Description (last modified by Bill Fenner)


MAC 00:19:d2:7f:a6:52 is advertising bogus v6 prefixes and routers in 
the wireless and should be killed:

11:22:29.254248 00:19:d2:7f:a6:52 > 33:33:00:00:00:01, ethertype IPv6

ok] icmp6: router advertisement(chlim=0, O pref=medium,

(len 112, hlim 255)

I'm also having major wireless usage problems with 802.11b w/ SSID on 
AP 00:1A:1E:8E:7F:C1 (near convention 1), but that's probably 
unrelated.  Wires in terminal room are great though)

We noticed this guy yesterday but for some reason couldn't follow through on blacklisting him.

It's blacklisted now. He was located in one of the Ballroom rooms at the time (BSSID 00:1a:1e:8e:da:61). Hopefully he will come to the NOC to solve his connectivity issues.
