Setting up PostgreSQL with QuotaGuard Static IP's
We suggest you go with the SOCKS proxy using our QGTunnel software. Here are the setup instructions to get you started.
1) Download QGTunnel
Download and extract the qgtunnel package in the root directory of your app:
$ curl https://s3.amazonaws.com/quotaguard/qgtunnel-latest.tar.gz | tar xz
2) Setup the Tunnel
Click Create a Tunnel. You should reach this screen below.
Remote Destination: tcp://hostname.for.your.server.com:5432 Local Port: 5432 Transparent: true Encrypted: false
This setup assumes that your server is located at “hostname.for.your.server.com” and is listening on port 5432 (the default port).
Use the same port for the local port, unless you are using that port or it is below 5432, then you will have to change this to some other port (_say 5433).
Transparent Mode allows QuotaGuard to override the DNS for hostname.for.your.server.com to 127.0.0.1, which redirects traffic to the QGTunnel software. This means you can connect to either hostname.for.your.server.com or 127.0.0.1 to connect through the QGTunnel.
More information is available on transparent mode as you follow along in these instructions.
Encrypted Mode can be used to encrypt data end-to-end, but if your protocol is already encrypted then you don’t need to spend time setting it up. We have more details on end-to-end encryption as you follow along in these instructions.
Creating the tunnels in the dashboard is for convenience. Please see the last step (Harden Your Setup) for how to remove this dependency from your system.
3) Change Your Code to Connect Through the Tunnel (maybe)
You may have to change your code to connect through QGTunnel.
With transparent mode, and when using the same local and remote port, you should not have to change your code.
Without transparent mode, you will want to connect to 127.0.0.1:5432 (like in this example). If you changed the local port, then you will need to change the port number to match.
4) Change your startup code
Heroku Users: You have a procfile even if it’s not explicitly in your code base. To find it, log into the Heroku dashboard, click on the Resources tab, and you will see a list of your dyno processes. The text you see (like web npm start) next to each one acts as your Procfile if you do not have one explicitly in your code base.
Modify your app Procfile to prepend the QGTunnel application to your standard commands:
web: your-application your arguments
web: bin/qgtunnel your-application your arguments
Heroku Users: You have a procfile even if it’s not explicitly in your code base. To find it, log into the Heroku dashboard, click on the Resources tab, and you will see a list of your dyno processes. The text you see (like web npm start) next to each one acts as your Procfile if you do not have one explicitly in your code base
5) Setup the environment variable QUOTAGUARDSTATIC_URL to be equal to your Connection URL in the Setup page of our dashboard.
If you added us from a cloud provider (Azure, Cloudfoundry, Heroku, AWS, IBM Cloud, Pivotal, etc) then this is usually done for you.
Please note that QGTunnel handles converting the HTTP URL and port to the SOCKS5 URL and port. So either of the connection URLs is fine.
Commit and deploy your changes. Be sure to add
If you are using transparent mode, be sure
vendor/nss_wrapper/libnss_wrapper.so is also committed.
7) (Optional) If problems arise…
By default all fatal errors encountered by the qgtunnel will be logged to your logs.
If this information is not enough you can enable verbose output mode by setting QGTUNNEL_DEBUG environment variable to true and restart the application while watching the logs.
Send any information in the logs (please redact any credentials, including your QuotaGuard connection URL) to our Support so we can help figure out the problem with you.
8) IMPORTANT: Harden Your Setup
This step is highly recommended as we do not have any SLA on our website, which can be out due to maintenance at any time.
By default qgtunnel will try to fetch configuration from the QuotaGuard API, but it also supports local configuration.
You can download a configuration file from the Dashboard by pressing Download Configuration on the Tunnels page.
Place the downloaded file into the root directory of your project under the
.qgtunnel filename, commit and deploy.
With this file your application will not depend on the availability of our website during application startup.
The SOCKS wrapper is not straight forward to set up, or debug, so if you have any issues just get in contact with our Support and we’ll help you out.
