We have lots of users that use MongoDB through our proxy servers. We suggest you go with the SOCKS proxy using our QGTunnel software.
SOCKS5 is a very flexible TCP level tunneling protocol which works on a per host basis and is compatible with all programming environments.
If you're not sure whether to use the SOCKS proxy, then please check out our HTTP vs SOCKS article.
Please note : This product includes software developed by Inferno Nettverk A/S, Norway. For more information on their software Dante, please see https://www.inet.no/dante/
QuotaGuard Static provides three ways to setup SOCKS5 proxy integration within your app:
- QuotaGuard Tunnel, process-based tunneling program (recommended)
- QuotaGuard Socksify script, routing-based tunneling program
- Framework specific support for SOCKS5
1) QGTunnel is an extremely versatile wrapper script for your process. It allows you to map one or more local ports to route through the QuotaGuard proxy servers. It supports a DNS override mode for protocols that require the hostname stay the same (ie: HTTPS) or to minimize the impact on the code. QGTunnel also supports end-to-end encryption of your tunnel data for protocols that are not encrypted (ie: redis).
We recommend QGTunnel unless you need to route all traffic within the app through the SOCKS5 proxy.
2) QGSocksify is a routing-based tunneling program. It allows for all or some of the outgoing traffic to be routed through the proxy server based on the destination IP or IP range.
3) Additionally, many languages support SOCKS5 proxies natively or via a add-on package.
Please note: The wrapper is not compatible with OSX or Windows. We recommend using a Virtual Machine running Ubuntu for development testing if your main development environment does not run Linux.
To Get Started with the SOCKS5 Proxy Utilizing
QGTunnel, Please Follow These Steps
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
Login to our Admin Dashboard and begin to setup the tunnel.
At the top right, click Settings, then Setup. On the left, click Tunnel, then Create Tunnel. You should reach this screen below.
For example, the example here assumes a MongoDB server.
Remote Destination: tcp://hostname.for.your.server.com:27017
Local Port: 27017
This setup assumes that your remote MongoDB server is located at “hostname.for.your.server.com” and is listening on port 27017 (this is usually the default MongoDB port).
Use the same port for the local port, unless you are using that port or it is below 1024, then you will have to change this to some other port (say 27018).
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.
Note for Clusters
If you are running a cluster, you will need to setup a tunnel (remote destination) for each endpoint and use transparent mode.
For example, if you want to access replicated MongoDB cluster using QGTunnel with 3 replicas located on the hosts: rs01.mongodb.net:52115, rs02.mongodb.net:52115 and rs1.mongodb.net:52115. For this configuration you will need to create three separate tunnels for each host on the port 52115 in transparent mode.
Once this is done, QGTunnel will alter DNS resolution process to resolve these host names to the appropriate loopback address and auto discovery for your replicated cluster should work as intended.
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. MongoDB is usually already encrypted, but you should double check to be sure. 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 a dependency from your system.
3. Change your code (maybe)
You may have to change your code to connect through QGTunnel.
With transparent mode, and matching Local and Remote ports, you should not have to change your code. You can also connect to 127.0.0.1:27017
Without transparent mode, you will want to connect to 127.0.0.1:27017. If you changed the local port, then you will need to change the port number to match.
4. Change your Procfile
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
Before and After:
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb
web: bin/qgtunnel bundle exec unicorn -p $PORT -c ./config/unicorn.rb
Heroku Users: If you do not have a Procfile, then Heroku is using a default setup in place of the Procfile based on the framework or language you are using. You can usually find this information on the Overview tab of the application in Heroku's dashboard. It is usually under the heading "Dyno information".
5. Environment Variable
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, 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 will work.
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.
On Heroku, for example, you enable QGTunnel's debug from the Heroku CLI with:
heroku config:set QGTUNNEL_DEBUG=true
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.
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 Tunnel 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 can be a bit tricky to set up, or debug, so if you have any issues just get in contact with our Support and we'll help you out.
If you have questions, or if this solution doesn’t work or fit your use case, please reach out to us at Support
so we can help figure it out with you.
Working with sensitive data, like HIPAA, Financial, or Personally Identifiable Information (PII)?
Then you will want to check out our QuotaGuard Shield solution, it's the same as QuotaGuard Static, but with stronger end to end security for your requests. We can also help migrate current Static customers to Shield for free, just reach out to us at Support to request assistance.
