This week I attended and event organized by Cisco TAC in Krakow. I’ve been in may Cisco events (Live, PVT, Pint etc.) but It was the first time for me at a TAC workshop and I was curious about it.

Spamhaus and Team Cymru can help providing list of known bad IPs and subnets that should be filtered in our networks.

Hi CLEUR! This year, for the fourth year in a row, I’ve attended Cisco Live Europe . I’ve earned the “Netvet” status, that means my name was on the wall before the keynote, ain’t that great? ;-) Aesthetics apart, this year’s event was the biggest I’ve attended so far, twelve thousands people in a huge venue (for European standards) and a lot of sessions available. Here’s my recap of the event.
