Crontab in linux- Examples and Command

A cron job in Linux is a time-based job scheduler. It is a utility that allows you to schedule and automate the execution of scripts, commands, or programs at specific intervals or at predetermined times. Cron jobs are commonly used in Linux and other Unix-like operating systems to automate repetitive tasks, such as system maintenance, log rotation, backups, and periodic data processing. The cron service is responsible for running these scheduled tasks. It reads a configuration file called the "crontab" (short for cron table) to determine when and which commands to execute. Each user on a Linux system can have their own crontab file, which lists the cron jobs specific to that user The crontab file uses a specific format to define the schedule of a cron job. It consists of six fields that specify the timing of the job: scss * * * * * command_to_be_executed | | | | | | | | | +----- Day of the Week ( 0 - 7 ) (Sunday = 0 or 7 ) | | | +------- Month ( 1 - 12 ) | | +--

How TO Manage Groups Ad User on linux

Linux Admin - User Managemen When discussing user management, we have three important terms to understand − Users Groups Permissions We have already discussed in-depth permissions as applied to files and folders. In this chapter, let's discuss about users and groups. CentOS Users In CentOS, there are two types accounts – System accounts − Used for a daemon or other piece of software . Interactive accounts − Usually assigned to a user for accessing system resources . The main difference between the two user types is − System accounts are used by daemons to access files and directories. These will usually be disallowed from interactive login via shell or physical console login .. Interactive accounts are used by end-users to access computing resources from either a shell or physical console login. With this basic understanding of users, let's now create a new user for Bob Jones in the Accounting Department. A new user is added with the adduser command. Following

User quota in Linux step by step

Linux Admin – Quota Management As a Linux administrator, quota management is an important aspect of managing file systems and controlling disk usage by users. Quotas allow you to set limits on the amount of disk space a user or a group can consume. Here's a general guide on how to manage quotas in Linux: Enabling Quota Management in C Linux is basically a 4 step process – Step 1 − Enable quota management for groups and users in /etc/fstab. Step 2 − Remount the filesystem. Step 3 − Create Quota database and generate disk usage table. Step 4 − Assign quota policies. Enable Quota Management in /etc/fstab First, we want to backup our /etc/fstab filen − [root@localhost ~]# cp -r /etc/fstab ./ We now have a copy of our known working /etc/fstab in the current working directory. We made the following changes in the options section of /etc/fstab for the volume or Label to where quotas are to be applied for users and groups. usrquota grpquota As you can see, we

Why use vSAN in VMware?

VMware vSAN, which stands for VMware Virtual SAN, is a software-defined storage solution offered by VMware. It is a component of VMware's vSphere virtualization platform and is designed to provide highly scalable, high-performance shared storage for virtual machines (VMs) in a vSphere environment. vSAN allows you to pool together the direct-attached storage devices (such as hard drives or solid-state drives) from multiple servers in a vSphere cluster and create a distributed storage infrastructure. By aggregating the storage resources from these servers, vSAN creates a shared storage pool that can be utilized by VMs running on those servers. Key features and benefits of VMware vSAN include: Hyperconverged Infrastructure (HCI): vSAN is a key component of VMware's HCI solution. It combines compute, storage, and virtualization resources into a single software-defined platform, simplifying data center operations and reducing hardware costs. Highly scalable and elastic : vSAN a

What is? Dhcp Server In-Networking

A DHCP (Dynamic Host Configuration Protocol) server is a network service that automatically assigns IP addresses and other related network configuration parameters to devices on a network. It simplifies the process of network configuration by dynamically allocating IP addresses to devices as they connect to the network. PLAN the IP Address Range and Exclusions Besides degerming how to places the DHCP server into the network structure, you also to plan the ip address ranges you" ii use as well as which ip addresses to reserve or exclude from this pool of addresses. use the following list to help plan the IP address ranges to use and exclude . . Determine the range of ip addresses that the DHCP server will manage. Most likely, this will be private address range such as 10.x.x.x or 192.168.x.x, or a site-local addresses such as FEC::/10. .Make a list of any IP addresses to exclude to support hosts with static IP addresses. only DHCP server and hosts that don't' works as
