About
secure-server-setup-skills is a Claude Code marketplace distributing five Agent Skills for Linux VPS hardening against brute-force scans and misconfiguration. Install the catalog with npx skills add mikr13/secure-server-setup-skills, then prompt your assistant to run ssh-hardening, firewall-configuration, fail2ban-setup, auto-updates, or backup-strategy workflows with bash scripts for Ubuntu, Debian, CentOS, and RHEL. Reach for it immediately after provisioning a public-facing server when password SSH, open ports, or missing patches are still defaults. Each skill documents test-first sshd changes, UFW default-deny policies, jail.local templates, and backup locations so you do not lock yourself out while securing the box.
- Bundles 5 skills: ssh-hardening, firewall-configuration, fail2ban-setup, auto-updates, backup-strategy
- Install via npx skills add mikr13/secure-server-setup-skills or bunx skills add
- ssh-hardening edits sshd_config with sshd -t validation before restart
- UFW default-deny firewall-configuration skill with service-specific allow rules
- fail2ban-setup creates jail.local and protects SSH from brute-force IPs
