ipfs(1M)		System Administration Commands		      ipfs(1M)

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
       The  ipfs  utility  enables  the	 saving	 of  state  information across
       reboots. Specifically, the utility allows state information created for
       NAT  entries  and  rules	 using "keep state" to be locked (modification
       prevented) and then saved to disk. Then, after a reboot, that  informa‐
       tion  is	 restored. The result of this state-saving is that connections
       are not interrupted.

OPTIONS
       The following options are supported:

       -d

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

       -n

	   Do  not take any action that would affect information stored in the
	   kernel or on disk.

       -v

	   Provides a verbose description of ipfs activities.

       -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.
	   This directory can be changed with 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.
	   This directory can be changed with the -d option. The state	tables
	   are	locked	at  the	 beginning of this operation and unlocked once
	   complete.

NOTES
       To view license terms, attribution, and copyright for  IP  Filter,  the
       default path is /usr/lib/ipf/IPFILTER.LICENCE. If the Solaris operating
       environment has been installed anywhere other than the default,	modify
       the given path to access the file at the installed location.

DIAGNOSTICS
       Arguably,  the  -W and -R operations should set the locking and, rather
       than undo it, restore it to what it was previously.

       Fragment table information is currently not saved.
