Hi, I wrote a small firewall with netfilter/iptables and it works pretty fine. Now I tried to run nmap on this firewalled computer and get this messages:
diebels:/etc/init.d# nmap -v -sS -O 192.168.0.2 Starting nmap V. 2.54BETA30 ( www.insecure.org/nmap/ ) sendto in send_tcp_raw: sendto(3, packet, 40, 0, 192.168.0.2, 16) => Operation not permitted Host bertisevil (192.168.0.2) appears to be up ... good. Initiating SYN Stealth Scan against bertisevil (192.168.0.2) sendto in send_tcp_raw: sendto(3, packet, 40, 0, 192.168.0.2, 16) => Operation not permitted sendto in send_tcp_raw: sendto(3, packet, 40, 0, 192.168.0.2, 16) => Operation not permitted How can I enable raw packets with iptables? Or can somebody provide me an example of iptables with nmap? thanks and bye, Sebastian
