I used iptables to create a firewall for my Linux system for a while, but my script and firewall rules were a mess. Then I wanted to move to nftables, which is intended to replace iptables, hoping to get something better. I had also wondered about how to forward traffic between different...

I installed a ton of packages so I could play audio files from the system console. It still doesn't play them. It says it can't find a valid sound driver, even over 2 GB later. Now something is mounting /tmp as rw when /etc/fstab says it should be ro. Whatever it is is keeping /tmp "busy" so...

I need some step by step advice to get grub set up the correct way. 1) I need to install grub on /dev/sda so it only boots Windows, /dev/sda2, regardless of whatever other devices may or may not be connected. I cannot use fdisk.exe /mbr because I don't have it and can't get it. Windows is...

If I see /usr/bin/whiptail just one more time I may have to smash that laptop with a brick and throw the shattered remains off of the tallest cliff I can find! I told apt to answer yes to every question. There are over fifty seven thousand packages that demand to be installed in order to...

I am using the current version of Debian Linux. I installed with the netinst CD. I still can't get the network working so I can't finish the installation process. It looks like /etc/inittab is being phased out of Linux and is being replaced with systemd. What is the correct way to set all of...

When I boot up, Linux gives me 53 lines and 180 columns on the screen in text mode. How can I change this so it gives me 25 lines instead? I should have around 90 columns or so after doing so. The letters are really small. I need them to be bigger and easier to see.

I have a laptop PC with a SCSI drive controller. I need to buy and use an external SSD connected with USB. I cannot find any external SSDs that say they are SCSI devices. Since the external drive will be connected with USB will this matter? I am currently fighting with a Western Digital hard...

I downloaded a C compiler for my tablet from the Play Store called C4droid. It cost $3. It locally compiles and runs a C program. The set up of an Android system is a problem though. I feel like I'm living in a tiny little box and every time I try to move to do anything I bump in to a wall...

What exactly is an APK file? Is it an acronym? Can I write C source code, perhaps including inline assembly, and then have cc or gcc produce an APK output file so I can transfer it to my Android tablet and run the newly written app on my tablet? I have both an ftp server and client on my...

I hope this is the correct place to put this. I couldn't find a topic dedicated to Android tablets. I am using an ASUS ZenPad S 8.0 running Android Lollipop 5.0 with a device designation P01M. I have just downloaded the KingRoot 5.2.2 APK file. I have scanned it and Avast says it's free of...

I used to use Slackware Linux kernel 1.2.13 with gcc 2.7.0 years ago. I know things have changed over the years. I'm am using an Android tablet running Lollipop 5.0. I found entries for 25 different kinds of Linux on this website. What makes each of them different? What are their pros and cons...
