Details

nethogs assumes a default interface of eth0. This is no longer useful in a systemd world. Is there anyway we can have it default to the currently [most (sic)] up interface? Pain in the ass to have to do `ip addr` to dig out the 'enp0s25' string which is my network card on today's computer.

Why should arch do this and not upstream? What is the "default" interface when a machine has 5 NICs?

I suggest you write an alias.

Also, nethogs is in [community]. Make assigning the bug to me tricky.

Right, what he said.

There is no way to hardcode a guess as to what your interfaces will be. I see two possible solutions:

1) Remove the default. Make nethogs error when there is no specified interface. Aka, BOFH solution.
2) Make the default smarter. Since it can't guess which of your ifaces are being used, the default should display traffic for all of them.

You can fake the second with
nethogs $(ip -4 -6 -o a | cut -f 2 -d ' ')

Personally I don't want to write either of these today. I suggest you try requesting the feature upstream.

I will close this tomorrow-ish unless there is meaningful input, such as an upstream feature request to link.

Checked the upstream CVS, they've added this feature three months ago. Request a new point release instead :-)
