IPTABLES-APPLY
Section: iptables 1.8.13 (8) Updated: Index
Return to Main Contents
NAME
iptable-apply - a safer way to update iptables remotely
SYNOPSIS
iptables-apply [- hV] [ -t timeout] [ -w savefile] {[ rulesfile]-c [runcmd]}
DESCRIPTION
iptables-apply will try to apply a new rulesfile (as output by
iptable-save, read by iptable-restore) or run a command to configure
iptables and then prompt the user whether the changes are okay. If the
new iptables rules cut the existing connection, the user will not be
able to answer affirmatively. In this case, the script rolls back to
the previous working iptables rules after the timeout expires.
Successfully applied rules can also be written to savefile and later used
to roll back to this state. This can be used to implement a store last good
configuration mechanism when experimenting with an iptables setup script:
iptable-apply -w /etc/network/iptables.up.rules -c /etc/network/iptables.up.run
When called as ip6tables-apply, the script will use
ip6tables-save/-restore and IPv6 default values instead. Default
value for rulesfile is '/etc/network/iptables.up.rules'.
OPTIONS
- -t seconds, --timeout seconds
-
Sets the timeout in seconds after which the script will roll back
to the previous ruleset (default: 10).
- -w savefile, --write savefile
-
Specify the savefile where successfully applied rules will be written to
(default if empty string is given: /etc/network/iptables.up.rules).
- -c runcmd, --command runcmd
-
Run command runcmd to configure iptables instead of applying a rulesfile
(default: /etc/network/iptables.up.run).
- -h, --help
-
Display usage information.
- -V, --version
-
