Hi Jake, Connecting to a hub without a firewall means that each machine becomes an exposed node and that all communications between them can be picked up by a packet sniffer.
So that's the root passwords given away and a shortcut to either having the ISP pull the account or being RBL-ed. Stop looking for a reason not to set up a firewall. It will save you work and money. The HOWTO is also easy. -- Patrick "sig-free and proud of it" Kirk GSM: +44 7876 560 646 ICQ: 42219699
