User of #FreeBSD, you鈥檇 like to test 14-CURRENT ahead of the release with #OpenSSL 3 in base? Give the Pull-Request at a shot and let us know if anything fails or isn鈥檛 as expected!

Okay...un truquillo que por desgracia (RTFM!!), poca gente conoce... 驴Has querido levantar una aplicaci贸n al iniciar tu m谩quina y no se te ocurre c贸mo porque no es un servicio??? F谩cil...en tu crontab usa el "@reboot"

Ac谩 dos ejemplos:

***Levanto un vncserver:
@reboot /usr/local/bin/vncserver -x509key $HOME/.vnc/ares_x509_ca.key -x509cert $HOME/.vnc/ares_x509_ca.pem -SecurityTypes X509Vnc :1

***Levanto syncthing
@reboot /usr/local/bin/syncthing



Hardening the #FreeBSD shared memory (SHM) subsystem in #HardenedBSD, part one: prevent abuse of shm_open(2)/memfd_create(2) for capsicum-enabled processes.

A post-exploitation technique becoming more commonplace is to abuse memfd_create(2) to create memory-backed file descriptors. These file descriptors can be used with fdlopen(3) to load and execute a shared object file using anonymous memory mappings, making forensics more difficult.



Proof-of-Concept test case, abuse of memfd_create(2) to fdlopen(3) a shared object:

Welp, #FreeBSD ports flavors are under documented. I want to install git-lite from the ports tree, but devel/git-lite was merged to devel/git. I can't just make install there as it'll install the full version, and searching the handbook only turns up how to make a port flavor, but not install a flavor.

my first update/upgrade and full #XFCE config - everythig works fine! I need to install #i3...
screenshot of GhostBSD desktop with XFCE...

So to try things out in a more #FreeBSD way, I'll be trying my hand at #jails in a way to sandbox processes similarly to chroot

Wonder if I can ultimately sandbox something real complex like Firefox and other internet-facing applications

MidnightBSD 3.0.0 Released. This is What's New

#bsd #opensource #freebsd #midnightbsd

#FreeBSD 14-CURRENT quite happily works on #Pine64 SOpine aka A64-LTS on Baseboard.

The only thing that doesn't work is the VGA console as the HDMI output is not detected (likely some FDT fixes needed), but I don't care because it will end up in a Clusterboard.

The moment of truth will be when I insert it into the Clusterboard though as the 13.2 image suffered from the old issue with Ethernet not working...
Pine64 SOpine installed in Baseboard

#FreeBSD 13.0 and up ships with a built-in lua interpreter, in the base system, and a jail interface for it.

On my 7 year old laptop, I can create & tear down 1_000_000 #jails in ... 12 seconds. On my similar aged desktop, under 4 seconds.


jail = require("jail")
all = jail.allparams()

for i=1,1000000
local name = "demo_" .. string.format("%04d", i)
jid, err = jail.setparams(name, {persist = "true"}, jail.CREATE)
if not jid then

-- skip slow i/o
-- print(name .. ": " .. jid)

jid, err = jail.setparams(name, {persist = "false"}, jail.UPDATE)
if not jid then

** no filesystems nor packet filters were harmed in this experiment
