Install firefox, open tabs for everything you wish to display, install Tab Slideshow and set it to cycle. https://addons.mozilla.org/en-us/firefox/addon/tab-slideshow/ Then just hit F11 and put Firefox into fullscreen mode, works on Win/Mac/Linux. -- Nat 07531 750292 http://natmorris.co.uk

Two weekends ago EMFCamp took place north of London in Milton Keynes, the UK’s first maker weekend long festival, ran along the same lines as CCC / HAR2009 etc. A small team of us designed the infrastructure for it, we started at the end of May, 3 months in advance. The CCC noc team in Germany were kind enough to lend us their event /19 + /48 + ASN, we built a temporary network spanning from Telehouse East in London Docklands up to a local data centre (Pulsant) in Milton Keynes. Pulsant sponsored us with a 1gb/s L2 circuit from Telehouse to Milton Keynes, we placed a router (c7202+npe-g2) in each decenter. We took on transit in both sites and had temporary membership to LONAP in Telehouse where we connected to their route server for v4,v6 peering and even multicast. Biggest cost was the 2 mile link from the dc back to the festival site, we rented 2 portable 30m trailer mounted masts. A microwave company loaned us some DragonWave kit which ran on 18ghz at 385mb full duplex, this was our primary link and they applied for a UK OFCOM temp telco license for this on our behalf. We also bought a pair of Ubiquiti Nanobridge M5’s for backup, running at about 100mb. We didn’t firewall anything, users were made aware what they were connecting to, there were no passwords on the SSID’s, we had no agenda to monitor traffic. We published abuse email addresses and a number that people could call if required and we would act on it (the RIR contacts for the address space were updated too) Our NOC: http://www.flickr.com/photos/nottinghack/7929611918/ https://dl.dropbox.com/u/74717/2012-08-30%2017.40.26.jpg http://www.flickr.com/photos/ru/7909193016/ http://www.flickr.com/photos/nottinghack/7929909834/ Onsite core and servers http://www.flickr.com/photos/nottinghack/7929611592/ http://www.flickr.com/photos/andy_d/7902260210/ For wireless we deployed a pair of Cisco wireless controllers, all the APs were lightweight and RF allocation was easily managed centrally. https://twitter.com/emfnoc/status/241944863887749121/photo/1 Just like CCC + HAR we deployed portaloo’s / datenklo around the campsite and campers connected up to them for power and Ethernet: http://www.flickr.com/photos/ne0hack3r/7924490940/ http://www.flickr.com/photos/je4d/7924689482/ Sort out kit configuration out well in advance, really glad we did as we spent far longer getting the mast and microwave kit aligned that we thought. Switches, servers were all configured before arriving so we just unloaded and connected things up according to the plan. Avoid NAT’ing anything, speak to a friendly ISP and borrow some address space. We split DNS resolvers, DHCP, monitoring VMs across 3 separate VM hosts just in case one had a hardware failure, don't rely on a single server box.

The RIPE hostmaster would only allocate us address space 7 days before the event started, needed longer than this to begin building out the network which span multiple data centres. Especially with time, access and change freeze constraints due to the Olympics this year. They didn't seem to want to budge on this, easier in my opinion to borrow some off a friendly organisation or ISP than jump hoops with RIPE. Only other option would be to build your infra out in an existing spare /24 you can get hold of - put router loopbacks, point to points etc in there. Then a week before the event attempt to get the larger /19 assignment from RIPE to put your clients in. I wouldn't be happy doing that though, as in my opinion it doesn't leave enough time for any reachability testing / debugging. -- Nat http://natmorris.co.uk http://twitter.com/natmorris

This is good news Nick :) I have spoken to others in the past few weeks who were hoping to raise it at the next RIPE meeting. I am happy to share our ticket details with you off list if it'll help. -- Nat http://natmorris.co.uk http://twitter.com/natmorris
