PFS(8) BSD System Manager's Manual PFS(8)NAMEpfs — save and restore information for NAT and state tables
SYNOPSISpfs [-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.
