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, allow-
  ing 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
       effect information stored in the	kernel or on disk.

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

  -N   Operate on NAT information.

  -S   Operate on filtering state information.

  -u   Unlock state tables in the kernel.

  -l   Unlock state tables in the kernel.

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

  -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 comlete.

  -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 the -d option is used.  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 the -d option is used.  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

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 information
  is currently not saved.
