pfs -- save and restore information for NAT and state tables
SYNOPSIS
pfs [-v] -l
pfs [-bv] -R filename
pfs [-bv] -r filename
pfs [-v] -u
pfs [-bv] -W filename
pfs [-bv] -w filename
DESCRIPTION
The pfs command allows state information created for NAT entries and rules using ``keep state'' to be locked (modification prevented) and
then saved to disk, allowing for the system to experience a reboot, followed by the restoration of that information, resulting in connections
not being interrupted.
OPTIONS -b The information are read or stored using binary format. The default format is a readable ASCII format, similar to pfctl.conf
syntax.
-l Lock state tables in the kernel.
-R filename Restore information from filename and load it into the kernel. The state tables are locked at the beginning of this operation
and unlocked once complete.
-r filename Read information in from filename and load it into the kernel. This requires the state tables to have already been locked and
does not change the lock once complete.
-u Unlock state tables in the kernel.
-v Provide a verbose description of what's being done.
-W filename Write information from the kernel out to filename. The state tables are locked at the beginning of this operation and
unlocked once complete.
-w filename Write information from the kernel out to filename. This requires the state tables to have already been locked and does not
change the lock once complete.

pfstag - Set or remove tags to/from pfs stream
SYNOPSIS
pfstag [--set [channel:]name=value] [--remove [channel:]name]
DESCRIPTION
Use this command to set or remove tags from the pfs-stream. Tags are used to add additional information to pfs frames and they are in the
format: 'name=value'. To learn more about tags, read 'Specification of the PFS File Format'.
Tags are set/removed to/from all pfs frames in the stream.
Note that currently only OpenEXR file format supports tags.
OPTIONS --set [channel:]name=value], -s [channel:]name=value], --add [channel:]name=value]
Change existing or add a new tag of the given name. If no channel is given, tags are added to the frame.
--remove [channel:]name], -r [channel:]name]
Remove tag of the given name. Ignore if the tag does not exist. If no channel is given, tags are removed from the frame.
EXAMPLES
pfsin memorial.hdr | pfstag --add "EXTRA_INFO=foo" | pfsout memorial_ei.exr
Add tag "EXTRA_INFO=foo" to the memorial image and save it as memorial_ei.exr.
