Sorry to bug you guys again, but nmap is really pissing me off. I need to use this tool as part of my daily security role. (Security Analyst) I've never had any issues with nmap, including up to version 8.2. Now that I've installed version 9.0 it will run ok if I scan a host as a normal user, but if I su or log into root; scanning the same host comes back as 'host seems down'. What gives? I need to run root level scans. BTW...I've tried both versions 3.30 from the 9.0 CD's and version 3.48 from insecure.org. Same results with both!
