Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hello, I'm not sure if this belongs in freebsd-stable, -security, or -misc, so I'll take my chances and post it here, in -stable. I was fooling around with nmap one day, reading the man page, and stumbled upon the -D, decoy option. So, to test it out, I nmapped one of my boxen with the decoys of www.daemonnews.org, www.slashdot.org, and acs.bu.edu. It worked, and it was kind of neat. However, after it completed the nmap, I am now unable to connect to www.slashdot.org, or www.daemonnews.org. So I began investigating a bit. Heres some of the weird things that are happening. The internal interface on my router has two ip addresses, 169.69.7.1, and 169.69.6.1. I have all of my computers using the gateway 169.69.6.1, however, when I traceroute, it sends the packets to its alias 169.69.7.1. Still works though. This is what happens when I traceroute www.slashdot.org, and the same for acs.bu.edu, or daily.daemonnews.org. Thankfully, I can connect to acs2.bu.edu and so on. kaworu@teqnix kern> traceroute www.slashdot.org traceroute to slashdot.org (64.28.67.48), 30 hops max, 40 byte packets 1 169.69.7.1 (169.69.7.1) 1.440 ms 1.439 ms 1.387 ms 2 149.112.50.65 (149.112.50.65) 4.668 ms 3.730 ms 3.560 ms 3 * * Here is the output from netstat -nr on my router.
