As of 2014-11-26, orca doesn’t start any more and reports the same error. When started via GNOME’s Universal Access, the process starts but errors out after 10 seconds or so.

FWIW, I’ve verified that the speech server works with test-speech from the libgnome-speech-dev package.

I see packets to lo, tcp port 4101, being blocked (both in IPv4 and IPv6). According to http://www.networksorcery.com/enp/protocol/ip/ports04000.htm, ports 4101-4104 are “Braille protocol”. I suspect this might be the culprit.

This seems correct. After a sudo do_not_ever_run_me, orca works just fine.

Manually added

                daddr 127.0.0.1 proto tcp syn dport 4101 {
                    mod owner uid-owner amnesia ACCEPT;
                }

to the IPv4 OUTPUT section, and

daddr ::1 proto tcp syn dport 4101 {

mod owner uid-owner amnesia ACCEPT;

}

proto icmpv6 {

ACCEPT;

}

</pre


to the IPv6 OUTPUT section, no more firewall logs, but Orca still crashes. I bet stuff is still being blocked, but without logs due to our INPUT chains defaulting to simply dropping. To be continued.
