Snabb Lab

Servers devoted to the Snabb Switch project and usable by all known developers.

Want to be a known developer? Sure! Just edit authorized_keys and send a pull request. No fuss.

Guidelines

• Feel at home. These servers are here for you to play with and enjoy.
• Check with the mailing list before making global changes. (Not everybody wants your ultimate zsh config!)
• Don't keep precious data on the servers. We might want to reinstall them at short notice.

Get started

You are welcome to play, test, and develop on chur.snabb.co (and jura.snabb.co). Once your SSH key is authorized (above) you can create a private account like this:

ssh -p 2020 root@lab1.snabb.co  # Login to chur
useradd -G sudo -m myusername   # Create account
su - myusername                 # and now you are in business

See all available ports with lspci | grep 10-Gigabit.

The NICs are dual port cards and the ports of each card are cabled together. So PCI address 0000:xx:00.{0,1} are connected to each other.

(The NICs also have a hardware loop back mode that ca be handy for testing "real" traffic even with only one port and unknown cabling.)

Thanks

We are grateful to Silicom for their sponsorship in the form of discounted network cards for chur. Thanks gang!
