How to setup PassManJs

1. clone the project
2. if you want a full production deployment host on a domain, then follow these steps
   1. make sure you have the star deployer available (from the ImperialStarDeployer repo)
   2. make sure certain system dependencies are installed, these include nginx and systemd, and an ssl certificate (I use certbot to manage that)
   3. make sure star deployer is aware of how your nginx is configured (here I assume nginx configuration lives in /etc/nginx)
   4. you should have a /etc/nginx/conf.d directory, if you don't then here are the steps to create it
      1. sudo mkdir /etc/nginx/conf.d
      2. then modify the /etc/nginx/nginx.conf and in the "http" section (starting with "http {" and ending with "}")
         • add a line that says "include /etc/nginx/conf.d/*.conf;"
   5. the full path to that conf.d directory should be specified in a project variable for star deployer named "nginx_conf_d_dir".
      • since this is a system variable, I usually include it in the root /.imperial-star-deployer.json variable file
   6. make sure star deployer is aware of how your systemd is configured
      • usually just set the "systemd_etc_path" variable to the path /etc/systemd if that is where your systemd stores its configuration files
      • it is assumed that {systemd_etc_path}/system is where service files are located
   7. make sure star deployer is aware of how your ssl certificate is configured
   8. 2 files are referred to by the PassMan nginx conf file: "nginx_ssl_cert" and "nginx_ssl_cert_key"
   9. I usually run certbot and have it automatically add its certificate paths to a dummy nginx conf file and then copy those paths into these 2 variables
      • on my raspberry pi these paths were the following:
      • nginx_ssl_cert: /etc/letsencrypt/live/isaacsteadman.com/fullchain.pem
      • nginx_ssl_cert_key: /etc/letsencrypt/live/isaacsteadman.com/privkey.pem
   10. make sure star deployer is aware of the domain you are hosting PassMan on by adding a project local .imperial-star-deployer.json variable file
       • all you need to include is {"project_domain": "your domain"}
   11. run {ImperialStarDeployer directory}/star deploy {PassManJs directory}
   12. and now you should be good to go.
3. if you don't need a full production deployment and want to just run it locally, then follow these steps
   1. cd into PassManJs
   2. to get dependencies run yarn install
   3. to build run yarn run build-client && yarn run build-server
   4. to run the server and make the client available to a browser run yarn run start-server

Current Considerations

• avoid DoS attack surface
  • only make changes to the file system after the user is authenticated and request is permitted by server policy
  • ony read user header before client is authenticated
  • also avoids unauthenticated metadata leakage
  • server policy was created primarily to mitigate DoS attack
  • the server may still get overloaded in terms of CPU and network capacity, but the storage on the host will not if you limit account creation and account size with server policy (see class LimitedPolicy in ServerPolicy.ts)
• lock the userLock before any filesystem access
