I just updated to the latest ROM last night. I put in my Linksys 802.11b wireless card and did a port scan. I can see ports 111, 4242, 4243, & 4992, but I can't seem to connect to any of them. I'm behind a firewall at work and at home, so I'm not extremely worried, but I would like it to be as secure as possible.

According to http://www.linuxjournal.com/article.php?sid=5902 At least, the latest version of the ROM makes the FTP server open only on the USB network interface Document is dated Jul 2, 2002. My ROM is 2.12 (machine was bought on July 9!) and if I try to connect to port 4242 over wireless network the connection is terminated immediately. I haven't tried to connect via USB yet (not even unwrapped the USB adapter). -- rgds Stephen
