2018-01-26 21:14:36 -0600 asked a question How to disable SSH root access in Fedora 27 using the Terminal?

I just executed the command "rkhunter --check" and there's a warning telling me to disable remote root access, also known as Secure Shell root login. I managed to do this in previous versions of Fedora by changing a line in the config file /var/log/rkhunter/rkhunter.log from "#PermitRootLogin" to "PermitRootLogin". As of now, this doesn't have any effect on the warning issued by rkhunter. So, is this a flaw in rkhunter or a change in the source code of Fedora? Any type of help that fixes this issue is highly appreciated.

RhythmBox never worked for me at all - so I added the RpmFusion-free repo and installed VLC Media Player. I would highly recommend this procedure and additionally, remove RhythmBox from your system to both free disk space and improve security - every unnecessary package will interfere with the overall security, stability and speed of the computer.

I know a similar issue, I can't install RevengeOS in my GNOME-Boxes, but I don't know how to print the error message - so I guess I'm screwed...

2018-01-25 09:15:22 -0600 asked a question My external hard disks corrupted my non-root user account

Greetings, y'all!

I connected my two external HDDs to my Fedora 27 machine and the result is terrible - first of all, it logged me off my account. Secondly, I can't login to my non-root account anymore. Whenever I enter the password, a black screen appears and I'm redirected to the login manager. Now I'm logged into the root account - which is a enormous security risk - but the Operating System left me no other choice. Can anyone help me fixing this problem?

FYI, I don't do any overclocking or uncommon modifications to the OS. BTW, I'm facing yet another problem - I can't install wine because there seem to be conflicting packages.

2017-12-23 22:53:38 -0600 asked a question How to securely delete files on Fedora 27 (ext4)?

I have some confidential files that I did encrypt, but there are still the original, unencrypted files on my HDD. What I want to do is overwriting these 25+ times with random data junk, making them absolutely and totally unrecoverable. The shred man-page says shred is not guaranteed to work on journal file systems, like ext. Is this statement correct? So I am looking for alternatives to shred for Fedora 27 (64-bit or architecture-independent).

2017-12-23 19:14:39 -0600 answered a question many problems to boot since last upgrade to 22

Try booting all various kernels installed on your hard disk. If none works, backup to an your /home partition to an external device, format the HDD and reinstall the OS. Furthermore, I would recommend upgrading to Fedora 26 or even better 27. This is due to discontinued support (updates) of all versions prior to 26. If you wish longer support periods for your OS version, purchase Red Hat Enterprise Linux (RHEL). They offer 5 1/2 years updates and assistance for their products. RHEL starts at only $49/year for Desktops.

2017-12-23 19:14:35 -0600 asked a question I created a 190-digit password... How secure is this?

I know that this sounds extremely paranoid and ridiculous, but today I formatted a USB flash drive with password-protected ext4 using a 190-digit password. It consists of upper-case letters, lower-case letters, words with random capitalization, numbers and special characters. I did this on my Fedora 27 machine. How long would it take all computers on Earth today combined to crack my password? Would a quantum computer be able to crack it? Is it even easier to crack the AES-256 encryption cipher?
