Hi folks, I am sending you this email to report a strange bug: ping_sweep.ips --> contains 17 ips The Full TCP and UDP scan finds all 17: nmap -P0 -n -v -iL ping_sweep.ips -sU -sS -sV -O -oA full_scan.tcp -p- Starting Nmap 4.76 ( http://nmap.org ) at 2008-10-18 16:27 IST Initiating SYN Stealth Scan at 16:27 Scanning 17 hosts [65535 ports/host] If I remove -sU it only finds 4 (this is the bug): nmap -P0 -n -v -iL ping_sweep.ips -sV -O -oA full_scan.tcp -p- Starting Nmap 4.76 ( http://nmap.org ) at 2008-10-18 16:30 IST Initiating SYN Stealth Scan at 16:30 Scanning 4 hosts [65535 ports/host] As a temporary workaround I am scanning 1 UDP port on the TCP scan, which works: nmap -PN -n -v -iL ping_sweep.ips -sS -sU -sV -O -oA full_scan.tcp -p T:-,U:53 Starting Nmap 4.76 ( http://nmap.org ) at 2008-10-18 16:31 IST Initiating SYN Stealth Scan at 16:31 Scanning 17 hosts [65535 ports/host] However I should not have to scan any UDP ports, i'm saying "scan these hosts using a SYN Scan and scan all ports" and it should just work (which is not the case). Oddly enough if I perform the same SYN scan for a single IP it works ok: nmap -P0 -n -v 192.168.9.220 -sS -sV -O -oA full_scan.tcp -p- Starting Nmap 4.76 ( http://nmap.org ) at 2008-10-18 16:24 IST Initiating SYN Stealth Scan at 16:24 Scanning 192.168.9.220 [65535 ports] Thanks in advance and please keep up the great work. All the best, 7aW0lf _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
