Aihe: Re: [DNG] BAD sig with Devuan Jessie 1.0.0-RC
Thanks, Rick Moen (in the other short reply, where he suggested pasting
somewhere, what? the trace?, probably not... But the hashes *are* there
in my previous mail, and thanks to PGP they are verifiably exactly what
I sent...)... But I'll see to the missing information. I'm now starting
more serious work on this.

In the mail the moderators let through there is (I'll post that email at:

https://www.croatiafidelis.hr/foss/cap/cap-170423-devuan-iso-sig/
### --> non-existent at the time of writing this <-- ####

along with other stuff, more below on my plans)

And I'll post that now hours old trace above too (reading the network is
such slow work...).

et cetera...

What I reported is still the case (well it was half an hour or one hour
ago when I started writing this very email that you're reading)...

This is actual paste from terminal (I removed just what is before $):

I've got this trace:

a82af49c5c65aeb83e5cc4b136c38041d44121d029b3b662f7315008d87f30ac dump_170423_2102_g0n.pcap

for the above event.

I'll be working on this, whatever be the reason for the BAD sig on that hash,
that it be trivial forgetfulness or that it be MiTM deployed, because it is exactly
for reasons like this that I put together my: https://github.com/miroR/uncenz

If I don't break, it should be on:

https://www.croatiafidelis.hr/foss/cap/cap-170423-devuan-iso-sig/

(non-existent directory at the time of writing of this email, and it
will be not just a little bit of work...)

What are the reasons that I put together my uncenz? (Which, BTW it would
be great if a real programmer made it something more generally useable,
because my skills are too insufficient...)

E.g. if anybody used my uncenz to record those events that are now
undocumented, and I say they are undocumented because this:

Why I don't want to have Pöttersoft on mysystem
https://lists.dyne.org/lurker/message/20170417.151111.69a2f3e0.en.html

is just a say-so, even though by respectable author, that's not verifiably reported event...

But if somebody alerted me to record it with my uncenz, it would have
been documented for posterity... (Granted also that I would have been
available in time, which, sadly is just not always the case, I work
terribly slow...)

And if this PGP-signature failing is an attack or if it is a blunder, I
really don't know. But I also don't want anybody to think that my claims
are just mistakes of a user who is that badly incapable, I don't want
that either...

Pls., so I can try and start installing Devuan for real, can any of you
developers in charge PGP-sign an answer to this question of mine with
your PGP-key, so I can believe that I got genuine Devuan media? Pls. sign
your answer to the following question:

Is this media:

devuan_jessie_1.0.0-RC_amd64_DVD.iso

from:

https://files.devuan.org/devuan_jessie_rc/

correct if its hash is:

f4b0fc1fd3c7769055f4b611d8173a6a3be38eced0bcc72c65cc2fefa0914837 devuan_jessie_1.0.0-RC_amd64_DVD.iso

?

Thank you!

I'm also attaching the SHA256SUMS.asc SHA256SUMS from the new event
futher above (and they are the same ones as in my previous email!, just
this time gotten anew; however, they will be extractable from the trace
once I post it at the already mentioned, at the time of writing
inexistent url on CroatiaFidelis.hr), reported by the paste from my
terminal, and also which network trace, and the effemeral SSL-keys hash
like below:

a82af49c5c65aeb83e5cc4b136c38041d44121d029b3b662f7315008d87f30ac dump_170423_2102_g0n.pcap
f29ee5925bd400168b48cdcfef192be5d5d6ed9c90a80cde6c1a8591371be16d dump_170423_2102_g0n_SSLKEYLOGFILE.txt

(
but of course, I'm not attaching those, they will be on:
https://www.croatiafidelis.hr/foss/cap/cap-170423-devuan-iso-sig/
--at the time of writing inexistent--
if I don't break in the meantime, ermh... from mental stress ;-(
)

Thanks again if any of you devs in charge confirm that the SHA256 sum
that I downloaded is correct! And thanks for everybody's patience (of
which more will likely be needed)...
