NAME
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.
