After scanning a couple internet servers and seeing they use only 2 or 3 open ports, i scanned my machine and here is the output:
Port State Service
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
37/tcp open time
79/tcp open finger
111/tcp open sunrpc
113/tcp open auth
515/tcp open printer
587/tcp open submission
6000/tcp open X11
This looks like way too many open ports for me. How do i close them all off except the needed ones.
I use eth0 for internet connection. I use pop3/smtp mail client. no ftp or web server, no shared printer. anything else you need to know before you can help close ports, just let me know.
