After all, DOSBox is not really designed to run MS-DOS, but its own DOS-like thing, and there must be a million small details that you can use to distinguish it from MS-DOS, if you really wanted to. I mean, the default filesystem is not even FAT... _Even_ if you run the MS-DOS kernel in DOSBox, the builtin DOS literally leaks through in many places (e.g. many API services still available instead of crashing), with only some of the more recent forks even trying to hide it. | | |

| ▲ | bombcar an hour ago | parent [-] | | I encountered this and hadn’t realized that DOSBox’s main goal was to play games - and that lots of “non game things” didn’t work. But DOSbox-X covered some; I ended up running DOS 5 in VMware. |

| ▲ | rwmj 3 hours ago | parent | prev [-] | | Testing if you're running under virtualization or emulation is a whole thing. We wrote virt-what to do this for virt and containers. It could do emulators as well if someone was motivated enough. It's basically a giant shell script. https://people.redhat.com/~rjones/virt-what/ There's also an adversarial aspect to this. Some emulators try to avoid detection and a lot of software tries to detect if it's running under virt for various reasons, eg. to stop cheating in games or stop reverse-engineering. (virt-what is deliberately not adversarial, it's very easy to "trick" it if you wanted to do that) | | |
| ▲ | tombert 3 hours ago | parent [-] | | Makes sense; when I was doing WGU they explicitly forbid virtual machines, which makes enough sense since if you're in a VM they can't see your full screen. It wouldn't surprise me if nowadays they have some sort of software detector to see if you're in a VM. | | |
| ▲ | eek2121 an hour ago | parent | next [-] | | There are detectors for VMs, and modifications to allow VMs to evade those detectors. It's an arms race. Example: There is (was? I don't actively follow the community) a patch set for a particular piece of VM software that made it undetectable to anti-cheat in games. While I don't use said software (I have a casual interest in it only...would be nice to get more games working on Linux), I have to disclose that I'm against anti-cheat mechanisms. I'm a software engineer, and I've worked on a few smaller games, and know the overall structure of bigger ones, and I don't think I've ever seen a game use good practices in multiplayer. Instead, they usually rely on client side code and lean on anti-cheat software to stop cheaters. | |

| ▲ | tombert 3 hours ago | parent [-] | | Sorry, Western Governors University. It's an online school. When taking a test they have a proctor that's watching you on a webcam, and they make you pan the webcam around the room to ensure that there's no obvious way to cheat, and they make you share your screen to ensure you only have a browser running. | | |
| ▲ | ButlerianJihad an hour ago | parent | next [-] | | When I took final exams or industry certifications, I reported in-person to the Testing Center at community college. The center is custom built for secure proctoring exams. You check in with ID, you stash your watch, phone and wallet in a locker, and you use a secure computer in a monitored quiet room. It’s perfect for all parties, and doesn’t intrude on your personal living space or devices. | |

Well that level of intrusiveness would just make me come up with something overly complicated just so I could prove that I could cheat if I wanted. | | |
| ▲ | bombcar an hour ago | parent [-] | | The proctors are bored college students or similar - you don’t have to do much to defeat it. They just want to make it difficult enough to catch most. |
