PFS(8)                      System Manager's Manual                     PFS(8)

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.
