hi all
I have samba server running as a domain controller for my company.
now i want this server to be secure. how do i make DROP or DNEY to outside
world and allow for my internal users. i did as:
iptables -A INPUT -s 198.168.2.0 -p tcp --destination-port 139 -j ACCEPT
iptables -A INPUT -s 0.0.0.0 -p tcp --destination-port 139 -j DROP
iptables -A INPUT -s 198.168.2.0 -p udp --destination-port 139 -j ACCEPT
iptables -A INPUT -s 0.0.0.0 -p udp --destination-port 139 -j DROP
where 192.168.2.0 is my internal network.
I am not sure wheather this is working or not.how can test this?. is there
any better way to be more secure to this port netbios-ssn.?
Thanks
Paras.
