Linux Lite on older CPUs with PAE

On machines with older Pentium M ™ and Celeron M ™ processors, there is an extra requirement to get Linux installed, I’ve encountered this mainly with Linux Lite as that is the OS of choice I use for older systems.

Important: This only works if your installation is failing with this error kernel requires features not present on the CPU: PAE

Net Interface not loaded in Debian

I had to build out a Debian server for a project I was working on at home and my internet went down just as I started the build, deciding not to wait until it came back up; I went ahead with the build and finish the configs, upgrades and whatever else would be needed once the interwebs started working again.

The major issue I had was that networking was not able to be configured due to no connection found, that in turn left my software config to use the install media alone. Continue reading Net Interface not loaded in Debian

Linux Malware Mines for Cryptocurrency Using Raspberry Pi Devices

A Linux trojan detected under the generic name of Linux.MulDrop.14 is infecting Raspberry Pi devices with the purpose of mining cryptocurrency.

According to Russian antivirus maker Dr.Web, the malware was first spotted online in the second half of May in the form of a script that contains a compressed and encrypted application.

Experts say the initial infection takes place when Raspberry Pi operators leave their devices’ SSH ports open to external connections.

Once a Raspberry Pi device is infected, the malware changes the password for the “pi” account to:

grub-pc (2.02~beta2-36ubuntu3.10)

I’m running an Ubuntu server and the other day while running updates I started getting the following error:

Setting up grub-pc (2.02~beta2-36ubuntu3.10) ...
/var/lib/dpkg/info/grub-pc.postinst: line 703: syntax error near unexpected token `fi'
dpkg: error processing package grub-pc (--configure):
 subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
 grub-pc
E: Sub-process /usr/bin/dpkg returned an error code (1)

Opening /var/lib/dpkg/info/grub-pc.postinst I found:

        if dpkg --compare-versions "$2" lt-nl 2.02~beta2-36ubuntu3.10 then
          if [ -e "/boot/efi/EFI/${bootloader_id}/fbx64.efi" ]; then
            rm -f "/boot/efi/EFI/${bootloader_id}/fbx64.efi";
          fi
        fi

There was a missing semicolon in the first line and that’s what was breaking my update. I updated it and the error went away:

        if dpkg --compare-versions "$2" lt-nl 2.02~beta2-36ubuntu3.10; then
          if [ -e "/boot/efi/EFI/${bootloader_id}/fbx64.efi" ]; then
            rm -f "/boot/efi/EFI/${bootloader_id}/fbx64.efi";
          fi
        fi

Installing Linux Kernel v4.10

I started using CentOS over several other Distros that I have been testing ever the years. I still have an Ubuntu laptop just to keep up to date with things seeing that it’s one of the most popular ones.

I’ve covered installing Kernels before but I wanted to refresh that topic and include how to do it on CentOS.
