Thanks to James, Clinton and Gretchen for the suggestions and comments. FWIW, while I do allow ssh on one machine this permission is limited to the internal network only. The printer in question is a network printer attached to an HP JetDirect print server. All the devices have 192.168.xxx.xxx IP addresses, except the iBook which is set to use DHCP. The firewall has all ports closed/stealth except for 25, 80 and 443. DHCP is allowed for internal IP's only. Still reading and looking...
