Ok. i just an nmap. these are ports i have open:
all tcp:
13 - daytime
25 - smtp
37 - time
113 - auth
587 - submission
6000 - x11
I only use this as a workstation. Which can i close. I don't need server services. i just browse the web. Can I close all of them? Are these open by default? I am running kde and firefox.
I still have to go through tcpdump. I think i will look at the rst packets. Does that seem right?
port 13 is ntp, right? Why do i need 37?
