.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is intended to view and change configuration of the
|
|
.Xr pfil 9
|
|
packet filtering hooks and filters on them.
|
|
.Sh COMMANDS

|
.Bl -tag -width "unlink"

|
|

.Ar hook Ar head

|
|
Link
|
|
.Ar hook
|
|
to
|
|
.Ar head .
|
|
With the
|
|
.Fl i
|
|
flag the hook will be connected as input and with
|
|
.Fl o
|
|
as output hook.
|
|
At least one of
|
|
.Fl i
|
|
or
|
|
.Fl o
|
|
is required.
|
|
By default
|
|
.Nm
|
|
will prepend the hook in front of other hooks if any present:
|
|
new hook will be as close to the wire as possible, so that on input
|
|
it will be the first filter and on output it will be the last.
|
|
Adding the
|
|
.Fl a
|
|
flag switches to appending new hook instead of prepending.

|
|
or
|

|
|
With the
|
|
.Fl i
|
|
flag the hook will be removed from the input list of hooks
|
|
and with
|
|
.Fl o
|
|
on output list.
