I have no firewall installed on a linux box and after running nmap have found that there are three open ports
[root@PCLOS2007 ~]# nmap 127.0.0.1
Starting Nmap 4.20 ( http://insecure.org ) at 2008-02-08 14:25 GMT
Interesting ports on PCLOS2007 (127.0.0.1):
Not shown: 1694 closed ports
PORT STATE SERVICE
22/tcp open ssh
139/tcp open netbios-ssn
445/tcp open microsoft-ds
AS I am not running iptables etc, just for curiosity's sake,
what would be the best way to open and close ports via command line ?
One could edit the inetd.conf
file but this is becoming redundant in a lot of Linux flavours.
I would like to open port 79 so that I can finger from another machine.Is there a manual way of opening / close this port or is the port opened by the finger daemon at start-up ?
