samenome"Don't use shorewall anymore, it's old" my stupid brain said. And who wants to be 'old'? Not me. No. I am hip, chic, sprightly-brained. I also live a very happy rich fantasy existence, keep that pin away from my bubble!DuckDuckGo: 'nftables replacement for shorewall' gets: "Just accept that Firewalld is a major player, and that iptables is on its way out with nftables being more robust and consistent. And nftables is the default Firewalld back end. Firewalld is good once you get used to what it's doing. And it's the default on Fedora/CentOS/RHEL and SUSE/openSUSE Leap/Tumbleweed. "I am always using <a href="https://aus.social/tags/Debian" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Debian</a>, (because, ahem, old? I'd dare not say) including on this firewall box. But, there's a firewalld package. Probably best to go with the flow ....So I install firewalld, then muck about with dnsmasq, then turn back to fiirewalld, which seems enabled without me asking consciously asking for it (?) oh well ...Then I get to: Machine: A zone called 'work' exists. Me: nnah, not here in my shed it doesn't. <a href="https://aus.social/tags/firewall" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#firewall</a>-cmd --delete-zone=work --permanent Machine: Error: BUILTIN_ZONE: 'work' is built-in zoneWhat!? Say the fuck WHAT? "work"??? What fresh hell is this? Am I not allowed to be away from work even here at my shed with the magpies and roos?Christ on a bike. Well I'll just get my bigger stick, and do: <a href="https://aus.social/tags/rm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rm</a> /etc/firewalld/zones/work* and restart firewalld. ... It is back ... 🤐 Machine: Error: BUILTIN_ZONE: 'work' is built-in zone Oh. ComeTheFuckON!<a href="https://aus.social/tags/firewalld" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#firewalld</a>, unless something changes my mind in the night, you are headed for the bin in the morning. And some unasked-for advice from me to the <a href="https://aus.social/tags/firewalld" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#firewalld</a> people: You MIGHT, just might, have permanent built-ins for 'drop' and 'bridge', ... perhaps. But 'work'? Fuck off to the place with the fuckoff sign, read it carefully, then fuck off further, yes and your friends too. Example zones? fine. Recipes about common 'internal'/'dmz'/'external' arrangements? also fine. Helpful in fact. Demanding that I have a "work" zone???

samurroOne thing which came to my mind recently, why are both <a href="https://fosstodon.org/tags/pfsense" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pfsense</a> and <a href="https://fosstodon.org/tags/opnsense" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opnsense</a> based on <a href="https://fosstodon.org/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeBSD</a> instead of <a href="https://fosstodon.org/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenBSD</a>? If the latter is aimed at <a href="https://fosstodon.org/tags/security" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#security</a> it would be the best bet to use for such a critical system as a router. Are there any real technical reasons for it not being the base of such popular <a href="https://fosstodon.org/tags/router" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#router</a> operating systems?

Pierre Boudes[same in en]. I'm going to buy new data center switches. Until now, I used refurbished Arista switches (which work perfectly), but this is to distribute the network to about twenty higher education institutions; I can't afford the worn-out stuff. What brand would you use? Are there any European manufacturers? We'll need 100 Gb and plenty of 10/25 Gb ports. I plan on using generic optical transceivers, though. <a href="https://universites.social/tags/networking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#networking</a> <a href="https://universites.social/tags/switch" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#switch</a> <a href="https://universites.social/tags/datacenter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#datacenter</a>

Jeremiah LeeMy building has fiber to each apartment and CAT5e within apartments. There is a "Fiber Ethernet Media Converter: 10/100/1000Base T/TX to 1000Base FX Bridging Converter".The UniFi Cloud Gateway Fiber gateway has a 10G SFP+ WAN port. <a href="https://techspecs.ui.com/unifi/cloud-gateways/ucg-fiber" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://techspecs.ui.com/unifi/cloud-gateways/ucg-fiber</a>Can this port be used to convert the fiber without needing a separate external device?I assume I would need to buy a fiber SFP+ module.

samurroWe have a <a href="https://fosstodon.org/tags/DNS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DNS</a> setup in our company with one hidden primary and one internal primary <a href="https://fosstodon.org/tags/dnsserver" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#dnsserver</a>. These servers use external and internal views. I am just quoting our documentation here. My question is, if our internal DNS server is not reachable for whatever reason, is there any downsides to use the hidden primary as a fallback? Or do we need to establish redundancy for DNS in some other form? <a href="https://fosstodon.org/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> <a href="https://fosstodon.org/tags/networking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#networking</a> <a href="https://fosstodon.org/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SysAdmin</a>

hyperrealIf I can get my OPNsense device setup again, I can have a DMZ on my home network, migrate my public web services to my homelab, and save money by eliminating my main VPS.
