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 pre-
vented) 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 inter-
rupted.
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.
-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 recon-
figuration 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 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

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