I too have a cable modem, and over the past year or so there have been at least a dozen unwelcomed attempts to enter my machine. You can't rely on your ISP for any help with this. I would suggest that you disable all services you don't absolutely need, such as finger, daytime etc. I also suggest disabling ftp, telnet, and rlogin. If you need to login to your machine from a remote location, use the much more secure SSH. You can comment out the services you don't need in the files /etc/rc.config and /etc/inetd. You might also want to use a program such as nessus (www.nessus.org) to test for vulnerability. Alan Riggins Georges-Henry Portefait wrote:
