HabrУправление ядрами ЦПУ при обработке сетевого трафикаПривет, Хабр! Не так давно столкнулся с задачей разработки альтернативного решения для ограничения сетевого трафика. Такая задача возникла в рамках разработки системы лицензирования для продукта класса NGFW (Next Generation Firewall). Используя такую систему ограничений можно было бы предусмотреть несколько видов лицензий на коммерческое использование продукта, где в зависимости от уровня приобретенной лицензии можно было бы предоставлять полную, либо урезанную функциональность продукта в части его производительности. В этой статье хочу поделиться опытом решения данной задачи.<a href="https://habr.com/ru/articles/857986/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://habr.com/ru/articles/857986/</a><a href="https://zhub.link/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> <a href="https://zhub.link/tags/%D1%81%D0%B5%D1%82%D0%B5%D0%B2%D1%8B%D0%B5_%D1%82%D0%B5%D1%85%D0%BD%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D0%B8" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#сетевые_технологии</a> <a href="https://zhub.link/tags/ethtool" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ethtool</a> <a href="https://zhub.link/tags/ratelimit" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ratelimit</a> <a href="https://zhub.link/tags/%D0%BE%D0%B3%D1%80%D0%B0%D0%BD%D0%B8%D1%87%D0%B5%D0%BD%D0%B8%D0%B5_%D1%82%D1%80%D0%B0%D1%84%D0%B8%D0%BA%D0%B0" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ограничение_трафика</a> <a href="https://zhub.link/tags/nc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nc</a> <a href="https://zhub.link/tags/highload" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#highload</a> <a href="https://zhub.link/tags/%D1%81%D0%B5%D1%82%D0%B5%D0%B2%D1%8B%D0%B5_%D0%BA%D0%B0%D1%80%D1%82%D1%8B" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#сетевые_карты</a> <a href="https://zhub.link/tags/mellanox" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mellanox</a> <a href="https://zhub.link/tags/rss" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rss</a>

Tangerine PulsarHey, can anybody linuxy-networky confirm something for me? I've got an Ubuntu server that i built relatively recently, when i build a new desktop the server gets the guts of the old desktop as a sort of hand me down upgrade.I use netdata to monitor and when a lot of the docker containers kick off at the same time I overrun the skb fifo ring buffer. So there a lot of retransmits and general inefficiency I'd like to tune the system to handle like I have beforeIn the past I've used ethtool with -g to see the current and max values, and in the past I've always had some headroom, so I'd increase the size a little with -G until the errors were rare or gone, trying not to eat up all my headroom and set it to the max size blindly because that comes with it's own penalties But when i try this on this build, I get InvalidError Operation Not SupportedI've got two ideas and i hate them both. Either a) the driver doesn't support getting or setting those values and I can try to find a different driver that works or change it to a different nic. b) systemd has hijacked this corner of what i used to know on Jammy Jellyfish and there's some new way to do things or c) something else entirely that isn't apparent to meAnyone got any ideas? <a href="https://octodon.social/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> <a href="https://octodon.social/tags/ubuntu" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ubuntu</a> <a href="https://octodon.social/tags/server" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#server</a> <a href="https://octodon.social/tags/networking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#networking</a> <a href="https://octodon.social/tags/homelab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#homelab</a> <a href="https://octodon.social/tags/nas" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nas</a> <a href="https://octodon.social/tags/ethtool" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ethtool</a> (i wonder if anyone has ever hashtagged that before)
