Re: bizarre connection list to tor's DirPort

sounds strange

If it was my connection, I would fire up a network sniffer and see what's in those requests.
If it continues and you don't feel comfortable with it, filter out that IP on your firewall.

If you do see something unusual in those request, could you be so kind to post a dump file (pcap format) of the traffic (filtered by that IP of course) so the rest of us can take a look? :)

legitimate?  Or should I treat it as an attack of some sort and respond by
blocking packets from that system at my router?
