I don't get it--it appears nmap is broken. Perhaps I'm overlooking something obvious, but any thoughts appreciated...
An nmap scan gives me this: $ sudo nmap 208.139.x.x Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2006-02-03 19:45 MST Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 Nmap finished: 1 IP address (0 hosts up) scanned in 2.109 seconds Which I follow up with a: $ ping -c 5 208.139.x.x PING 208.139.x.x (208.139.x.x): 56 data bytes 64 bytes from 208.139.x.x: icmp_seq=0 ttl=239 time=91.979 ms 64 bytes from 208.139.x.x: icmp_seq=1 ttl=239 time=84.497 ms 64 bytes from 208.139.x.x: icmp_seq=2 ttl=239 time=82.354 ms 64 bytes from 208.139.x.x: icmp_seq=3 ttl=239 time=87.825 ms 64 bytes from 208.139.x.x: icmp_seq=4 ttl=239 time=85.699 ms --- 208.139.x.x ping statistics --- 5 packets transmitted, 5 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 82.354/86.470/91.979/3.295 ms Running while the above is happening, tcpdumps yield: $ sudo tcpdump -nqi pppoe0 src host 208.139.x.x and dst host 209.180.x.x tcpdump: listening on pppoe0, link-type PPP_ETHER 19:45:49.671358 208.139.x.x > 209.180.x.x: icmp: 0 0 19:45:49.674068 208.139.x.x.80 > 209.180.x.x.57989: tcp 0 (DF) 19:45:50.683407 208.139.x.x > 209.180.x.x: icmp: 0 0 19:45:50.691346 208.139.x.x.80 > 209.180.x.x.57985: tcp 0 (DF) 19:46:00.565862 208.139.x.x > 209.180.x.x: icmp: 0 0 19:46:01.565834 208.139.x.x > 209.180.x.x: icmp: 0 0 19:46:02.573631 208.139.x.x > 209.180.x.x: icmp: 0 0 19:46:03.589132 208.139.x.x > 209.180.x.x: icmp: 0 0 19:46:04.596986 208.139.x.x > 209.180.x.x: icmp: 0 0 $ sudo tcpdump -qni pflog0 tcpdump: WARNING: pflog0: no IPv4 address assigned tcpdump: listening on pflog0, link-type PFLOG I'm not certain where to look next.
