# (U)RXVT VULNERABILITY
#
# In rxvt-based terminals, ANSI escape sequence ESC G Q (\eGQ, \033GQ, \x1bGQ)
# queries the availability of graphics and the response is received from stdin.
# However, rxvt responds to the query with a newline-terminated message, which
# is retarded and exposes goatse-wide gaping security holes in many popular CLI
# programs when executed inside an rxvt terminal window.
#
# [def@arch ~]$ printf '\eGQ'
# ^[G0
# [def@arch ~]$ 0
# bash: 0: command not found
#
# The latter command (i.e., 0) executes automatically without user interaction.

# FIX -------------------------------------------------------------------------
#
# Don't use rxvt or any of its derivatives. Stay the fuck away from xterm also.
tf
# st(1) is a viable solution if you ever plan to `cat /var/log/access.log` or
# otherwise handle untrusted data from questionable sources.

systemctl status servicename
и да, параметры на лету тоже можно. Для отдельных сервисов или на всю систему логи редиректить (syslog, plaintext log. remote log) можно. Крутить крутилки cgroups и namespaces, на пару с capablities, само собой. Регулировать работу omkiller? Разумеется! Ну и так далее и тому подобное. И да... покажи мне такие же метрики в своём руните.
