facebook spying on us?
by Glen Kent 02 Oct '11

02 Oct '11

Hi, I see that i have multiple TCP sessions established with facebook. They come up even after i reboot my laptop and dont login to facebook! D:\Documents and Settings\gkent>netstat -a | more Active Connections Proto Local Address Foreign Address State TCP gkent:3974 www-10-02-snc5.facebook.com:http ESTABLISHED TCP gkent:3977 www-11-05-prn1.facebook.com:http ESTABLISHED TCP gkent:3665 a184-84-111-139.deploy.akamaitechnologies.com:http ESTABLISHED [clipped] Any idea why these connections are established (with facebook and akamaitechnologies) and how i can kill them? Since my laptop has several connections open with facebook, what kind of information is flowing there? I also wonder about the kind of servers facebook must be having to be able to manage millions of TCP connections that must be terminating there. Glen

Hello, Since Sep 7 Google has bounced a specific type of our mails with this message: host aspmx.l.google.com[74.125.43.27] said: 552-5.7.0 Our system detected an illegal attachment on your message.

Cisco 7600 PFC3B(XL) and IPv6 packets with fragmentation header
by Mikael Abrahamsson 01 Oct '11

01 Oct '11

Just thought I'd share some operational info. PFC3B will by default punt IPv6 packets with fragmentation header to RP and route them there, with the obvious performance penalty this incurs. Workaround is to change this behaviour, meaning ACLs won't work for packets with fragmentation header anymore: #platform ipv6 acl fragment hardware ? drop Drop IPv6 fragments at hardware forward Forward IPv6 fragments at hardware PFC3C is supposed to not be affected. A lot of Teredo and 6to4 traffic has fragmentation headers, so this actually is a real problem. We discovered this at our Teredo relay upstream router. -- Mikael Abrahamsson email: swmike(a)swm.pp.se
