Background
As an operator I want to clearly define a minimum set of requirements to be met before a node can become part of SCIONLab as infrastructure node.
State
The current version of
scion-tutorials/content/join_infrastructure.md
is highly outdated mainly (but not only) in parts about operating system and firewall rules.[A] There also statements which we don't want to have, like
you can start as small as dedicating only a simple commodity PC
. In this case user should be running an user AS as this is highly probable a commodity PC will be an old&cheap machine under someone's desk without any operational support at all.[B] Currently we require
minimum of 4 GB of RAM
. This is not enough in many cases and causes us to run at the edge what also increases operational costs in case strange things happen. Nowadays a reasonable requirement should be 8 GB of ram and at least 4 vCPUs.[C] A model operating system for the infrastructure node is currently Ubuntu 18.04.
[D]
border router node(s) must have a public static IP
should be extended to a requirement where all the nodes have static IPs. Otherwise that would mean for intra-AS communication we need to deal with dynamic IPs what sounds crazy.[E] The sentence
it may be enough if a firewall allows return traffic to the same port
sounds very vague. For people dealing with firewall configurations it's more than enough to be told something like "incoming traffic from X to Y over port Z"[F] Address ranges for management SSH traffic are very incorrect.
[G] The last option in
we can also operate the connections over a tunnel, e.g. OpenVPN, Wireguard or SSH tunnels
should be removed. I cannot imagine operating anything more than "debug & very temporary test" via SSH tunnel as this thing is not properly deployable, monitorable nor operatable.Further improvements
As a further enhancement I want to provide a "hardened configuration" in case there is a business requirement to run in a harsh/strict environment, given the value is higher than investment needed.
