IPFS(8)								       IPFS(8)

NAME
       ipfs - saves and	restores information for NAT and state tables.

SYNOPSIS
       ipfs [-nv] -l

       ipfs [-nv] -u

       ipfs [-nv] [ -d <dirname> ] -R

       ipfs [-nv] [ -d <dirname> ] -W

       ipfs [-nNSv] [ -f <filename> ] -r

       ipfs [-nNSv] [ -f <filename> ] -w

       ipfs [-nNSv] -f <filename> -i <if1>,<if2>

DESCRIPTION
       ipfs  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
       -d     Change  the  default  directory  used with -R and	-W options for
	      saving state information.

       -n     Don't actually take any action  that  would  affect  information
	      stored in	the kernel or on disk.

       -v     Provides a verbose description of	what's being done.

       -i <ifname1>,<ifname2>
	      Change all instances of interface	name ifname1 in	the state save
	      file to ifname2.	Useful if you're restoring  state  information
	      after a hardware reconfiguration or change.

       -N     Operate on NAT information.

       -S     Operate on filtering state information.

       -u     Unlock state tables in the kernel.

       -l     Lock state tables	in the kernel.

       -r     Read information in from the specified file and load it into the
	      kernel.  This requires the state tables  to  have	 already  been
	      locked and does not change the lock once complete.

       -w     Write information	out to the specified file and from the kernel.
	      This requires the	state tables to	have already been  locked  and
	      does not change the lock once complete.

       -R     Restores	all  saved  state information, if any, from two	files,
	      ipstate.ipf and ipnat.ipf, stored	in the	/var/db/ipf  directory
	      unless  otherwise	 specified by the -d option.  The state	tables
	      are locked at the	beginning of this operation and	unlocked  once
	      complete.

       -W     Saves  in-kernel	state  information,  if	any, out to two	files,
	      ipstate.ipf and ipnat.ipf, stored	in the	/var/db/ipf  directory
	      unless  otherwise	 specified by the -d option.  The state	tables
	      are locked at the	beginning of this operation and	unlocked  once
	      complete.

FILES
       /var/db/ipf/ipstate.ipf
       /var/db/ipf/ipnat.ipf
       /dev/ipl
       /dev/ipstate
       /dev/ipnat

SEE ALSO
       ipf(8), ipl(4), ipmon(8), ipnat(8)

DIAGNOSTICS
       Perhaps the -W and -R operations	should set the locking but rather than
       undo it,	restore	it to what it was previously.  Fragment	table informa-
       tion is currently not saved.

BUGS
       If you find any,	please send email to me	at darrenr@pobox.com
