iputil is too pessimistic about whether common Unixish commands to get IP addresses will work on some random Unix. There are several command variants, but not many. It should just try all the possibilities in some sensible order, rather than trying to detect the exact platform.

See #1988

I added this line to _platform_map in iputil.py and it works:

"dragonfly3": "bsd",

The problem with this is that, when DragonFly? 4 comes out, it will break. The OS recognition should be done by prefix substring matching instead. Any OS name that begins with "openbsd" or "netbsd" or "freebsd" or "dragonfly" is a BSD, regardless of the version number.

Here's a list of all tickets about "iputil":

https://tahoe-lafs.org/trac/tahoe-lafs/query?status=!closed&keywords=~iputil

Hm, we need to open a new ticket for Daira's suggestion from #1918, to try invoking ifconfig (and then maybe route.exe?) regardless of platform.

  • Milestone changed from soon to 1.11.0
  • Resolution set to fixed
  • Status changed from assigned to closed

iputil on trunk no longer distinguishes between Unix variants, which fixes this bug.
