Yup.. they're all "ANY" requests. The varying TTLs indicates that they're most
likely spoofed. We are also now seeing similar traffic from RFC1918 "source"
addresses trying to ingress our network (but being stopped by our border
filters).
Looks like the kiddies are playing

Hi All,
I am wondering if anyone else is seeing a sudden increase in DNS attacks
emanating from chinese IP addresses? Over the past 24 hours we've seen a
sudden rash of chinese IPs attacking our DNS servers in the order of 5 to 10
million PPS for periods of 5 to 10 mins, repeated every 20 to
Hi All,
Apologies if off topic, but hoping that one of you gurus out there might have
some tips on this.
I have a rather "unusual" application for DNS which I need to figure out a way
to make it work, but running into authority issues.
Basically, I have a "fake" server running on a private n
Hi All,
I have an XMLRPC server/API that I implemented (written in perl) to manage most
of the cisco kit on the network, with most of the "worker" methods using
Net::Telnet::Cisco. Our new datacenter, however, has Cisco Nexus equipment
which totally breaks the API since Net::Telnet::Cisco do

OpenSolaris ILB is open solution ;)
but yea, that's what we've started looking at -- hence LVM / HAProxy as well..
(though LVM is IPv4 only, and HAProxy is NAT only for IPv6)
does relayd support UDP as well as TCP or is it layer7 only like HAProxy ?
In the case of ILB, I'm not convinced that it
Dear Colleagues,
I've been scratching my head over this for the past couple of months and have
come up with blanks, and several weeks of scouring various resources on the net
have not yielded anything more fruitful.
I'm looking at server load balancing for IPv6 and specifically need DSR (direc

Hi all.. this one seems to have stumped even the community forums on
CCO ;) Anyone else seen this behaviour? (It's not actually a problem
as such since the MEC port-channels are actually working fine, just
unexpected the way that it has done it...)
We have a few paris of VSS running, and having
Thanks to all on this.
I've pretty much mitigated this by creating a VSS-ized version of the
interface configs (chassis/slot/port) which I can then re-inject back
into the system config after conversion.
Shame that switch1 keeps its config and simply renumbers the interfaces,
but switch2 just sa

This one is alarming, especially given that there may well be some

Hi All,
Trying to find an answer to a single technical point concerning a
migration of a fleet of Catalyst 6500's to VSS-1440.
I've had a scan through the documentation on CCO (whitepapers, config
guides, migration guides, etc.) but cannot find anything dealing with
this one specific point.

Thanks Justin... will give it a shot; hopefully they're relatively
rapid :)

Hi All,
Would anyone happen to have an operations contact at Facebook by
anychance? Our systems are being overwhelmed by a facebook application
that we were neither aware of nor condoned.
Thanks in advance.
