Is this normal? I'm particularly concerned about port 445-the microsoft-ds service. *Puts on tinfoil hat.* I don't have any reason that I'm aware of to have open ports. I'm not a gamer, I don't connect anywhere remotely, and I don't remember doing anything that would open any ports.
Thanks for any advice! I'm sort of freaking out right now.

Samba (smbd/nmbd) are running by default, so those ports will be open. You can disable the service if you won't need it, or firewall the ports off with ufw.
Also, 631 is for cups (printing). You can also firewall that one off if you are not sharing a printer.
Habitual--I do have a router. Maybe that explains it?
I'm starting to be a little...interested...now. Gufw is crashing every second time I launch it and does not show up in my menu (Cinnamon). By "crashing" I mean that the gufw window shuts down suddenly. When I launch it after that everything is turned off. When I enable it "in" and "out" have no values. And then when I set them correctly, close the window, and launch it again, it crashes. And so on...

Fred:
Did you change the "Status" to On in gufw?
Does doing so change how gufw handles your changes?
If it is already enabled, then IDK what else it could be.

Fred I may not be the sharpest knife in the drawer, but it looks to me as if the firewall will not allow any incoming on your ports. Also, I run LMDE2 64 bit also and have had the same trouble with gufw.

I've never seen so many warnings from rkhunter in my life! I don't know what you guys think, but I'm getting outta here until I hear more! At least I have triple-boot. Back soon!
EDIT: I also can't log out. Hmmm....
EDIT2: I just booted into Kali and had a similar (though not identical) result. After running "rkhunter --propupd" the warnings were gone. I still don't trust it right now, though. Fortunately, my install of Betsy reconfigured to use Devuan is reporting clean.

Thanks Habitual. The only trouble is I'm afraid to boot back into that installation until I figure out what those warnings were about! I'd dismiss 'em as false positives if it weren't for:
(a). I run rkhunter a good bit and I've never seen anything like this before. I've definitely run it multiple times on this installation and it's always come back clean.
(b). My not being able to log out was also slightly suspicious.
I'm a tad worried now I've got a "friend" in my system.

One wishes that rkhunter would be a little more verbose about its warnings. A legitimate update could have changed all of those binaries and their database could just be a little behind the times.

Yeah, sorry, I started a new thread a few hours ago about this. I was just letting you know that the link you sent did not show any open ports.
But as far as rkhunter itself goes, I do believe that the trouble was my not running the --propupd just as you mentioned. If you want to look at that thread, it's http://forums.linuxmint.com/viewtopic.p ... 2&t=207441 I'll post there in a moment with /var/log/rkhunter.log
EDIT: Wait...what??? I was responding to a post by you that doesn't seem to be there.

and scan the router to see if anything is open.
If they are not, You won't need [g]ufw for the current situation.
See you Monday'ish Cobber.
Have a good weekend.
Same to you!
I'll check that link ASAP. Meanwhile, I do need a firewall of some sort since this is a lappy and I travel with it a good deal--or am I wrong? This means connecting to untrusted wifi's, unfortunately.
Edit: I've already used that link. All ports are closed, or so it says. Thanks!
