uruk-save - save uruk rc configuration in iptables-save-style format


uruk-save [-6]



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 fails.
