Tech note for certbot!

Did some testing this morning on the new certs and realised that things were not working in firefox and at one point I think I saw an erro in chrome!
Problem was fire fox needed both www and non www versions of the site name. Re issuing the cert sorted this in no time!

This is how the process worked out…!

sudo certbot --nginx

Just a quick shout out …. So one of the things that is some times talked about is the problem of the “non heterogeneous” or homogenous networking environment. The illusion that choosing the market dominant product (because everyone else buys it) is the right thing to do …. Anyhow it seems that Cisco is in a bit of bother due to its some what hated buggy protocol CDP. If your a cisco nerd and haven’t caught up on this it might be time to do a bit of serious patching!

Have a look at this wired article

Stay safe on the Interwebs!
