[08:31] <LocutusOfBorg> hello, looks like bos2 has a lot to clean today...
[08:33] <tomwardill> LocutusOfBorg: we're looking at it, it's failed to respond to a simple reset
[08:34] <LocutusOfBorg> thanks!
[09:28] <LocutusOfBorg> restarting bos02 worked, but lots of builds are failing with no logs now...

[09:29] <LocutusOfBorg> and so on
[09:37] <tomwardill> it's looking like a cloud/network issue, no fix we can try seems to stick
[17:04] <dkg> is there some reason that the ssh daemon on git.launchpad.net offers only an "ssh-rsa" host key?  that algorithm is dependent on SHA1, iiuc.  I've searched for info about it, but couldn't find anything.  I opened https://answers.launchpad.net/launchpad/+question/693449 to see if i could get more info that way
[17:05] <dkg> if there's some better way for me to push on it, please let me know!
[17:40] <cjwatson> dkg: Linked to a somewhat related bug, thanks
[17:41] <cjwatson> dkg: As is often the case with issues with our SSH endpoints, it needs some work in Twisted.  We've made quite a few contributions there over the last couple of years, and it looks as though we'll need to make more
[17:42] <dkg> cjwatson: thanks for the followup
[17:43] <cjwatson> Or at least I think it does, hmm
[17:44] <cjwatson> This stuff is a bit, err, twisted
[17:44] <dkg> no kidding -- it's a lot to keep track of, and i didn't even realize that i was asking for a software change
[17:46] <cjwatson> Ah yes, it does need Twisted work
[17:46] <cjwatson>         if keyType == "RSA":
[17:46] <cjwatson>             sig = self._keyObject.sign(data, padding.PKCS1v15(), hashes.SHA1())
[17:46] <cjwatson>             ret = common.NS(sig)
[17:46] <cjwatson> (twisted.conch.ssh.keys.Key.sign)
[17:47] <dkg> if you open a bug report about this with twisted, i'd be curious to see it
[17:48] <cjwatson> Given the maintenance of Twisted's SSH code, I'm more likely to open a PR :)
[17:48] <dkg> that too ☺
[17:48] <cjwatson> However there is the additional complexity that Twisted upstream is now Python 3-only
[17:48] <cjwatson> So for the time being even if I do get stuff in there we'd have to backport it
[19:52] <teward> cjwatson: is the SSH endpoint on git.l.n forcing SHA1 or have you adjusted it to accept non-SHA1 hashes?  I ask this because hashes > SHA1 are available with ssh-rsa keys (yes I looked that up) but it needs server-side enforcement last I checked.
[19:52] <teward> ... nevermind I see the fact that it's Twisted related >.<
[19:52] <teward> twisted is annoying :P
[20:03] <cjwatson> teward: twisted just hasn't implemented the other host key algorithms from RFC8332.  Likely no big deal to do
