Hi!

I have linux RH8 with kernel 2.4.20-28.8, iptables v1.2.8. I have setup 
a firewall with some tcp ports opened (21,25,80,110,443) for servers.
Then I have ran a port scan  and scanned all 65535 tcp and udp ports. I 
was suprised that 3 ports were opened even if I didn't opened them in 
the configuration. These ports are tcp 389,1002 and 1720.
I have tried to block them manually by entering a drop command for these 
three ports but no success-they are still open.
What am I missing here? Is this some problem with iptables?
