Hello,
how could it be achieved to run
e.g.
shutdown -h now
from a CGI script on a system where SELinux is set to ENFORCING?
Short answer: don't. You could probably create a custom selinux policy that allowed it but you'd be opening your system up to more security issues.
If it were me, I'd have the cgi drop a file in a known location, and have an external process (possibly started through cron) monitor the file, then run shutdown conditionally.
I thought of such a mechanism; I also want to show some states which
also need priviledged rights
e.g. arp, iptables -L -n -v, ...
but these are many write access to the disk, shutdown/restart just
generate one write access by the CGI script
and the cron job deletes this generated file and does the shutdown or
restart
where is the "best" directory I could do this "communication"?
e.g. /var/lib/box?
Thanks,
Walter
