LVS (Linux Virtual Server) operates on a three-tier architecture: the load balancer, server pool, and shared storage. The load balancer directs client requests to servers in the pool, presenting a single virtual IP (VIP) address. Servers in the pool handle actual requests, while shared storage ensur...
Network interface bonding in Linux aggregates multiple physical network interfaces into a single logical interface too enhance bandwidth, load balancing, and redundancy. This technique is essential in complex network environments for improving performance and availability. Linux supports several bon...

Spring Boot and Spring Cloud applications support both fixed and random port assignment. However, both methods present mangaement challenges. Fixed ports risk conflicts, especial in microservice architectures. Random ports, while avoiding conflicts, introduce unpredictability in service discovery an...
Implementing a client for the FTP control and data channels requires speaking a simple, line-oriented, text protocol over TCP. Commands are ASCII lines terminated by CRLF (\r\n). Replies are lines beginning with a three-digit code followed by text and CRLF. Only the numeric code is needed for flow c...

SO_REUSEADDR and SO_REUSEPORT actually do on TCP sockets and demonstrates how to use them for common tasks such as graceful restarts and running multiple listeners on the same port. What SO_REUSEADDR enables On most Unix-like systems, SO_REUSEADDR affects TCP sockets in several ways: Lets a server b...
Access Control Lists (ACLs) are an essential networking technology employed to manage and filter traffic based on specified criteria, thereby enhancing security and enforcing access control policies. ACLs Overview ACLs enable network devices to make decisions on whether to permit or deny data packet...
