Barrier: Help setting up? Limited documentation.

[chriselrod]

Operating Systems

Server: Antergos (Linux x86_64)

Client: Clear Linux

Barrier Version

On both Client and Server:
flatpak, 2.2.0-snapshot-53ebc47a
Build date: Saturday, January 12, 2019

Steps to reproduce bug

1. Install barrier on server using flatpak.
2. Install barier on client using flatpak.
3. Launch barrier on server. Use default configuration settings.
4. Launch barrier on client. Enter local ip address of server, (re)check Auto config.
5. Start server, then start client.
6. See a bunch of ssl errors in log. Disable ssl on server and client. Apply/restart both.
7. See a bunch of connection refused messages in log.

With Enable SSL:

Other info

I do not know how to work around this. I do not know much about networking, beyond simple things like openssh server.
Therefore, this prevents me from using Barrier entirely.

Am I supposed to configure some things, like making the server listen on port 24800? How is the server supposed to recognize the client's name?

I am writing this comment with the host keyboard on the client computer. :)

How to fix my problem:

1. On the server, click the Configure Server... option, and add another screen. Give that screen the client's name.
2. I am not sure if this is still an issue: https://symless.com/forums/topic/2550-server-refused-client-with-our-name/ but I gave my client a name more sensible than "clr-7b12d38c3bf247448c96becf747df83f" anyway.

That is all it took!

I'm closing this issue so as to not distract from other unresolved issues. Even though just how easy it was to actually get things working reinforces the idea that adding a little more documentation/to the wiki may help a lot.
Or maybe I'm just a little slow to figure things out on my own, ha ha.

Initial impressions are: seems awesome!

1. add another screen. Give that screen the client's name

When I tried that it only started refusing the connection on the basis that the server already had a client with that name

This is a really important note! I was just going from two Windows machines and thought this was a firewall issue or something. So glad I found this, thanks!
