Looking for second opinions on my answer for quality.
but also astounded that question was even asked xD
@FaheemMitha Spent today urgently putting together a time estimate for building an entire PKI solution for a client. Only problem was we hadn't finished the analysis and have no idea what kind of platform, or pretty much anything other than "make PKI happen". Which is about as useful as "build me a house" without specifying if it's a small shed or a skyscraper...
@FaheemMitha Not in so many words. Also not allowed to hit them. Although to be fair, the issue is that their owner wants to cut down the IT budget and everyone is scrambling to get their projects through the new budget. So I can see why it was urgent.
@FaheemMitha Our biggest contracts are government organizations. Apart from that, it's a mix between national and multinational. This particular client is national; it's the company that handles nuclear waste for all Swedish nuclear power stations, so they're owned by the companies that run the power stations.
@FaheemMitha They seem to be doing a good job of it. They have an entirely different set of security concerns than most of our clients - most clients worry about people getting into their systems, but these people worry about physical material getting out. And they have requirements like "storing documentation in a readable format for 100.000 years".
And yeah, I do mean it literally. The thought is that either the human race goes extinct, in which case there'll be nobody to keep updating the documentation, or it won't, in which case there needs to be processes for translating and converting to new formats and so on.
@FaheemMitha No - the thinking is that if the nuclear waste needs to be stored for 100k years, then there also needs to be documentation about what is in that storage that is usable for as long as the storage is needed
@FaheemMitha yeah, that is what makes it an interesting problem! The amount of stuff you need to consider, and putting processes in place to handle the stuff that you haven't thought of!
@FaheemMitha One obvious thing is translation. We can understand texts written 250 years ago, mostly. But texts written 500 years ago are hard for us. So if they want the documentation to be usable in the future, they will need to have procedures to update it.
Another thing is if the documentation is signed cryptographically, a signature that is now good enough that it can be used to verify the contents and know it's not been tampered with won't stay good enough. So they'll need procedures to re-sign documentation before the old signature is no longer reliable.
And, of course, conversion to new physical formats. We already can't read tapes from a few decades ago. And even if written down, paper doesn't last forever, nor does ink, nor does even stone.
So translation, re-signing, conversion - those are things that need to happen. Plus of course redundancy/resilience in case of e.g. fire, flood or something.
@FaheemMitha Yes, that's where the procedures come in... they'll need to have a review process that goes through all documents at specific intervals and updates them to whatever is currently needed.
of course, none of this will be my actual job, except to help with an API for signing docs
but it's really fun to talk to the people who work with this stuff
After 20 years in the business, it's easy to get a bit jaded, like nobody has any new problem ever... and then you find someone who has an entirely different set of issues and it makes life interesting again
I just bought a D-Link DWA-160 revision B2. Little did I know that this revision comes with a Ralink chipset. The main reason why I got DWA-160 is because I already have one and I'm pretty happy with it. I mainly use it on a Windows computer, but I know that it works in Ubuntu 12.04 LTS for examp...
@TinyGiant Ok. And this computer doesn't have a net connection? Does it have sources in it? If so, you can get a list of packages you need via apt. I think.
So I've been battling with my debian install lately, it doesn't have the firmware for either eth0 or wan0 NIC's. However, I got a firmware.zip file that I need to extract to /lib/firmware. The problem is, since I have no connection from the computer, I can't just apt-get what I want.
Here's my q...

It was working when I tested it last night on the laptop.
@TinyGiant definitely post a Q that way when you get this working it can benefit future readers (and us who can point them to it) in solving the same issues
@stéphane-chazelas and @terdon, Thanks for your feedback about unix.stackexchange.com/a/247055/139893 I updated (actually rewrote) the answer based on your feedback. Please review if you wish. Comments welcome. I really didn't want to mention GNU extensions because the examples are almost universal, and I don't think the GNU -r applies the questioner's situation. Does anyone know when the -exec ...+ syntax was introduced? I know it wasn't on on 4.1 BSD! :-)
Despite being a perl person, I often use things like find to feed a list of file names to a perl script. It's much more flexible. Unless you add a lot of complexity to the perl script.
it's also easier to test, unless you've added more complexity to the script to test. I can easily leave off the -exec so find will print the list.
sometimes of course its worth it—maybe the script can't tolerate the file list being split into multiple invocations, for example.
or the file selection criteria is complicated enough that it's easier to write it in perl
@Braiam: I got a live stick running and am installing a dual boot of Fedora 22. It recognizes the dongle right away, so it has to be a problem with the way I set up debian. I'm not going to post a question about it right now because I'm fairly certain it has to do with the netinstall like you thought. Once I have some time I am going to set up a clean netinstall and test the steps that we tried previously.
I'm sure there can be a good question made out of this, but I don't want any stupid modifications I've made to get in the way.
@Braiam Original question asks specifically about using the find command with perl. I included the find2perl option because the example was written in perl, and because of the relation to the find command, but find2perl doesn't directly call the find command, hence my reason for listing it last.
@Braiam When you said "questioning OP's logic not the answer" does "OP" refer to the author of the original question or the author of the answer? I thought you were questioning the structure of the answer, but maybe you meant questioning the logic of the original questioner?
As far as easier/faster, I think easier is an opinion-call toss-up. Faster to implement the same. But I seem to remember reading years ago that find2perl code can execute faster. Do you know or have experience with it?
Vesa K's version of Ryan Novosielski's answer works for me, but the lines are in:
/etc/pam.d/sshd
not:
/etc/pam.d/login
In my case, I just want UID 1000 under Ubuntu 14.04 LTS to be allowed to login via SSH.

I tried Ryan's rule today and found out that Gils's and Ryan's answers bot have success/default rules "reversed", nologin blocks only nx-group. This is how I implemented this rule (nx group is not blocked by nologin).

so what's the correct incantation here? What's wrong with the others? I haven't practiced pam much and it's been a long time.

I have a friend who has got a computer that is not connected to the Internet. Is there any way to install software offline easily?
