[SSHGuard-users] sshguard.conf dictates sshg-fw-iptables backend: still runs sshg-fw-firewalld?

[Kevin B. <kev...@gm...>]

We're running: sshguard-2.4.2-bp157.1.6.x86_64

In

 /etc/sshguard.conf

we have

BACKEND="/usr/lib/sshg-fw-iptables"

but, as the service (systemd invoked on a SLES 15 OS) starts,
we see the following, in var/log/messages

2026-09-01T14:53:34.634459+08:00 <hostname> sshguard[93330]: blacklist: blocking 0 addresses

2026-09-01T14:53:34.640565+08:00 <hostname> sshguard[93332]: sshg-fw-firewalld: Could not initialize firewall

so why is SSHGuard even bothering to look for firewalld-related
things, which we aren't running, hence the config file setting?

>From what I can see, the "firewall-cmd: command not found" messages
stop after "line 16", however, given

# wc -l /usr/lib/sshg-fw-firewalld
65 /usr/lib/sshg-fw-firewalld

who knows which file the "line 16" is in?
