I think this is an excellent post, because you demonstrate an applied use of a bunch of excellent *nix tools, combined with a presentation of the mental model that helped you put it all together.

I am largely self taught, and I didn't touch C/C++ for a long time, so there's a lot of stuff people might take for granted (like the use of ldd), which for a long time I had never encountered.

Thank you for the kind words! Glad to hear you enjoyed it.

Your email is nowhere to be found, so it's impossible to email you about typos or bugs. Typos in this case.

Anyways search for:

Thus, it is imperative to avoid giving these containers running old software no access to the network

and remove the "no" I suppose? I might be wrong. Only one 'no' there, so it should be gone, afaik.

You're right, I don't post my email address on my blog, and yet it's widely available and discoverable (which leads to spam, so...). That said, you can find me on Twitter and LinkedIn, and send me a private message there.

Public comments on HN also work. :-)

Back to your original point:

You're absolutely right; that's a double negative—that "no" should either be dropped or replaced with "any". I'll fix that in a bit.

Thanks again for your careful reading and letting me know!

:) glad to be of help. Keep on producing great things.

Just wanted to let you know that I fixed this (and a few other issues I found upon re-reading my post for the Nth time).

Thanks again for your help!
