Not able to run server and primary on different systems

[dcs2020]

Hi,
I am running Server on desktop and running Primary on another system, for the setup in demo/_init.py file I have modified LOCAL with ip address of server and in demo/pinned_primary_template.json file I am modifiying local host with IP address of server but primary is not able to connect to server i am getting error as below:

import demo.demo_primary as dp
dp.clean_slate()

Primary is now listening for messages from Secondaries.
Registering Primary ECU Serial and Key with Director.
Primary will now listen on port 30701
Traceback (most recent call last):

Are you actually able to connect between the systems yourself with netcat or similar? Do you have a host firewall on a system or anything else that may block communication?

Hi Justin,

Thank you for the respone.

Are you actually able to connect between the systems yourself with netcat or similar?
Yes, I am able to ping from one system to another through ssh and ping commands but connection is not happening between server and primary.

Do you have a host firewall on a system or anything else that may block communication?
No, I dont have any firewall I am using open access network system.

Thank you,
Deepthi

The Uptane repository is just a web server. Can you connect to it that way to test?

Hi Justin,

I tried to connect it through nc command but it is not able to connect.

Thank you,
Deepthi

Okay, if you can't connect through nc, then it is a problem with your network setup, not a problem with the Uptane code. You likely have some iptables rules, firewall rules, etc. in place that are blocking HTTP traffic. I'm not sure what to tell you except you'll need to fix this before being able to get Uptane to run. I'd recommend just getting a basic HTTP server / client setup working first and then running the Uptane code.
