -width "program"
+.It file
+Path name to a data file
+.It program
+Path name to an executable file
+.It list
+A list of values (or pairs of values) separated by commas or spaces
+.It path
+A space or comma separated list of path names, following the usual csh
+conventions (leading tilde with and without username being expanded to
+home directories etc.)
+.It number
+A numeric value, either decimal (default), hexadecimal (with leading 0x),
+or octal (with a leading 0).
+With a numeric type, only one numeric value is allowed.
+Numeric types may also be specified in string format (ie. the capability
+tag being delimited from the value by '=' instead of '#').
+Whichever method is used, then all records in the database must use the
+same method to allow values to be correctly overridden in interpolated
+records.
+.It size
+A number which expresses a size.
+The default interpretation of a value is the number of bytes, but a
+suffix may specify alternate units:
+.Bl -tag -offset indent -compact -width xxxx
+.It b
+explicitly selects 512-byte blocks
+.It k
+selects kilobytes (1024 bytes)
+.It m
+specifies a multiplier of 1 megabyte (1048576 bytes),
+.It g
+specifies units of gigabytes, and
+.It t
+represents terrabytes.
+.El
+A size value is a numeric quantity and case of the suffix is not significant.
+Concatenated values are added together.
+.It time
+A period of time, by default in seconds.
+A prefix may specify a different unit;
+.Bl -tag -offset indent -compact -width xxxx
+.It y
+indicates the number of 365 day years,
+.It w
+indicates the number of weeks,
+.It d
+the number of days,
+.It h
+the number of minutes, and
+.It s
+the number of seconds.
+.El
+Concatenated values are added together.
+For example, 2 hours and 40 minutes may be written either as
+9600s, 160m or 2h40m.
+.El
+.Pp
+The usual convention to interpolate capability entries using the special
+.Em tc=value
+notation may be used.
+.Pp
+.Sh RESOURCE LIMITS
+.Bl -column coredumpsize indent indent
+.Sy Name	Type	Notes	Description
+.It cputime	time		CPU usage limit.
+.It filesize	size		Maximum file size limit.
+.It datasize	size		Maximum data size limit.

+.It memorylocked	size		Maximum locked in core memory size limit.
+.It maxproc	number		Maximum number of processes.
+.It openfiles	number		Maximum number of open files per process.
+.El
+.Pp
+These resource limit entries actually specify both the maximum
+and current limits (see
+.Xr getrlimit 2 ).
+The current (soft) limit is the one normally used, although the user is permitted
+to increase the current limit to the maximum (hard) limit.
+The maximum and current limits may be specified individually by appending a
+-max or -cur to the capability name.
+.Pp
+.Sh ENVIRONMENT
+.Bl -column ignorenologin indent xbinxxusrxbin
+.Sy Name	Type	Notes	Description
+.It charset	string		Set $MM_CHARSET environment variable to the specified
+value.
+.It hushlogin	bool	false	Same as having a ~/.hushlogin file.
+.It ignorenologin	bool	false	Login not prevented by nologin.
+.It lang	string		Set $LANG environment variable to the specified value.
+.It manpath	path		Default search path for manpages.
+.It nologin	file		If the file exists it will be displayed and
+the login session will be terminated.
+.It path	path	/bin /usr/bin	Default search path.
+.It priority	number		Initial priority (nice) level.
+.It requirehome 	bool	false	Require a valid home directory to login.
+.It setenv	list		A comma-separated list of environment variables and
+values to which they are to be set.
+.It shell	prog		Session shell to execute rather than the
+shell specified in the passwd file. The SHELL environment variable will
+contain the shell specified in the password file.
+.It term	string	su	Default terminal type if not able to determine from
+other means.
+.It timezone	string		Default value of $TZ environment variable.
+.It umask	number	022	Initial umask. Should always have a leading 0 to
+ensure octal interpretation.
+.It welcome	file	/etc/motd	File containing welcome message.
+.El
+.Pp
+.Sh AUTHENTICATION
+.Bl -column minpasswordlen indent indent
+.Sy Name	Type	Notes	Description
+.It minpasswordlen	number	6	The minimum length a local password may be.
+.\" .It approve	program 	Program to approve login.
+.It auth	list	passwd	Allowed authentication styles. The first value is the
+default style.
+.It auth-<type>	list		Allowed authentication styles for the
+authentication type 'type'.
+.It copyright	file		File containing additional copyright information
+.\".It widepasswords	bool	false	Use the wide password format. The wide password
+.\" format allows up to 128 significant characters in the password.
+.It host.allow	list		List of remote host wildcards from which users in
+the class may access.
+.It host.deny	list		List of remote host wildcards from which users in
+the class may not access.
+.It times.allow 	list		List of time periods during which
+logins are allowed.
+.It times.deny	list		List of time periods during which logins are
+disallowed.
+.It tty.allow	list		List of ttys and ttygroups which users
+in the class may use for access.
+.It tty.deny	list		List of ttys and ttygroups which users
+in the class may not use for access.
+.El
+.Pp
+These fields are intended to be used by
+.Xr passwd 1
+and other programs in the login authentication system.
+.Pp
+Capabilities that set environment variables are scanned for both
+.Ql \&~
+and
+.Ql \&$
+characters, which are substituted for a user's home directory and name
+respectively.
+To pass these characters literally into the environment variable, escape
+the character by preceding it with a backslash '\\'.
+.Pp
+The
+.Em host.allow
+and
+.Em host.deny
+entries are comma separated lists used for checking remote access to the system,
+and consist of a list of hostnames and/or IP addresses against which remote
+network logins are checked.
+Items in these lists may contain wildcards in the form used by shell programs
+for wildcard matching (See
+.Xr fnmatch 3
+for details on the implementation).
+The check on hosts is made against both the remote system's Internet address
+and hostname (if available).
+If both lists are empty or not specified, then logins from any remote host
+are allowed.
+If host.allow contains one or more hosts, then only remote systems matching
+any of the items in that list are allowed to log in.
+If host.deny contains one or more hosts, then a login from any matching hosts
+will be disallowed.
+.Pp
+The
+.Em times.allow
+and
+.Em times.deny
+entries consist of a comma-separated list of time periods during which the users
+in a class are allowed to be logged in.
+These are expressed as one or more day codes followed by a start and end times
+expressed in 24 hour format, separated by a hyphen or dash.
+For example, MoThSa0200-1300 translates to Monday, Thursday and Saturday between
+the hours of 2 am and 1 p.m..
+If both of these time lists are empty, users in the class are allowed access at
+any time.
+If
+.Em times.allow
+is specified, then logins are only allowed during the periods given.
+If
+.Em times.deny
+is specified, then logins are denied during the periods given, regardless of whether
+one of the periods specified in
+.Em times.allow
+applies.
+.Pp
+Note that
+.Xr login 1
+enforces only that the actual login falls within periods allowed by these entries.
+Further enforcement over the life of a session requires a separate daemon to
+monitor transitions from an allowed period to a non-allowed one.
+.Pp
+The
+.Em tty.allow
+and
+.Em tty.deny
+entries contain a comma-separated list of tty devices (without the /dev/ prefix)
+that a user in a class may use to access the system, and/or a list of ttygroups
+(See
+.Xr getttyent 3
+and
+.Xr ttys 5
+for information on ttygroups).
+If neither entry exists, then the choice of login device used by the user is
+unrestricted.
+If only
+.Em tty.allow
+is specified, then the user is restricted only to ttys in the given
+group or device list.
+If only
+.Em tty.deny
+is specified, then the user is prevented from using the specified devices or
+devices in the group.
+If both lists are given and are non-empty, the user is restricted to those
+devices allowed by tty.allow that are not available by tty.deny.
+.Sh ACCOUNTING LIMITS
+.Bl -column passwordperiod indent indent
+.Sy Name	Type	Notes	Description
+.It accounted	bool	false	Enable session time accounting for all users
+in this class.
+.It autodelete	time		Time after expiry when account is auto-deleted.
+.It bootfull	bool	false	Enable 'boot only if ttygroup is full' strategy
+when terminating sessions.
+.It daytime	time		Maximum login time per day.
+.It expireperiod	time		Time for expiry allocation.
+.It graceexpire 	time		Grace days for expired account.

+.Sh DESCRIPTION
+This set of functions checks to see if login is allowed based on login
+class capability entries in the login database,
+.Xr login.conf 5 .
+.Pp
+.Fn auth_ttyok
+checks to see if the named tty is available to users of a specific
+class, and is either in the 
+.Em ttys.allow
+access list, and not in
+the 
+.Em ttys.deny
+access list.
+An empty 
+.Em ttys.allow
+list (or if no such capability exists for
+the give login class) logins via any tty device are allowed unless
+the 
+.Em ttys.deny
+list exists and is non-empty, and the device or its
+tty group (see
+.Xr ttys 5 )
+is not in the list.
+Access to ttys may be allowed or restricted specifically by tty device
+name, a device name which includes a wildcard (e.g. ttyD* or cuaD*),
+or may name a ttygroup, when group=<name> tags have been assigned in
+.Pa /etc/ttys .
+Matching of ttys and ttygroups is case sensitive.
+Passing a 
+.Dv NULL
+or empty string as the
+.Ar tty
+parameter causes the function to return a non-zero value.
+.Pp
+.Fn auth_hostok
+checks for any host restrictions for remote logins.
+The function checks on both a host name and IP address (given in its
+text form, typically n.n.n.n) against the 
+.Em host.allow
+and 
+.Em host.deny
+login class capabilities.
+As with ttys and their groups, wildcards and character classes may be
+used in the host allow and deny capability records.
+The
+.Xr fnmatch 3
+function is used for matching, and the matching on hostnames is case
+insensitive.
+Note that this function expects that the hostname is fully expanded
+(i.e. the local domain name added if necessary) and the IP address
+is in its canonical form.
+No hostname or address lookups are attempted.
+.Pp
+It is possible to call this function with either the hostname or
+the IP address missing (i.e. 
+.Dv NULL )
+and matching will be performed
+only on the basis of the parameter given.
+Passing
+.Dv NULL
+or empty strings in both parameters will result in
+a non-zero return value.
+.Pp
+The
+.Fn auth_timeok
+function checks to see that a given time value is within the
+.Em times.allow
+login class capability and not within the
+.Em times.deny
+access lists.
+An empty or non-existent 
+.Em times.allow
+list allows access at any
+time, except if a given time is falls within a period in the
+.Em times.deny
+list.
+The format of time period records contained in both
+.Em times.allow
+and
+.Em times.deny
+capability fields is explained in detail in the
+.Xr login_times 3
+manual page.
+.Sh RETURN VALUES
+A non-zero return value from any of these functions indicates that
+login access is granted.
+A zero return value means either that the item being tested is not
+in the 
+.Em allow
+access list, or is within the
+.Em deny
+access list.

+.Fn parse_lt "const char *str"

+.Ft int
+.Fn in_ltms "const login_time_t *lt" "struct tm *t" "time_t *ends"
+.Sh DESCRIPTION
+This set of functions may be used for parsing and checking login and
+session times against a predefined list of allowed login times as
+used in
+.Xr login.conf 5 .
+.Pp
+The format of allowed and disallowed session times specified in the
+.Ar times.allow
+and
+.Ar times.deny
+capability fields in a login class are comprised of a prefix which
+specifies one or more 2- or 3-character day codes, followed by
+a start and end time in 24 hour format separated by a hyphen.
+Day codes may be concatenated together to select specific days, or
+the special mnemonics "Any" and "All" (for any/all days of the week),
+"Wk" for any day of the week (excluding Saturdays and Sundays) and
+"Wd" for any weekend day may be used.
+.Pp
+For example, the following time period:
+.Dl MoThFrSa1400-2200
+is interpreted as Monday, Thursday through Saturday between the hours
+of 2pm and 10pm.
+.Dl Wd0600-1800
+means Saturday and Sunday, between the hours of 6am through 6pm, and
+.Dl Any0400-1600
+means any day of the week, between 4am and 4pm.
+.Pp
+Note that all time periods reference system local time.
+.Pp
+The
+.Fn parse_lt
+function converts the ascii representation of a time period into
+a structure of type
+.Ft login_time_t .
+This is defined as:
+.Bd -literal
+typedef struct login_time
+{
+  u_short	lt_start;   /* Start time */
+  u_short	lt_end;	    /* End time */
+  u_char	lt_dow;	    /* Days of week */
+} login_time_t;
+.Ed
+.Pp
+The
+.Ar lt_start
+and
+.Ar lt_end
+fields contain the number of minutes past midnight at which the
+described period begins and ends.
+The
+.Ar lt_dow
+field is a bit field, containing one bit for each day of the week
+and one bit unused.
+A series
+.Em LTM_*
+macros may be used for testing bits individually and in combination.
+If no bits are set in this field - ie. it contains the value
+.Em LTM_NONE -
+then the entire period is assumed invalid.
+This is used as a convention to mark the termination of an array
+of login_time_t values.
+If
+.Fn parse_lt
+returns a
+.Ar login_time_t
+with
+.Ar lt_dow
+equal to
+.Em LTM_NONE
+then a parsing error was encountered.
+.Pp
+The remaining functions provide the ability to test a given time_t or
+struct tm value against a specific time period or array of time
+periods.
+.Fn in_ltm
+determines whether the given time described by the struct tm
+passed as the second parameter falls within the period described
+by the first parameter.
+A boolean value is returned, indicating whether or not the time
+specified falls within the period.
+If the time does fall within the time period, and the third
+parameter to the function is not NULL, the time at which the
+period ends relative to the time passed is returned.
+.Pp
+The
+.Fn in_ltms 
+function is similar to
+.Fn in_ltm
+except that the first parameter must be a pointer to an array
+of login_time_t objects, which is up to LC_MAXTIMES (64)
+elements in length, and terminated by an element with its
+.Ar lt_dow
+field set to
+.Em LTM_NONE.
+.Sh RETURN VALUES
+.Fn parse_lt
+returns a filled in structure of type login_time_t containing the
+parsed time period.
+If a parsing error occurs, the lt_dow field is set to
+.Em LTM_NONE
+(i.e. 0).
+.Pp
+.Fn in_ltm
+returns non-zero if the given time falls within the period described
+by the login_time_t passed as the first parameter.
+.Pp
+.Fn in_ltms
+returns the index of the first time period found in which the given
+time falls, or -1 if none of them apply.

+Ethernet device driver for the Intel EtherExpress Pro/10
+.Sh SYNOPSIS
+.Cd "device ex0 at isa? port? net irq? vector exintr"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the 16-bit PCI Intel EtherExpress Pro/10 Ethernet
+card based on the Intel i82595 chip.
+.Pp
+If the port start address isn't found, the card will be searched for in the
+I/O address range 0x200 - 0x3a0.  If the IRQ isn't specified, it will be
+read from the EEPROM on the card.
+.Pp
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "ex%d: Intel EtherExpress Pro/10, address %6D, connector %s"
+The device probe found an installed card, and was able to correctly install
+the device driver.
+.It "ex%d: WARNING: board's EEPROM is configured for IRQ %d, using %d"
+The device probe detected that the board is configured for a different 
+interrupt than the one specified in the kernel configuration file.
+.It "ex%d: invalid IRQ."
+The device probe detected an invalid IRQ setting.
+.El
+.Pp
+.Sh BUGS
+Currently the driver does not support multicast.

+.Sh NAME
+.Nm limits
+.Nd Set or display process resource limits
+.Sh SYNOPSIS
+.Nm limits
+.Op Fl C Ar class | Fl U Ar user
+.Op Fl SHB
+.Op Fl e
+.Op Fl cdflmnstu Op val
+.Nm limits
+.Op Fl C Ar class | Fl U Ar user
+.Op Fl SHB
+.Op Fl cdflmnstu Op val
+.Op Fl E
+.Op Ar name=value ...
+.Op Ar command
+.Sh DESCRIPTION
+.Nm Limits
+ether prints or sets kernel resource limits, and may optionally set
+environment variables like
+.Xr env 1
+and run a program with the selected resources.
+Three uses of the
+.Nm limits
+command are possible:
+.Pp
+.Bl -hang -width indent
+.It Nm limits Op Ar limitflags
+.Op Ar name=value
+.Ar command
+.Pp
+This usage sets limits according to
+.Ar limitflags ,
+optionally sets environment variables given as
+.Ar name=value
+pairs, and then runs the specified command.
+.It Nm limits Op Ar limitflags
+.Pp
+This usage determines values of resource settings according to
+.Ar limitflags ,
+does not attempt to set them and outputs these values to
+standard output.
+By default, this will output the current kernel resource settings
+active for the calling process.
+Using the
+.Fl C Ar class
+or
+.Fl U Ar user
+flags, you may also display the current resource settings modified
+by the the appropriate login class resource limit entries from
+the
+.Xr login.conf 5
+login capabilities database.
+.It Nm limits Fl e Op Ar limitflags
+.Pp
+This usage determines values of resource settings according to
+.Ar limitflags ,
+but does not set them itself.
+Like the previous usage it outputs these values to standard
+output, except that it will emit them in
+.Em eval
+format, suitable for the calling shell.
+The calling shell is determined by examining the entries in the
+.Pa /proc
+filesystem for the parent process.
+If the shell is known (ie. it is one of sh, csh, bash, tcsh, ksh,
+pdksh or rc),
+.Nm limits
+emits 'limit' or 'ulimit' commands in the format understood by
+that shell.
+If the name of the shell cannot be determined, then the 'ulimit'
+format used by
+.Pa /bin/sh
+is used.
+.Pp
+This is very useful for setting limits used by scripts, or prior
+launching of daemons and other background tasks with specific
+resource limit settings, and provides the benefit of allowing
+global configuration of maximum resource usage by maintaining a
+central database of settings in the login class database.
+.Pp
+Within a shell script,
+.Nm limits
+will normally be used with eval within backticks as follows:
+.Pp
+.Dl eval `limits -e -C daemon`
+.Pp
+which causes the output of
+.Nm limits
+to be evaluated and set by the current shell.
+.El
+.Pp
+The value of limitflags specified in the above contains one or more of the
+following options:
+.Pp
+.Bl -tag -width "-d [limit]"
+.It Fl C Ar class
+Use current resource values, modified by the resource entries applicable
+for the login class "class".
+.It Fl U Ar user
+Use current resource values, modified by the resource entries applicable
+to the login class which "user" belongs to.
+If the user does not belong to a class, then the resource capabilities
+for the "default" class are used, if it exists, or the "root" class if
+the user is a superuser account.
+.It Fl S
+Selects display or setting of "soft" (or current) resource limits.
+If specific limits settings follow this switch, only soft limits are
+affected unless overridden later with either the
+.Fl H
+or
+.Fl B
+flags.
+.It Fl H
+Selects display or setting of "hard" (or maximum) resource limits.
+If specific limits settings follow this switch, only hard limits are
+affected until overridden later with either the
+.Fl S
+or
+.Fl B
+flags.
+.It Fl B
+Selects display or setting of both "soft" (current) or "hard" (maximum)
+resource limits.
+If specific limits settings follow this switch, both soft and hard
+limits are affected until overridden later with either the
+.Fl S
+or 
+.Fl H
+flags.
+.Fl e
+Selects "eval mode" formatting for output.
+This is valid only on display mode and cannot be used when running a
+command.
+The exact syntax used for output depeneds upon the type of shell from
+which
+.Nm limits
+is invoked.
+.It Fl c Op Ar limit
+Selects or sets (if 'limit' is specified) the
+.Em coredumsize
+resource limit.
+A value of 0 disables core dumps.
+.It Fl d Op Ar limit
+Selects or sets (if 'limit' is specified) the
+.Em datasize
+resource limit.
+.It Fl f Op Ar limit
+Selects or sets the
+.Em filesize
+resource limit.
+.It Fl l Op Ar limit
+Selects or sets the
+.Em memorylocked
+resource limit.
+.It Fl m Op Ar limit
+Selects or sets the
+.Em memoryuse
+size limit
+.It Fl n Op Ar limit
+Selects or sets the
+.Em openfiles
+resource limit.
+.It Fl s Op Ar limit
+Selects or sets the
+.Em stacksize
+resource limit.
+.It Fl t Op Ar limit
+Selects or sets the
+.Em cputime
+resource limit.
+.It Fl u Op Ar limit
+Selects or sets the
+.Em maxproc
+resource limit.
+.Pp
+Valid values for 'limit' in the above set of flags consist of either the
+string 'infinity' or 'inf' for an infinite (or kernel-defined maximum)
+limit, or a numeric value maybe followed by a suffix.
+Values which relate to size default to a value in bytes, or one of the
+following suffixes may be used as a multiplier:
+.Pp
+.Bl -tag -offset indent -width "xxxx" -compact
+.It b
+512 byte blocks.
+.It k
+kilobytes (1024 bytes).
+.It m
+megabytes (1024*1024 bytes).
+.It g
+gigabytes.
+.It t
+terrabytes.
+.El
+.Pp
+The
+.Em cputime
+resource defaults to a number of seconds, but a multiplier may be
+used, and as with size values, multiple values separated by a valid
+suffix are added together:
+.Bl -tag -offset indent -width "xxxx" -compact
+.It s
+seconds.
+.It m
+minutes.
+.It h
+hours.
+.It d
+days.
+.It w
+weeks.
+.It y
+365 day years.
+.El
+.Pp
+.It Fl E
+The option
+.Sq Fl E
+causes
+.Nm limits
+to completely ignore the environment it inherits.
+.It Fl a
+This option forces all resource settings to be displayed even if
+other specific resource settings have been specified.
+For example, if you wish to disable core dumps when starting up
+the usenet news system, but wish to set all other resource settings
+as well that apply to the 'news' account, you might use:
+.Pp
+.Dl eval `limits -U news -aBec 0`
+.Pp
+As with the 
+.Xr setrlimit 3
+call, only the superuser may raise process "hard" resource limits.
+Non-root users may, however, lower them or change "soft" resource limits
+within to any value below the hard limit.
+When invoked to execute a program, the failure of
+.Nm limits
+to raise a hard limit is considered a fatal error.
+.El
+.Sh DIAGNOSTICS
+.Nm Limits
+exits with EXIT_FAILURE if usage is incorrect in any way; ie. an invalid
+option, or set/display options are selected in the same invocation,
+.Fl e
+is used when running a program, etc.
+When run in display or eval mode,
+.Nm limits
+exits with with a status of EXIT_SUCCESS.
+When run in command mode and execution of the command succeeds, the exit status
+will be whatever the executed program returns.
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr env 1 ,
+.Xr limit 1 ,
+.Xr sh 1 ,
+.Xr ulimit 1 ,
+.Xr getrlimit 3 ,
+.Xr setrlimit 3 ,
+.Xr login_cap 3 ,
+.Xr login.conf 5
+.Sh BUGS
+.Nm Limits
+does not handle commands with equal (``='') signs in their
+names, for obvious reasons.
+.Pp
+When eval output is selected, the /proc filesystem must be installed
+and mounted for the shell to be correctly determined, and therefore
+output syntax correct for the running shell.
+The default output is valid for /bin/sh, so this means that any
+usage of
+.Nm limits
+in eval mode prior mounting /proc may only occur in standard bourne
+shell scripts.
+.Pp
+.Nm Limits
+makes no effort to ensure that resource settings emitted or displayed
+are valid and settable by the current user.
+Only a superuser account may raise hard limits, and and when doing so
+the FreeBSD kernel will silently lower limits to values less than
+specified if the values given are too high.
