    New blog post: GeoIP-Aware Firewalling with PF on FreeBSDRunning a mail server means constant brute-force attempts. My solution: geographic filtering. SMTP stays open for global mail delivery, but client ports (IMAP, Submission, webmail) are restricted to Central European IP ranges only.Result: ~90% reduction in attack logs, cleaner signal-to-noise ratio, smaller attack surface.Using MaxMind GeoLite2 + PF tables with ~273k CIDR blocks.https://blog.hofstede.it/geoip-aware-firewalling-with-pf-on-freebsd/#FreeBSD #InfoSec #SysAdmin #pf #DevOps

    How far along has tarfs gotten in #FreeBSD? I've been watching @dch 's talk on immutable FreeBSD from EuroBSDCon 2023 (1 hour wasn't enough to cover your talk!)I've been looking into applying the principles but sadly it won't be for $day_job as they've no interest in my FreeBSD ideas but for something else.I'm curious which sockets were used in the jails. Was /tmp replaced with tmpfs in the jail and did you use a socket to talk to syslog-ng on the host? https://youtu.be/5oHLU9w1vVk

    RE: https://mastodon.bsd.cafe/@stefano/115547315643919873For more than a day, I was reluctant to boost Stefano's article. After spending some time in Lobsters, I'm ready. <https://lobste.rs/s/l4vg9a/this_isn_t_battle>, in particular <https://lobste.rs/s/l4vg9a/this_isn_t_battle#c_lp9mgb>… thanks.#FreeBSD
