Network bonding is a method used to combine multiple network interfaces into a single virtual interface, often to provide redundancy, improve network throughput, or load balance traffic across multiple interfaces. This technology is particularly useful in high-availability systems or environments that require higher network performance. In Linux, network bonding is implemented through the bonding kernel module, which allows multiple physical network interfaces to appear as a single logical interface. This guide explains how to enable and configure network bonding on a Linux system. The steps include loading the bonding module, creating a bonded interface, and configuring bonding options based on the network requirements. 1. Prerequisites Before configuring network bonding, you need to ensure that: The Linux system has multiple network …

Network configuration in Ubuntu 18.04 LTS using netplan
With Ubuntu 18.04 onwards, configuring IP addresses stands different from the older versions. When comparing with the previous versions the Ubuntu is using a new utility called Netplan – another order line arrange design utility, to arrange an IP address. Netplan has been presented by Ubuntu engineers in Ubuntu 17.10 where we no longer use the “interfaces” file to configure IP address but does the task using a YAML file with all default arrangement documents found under /etc/netplan/ directory. In this blog, we will check on how to design static and dynamic IP address in Ubuntu 18.04 LTS server. (more…)
The constantly increasing need for computing power is driven by the creation, development, and deployment of various processor intensive tasks. In most cases, individuals, businesses, and even academia find it hard to harness increased computing power without making a significant investment in the infrastructure, which could include supercomputers. SONM, a blockchain powered distributed computing platform has a solution that might solve the issue for many. SONM is a universal fog supercomputer. It allows users in the network to share unused processing power from their devices. This helps others who need additional computing resources. The peer-to-peer network supports many applications. These include video processing, CGI rendering, DNA analysis, complex scientific calculations, and website hosting.Like any other blockchain system, SONM also rewards …
The Network File System (NFS) was originally developed by SUN Micro-systems that allows communications between Linux/Unix systems. It allows you to mount your local file systems over a network and remote hosts or clients to interact with them as they are mounted locally on the same system. Benefits >> Central Data Management. >> Allows local access to remote files transparently. >> Very good for local or reliable connections Important NFS configuration file /etc/exports : All files and directories which need to be exported are defined in this which is located in server. Setup Need to have two CentOS systems : NFS Server NFS Client Server yum install nfs-utils nfs-utils-lib chkconfig –levels 235 nfs on service nfs start Here we are …

Nowadays, brute force attacks on servers/websites are frequent. A brute force attack is generally a password-guessing technique. It is a type of attack that tries every possible combination of characters or data in order to find the decrypted message. Brute force guarantees finding the key – it tries every possible combination and does not rely on any potentially incomplete dictionaries or lists of possible keys. cPHulk Brute Force Protection is an inbuilt protection used in WHM to prevent brute force attacks. cPHulk Brute Force Protection will detect and block continuous failed login attempts from IP addresses. cPHulk is a brute force protection system developed by the cPanel team and is exclusive to cPanel / WHM control panels. It has been integrated …
