Scott was the runner-up in the last Security.SE moderator election that only had one open slot. He has been a fantastic member of that community. Instead of nominating myself as I had intended to do the next run around, I'd like to throw my endorsement by behind @ScottPack. In both that community and here he has been a fantastic contributor and I think we'd really benefit from his election as a moderator.

comment Disk IO in Linux is slow (2MB/sec) while in Windows its fast (400MB/s)
Can you please post the actual output? Also, my first guess is some sort of horribly misconfigured driver, or lack of TRIM usage on the Linux side.

comment How to check/set linux’s “security level”?
@SvW Follow the link. The security level being talked about is a concrete concept in the kernel with very specific explanations about what each level does.

comment Something is burning in the server room; how can I quickly identify what it is?
Yeah, as a former firefighter, I wouldn't stay there without my gear. Even when a fire is out, we are trained to stay packed up because of the poisonous gasses. If I would call the pros, you should too!

@EEAA ... but that doesn't explain why the routing doesn't work for an outside host.

comment How to run selinux sanbdox with access to /dev/urandom
No, you'll have to copy the sandbox_t to another context name, bless the context to read /dev/urandom, and run your program in that new context.

comment Where can I find a list of IP addresses of hosting providers?
I don't know about a list of hosting AS systems, but I'd start with some regular expressions (/hosting/ seems to cut out a lot) and adding in some regular ones yourself. Just call a isSpamAS(number) script and add any systems you never want to see as you go.

Now you're making it more confusing. Are you limiting the folder size, or the traffic per day?

comment Mounting a USB Mass Storage Device in Debian
@user907560 At the outset, your question is indistinguishable from end-user support and doesn't provide the information we need to know that the flash drive works elsewhere. This further information helps a lot. +1.

comment Mounting a USB Mass Storage Device in Debian
This would be on-topic for SuperUser or Unix & Linux, but it doesn't fit here and since I can't discern whether those fires are wrong or really what you're asking about in regards to, "Without using the Internet" (which you're on), I'm not keen to migrate.

comment Debian package bigger than the source files
If an answer was correct, you should select the checkmark next to it. That indicates the problem has been solved. If you solved it, but no answers provided were helpful, then you should write your own and select that.

comment Debian package bigger than the source files
If a .git path is entering your package, you should rewrite the packaging scripts to ignore any unexpected ".*" files.

comment Privileges for ifconfig
@vonbrand That's an old view of Unix systems. In modern Linux, UID 0's power is only traditional as far as function goes. Capabilities are the defining matter, so any user can be given all or portions of that power. Similarly, a system can have a root / UID 0 user with no special privileges.
