Migration Notes from COSMOS 4.4.x:

To upgrade to the latest version of COSMOS, run “bundle update cosmos” in your COSMOS project folder.

Modify you system.txt files to:

  1. Make sure you have a X_CSRF_TOKEN line with a unique value (anything will do, just change it)
  2. Change all LISTEN_HOST settings to 127.0.01 unless you need connections from external hosts
  3. If you know only specific external hosts will be connecting, add ALLOW_ACCESS lines for each
  4. Only add ALLOW_ROUTER_COMMANDING if you are chaining CmdTlmServers (that need to send commands), or you are receiving commands through routers
  5. Only add ALLOW_ORIGIN <Address of webpage>if you expect COSMOS to be accessed from a webpage
  6. Add ALLOW_HOST :7777, etc if you expect the COSMOS APIs to be accessed from external computers. Otherwise it will only accept connections that have a HOST header set to localhost
