However, I suffered from the SSH tunnel being "closed" due to inactivity (depsite the ssh process staying up). So to reach my NAS from the internet, I simply need to create an SSH tunnel between my NAS and my VPS, that reliably stays open all the time (for round the clock access). Therefore, to reach my NAS, I have a VPS (which I rent from OVH for a very small monthly cost), and that has a fixed public IP address. I have a NAS that I want to reach from the internet, I can't use port forwarding because my ISP uses CGNAT (my public IP is not really my public IP, I'm behind another router I don't have any control over). Upstart script on Ubuntu, where /etc/inittab is not available: start on net-device-up IFACE=eth0Įxec ssh -i /path/to/rsaKey -N -o "ServerAliveInterval 180" -R 55002:localhost:22 scriptįor those who don't want to (or) can't use AutoSSH. etc/inittab, to have access to a box shipped and installed in another country, behind NAT, without port forwarding to the box, you can configure it to create an ssh tunnel back to you: tun1:2345:respawn:/usr/bin/ssh -i /path/to/rsaKey -f -N -o "ServerAliveInterval 180" -R 55002:localhost:22 'sleep 365d' sleep 5 done) do not remove the sleep command, ssh may fail quickly and you'll respawn too many processes The interfaces also allow you to remotely stop, start, and update agents.Always use ServerAliveInterval SSH option in case the tunnel issues are generated by expired NAT sessions.Īlways use a respawning method in case the connectivity goes down entirely, you have at least three options here: Ngrok provides APIs and a dashboard UI for you to monitor the health of ngrok agents running in your fleet. Remote checks, stop, start, and updates You can also forward all or some of your traffic events from ngrok to your preferred logging tool. Each subscription can send the events to one or more destinations, such as Amazon CloudWatch Logs, Amazon Kinesis (as a data stream) or Amazon Kinesis Firehose (as a delivery stream).Įvent subscriptions can be configured through the ngrok Dashboard or the ngrok API. Now that your device is integrated to ngrok, you can execute tasks at the ngrok dashboard to operationalize your fleet: Logging Traffic Events from ngrok Įach action that happens in ngrok is published as an event, and Event Subscriptions allow you to subscribe to the events that are interesting in and write them to one or more destinations.Īn Event Subscription is made up of a set of event sources (some of which can be filtered), and event destinations. You can find the correct binary on our ngrok download page. Open a terminal into your remote Raspberry Pi device.ĭownload the latest ngrok binary for ARM. ![]() ![]() ![]() To download and install the ngrok agent on your remote Raspberry Pi device, follow these steps: In this guide, we'll walk you through the process of installing the ngrok agent on a remote Raspberry Pi device, ensuring the agent runs and is integrated into your operating system, restricting traffic to trusted origins, and integrating traffic events with your preferred logging tool. What is ngrok? ngrok is an ingress-as-a-service platform that removes the hassle of getting code online from developers’ plates by decoupling ingress from infrastructure with one line of code, all without provisioning proxies or VPNs. You can get started with a single command or a single line of code. Ngrok allows you to create secure ingress to any app, device or service without spending hours learning arcane networking technologies.
