Samba is used by sysadmin to overcome the problem of interoperability in a mixed environment where you have both Linux and Windows. It provides a common platform for both Windows and Linux to have a common sharing space.
Domain controller is a service which is used for centralized administration of users, groups or any objects in the network. This service enables us to manage, authenticate, and secure the users login and related data.
This tutorial explains various command line options available for the Linux shutdown and reboot commands.

Most of the usb dongle in market today comes with the drivers and application to use it in a managed way. The setup of this application is stored in its inbuilt memory. For windows system it autoruns and prompts to install the setup as soon as you plug your USB dongle. But, that is not the case for Linux system.

When you install PostgreSQL, by default connection to the database using TCP/IP is not allowed.
When you try to connect from a client to a remote PostgreSQL database using psql command, you might get “psql: could not connect to server: Connection refused” error message.
In the following example, from a client machine, we are trying to connect to a PostgreSQL database that is running on 192.168.102.1 server. As you see from the output, it clearly says that the remote PostgreSQL database is not accepting connection.
I’ll be conducting a hands-on workshop on Linux sysadmin. This will be an one day event with focus on hands-on training. In this all day workshop, you’ll be working on several lab exercises on a Linux system.
This workshop is for newbies or intermediate users of Linux who would like to become proficient in Linux system administration. Wide range of essential sysadmin topics will be covered including package management, user/group management, various security aspects of Linux, filesystem/storage, several networking utilities, monitoring, etc.
If you are a newbie in Linux system administration, or an experienced Linux power user, who does typical sysadmin tasks by yourself on your system, you’ll definitely find few books from this list helpful to add to your library.
Interrupts are signal that are sent across IRQ (Interrupt Request Line) by a hardware or software.
Interrupts allow devices like keyboard, serial cards and parallel ports to indicate that it needs CPU attention.
Once the CPU receives the Interrupt Request, CPU will temporarily stop execution of running program and invoke a special program called Interrupt Handler or ISR (Interrupt Service Routine).
