Mouse Without Borders can't access other computer on LAN

Problem: Mouse Without Borders can't work. It runs on two computers and allows for use of the same keyboard/mouse across both. I've isolated it to Covenant Eyes installed on my work laptop stopping functionality. 

LAN traffic should not be impacted by Covenant Eyes but it is. Since this is LAN traffic, I think that this behavior would be encountered in other applications from other users, not merely users of this application. Both Covenant Eyes and Mouse Without Borders are a little light on documentation so I really don't know how they do their job at a technical level.

Would like to figure out why this is happening and what can / cannot be done about this.

Hello Byron,

Thank you for contacting us and I apologize for the issue you've been experiencing with Covenant Eyes and the Mouse Without Borders software. I am not too familiar with how the Mouse Without Borders software works so I've shared your issue with our developers and they should be in contact with you soon.

Best regards,
Annelise

It's probably likely that, because this is a LAN based application, that they are using UDP packets to communicate telemetry information. It's also possible that the application is using some unconventional IP ports for communication as well.

This would, of course, presume that CE is acting as an Internet Firewall, and I was not under the impression that this was a "feature" of CE.

Please illuminate!

It uses TCP for the application itself as an option and that's a checkbox so you could use UDP. But I realized you said telemetry information... that is not relevant to the core functionality of the application not working, right? If I understand that's a red herring to the issue of the software not working.

As for the unconventional IP ports? You mean just a normal PORT right? 

CE doesn't act as a firewall but it has interfered with P2P connections with some Steam games in the past. For me, it was Street Fighter V, it tries to connect you in online matches to a peer.


Appreciate the brainstorming but it seems none of the points you brought up are relevant except for the part about the "firewall" nature of CE that it seems to be doing. I know it used to mess with hostfiles and it can block internet access if you're not signed in.

Comments about the actual nature of CE's behavior would be welcome.

Ah! Sorry, telemetry is what we call the data sent from a sensors or measurement devices that is sent upstream to an application that will act on that information. A mouse is classic example of a sensor that communicates telemetry information on it position, velocity, etc, to it's application - the mouse driver.

By unconventional ports, I refer to destination ports that fall outside of the standard defined ports. A list is here on Wikipedia:

If CE is interfering with P2P connections, then it is absolutely acting just like a firewall, and blocking certain connections. That's exactly what a firewall does.

Gotcha. Something interesting to you might be my experience with it interfering with P2P connections before.

I isolated it to CE since I tested with it installed and uninstalled multiple different days.

After some point in time running the most recent version of 7.x of CE, I stopped getting P2P connections in Street Fighter V since the lag made the game playable with real people online.

I called support indicating that CE was isolated out and I was directed to install 5.2.106 which I am running now which I was told over the phone "is one of our most stable versions and seems to resolve issues with a variety of Steam games".

The most recent version has that same sort of generic comment but I'm not going to test with this much information since going from 5.2.106 --> 7.2.10 --> 5.2.106 would be a waste of time if my issue still is there.

Windows Version 7.2.10
Released October 19, 2016
  • Resolved an issue where the Covenant Eyes service was waking the PC from sleep mode.
  • Improved compatibility with Outlook, Avast, Steam, and Paratext.
