List of things to do, to pack and tips on attending a congress, especially Chaos Communication Congress.
This list is irregularly updated (and pushed). You may want to refresh regularly. :-) Pull requests are welcome!
General considerations to make the congress a worthwhile experience for everyone, humans, robots and aliens alike. You'll also find a list of all the nice humans who have contributed to this list at the bottom.
- Be excellent to each other.
- If you spot somebody not being excellent to someone else, remind them to be excellent and have them apologi(s|z)e to the insulted part(y|ies), but only if the insulted wish to be apologi(s|z)ed to. Sometimes the insulted party will just want to move on and not have any further contact with someone who was coarse to them.
- If you don't want to be called $swearword, don't behave like one.
- Help each other out.
- Read the “Anti Harrassment Policy” and live by it. :-)
- Ask if it is ok to take a picture BEFORE taking the picture.
Things to do before traveling
- Charge ALL the batteries!
- Make backups.
- bonus points for even testing restore
- Update all the software on your devices.
- You might want to empty your drives to make room for some COMPLETELY LEGAL media files that might be shared
- Put your name on your stuff, especially on things you’ll likely lend to someone (power strips, cables etc). Twitter handles make excellent name tags because people know how to contact you right away. Prefer permanent markers over stickers, for theft reasons.
- You DID make backups of all your devices, didn't you? That includes portable computers, servers, mobile phones, tablets, navigation devices, wrist watches and all your other $gadgets.
- Store the backups not only on the device your backing up or another device you’re taking with you. A swiss bank locker is good, if you have one.
- Send a pull request to this list for all the things I did not think of.
- Feed the guinea pigs.
- Water your plants.
- (optional) Create account in the congress wiki, add your projects and find your assembly.

Securing your devices
All security measures for devices on public Internet networks also apply here – threats might come from untrusted devices within, as well as from maleficent third parties outside the Congress network.
Read the How to survive guide in the Congress Wiki. There are many excellent tips in there.
Make fresh backups of ALL the devices you bring to CCCongress. Test that you can actually restore data from those backups!
Make sure you do have set a BIOS or EFI Password to prevent booting from a live CD to attack your system.
Full disk encryption
Activate full disk encryption with pre-boot authentication. (Mac: Activate FileVault.)
You did make fresh backups of all your devices, did you?
Check that all your server services are using proper TLS. See bettercrypto.org for help on how to properly configure your servers. (Mail, Web, VPN, SSH, etc.)
Have at least one trusted, working and tested VPN endpoint available for tunneling out of the congress network. If you don't have your own VPN server at your disposal ask friends you trust to help you out. If you do, ask your friends if they need a VPN endpoint and share!
- iodine (DNS tunnel for those pesky for-pay captive portal WiFi networks)
Also have those tunnels configured on ALL the devices you intend to use, and have it tested. That includes your laptops, phones, tablets, servers, fridge, etc.
It is not recommended to connect your smartphone to the congress wifi, if you still can't resist, here are a few things to consider:
- Make sure that it's not a 802.11b device, as it would slow down the complete wifi network.
- Disable all synchronization services, as they might be using plaintext.
- Disable all auto-discovery services (network music players, remote control apps, etc …).
- Make sure there are no known exploits for your device (not that unknown-to-you exploits wouldn't be a possible risk as well…).
- Turn off push notifications.
- Update your apps, especially your browser.
- Use a VPN tunnel if possible.
- Use a Firewall and only allow the (few) services you trust.
- DroidWall for Android (root required)
- If you don't have a VPN tunnel available, you can use OnionBrowser to surf via tor (which may be it's own kind of risk).
- Set your GSM network selection to manual or you might end up connected to a rogue GMS network by somebody.
If you are unsure that there might still be some services running and transmitting plaintext data, do not connect.
PrePaid SIM Cards
Make sure you get a right sized SIM card for your GSM mobile phone! If you need help with buying a SIM card, ask a local for assistance. They're friendly!
For when you return home
- store chocolate at home as an post-event depression antidote
Thanks for being awesome
