How can I get ngircd to listen on port 443? I don't need SSL, I just need a port that won't ever be blocked by ISPs/Wifi-hotspots/work networks

I tried adding 443 to the listening ports, but I get a Permission denied message.

Jun 6 11:18:08 ngircd[4605]: Can't bind socket to address 0.0.0.0:443 - Permission denied Jun 6 11:18:08 ngircd[4605]: Now listening on [0.0.0.0]:6666 (socket 8). Jun 6 11:18:08 ngircd[4605]: Now listening on [0.0.0.0]:6667 (socket 9). Jun 6 11:18:08 ngircd[4605]: Now listening on [0.0.0.0]:6668 (socket 10). Jun 6 11:18:08 ngircd[4605]: Now listening on [0.0.0.0]:6669 (socket 11).

Nothing else is using port 443 on my machine either. The command below returns nothing. sudo netstat -lntup | grep 443

Can this be done with ngircd?

Thanks
