It’s more that MacKeeper installs itself like a Mac Adobe product (or regular Windows software). It sprays itself all over the file system and wriggles into the weirdest of places making it nigh impossible to uninstall completely.

While firewalls and routers can be the same, neither has to be part of the other. Standalone firewalls are becoming less common these days but standalone routers are still very much a thing. Most layer 3 switches are just routing, not firewalling, likewise for internet backbone routers.

yeah sorry, i meant in the context of a NAT router.

by default a NAT router will drop incoming connections, because it has no idea where to point them, which is the firewally choice.

not an amazing thing in any way, except for home users who don't know poo poo. NAT really saved the world a ton of hurt there IMO, you mostly have to attack browsers now instead of people's publicly accessible, unpatched RDP ports. because i'm sure we all know if every ip was public, consumer routers would just blindly forward everything by default :v:

e: and yeah, DMZ on consumer routers is a big lol of a misnomer.

Is there any on-modification antivirus for macOS that can scan by file signature only and doesn’t just scan downloads? As far as I know, XProtect, the built-in one, only runs on files tagged as downloaded. I just want XProtect but for any files that get modified, regardless of supposed origin.

I tried modifying clamav from MacPorts to watch /Users, but it pegs an entire core of my CPU constantly due to being a giant hack.

Biggest fight is killing the last of our HTTP APIs and getting rid of FTP.

1803 has been out of support for 5 months, which means your computers possibly haven't received security updates since November 2019 (except for Enterprise versions, which get support till November 2020)

Yep. Enterprise. Apparently our desktop team is fighting to upgrade, but I don't know to what (hopefully not 1809) and I don't know how that's going.

Other question: Is there any reason an API would not use OAuth over the internet other than "because it's hard"?

We went to 1809. It doesn't really matter which one you pick, they are all bug-ridden festering poo poo garbage.

I've found so many bugs. Many of them aren't huge but they just keep adding up. Like Windows disabling WOL if you shut down from the login screen, but keeping WOL available when you shut down while logged in. Leaving EXCLUSIVE WRITE LOCKS OPEN over SMB after logoff, sending print jobs as Letter despite EVERYTHING set to A4 default EVERYWHERE, etc. etc.

Just go to the absolute latest, it will have fucktons of bugs, but who cares anymore.

The idea originated in television commercials for Alpo brand dog food; actor Lorne Greene would tout the benefits of the dog food, and then would say it's so good that he feeds it to his own dogs. In 1988, Microsoft manager Paul Maritz sent Brian Valentine, test manager for Microsoft LAN Manager, an email titled "Eating our own Dogfood" challenging him to increase internal usage of the product.

So far as I know, SMB doesn't do file locking at all, it only has something it calls locking which is cache control?
Which is annoying, because it means that Windows 10 doesn't work with NFS locking the way every single other NFS client implementation has since XP, where NetworkLanManager is just a thing you enable if you need it and bob's your uncle.

In this case, Windows places a DENY_ALL lock on the ntuser.dat during logoff and holds it forever. We _require_ roaming profiles and due to the way computer pools work, the same user may then log on on a different PC and get a temporary profile since ntuser.dat can't be accessed due to the lock held from the previous computer.

The "solution" is a logoff script of Start-Sleep 10. The lock is then released.

Locking on SMB is even worse than on NFS. A client can request a lock on a file, then go offline for a few months, and expect that nobody else has modified the file in the meantime.

We have of course disabled CSC completely because that thing is a data destroyer.

There's about a hundred places you can stick a UNC path and have windows try to connect to it, "have to con" is exaggerating the complexity slightly

(It may prove difficult to exploit but not for this reason)
