NAME
       pfconfig - Configure packet filter parameters

SYNOPSIS
       /usr/sbin/pfconfig   [+/-p[romisc]]   [+/-c[opyall]]  [-b[acklog]  nnn]
       [-a[ll]] [interface-name...]

DESCRIPTION
       The pfconfig command allows the system  manager	to  configure  certain
       parameters  of  the  packet  filter driver (see packetfilter(7)). These
       parameters are configured separately for each interface; the interfaces
       are  specified by name on the command line (for example, ln0, and ni1).
       If more than one interface is specified, they are all  given  the  same
       settings.   Alternatively,  you	can  specify -all to configure all the
       packet-filter interfaces on the system.

       You can set the following parameters with pfconfig: Allows packet  fil‐
       ter  users  to  set  the	 interface into promiscuous mode (receives all
       packets).  Whenever there is at least one packet filter descriptor open
       with  the ENPROMISC mode bit set, the interface is put into promiscuous
       mode.  When no such descriptors are in use, the interface  is  returned
       to  normal  mode.  The interface is no longer put into promiscuous mode
       on behalf of packet filter users; if the interface  is  in  promiscuous
       mode  when  this command is given, it is returned to normal mode.  (The
       superuser may use ifconfig(8) to control promiscuous  mode,  overriding
       the  mode set by non-superusers.	 This is the default setting.)	Allows
       packet filter users to set the interface into copy-all  mode  (receives
       packets	sent/received  by  the	kernel-resident protocol software [for
       example, IP, ARP, DECnet, LAT] on this  host).  Whenever	 there	is  at
       least  one  packet  filter  descriptor open with the ENCOPYALL mode bit
       set, the interface is put into copy-all mode.  When no such descriptors
       are in use, the interface is returned to normal mode.  The interface is
       no longer put into copy-all mode on behalf of packet filter  users;  if
       the  interface  is  in  copy-all mode when this command is given, it is
       returned to normal mode.	 (The superuser may use ifconfig(8) to control
       copy-all	 mode,	overriding the mode set by non-superusers. This is the
       default setting.)  Sets the maximum backlog (packet filter input	 queue
       length)	for non-superuser descriptors to the specified number.	When a
       descriptor is opened, it is given a  queue  length  limit  of  two.  An
       application can increase this backlog using the EIOCSETW ioctl request.
       Superusers are allowed to increase their backlog up  to	a  system-wide
       maximum;	 non-superusers	 are allowed to increase their backlog only up
       to the maximum set by this program.  Note that  allowing	 too  large  a
       backlog	may  result  in vast amounts of kernel memory being tied up in
       the packet filter driver queues.

	      If no configuration parameters are specified, the pfconfig  com‐
	      mand  displays  the  current packet filter configuration for the
	      network interfaces.

	      Only the superuser may use this command to change the configura‐
	      tion.

DIAGNOSTICS
       PACKETFILTER option is not built into the running kernel

	      Explanation:

	      Packetfilter  support  is not built into the kernel. Reconfigure
	      the kernel with the packetfilter option.	pfopen: xxx:  No  such
	      device

	      Explanation:

	      The specified network device does not exist on the system, or no
	      pfilt minor devices exist in the /dev/pf	directory.   pfconfig:
	      your  system may not be properly configured; see "man packetfil‐
	      ter"

	      Explanation:

	      No pfilt minor devices exist in the /dev/pf  directory.	pfcon‐
	      fig:  either network interface 'xxx' is down, or your system may
	      not be properly configured; see "man packfilter"

	      Explanation:

	      The specified network device is not up and  running.   pfconfig:
	      either  all  of your network interfaces are down, or your system
	      may not be properly configured; see "man packfilter"

	      Explanation:

	      No network devices are up and running.
