Hi, I am using nmap 5.00-2 in Ubuntu and 4.75 in opensuse. Both versions doesn't respect the order of ports using the -p flag, even using the -r (don't randomize) flag. nmap -r -p T:7894,8945,1234,5678 -PN localhost Starting Nmap 5.00 ( http://nmap.org ) at 2009-11-18 12:04 BRST Warning: Hostname localhost resolves to 2 IPs. Using 127.0.0.1. Interesting ports on localhost (127.0.0.1): PORT STATE SERVICE 1234/tcp closed hotline 5678/tcp closed unknown 7894/tcp closed unknown 8945/tcp closed unknown Nmap done: 1 IP address (1 host up) scanned in 0.15 seconds The order specified was 7894,8945,1234,5678 but the scanning order was 1234,5678,7894,8945. This could be a problem when using nmap to trigger firewall actions that are based on the strict order of hits, i.e. port knocking. --------------------- Miguel A.
