ipfs (ADMN)

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  experi-
     ence  a reboot, followed by the restoration of that informa-
     tion, 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 infor-
          mation 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 begin-
          ning 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 begin-
          ning 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.
