Introduction Deploying set the hostname on freebsd 14 on a FreeBSD 14 machine differs from Linux in several important ways: packages come from the FreeBSD Ports Collection or the binary pkg repository, services are registered in /etc/rc.conf via sysrc(8), and firewall rules are written in pf.conf(5) syntax. This tutorial stays entirely within the standard base […]
Even with SSH key authentication enabled, a badly configured or temporarily accessible server with password auth still faces a constant barrage of brute-force login attempts. Fail2ban monitors log files for authentication failures, counts them per source IP, and when a configured threshold is crossed it issues a temporary ban by injecting a drop rule via […]
How to Set Up Data Deduplication on Windows Server 2025 Data Deduplication is a Windows Server role service that identifies and eliminates duplicate data blocks across a volume, storing only a single copy of each unique block and replacing duplicates with lightweight pointers. On typical file server workloads, deduplication routinely achieves 50–80% space savings, dramatically […]
