uruk-save(8)

💾 uruk-save — the girlies' guide to uruk-save(8) 💾

okay so bestie, welcome to the SYSTEM ADMINISTRATION section of the manual, and today's main character is uruk-save. she's little, she's simple, she saves your uruk rc config in that classic iptables-save-style format. let's get into it 🫶

---

✨ NAME ✨

uruk-save — save uruk rc configuration in iptables-save-style format. that's it. that's the whole job. no cap 💅

---

🌸 SYNOPSIS 🌸

uruk-save [-6]

---

🎀 OPTIONS 🎀

• -6 — bestie, do not save the iptables rules. instead save the ip6tables rules, for IPv6 filtering. it's giving "we're doing the v6 thing now" ✨

---

🦋 DESCRIPTION 🦋

so here's the tea ☕: uruk-save saves the IPv4 rules — and yes, that's all of the filter, raw, mangle and nat tables — into /etc/uruk/rc, in iptables-save(5)-style format. and the iconic part? it does this without invoking iptables(8). we simply don't need him 💅

if you pass the -6 option, then the IPv6 rules (if any, bestie — if any) in /etc/uruk/rc get saved instead, in ip6tables-save(5)-style format. slay.

it prints output to stdout, so the suggested invocation is literally:

# 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 you'd like it to load the current uruk rc file instead of the current active file. so valid. so real.

please note: generally you don't need to invoke this script manually — like, at all. the script urukctl, which comes with uruk, is suitable for most cases, and it invokes uruk-save if needed. let her cook 👑

💀 WARNING 💀

just as with 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. that's the vibe check and it did not pass 🙈
