Episode 14 of Linux Server Admin with Fexingo: Sysadmin, Bash, and Server Engineering. Lucas and Luna explain why routing all SSH traffic through a dedicated bastion host dramatically reduces your attack surface and simplifies compliance. They walk through a real-world setup using a $5/month VPS as a jump box, discuss sshd hardening (disabling root login, key-only auth, port knocking), and cover audit logging with auditd. The episode also details how to forward SSH agent keys securely via ssh -A, and what happens during a typical breach attempt when no bastion exists. Perfect for sysadmins managing fleets of 10 to 1,000 servers who want one clear, practical improvement this week.
