PFS(8)                  NetBSD 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.
