i got a slack installation running behind a router. I've disabled iptables since the router does the firewall work. However, only root can be the target of incoming connections. a quick example:
Azureus running as root can download and upload torrents without any fuss.
Azureus running as any other user can download, but cannot upload since the incoming port cannot be opened.
What gives? did i forget to add the user to a specific group?
