UDP scan taking more time against Linux machine

Hello, I was conducting UDP port scan for (0-65535) port range, against a linux machine(Ubuntu 11.04) but it took more than 18 hours to finish the scan. After searching on Internet I found the reason that the linux kernel limits the ICMP error message rate i.e. Linux 2.2 to Linux 2.4.9 limits the destination unreachable message generation to 80 per 4 secs, but the linux kernel I am using is of higher version. It would be really helpful if somebody can explain me the reason behind this behavior. Thanks in advance. _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
