uruk-save(8) SYSTEM ADMINISTRATION uruk-save(8)
NAME
uruk-save - save uruk rc configuration in iptables-save-style format
SYNOPSIS
uruk-save [-6]
OPTIONS
-6
Don't save iptables rules but save ip6tables rules, for IPv6 filter-
ing.
DESCRIPTION
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
or
# 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.
WARNING
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 con-
tents 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.
