DESCRIPTION

31       The  ipfs  utility  enables  the  saving  of  state  information across
32       reboots. Specifically, the utility allows state information created for
33       NAT  entries  and  rules  using "keep state" to be locked (modification
34       prevented) and then saved to disk. Then, after a reboot, that  informa‐
35       tion  is  restored. The result of this state-saving is that connections
36       are not interrupted.
37

OPTIONS

39       The following options are supported:
40
41       -d    Change the default directory used with -R and -W options for sav‐
42             ing state information.
43
44
45       -n    Do  not  take  any action that would affect information stored in
46             the kernel or on disk.
47
48
49       -v    Provides a verbose description of ipfs activities.
50
51
52       -N    Operate on NAT information.
53
54
55       -S    Operate on filtering state information.
56
57
58       -u    Unlock state tables in the kernel.
59
60
61       -l    Lock state tables in the kernel.
62
63
64       -r    Read information in from the specified file and load it into  the
65             kernel.  This  requires  the  state  tables  to have already been
66             locked and does not change the lock once complete.
67
68
69       -w    Write information out to the specified file and from the  kernel.
70             This  requires  the  state tables to have already been locked and
71             does not change the lock once complete.
72
73
74       -R    Restores all saved state information, if  any,  from  two  files,
75             ipstate.ipf  and  ipnat.ipf, stored in the /var/db/ipf directory.
76             This directory can be changed  with  the  -d  option.  The  state
77             tables are locked at the beginning of this operation and unlocked
78             once complete.
79
80
81       -W    Saves in-kernel state information, if  any,  out  to  two  files,
82             ipstate.ipf  and  ipnat.ipf, stored in the /var/db/ipf directory.
83             This directory can be changed  with  the  -d  option.  The  state
84             tables are locked at the beginning of this operation and unlocked
85             once complete.

DIAGNOSTICS

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

121       Fragment table information is currently not saved.
