letsenctrypt certbot-auto – finding what certificates are there and which apache configurations use them

Posted by jpluimers on 2016/10/13

IRC #letsencrypt-dev today:

wiert

Is there any way for `certbot-auto` to show for which domains/apache-configs it has certificates?

pdeee

wiert, we actually made a ticket for 0.10.0 to do that

https://github.com/certbot/certbot/issues/3615

in the mean time, your imperfect options are:

for file in /etc/letsencrypt/live/*/fullchain.pem ; do echo -n $file ;  openssl x509 -text -noout -in $file | grep DNS; done

for installation in Apache configs, you can follow that with:

grep /etc/letsencrypt/live /etc/apache2/sites-enabled/*

wiert

@pdeee on OpenSuSE, the last statement should be

grep -r /etc/letsencrypt/live /etc/apache2/*

Differences between SFTP and “FTP over SSH” – Stack Overflow

Posted by jpluimers on 2016/10/13

As I will likely have to secure some external FTP sessions soon and the endpoints the current FTP connects to are vague in what they support:

Here is the difference:

  • SFTP (SSH file transfer protocol) is a protocol that provides file transfer and manipulation capabilities. It can work over any reliable data stream, but is typically used with SSH
  • “FTP over SSH” uses the regular old FTP protocol, but an SSH tunnel is placed between client and server.

Thanks Ilya Grigorik for sharing this a long while ago:

TCP and the lower bound of web performance… is a must watch talk on plumbing, history, and people behind TCP. Awesome.
