# Install Psono CE

Installation instruction for the Community Edition of Psono, using Psono's combo image which bundles the server, web client and admin portal.

# Preamble

At this point we assume that you already have a postgres database running, ready for connections. If not follow this guide to setup postgres.

# Installation

  1. Create a settings.yaml in e.g. /opt/docker/psono/ with the following content

    # generate the following six parameters with the following command
    # docker run --rm -ti psono/psono-combo:latest python3 ./psono/manage.py generateserverkeys

    Update database credentials / secrets / paths like described in the comments

  2. Test E-Mail

    The most tedious step is usually for me to get e-mail working. To make this step easier, we offer a small test script which will send a test e-mail.

    To send a test e-mail to something@something.com execute:

    docker run --rm \
      -v /opt/docker/psono/settings.yaml:/root/.psono_server/settings.yaml \
      -ti psono/psono-combo:latest python3 ./psono/manage.py sendtestmail something@something.com
    

    If you receive this test e-mail, it should be configured properly.

  3. Prepare the database

    docker run --rm \
      -v /opt/docker/psono/settings.yaml:/root/.psono_server/settings.yaml \
      -ti psono/psono-combo:latest python3 ./psono/manage.py migrate
    
  4. Create a config.json with the following content in e.g. /opt/docker/psono-client/:

    {
      "backend_servers": [{
        "title": "Psono.pw",
        "url": "https://psono.example.com/server"
      }],
      "base_url": "https://psono.example.com/",
      "allow_custom_server": true,
      "allow_registration": true,
      "allow_lost_password": true,
      "disable_download_bar": false,
      "authentication_methods": ["AUTHKEY", "LDAP"],
      "saml_provider": []
    }
    

    Adjust the title and domain of the URLs accordingly.

    TIP

    If you want to configure your admin portal different, them create a second config.json.

  5. (optional) Change domain for login

    You don't see it yet, but later in the login form your username will be a composition of something that the user defines, and a domain, forming the full username that looks similar to an email address (e.g. something@example.com).

    The client will parse the base_url parameter from the config.json. Sometimes you would want to specify a different domain. You can do that by adjusting the config.json as shown below:

    {
      "backend_servers": [{
        ...
        "domain": "other.com",
        ...
      }],
      ...
    }
    
  6. Run the Psono server container and expose the server port

    docker run --name psono-combo \
        --sysctl net.core.somaxconn=65535 \
        -v /opt/docker/psono/settings.yaml:/root/.psono_server/settings.yaml \
        -v /opt/docker/psono-client/config.json:/usr/share/nginx/html/config.json \
        -v /opt/docker/psono-client/config.json:/usr/share/nginx/html/portal/config.json \
        -d --restart=unless-stopped -p 10200:80 psono/psono-combo:latest
    

    This will start the Psono server on port 10200. If you open now http://your-ip:10200/server/info/ you should see something like this:

    {"info":"{\"version\": \"....}
    

    If you don't, please make sure no firewall is blocking your request.

  7. Setup cleanup job

    Execute the following command:

    crontab -e
    

    and add the following line:

    30 2 * * * docker run --rm -v /opt/docker/psono/settings.yaml:/root/.psono_server/settings.yaml -ti psono/psono-combo:latest python3 ./psono/manage.py cleartoken >> /var/log/cron.log 2>&1
    
  8. Setup Reverse Proxy

    To run the Psono password manager in production, a reverse proxy is needed, to handle the ssl offloading and glue the Psono server and webclient together. Follow the guide to setup reverse proxy as a next step.

# Note: Installation behind Firewall

If you have put your installation behind a firewall, you have to whitelist some ports / adjust some settings, that all features work:

  • Incoming TCP connections (usually Port 443) from clients to servers
  • Incoming TCP connections (usually Port 443) from fileservers to servers
  • Incoming TCP connections (usually Port 80) from clients to servers (will do the redirect to https)
  • Outgoing TCP 5432 to database server
  • Outgoing TCP / UDP 123 connection to time.google.com: Psono requires a synced time for various reasons (Google Authenticator, YubiKey, Throttling, Replay protection, ...) Therefore it has a healthcheck, to compare the local time to a time server (by default time.google.com). You can specify your own timeserver in the settings.yaml with the "TIME_SERVER" parameter. If you are confident that your server always has the correct time you can also disable the healthcheck with "HEALTHCHECK_TIME_SYNC_ENABLED: False".
  • Outgoing TCP 443 connection to api*.yubico.com: Psono validates YubiKey OTP tokens against the official Yubikey Servers. You can use your own YubiKey server with the "YUBICO_API_URLS" parameter in the settings.yaml
  • Outgoing TCP 443 connection to api*.duosecurity.com: Psono initiates connection to the Duo api server, whenever someone uses Duo's 2 Factor authentication. Psono also supports Duo's auth proxy duo.com/docs/authproxy-reference by configuring DUO_PROXY_HOST, DUO_PROXY_PORT and DUO_PROXY_TYPE
  • Outgoing TCP connection (usually 25, 465, 587 or 2525) to your email server
