Attending ARIN on the Road in Winnipeg: IPv6-focused presentations, hands-on with RESTful web services API, discussions on DNSSEC/RPKI implementation, and networking with ARIN leadership.
Personal milestone: all public-facing services now dual-stack IPv6—anycast web, mail (SMTP/IMAP/POP3), DNS (authoritative/recursive), SSH/FTP, SSL VPN, SaltStack, Nagios, plus native home connectivity via HE tunnel.
Using SaltStack jinja templating to deploy custom fail2ban jail.local configs: mail server-specific protection for dovecot/postfix auth failures with iRedMail hardening policies.
Using curl to reveal the final destination of shortened URLs before clicking: one-liner command with redirect following and a simple shell script wrapper for safe link verification.
