With help of AI I have written a simple bash scrippt that
output average network bandwidth by reading directly
from /proc/net/dev
I think 70 lines is better than some special app with
writing output parser for it. #dailyreport #linux #administration #permissions #secops #sudo #doas #network #bash #proc
Title: P0: Doas instead of sudo [2025-05-04 Sun]
#sudo #doas #network #bash #proc
Sudo command is overburden, I switched to Doas tool from
FreeBSD project that lighter by weight. I don't use SU
command, because it require PAM framework, that I don't
use.
Before:
larry ALL=(ff) NOPASSWD: ALL
sudo --preserve-env=WAYLAND_DISPLAY,XDG_RUNTIME_DIR -u ff
firefox
After: #sudo #doas #network #bash #proc #dailyreport #linux #administration #permissions #secops #sudo #doas #network #bash #proc
Zabte mě! Oddám se třeba samotnému Luciferovi, jen když to za mě vyplní!

No entendía por qué mi máquina virtual con #devuan andaba tan lenta, y claro, el problema fue capa 8: yo mismo le configuré 512MiB de RAM 😅
Sí, estoy haciendo pruebas de estrés en el sistema, análisis de memoria libre, disponible, load average, y PSI.
El video que estaba preparando sobre estos temas se está extendiendo mucho... creo que van a salir 2 videos, para poder sumergirnos más en algunos detalles 😃
