I’m trying to set up a remote connection to my Jetson Xavier AGX since I want to work from home sometimes and my Jetson stays at University.
I’ve followed this:
My Jetson Xavier is connected via Ethernet.
And My local host pc is connected via wifi to the university’s wifi (I eventually intend to use a VPN to connect from further away)
Grabbed the eth0: inet 192.168.192.***
However when I go on VNC Viewer and type in that IP it says “time out waiting for a response from the computer”
Addresses in certain ranges are “non-routable”, meaning the internet won’t work with those. These are private subnets. Anything in the range
192.168.255.255 cannot be accessed over the internet. This means your device is talking to a router, and it is the router itself which has the public routable address.
In order for such a thing to work from the outside world the router would have to be set up to forward the correct ports to that particular device. If this is a university router, then it is unlikely they are going to give you the admin access needed, nor would they be likely to set up specific ports to forward to your device. The only way to talk to the device would be with another device inside of the subnet.
It would be possible for you to pay for some sort of dynamic IP service. In that case your Jetson would have to connect to that, and then from the outside world you’d connect to the dynamic DNS service.
Hmmm but when I’m connected trough a VPN doesn’t it count as me being in the subnet?
Do you know where I can learn more about
“It would be possible for you to pay for some sort of dynamic IP service. In that case your Jetson would have to connect to that, and then from the outside world you’d connect to the dynamic DNS service.”
I’m still looking for some solution to remote work
There can be many subnets.
It’s likely that the Wifi you’re connected to, and the wired network you’re connected to, are on different subnets, and they are not routable between each other.
First, make sure that you can “ping” or “ssh” to your computer from the other computer. Once that works, you can start setting up VNC. To make sure you can ping or SSH between them, you will need to know which subnets each computer is on, and how the routers are configured. This may be obvious in some cases, and require talking to several levels of IT escalation support for whatever school/enterprise you’re in, in other cases.
No, a VPN will operate in a subnet, but the subnet will be cut off from the internet if it is non-routable. It is fine if the other end of the connection is operating locally on the same router, but over the internet it is not possible for a non-routable address to traverse.
Does your VPN at the Jetson side initiate a connection to an outside internet server? If so, then this works, but you’d talk to the outside server and not the non-routable net.
You can search Google for “dynamic IP service”.
