Two wrappers exist to make this easier: Comcast (a Go-based tc wrapper) and tcconfig (a Python-based alternative). Daniel Dib used tcconfig to simulate WAN link behavior on VMware vSphere, providing a more approachable way to test network impairment scenarios. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What Python tool can I use to configure Linux tc (traffic control) without dealing with the complex tc CLI? tcconfig is a Python-based wrapper around the Linux tc (traffic control) command that makes it easier to simulate WAN link impairment. It abstracts the complex tc CLI syntax into a more approachable interface. An alternative wrapper called Comcast exists but is not Python-based. tcconfig has been used to simulate WAN link behavior on VMware vSphere. _Engineers testing network impairment scenarios track tools like tcconfig on daily.dev._ ## Similar posts on daily.dev - [Networking Aspects of Running VMs in Containers « ipSpace.net blog](https://daily.dev/posts/networking-aspects-of-running-vms-in-containers-ipspace-net-blog-gttjndloc) · ipSpace.net Blog · 0 upvotes · 0 comments - [Command and Control & Tunnelling via ICMP](https://daily.dev/posts/command-and-control-tunnelling-via-icmp-gocxfoecc) · InfoSec Write-ups · 0 upvotes · 0 comments - [Technology Short Take 193](https://daily.dev/posts/technology-short-take-193-rgvb2tcqy) · Scott's Weblog · 0 upvotes · 0 comments - [I used Tailscale's subnet routing to make my entire home lab feel like it's on my laptop](https://daily.dev/posts/i-used-tailscale-s-subnet-routing-to-make-my-entire-home-lab-feel-like-it-s-on-my-laptop-w9a6iutxx) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/configuring-linux-traffic-control-in-a-sane-way-ipspace-net-blog-a0pi2eeao) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Configuring Linux Traffic Control in a Sane Way « ipSpace.net blog","url":"https://daily.dev/posts/configuring-linux-traffic-control-in-a-sane-way-ipspace-net-blog-a0pi2eeao","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/configuring-linux-traffic-control-in-a-sane-way-ipspace-net-blog-a0pi2eeao"},"datePublished":"2026-08-11T08:55:50.539Z","dateModified":"2026-08-11T09:27:55.771Z","description":"Linux traffic control (tc) can simulate WAN link impairment, but its CLI is notoriously difficult to use.
