rmfakecloudctl: set-upstream does not validate that URL is valid

[loughnane]

Describe the issue Upon installation status is listed as Status: enabled (failed) on RM1

To Reproduce Steps to reproduce the behaviour:

1. Install toltec per instructions at https://toltec-dev.org/
2. opkg install rmfakecloud-proxy
3. rmfakecloudctl set-upstream 192.168.1.100
4. rmfakecloudctl enable

Expected behaviour I expected the status to be enabled (active)

Screenshots

Device information (please complete the following information):

• Device: reMarkable1
• OS version: 2.15.1.1189

Additional context

Installing on two RM1s. The first installation went swimmingly and is working just fine, but I get a Status: enabled (failed) on the second RM1 device. My server is also playing nicely with an RM2.

Looking in log.txt I see an error about not having a device token

I'm not sure what to do. I've tried reinstalling (I'm on 2.15.1.1189) and like I said the install worked well on the other RM1. Any suggestions on where to look?

What does systemctl status rmfakecloud-proxy output?

Another thing I just took a peek at was my /home/root/.config/remarkable/xochitl.conf and my deviceeToken and UserToken are null. On the devices that work they're populated. Not sure why.

devicetoken=@ByteArray()
UserToken=@ByteArray()

The device token is unrelated to if the proxy is able to run or not. The issue you have right now is that the proxy isn't running, so the device isn't able to communicate with your rmfakecloud instance.

What happens if you try to run /opt/bin/rmfakecloud-proxy -c /opt/etc/rmfakecloud-proxy/config manually? I would expect it to crash, but I'm surprised at the lack of output in the logs.

Got it. Here's the output.

invalid upstream address: parse "192.168.3.100:8000": first path segment in URL cannot contain colon

Oh, you should set your upstream address to be a valid url. I assume it should be http://192.168.3.100:8000

[loughnane]

Oh my goodness. That's it. Thanks. :man_facepalming:

[Eeems]

Oh my goodness. That's it. Thanks. 🤦‍♂️

No worries, this does show that rmfakecloudctl should do a tiny bit of validation on the URL provided and give a bit of insight into why it isn't valid if you miss something it expects.
