uruk-save — save uruk rc configuration in iptables-save-style format
Don't save iptables rules but save
ip6tables rules, for IPv6 filtering.
uruk-save saves the IPv4 rules (for all of the filter, raw, mangle and nat
tables) in /etc/uruk/rc in iptables-save(5)-style format, without invoking
iptables(8). If the -6 option is given, the IPv6 rules (if any) in
/etc/uruk/rc are saved, in ip6tables-save(5)-style format. It prints output
to stdout; suggested invocation therefore is
# uruk-save > /var/lib/uruk/iptables/active
# uruk-save -6 > /var/lib/uruk/ip6tables/active
. This script is useful if you don't like the default behaviour of the uruk
init script, and would like it to load the current uruk rc file instead of the
current active file. Please note: generally you don't need to invoke this
script manually: the script urukctl which comes with uruk is suitable for most
cases, it invokes uruk-save if needed.
Just as uruk, in order to keep the uruk-save script small and simple, the
script does very little error handling. It does not check the contents of the
rc file in any way before executing it. When your rc file contains bogus
stuff, uruk-save will very likely behave in unexpected ways. Caveat emptor.
Things will likely break if you do very fancy stuff in an rc hook file. If
your rc file is in verbose mode (i.e. it features set -x) or in no-act
mode (i.e. it features a hardcoded iptables='echo iptables'), uruk-save
uruk(8), uruk-rc(5) .
