I have rh9, kernel
2.4.20-8, I want all ports to be closed but 25 & 110 are still open. I'm
sure that no service are listening on them, the local nmap reports nothing but
scanning it with a crossover cable, the Win Nmap reports them
opened.
I tried with iptables droping everything, with the
same result.
I have also tried telneting these ports,
getting a connection for 20 seconds.
Any ideas ???
NMapWin v1.3.1
Starting nmap V. 3.00 ( www.insecure.org/nmap
)
