trippy VS duf

You are right that showing packet loss for intermediate hops is a frequent source of confusion.

Rather than leave it out, I added a status column which shows different statuses for intermediate hops (blue if the hop responds to less than 100% of probes and brown if it responds to 0%) vs the target hop (amber and red).

Where this breaks down is when dealing with ECMP for UDP & TCP tracing, as a given hop (ttl) may represent the target for a given round of tracing but not for the next. The mistake, imho, is to associate _any_ data with a hop (ttl) rather than the hop in the context of a tracing flow.

That is why Trippy had a number of features aimed at helping with ECMP, such as Paris and Dublin tracing, and the ability to filter tracing by unique flow id. I've covered these quite a bit in the 0.8.0 [0] and 0.9.0 [1] release notes if you want to know more.

Tracing flows: breakdown complex UDP/TCP ECMP traces into individual flows (i.e. common network path); render a chart of flows in GraphViz DOT format (example)

u/queiss_ the 0.8.0 release note has a section covering this, but the TL;DR is:

Not sure these are really popular, but I cannot resist advertising a few utilities written in Go that I regularly use in my daily workflow:

- gdu: a NCDU clone, much faster on SSD mounts [1]

- duf: a `df` clone with a nicer interface [2]

- massren: a `vidir` clone (simpler to use but with fewer options) [3]

- gotop: a `top` clone [4]

- micro: a nice TUI editor [5]

Building this kind of tools in Go makes sense, as the executables are statically compiled and are thus easy to install on remote servers.

Somewhat related - `duf` is "a better `df` alternative":

I'm normally using duf but this looks pretty neat.

Otherwise the last option is to get the deb/appimage files from their official git repos or website, like for my use cases, MongoDB Compass (which was not officially maintained on flatpak) or duf (not available in Ubuntu repos)

duf

What cool CLI tools do you know, that are do something faster than regular commands, and do something useful? For example: https://github.com/muesli/duf.

duf - Disk Usage/Free Utility - a better 'df' alternative.
