I'm not entirely sure how to pass argument to svcstatus.sh on the
command line. The web server runs as www-data. Here's what I tried.

www-data at pihole:~$ /usr/lib/xymon/cgi-bin/svcstatus.sh pihole.xx.lan http
Status: 403

Hello,

The Xymon index page is loading; however, when I attempt to drill down
into an individual service check (invoking svcstatus.sh), lighttpd
returns a 500 internal server error.

OS: Devuan Ascii 2.0
Kernel: Linux pihole 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u5
(2019-08-11) x86_64 GNU/Linux
Lighttpd: Version: 1.4.45-1
Xymon: Version: 4.3.28-2

Xymon and lighttpd were both installed from the official Devuan repos
using apt-get.

Here's my lighttpd config: https://clbin.com/F2LzF
Here's an strace: https://clbin.com/EuesM

Thanks,

Hi,

Can you try running svcstatus.sh by hand as the web user, with the
appropriate QUERY_STRING="HOST=pihole.xx.lan&SERVICE=http", and see what
happens? From the stack trace it seems to get as far as the bash fork,
but there's not much on the return to go on.
