While debugging some network packet loss I stumbled over a blog post from 2013: Dropwatch to see where the packets are dropped in kernel stack. And another one: Using netstat and dropwatch to observe packet loss on Linux servers. I wanted to try it, but unfortunately fedorahosted.org where it was hosted previously is history since March 1st, 2017.
My favorite distributions and build systems didn’t have dropwatch as package or still used the old addresses so I looked for some clones at GitHub, got the E-Mail address of what appeared to be the maintainer and got in contact. I got a friendly reply and – good news everyone – the project is still maintained and moved to: git.infradead.org/users/nhorman/dropwatch.git …
Hope this helps someone, maybe when this page hits the search engines. ;-)
