Network
From Chaos Communication Camp 2007
The Camp Network provides Internet access for everybody.
There will be enough bandwidth to satisfy any needs - every host will get an public, routable IPv4 and/or IPv6 address (as in: no NAT).

[edit] Setup
We are going to set up:
- a huge fiber backed (10 Gbps) network at the site.
- Distribution of wired network on-field is done in part by using Datenklos.
- Multiple independent Internet uplinks from various providers in Berlin.
- 300 Mbps uplink
[edit] Access
[edit] Wired
In order to get connection to your nearest Point of Presence, it is also wise to bring at least one long (as in 20m++) Category 5 Ethernet cable.
Don't forget to bring enough switches or hubs to cover your internal networking needs and a PDU to plug it all in!
[edit] Wireless
The area will be covered with two separate WiFi-networks:
- 2.4 (b/g) + 5 GHz (a) infrastructure
- Wireless:Freifunk (ad-hoc Meshnetwork)
However, camp is nontrivial for wlan, we recommend not to rely on it. We DON'T have enough spectrum for even somebody! WiFi is a shared medium, please don't forget to bring and use your cables!

The Hackcenter offers a public place to operate your machines.
[edit] Safer Surfing hint
Specify a fixed ARP Address: "arp -s 00:0C:DB:FD:23:00" Install Squid/another Proxy at home, block it's port from the Internet. Do "ssh -L 3128:localhost:3128 user@your.host.net" Change your proxy in your browser to localhost:3128 Test it by going to http://checkip.dyndns.org
- Simpler: Do "ssh -D 8000 user@your.host.net", and point your browser to socks proxy at port 8000 localhost.
