Linux Testing

[Moon Wizard]

Technically, we only support Ubuntu Linux, based on the Unity engine.

Given that, it looks like maybe there are multiple network interfaces on the machine, but some are not connected; or that the network interface is not stable (i.e. losting/regaining connection). Maybe try disabling wireless, and connecting via wired connection?

Hi All,

I recently switched back to linux after being on windows for a few years. I am running Linux Mint v22.
I have installed FGU and copied over my campaigns from the windows drive.
When I fire my main one up I am seeing the following:


In the chat it says:


Any idea what is going on or how I should resolve this?

Thanks,
Craigbert

I don't know if this will be the same issue, but another Mint user had networking issues recently: https://www.fantasygrounds.com/forum...l=1#post724900

OK, I understand that you guys have to pick and choose distos to support ~ I am fine with that. There are too many variations and very few, if indeed any, companies have the resources to support multiple.
Linux Mint is Ubuntu based and I know that doesn't mean you guys have to support it, but at least it is in the same family ~ maybe that is worth something or maybe it is worth nothing, but that aside for the moment.

OK. I have three network interfaces on my machine and they are the same basic three that most laptops / desktops have:
loopback
eth01 ~ physical media cable
wlo1 ~ wireless.
My wireless one is the only one in use and configured. Are you suggesting that my OS is trying to use one of the others at random times? That does not make much sense to me, but you have been doing this a while and I trust you guys. So what have you guys seen that would suggest this is the case? And how does switching to a physical cable resolve this? All three interfaces would still be there.

Thanks,

Craigbert

@Trenloe ~ thanks for pointing this out.

I have two separate computers: 1 Linux, 1 Windows.
Windows Client connecting to the Linux server via the cloud is when I get the disconnect/reconnect issue.
Linux client connecting to the Windows server via the cloud I have no issues.

Based on that I *believe* there is an issue on the Linux side and not on the Windows side nor do I believe that it is a network issue.

I am have not logged into my ATT router yet to see if they are blocking IP6 addresses, but I will do that in a wee bit.

Any other thoughts on what I should check or try?

THANK YOU!!!

Hi All,

I don't want to jinx this, but I may have found a solution.
In /etc/sysctl.conf
Add the following:

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_window_scaling = 1

You will need to reboot.

I got those settings from this forum post:

Hi All,

I am still getting the initial error reported. When I look into the network log I see the following:

I only have the two network interfaces active: loopback (which is required) and wlo1 (wifi)).
Any idea on the cause or resolution?

Thanks.

As mentioned, we only support Ubuntu, because that's the OS that the Unity game engine which we use supports. We're not hearing any reports like this on any other platforms, nor do we have a Linux client specialist to troubleshoot items for users on unsupported platforms.

You might have better luck asking in a Linux-specific forum that supports Mint and specifically gaming within the Mint environment.

That is completely fair.
I am in the midst of doing some major file cleanup and backup then I am going to wipe out my current Linux install and install Ubuntu.
Everything I am posting here I am doing in hopes that it triggers something in someone's brain that keeps me from going down this full-reinstall road at the last minute.
I am absolutely not angry, upset, etc. about the current situation or with any one here, on Discord or that works for Smiteworks.
I am frustrated, but that is mostly directed at myself for not being more mindful of the OS requirements of FGU.
I have posted over on the Mint forum, but my question has not had a single response since I posted it almost a week ago.

Thanks,

Craigbert

I have been using Manjaro (which is an Arch based distro) since FGU launched with no problems.

But.. stick with Ubuntu if you are comfortable.
