DESCRIPTION
iptables-restore
and
ip6tables-restore
are used to restore IP and IPv6 Tables from data specified on STDIN or in
file. Use I/O redirection provided by your shell to read from a file or
specify file as an argument.
- -c, --counters
-
restore the values of all packet and byte counters
- -h, --help
-
Print a short option summary.
- -n, --noflush
-
don't flush the previous contents of the table. If not specified,
both commands flush (delete) all previous contents of the respective table.
- -t, --test
-
Only parse and construct the ruleset, but do not commit it.
- -v, --verbose
-
Print additional debug info during ruleset processing.
- -V, --version
-
Print the program version number.
- -w, --wait [seconds]
-
Wait for the xtables lock.
To prevent multiple instances of the program from running concurrently,
an attempt will be made to obtain an exclusive lock at launch. By default,
the program will exit if the lock cannot be obtained. This option will
make the program wait (indefinitely or for optional seconds) until
the exclusive lock can be obtained.
- -W, --wait-interval microseconds
-
Interval to wait per each iteration.
When running latency sensitive applications, waiting for the xtables lock
for extended durations may not be acceptable. This option will make each
iteration take the amount of time specified. The default interval is
1 second. This option only works with -w.
- -M, --modprobe modprobe_program
-
Specify the path to the modprobe program. By default, iptables-restore will
inspect /proc/sys/kernel/modprobe to determine the executable's path.
- -T, --table name
-
Restore only the named table even if the input stream contains other ones.
