Question Ports that are already opened?


I used nmap, have ports 21,22, and 23 open. I was just wondering how they automatically set themselves up w/o me having to configure it using my router....Thanks.

Well, do you have FTP, SSH and Telnet running on your machine or router? What kind of router?

21 = FTP
22 = SSH
23 = Telnet

21 ftp
22 ssh
23 telnet


SSh is on by default when you install, what services does your router offer?


Unless you explicitly set them up I doubt you're runing ftp and telnet on your comp.

Thats what I figured, however, the ftp daemon vsftpd is running fine along with ssh and telnet. The ports are open according to nmap and I can ssh and telnet to my comp...still having problems with ftp...however, I was wondering exactly what process occurs in configuring this if I didn't manually do it...is the daemon communicating with the router to open the ports?....I was mainly wondering the details of it rather than which port corresponds to which service...sorry if my question was a little confusing. Thanks.
