Look at this video where Jerry Bruckheimer talks about how important IP- video and voice communication is for movie production:

TG13 goodiebag

09 May 2013, by Marius from Tech:Net

We are legally late out with the goodiebag this year. :/

Hope you nice people can forgive us for that 🙂

It is packed and uploaded to the ftp:
ftp://ftp.gathering.org/TG/2013/Tech/TG13-netconfig.zip

We are sorry to inform that the VSS configuration fell between two stools.
If you want to learn more about VSS and configure it, look no further than here:

This one is also nice:

Random nice illustration 😉

Status update; 400 Gigabit VPN

11 Apr 2013, by Marius from Tech:Net

Thanks to all of you who were interested in the VPN.

We wished that this could have been a reality, that would have been cool.
But alas, our speculations and wishes became this years aprils fool 😛

We love you all! 😀

It’s over one year until next TG:

We will install 400Gbps VPN for our participants during the next months.

This way everyone can be connected, on high speed VPN, and get the TG-feeling up till TG14 🙂

Emulate the TG13 network on your own computer

30 Mar 2013, by Martin from Tech:Net

To help you get started on your lab environment, we built the IPv4 topology implemented at The Gathering in GNS3 for you to play with!

The Gathering topology

We did not include MPLS, VRFs and multicast in this lab configuration because it is not relevant to the CCNA objectives. The physical topology is already set up and cabled, so feel free to configure this on your own! We will upload our configs at http://ftp.gathering.org after TG13 if you want some reference.

These are the steps you need to follow in order to get this up and running on windows:

Download GNS3 from sourceforge

After the installation is complete, get a hold of the Cisco images. In this project, the following images were used:
c7200-advipservicesk9-mz.124-15.T10.image (ISP)
c3725-adventerprisek9-mz.124-15.T14.image (everything else)

Unfortunately we cannot provide these images on our website due to licensing issues.

Download the GNS3 project from our FTP server, extract it and place it on your C:\ drive
http://ftp.gathering.org/TG/2013/Tech/GNS3.zip
Place the Cisco IOS images in C:\GNS3\IOS\
Start GNS3 and make sure that you idle PC values are set. You do this by right-clicking the router after it has been powered on, and then click “idle pc”. This will make GNS3 calculate the values for you. Read more about how to do this on [http://www.gns3.net/gns3-simplest-topology/

Click file->open and select “C:\GNS3\The Gathering 2013\topology.net”

This should get you up and running. Have fun – and don’t be afraid to ask questions!

Fun facts

29 Mar 2013, by Mathias from Tech

Some fun facts from us…

Link up/down

Our D-Link access switches have logged 133,184 link up-events and 128,996 link down-events.

Some switches have more link up-events than others (x-axis is switches, y-axis is count)

This may be reboots, cables unplugged and plugged back in, eventual power outages and other things.

Access lists

Our access lists have protected the D-Link access switches against 25,670 connection attempts. This is probably random port scans.

There is an obvious glitch Wednesday night…
This shows temperature from both inlets and outlets as well as some chips!

Lowest temperature reported from nocgw is 15 degrees Celsius. No wonder we were freezing 🙂

Spanning tree

Spanning tree on the D-Link switches have blocked 11 loops.

Stats and monitoring

28 Mar 2013, by Mathias from Tech

As some of you know we have a couple of nice systems for statistics and monitoring.

We use Weathermap for the big picture:

It’s available at http://stats.tg13.gathering.org/

Our good friends in Tech:Server have created their own monitoring system. Most of the system is not really useful for anyone else, but they have made some of it available for the public.

NMS can be found at http://nms-public.tg13.gathering.org
