Thank you for the explanations. Very kind :)
So I let everything as it was, except that I decided to allow SSH. Again, I have some questions.
I managed to get Jailkit running. However I have some security concerns.
1) Jailkit CHROOT is more secure than "NONE" CHROOT?
It's seems so. Is it?
Then, what makes me fear.
After logging in with a Jailkit account, I can see some files and folders which should not be visible/editable (I guess). I have:
and all files in there seem secure to me?
is empty, seems fine too?
and files in there (null, tty & urandom), what is this?
fear! should this dir be there? And it's content:
makes sense :)
again, I have no idea what the files in there are...
with subfolders /bin, /lib, /sbin & share - seems fine?
with a folder /run - this seems to be for MySQL?
I know this is a lot of stuff.... :)
Thank you, once again.
