Where is the PXE configuration file?

The PXE server reads and executes configuration files located in pxelinux.cfg director y from TFTP root path in this order: GUID files, MAC files and default file. The directory pxelinux.cfg has been already created and populated with the required PXE default configuration file because we’ve earlier extracted the required netboot files from Debian netinstall archive to /srv/tftp sirectory. There’s no need to further modify the PXE default configuration file from pxelinux.cfg directory. However, the file that actually controls the initial boot menu for Debian is named txt.cfg and is located in /srv/tftp/debian-installer/amd64/boot-screens/ directory. The default pxe configuration file from pxelinux.cfg directory is actually a soft link that points to txt.cfg file. In order to change or add other options to be passed to kernel during the net boot process or add other entries or boot-up other Linux distributions via PXE server, you should open the default txt.cfg PXE configuration file with the below command and make the appropriate changes.

What is MariaDB bind address?

Some MariaDB packages bind MariaDB to 127.0.0.1 (the loopback IP address) by default as a security measure using the bind-address configuration directive. Old MySQL packages sometimes disabled TCP/IP networking altogether using the skip-networking directive. Before going in to how to configure these, let's explain what each of them actually does:

Why is MariaDB bound to loopback?

MariaDB is bound to the loopback interface by default because it makes it impossible to connect to the TCP port on the server from a remote host (the bind-address must refer to a local IP address, or you will receive a fatal error and MariaDB will not start). This of course is not desirable if you want to use the TCP port from a remote host, ...
