IPFS(8) System Manager's Manual 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 in-
terrupted.
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, ip-
state.ipf and ipnat.ipf, stored in the /var/db/ipf directory un-
less otherwise specified by the -d option. The state tables are
locked at the beginning of this operation and unlocked once com-
plete.
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 informa-
tion is currently not saved.
