Shell unprivileged service run check

[mro]

how would an unprivileged user detect if certain services like cron, ntp etc. are running?

Like at https://rec.mro.name/app/monitor.cgi
(source at https://codeberg.org/mro/internet-radio-recorder/src/branch/master/pages/app/monitor.cgi)

A rule file in /usr/local/etc/sudo/?

 

[covacat]

either sudo or run a daemon listening on a local socket (netcat/inetd based shell script)
make the socket available to www process / just use your imagination

mro are you wanting to run something like 'ps -aux' from a cgi script?

no, but e.g. $ service cron status and check if that returns 0 and display the text.

P.S.: I clarified the initial question who runs what.
