The mailing list for listmasters using Sympa

["Stefan Hornburg (Racke)" <address@concealed>]

Hello Otto, 

please post an excerpt of the Apache log. 

A common error is the wwsympa_url configuration parameter not matching the incoming host name.

Regards 
Racke

Confession: I'm doing bad, unauthorized and experimental things.
The reason for this is extreme laziness, not wanting to maintain
manually tarball-installed packages.

I have a Red Hat Enterprise Linux release 8.4 (Ootpa) server,
where I have installed by hand the following packages, and the
dependencies that follow with them, all satisfied:

sympa-6.2.62-1.el7.x86_64
sympa-httpd-6.2.62-1.el7.x86_64
foundation-icons-fonts-3.0-2.el7.noarch.rpm
js-respond-1.4.2-1.el7.noarch.rpm

These standard RHEL8 repository packages were also installed:

mariadb mariadb-server mariadb-server-utils mod_ssl

The end result is a Sympa server that is running, the httpd server
is accepting connections, but for some reason wwsympa (via spawn-fcgi)
doesn't really seem to be all there. Guessing from strace, it seems
to be getting queries from httpd and responding to them, but those
responses somehow never seem to come back to httpd:

Maybe I'm deluded, and these unnatural experiments have twisted my little
mind, but I really think I'm fairly close getting this thing working.

Apart from the fact that I have no idea why the web server and fcgi aren't
talking with each other. Anyone have suggestions for debugging this?
I must be missing something fairly obvious.

Apache httpd is indicating in logs that connections are being responded to,
wwsympa doesn't seem to be logging anything anywhere.
Before you ask, selinux is disabled.
