Hi, Just to clarify, this problem is only affecting the machine that we use for carrying out regular Nmap scans on our network. Nmap 5.20 works fine on other nodes within our network and this is a problem specific to the machine I'm using. The machine in question is a virtual machine running on top of VMware ESX. The guest OS of the virtual machine is Red Hat Enterprise Server 5.4. When I run Nmap 5.20 it doesn't see any remote machines (see output below). When I reinstall Nmap 5.00 everything works OK again. Has anyone got any ideas why this particular machine isn't getting on with the new version of Nmap? *** Sample output *** # nmap -sS -sU -A foobar Starting Nmap 5.20 ( http://nmap.org ) at 2010-01-27 08:05 GMT Note: Host seems down. If it is really up, but blocking our ping probes, try -PN Nmap done: 1 IP address (0 hosts up) scanned in 0.60 seconds # nmap -sS -sU -A -PN foobar Starting Nmap 5.20 ( http://nmap.org ) at 2010-01-27 08:05 GMT Nmap done: 1 IP address (0 hosts up) scanned in 0.60 seconds # ping -c 1 foobar PING foobar (10.201.228.46) 56(84) bytes of data. 64 bytes from foobar (10.201.228.46): icmp_seq=1 ttl=64 time=0.257 ms --- foobar ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.257/0.257/0.257/0.000 ms *** End of sample output *** Best regards, -- Ben Dalling email: b.dalling () locp co uk www: http://www.locp.co.uk _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://seclists.org/nmap-dev/
