Configuring sudo privileges for specific users on Linux systems involves editing the sudoers file or creating a custom configuration file within the /etc/sudoers.d directory. Here’s a step-by-step guide: Step 1: Edit the sudoers File Open a terminal and log in as a user with administrative privileges. Use the visudo command to safely edit the sudoers […]
Securing data on shared storage systems is critical to prevent unauthorized access, data loss, or corruption. Here are key best practices and strategies to ensure robust security: 1. Implement Access Control Policies Role-Based Access Control (RBAC): Assign permissions based on roles to ensure users only access the data they need. Least Privilege Principle: Limit access […]
Optimizing ZFS (Zettabyte File System) for high-throughput workloads requires careful planning and tuning at multiple levels—hardware, ZFS configuration, and workload-specific adjustments. Below are the best practices and considerations: 1. Hardware Considerations a. Storage Devices Use SSDs for ZIL and L2ARC: Use high-performance SSDs or NVMe drives for the ZFS Intent Log (ZIL) to improve synchronous […]
Configuring and securing SMB (Server Message Block) file shares on Windows Server is a crucial task to ensure data accessibility and protection. Below are the steps to configure and secure SMB file shares effectively: 1. Configure SMB File Shares Step 1: Create the File Share Log in to the Windows Server: Use an account with […]
Troubleshooting slow SCP (Secure Copy Protocol) or SFTP (Secure File Transfer Protocol) file transfers on Linux servers involves identifying bottlenecks and optimizing the system. Here is a systematic approach to diagnose and resolve the issue: 1. Check Network Performance Bandwidth: Verify the available bandwidth between the source and destination servers using tools like iperf or […]
Configuring network bonding (also known as NIC teaming or link aggregation) for servers enhances network performance, redundancy, and fault tolerance. Here’s a step-by-step guide to configure network bonding: Prerequisites Network Interface Cards (NICs): Ensure your server has at least two physical NICs available for bonding. Switch Configuration: Configure the switch to support bonding/teaming (e.g., LACP […]
