As UDP is a connectionless protocol, it can take a very long time to complete. There are also other factors involved such as how our ISP handles ICMP traffic, firewallls and just plain old slow computrs scanning even slower ones. I have hd to wait long time to scan some of my friends networks, and it has taken many, many hours. Best of luck to you. most sincerely, Richard -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of whitehat Sent: Monday, January 28, 2008 12:23 PM To: pen-test Subject: Problem with NMap Scans Hi List, I'm using NMap for port scanning and I never faced any problems. But in recent times when I scanned some systems it was showing nearly 8.00 hrs for SYN Scan and 19.00 hrs for UDP Scan to complete. I tried with '-T4' option which is aggressive in nature but it is of no use. Can anybody help what is going on there????? Because we cannot wait up to 8.00 or 19.00 hrs if the Green Zone timings are on. Thanks in advance!!!!!!!!!!!!!!
