IPv6 MLD (Multicast Listener Daemon) snooping is the equivalent of IPv4 IGMP snooping.
Switches snoop this traffic so that they can tell which ports on a switch are interested in particular streams of multicast traffic.
I installed the new code on our GrangeNet LAN routers and switches.
I think it worked, but I think it's too hard to tell if the routers aren't running IPv6 multicast. Very frustrating!

Guess what! The ink went straight through onto the polished wood dining room table!
Quick! How does remove 3mm wide Sharpie marks??

While the computer was booting we tried:
Windex -- didn't move it.

The Sharpie FAQ wasn't helpful:
General Rules:
1) Treat stains as soon as possible. Fresh stains can be removed more easily than old ones.

* Also try AMODEX STAIN REMOVER for permanent ink: Amodex Products, P.O. Box 3332, Bridgeport, CT 06605, Phone:(203) 335-1255
Googling for remove sharpie table turned up Permanent marker on dining room table.
Does anyone know a safe way to remove permanent black marker (sharpie) from a wooden dining room table? I have read that nail polish remover works but worry that it will destroy the finish on the table. Thanks!

Well, i was watching my little sister and she colored all over her self and my older sisters desk with BLUE permanent marker, and i took it off Easly with TOOTHPASTE and a wash cloth. I'm Not kidding i thought my mom would kill me, but i used the toothpaste and i scrubed hard!! wow i love that! DIDNT RUIN DESK!
(It also had a few othe suggestions like M30 Stain Remover, hair spray, Goo Gone, and anti-bacterial hand gel that we didn't try.)
Anyway, Toothpaste, on a damp paper napkin removed the marks from the table just fine. Didn't scratch the surface. There must be a fine abrasive in toothpaste.

From Norman Koren's Printer calibration page: I found a nice image on The Digital Dog's website PrinterTestfile.jpg.hqx [ No DNS for digitaldog.imagingrevue.com at the moment ... ] I needed to unpack this file on Linux using programs from "macutils".
$ hexbin PrinterTestfile.jpg.hqx
$ ls -ltr
