Re: Connection refused to Guix-hosted SSH

["dabbede@gmail.com" <dabbede@gmail.com>]

Hi all,

in the end I gave up... since my guix was not pulling anymore, I
suspected something more "serious" was happening than just a broken
ssh.
Then I've re-installed the whole system (it was a test system anyway,
not a big deal) and this time ssh works out of the box.
During installation, I've spotted one possible cause that could have
broken sshd in my first sistem: I did not select "Mozilla NSS
certificates" (which translates to package (specification->package
"nss-certs")) ).
I don't know if it is related, but the description says "To connect
through https"... probably not...
The other difference is that my first system was based on i686
(32bit), while the latter is x86_64 (64bit).

Whatever the reason, thank you all for the help.
I hope one day I'll be skilled enough to help others as well.

Regards
