 00:28 < Sebastian> nickm: going to bed in a minute. Here's what I have so
 far:

 00:29 < Sebastian> 14 ssl handshake failure (in SSL
                    routines:SSL3_READ_BYTES:SSL3_ST_SR_CERT_A) messages.
 They
                    all come from unique IP addresses.
 00:29 < Sebastian> none of those are relays.
 00:29 < nickm> Sebastian: just walked in the door.  Feel free to
 summarize.
                Okay if I copy-and-paste onto trac?
 00:30 < Sebastian> some of them are very similar, which makes me think
 that
                    they might be on dynip and got a new IP which triggered
 a
                    new request
 00:30 < Sebastian> yes, please do

 00:30 < nickm> ok
 00:30 < Sebastian> one sslv3 alert bad record mac (in SSL
                    routines:SSL3_READ_BYTES:SSL_ST_OK) message
 00:31 < Sebastian> this one came from a relay
 00:31 < Sebastian> at a university
 00:31 < Sebastian> so I think they are messing with things
 00:31 < Sebastian> no other things to report yet.
 00:32 < Sebastian> (well, got a few of the known connection_mark_for_close
                    messages, but those seem pretty isolated.
 00:32 < Sebastian> )
 00:33 < nickm> Can you tell me which relay so I can experiment?

 00:34 < Sebastian> gurgle ( gurgle.cs.uwaterloo.ca, ip address
 129.97.74.17 )
 00:34 < nickm> oh interesting.  I wonder if they're running any unusual
                performance hacks.
 00:35 < Sebastian> orport 5011
 00:35 < Sebastian> feel free to experiment with fluxe3 too
 00:35 < Sebastian> I'll keep it running
 00:38 < Sebastian> ok, I think I'm going to bed. Laters
