-.Dd May 9, 1995
-.Dt SYSCTL 8
-.Os
-.Sh NAME
-.Nm sysctl
-.Nd get or set kernel state
-.Sh SYNOPSIS
-.Nm sysctl
-.Op Fl n
-.Ar name ...
-.Nm sysctl
-.Op Fl n
-.Fl w
-.Ar name=value ...
-.Nm sysctl
-.Op Fl n
-.Fl aA
-.Sh DESCRIPTION
-The
-.Nm sysctl
-utility retrieves kernel state and allows processes with
-appropriate privilege to set kernel state.
-The state to be retrieved or set is described using a
-``Management Information Base'' (``MIB'') style name,
-described as a dotted set of components.
-The
-.Fl a
-flag can be used to list all the currently available string or integer values.
-The
-.Fl A
-flag will list all the known MIB names including tables.
-Those with string or integer values will be printed as with the
-.Fl a
-flag; for the table values,
-the name of the utility to retrieve them is given.
-.Pp
-The
-.Fl n
-flag specifies that the printing of the field name should be
-suppressed and that only its value should be output.
-This flag is useful for setting shell variables.
-For example, to save the pagesize in variable psize, use:
-.Bd -literal -offset indent -compact
-set psize=`sysctl -n hw.pagesize`
-.Ed
-.Pp
-If just a MIB style name is given,
-the corresponding value is retrieved.
-If a value is to be set, the
-.Fl w
-flag must be specified and the MIB name followed
-by an equal sign and the new value to be used.
-.Pp
-The information available from
-.Nm sysctl
-consists of integers, strings, and tables.
-The tabular information can only be retrieved by special
-purpose programs such as
-.Nm ps ,
-.Nm systat ,
-and
-.Nm netstat .
-The string and integer information is summarized below.
-For a detailed description of these variable see
-.Xr sysctl 3 .
-The changeable column indicates whether a process with appropriate
-privilege can change the value.

-The
-.Nm sysctl
-program can get or set debugging variables
-that have been identified for its display.
-This information can be obtained by using the command:
-.Bd -literal -offset indent
-sysctl debug
-.Ed
-In addition,
-.Nm sysctl
-can extract information about the filesystems that have been compiled
-into the running system.
-This information can be obtained by using the command:
-.Bd -literal -offset indent
-sysctl vfs
-.Ed
-By default, only filesystems that are actively being used are listed.
-Use of the
-.Fl A
-flag lists all the filesystems compiled into the running kernel.
-.Sh EXAMPLES
-For example, to retrieve the maximum number of processes allowed
-in the system, one would use the follow request:
-.Bd -literal -offset indent -compact
-sysctl kern.maxproc
-.Ed
-.Pp
-To set the maximum number of processes allowed
-in the system to 1000, one would use the follow request:
-.Bd -literal -offset indent -compact
-sysctl -w kern.maxproc=1000
-.Ed
-.Pp
-Information about the system clock rate may be obtained with:
-.Bd -literal -offset indent -compact
-sysctl kern.clockrate
-.Ed
-.Pp
-Information about the load average history may be obtained with
-.Bd -literal -offset indent -compact
-sysctl vm.loadavg
-.Ed
-.Pp
-To make the
-.Xr chown 2
-system call use traditional BSD semantics (don't clear setuid/setgid bits),
-one would do the following:
-.Bd -literal -offset indent -compact
-sysctl -w fs.posix.setuid=0
-.Ed
-.Pp
-Set the list of reserved TCP ports that should not be allocated
-by the kernel dynamically.  This can be used to keep daemons
-from stealing a specific port that another program needs to function.
-List elements may be separated by commas and/or whitespace.
-.Bd -literal -offset indent -compact
-sysctl -w net.inet.tcp.baddynamic=749,750,751,760,761,871
-.Ed
-.Pp
-It is also possible to add or remove ports from the current list.
-.Bd -literal -offset indent -compact
