Sounds like you'll fit right in!

I have fond memories of an early LINX meeting etiquette that required 
any participant who allowed their mobile to ring audibly during the 
meeting to buy all the attendees a beer each.
As attendance reached 50+ that became a very serious issue! But I'm 
not allowed to talk about *those* LINX meetings...too much...

Hmm since I used to regularly buy everyone a beer after the meeting
finished, perhaps I should just do that again and this time I'll just sit
in the meeting happily taking calls all day long. Forfeit accepted!

 Interesting timing - we've also been seeing a big increase in the

 automated  ( cheap!) online 'booter' services (presumably
 instigated by students who have had enough of their IT lessons).

If you are seeing attacks against schools and Janet is upstream -
please let us know as and when it occurs. Even if all that we do (and
we try to do a lot more) is add it to our statistics it's still
valuable to build up a picture of activity for the rest of the community.

seen QOTD (UDP 19).





Yep, one that hit us the other week was UDP Chargen. After seeing the 
source port in flows, I tried a few of them on TCP 19 as well, and to my 
surprise, there it was.  And there was me thinking Chargen was a thing 
of the 80's!


It'd be nice to be able to automatically pull the full lists from these 
various scanning projects to use in statistical analysis as part of DDoS 
mitigation (i.e. if my traffic has just shot up and the majority of it 
is coming from IPs listed in these databases, I can take a pretty fair 
bet at what's happening and start to rate limit or temporarily block 
these sources).  Anyone know if there is an interface for automated 
downloading of the raw data? Is anyone involved in these projects on 
list?  It looks like you can request the data manually at the moment.


It'd also be good to discuss merging data from these projects into an 
upstream 'open-generalbadstuff-project'.


Cheers,
Robin

It would also be useful to be able to run resolver scans via ASN or larger 
block reports too. Limited to a /22 takes a fair old while.
