goatak's Issues

EUD disconnect kills server process.

I have an android device running the current playstore version (v4.10.0.39) of ATAK. I am running goatak version server_0.14.6_linux_amd64. I can connect from ATAK to the server using port 8999, however if I disconnect (uncheck the box beside the server profile in ATAK) from the server it crashes.

I also tested this with client_0.14.6_linux_amd64 running on the same machine by stopping the client (ctrl+d in the window running the client process) and produced the same result.

DataPackages visibility got overwritten when a public data package is re-send to other contact privatelly

Steps to reproduce:

• Send a package to the server.
• Receive it on other device and download it.
• Sent the same package downloaded to the second device privatelly to other device.

Tool: "public" got overwritted with private.

basic Missions/DataSync support

(Question) Lines on map

Is it possible goatak client could display lines on the map if sent CoT message in such a way that would generate a line originating from gps location of the client?

There is a problem when accessing the embedFS on Windows build.

The console will show something like "open templetes/head.html file not exist" and which leads to the web ui failure.
I have solved the problem by adding

fname = strings.ReplaceAll(fname, "\\", "/")

which means change the Windows like separator into Unix like separator, before the filename sends to fs.Readfile()

However, maybe my solution is not so perfect and may cause other problems, could you please check if my solution always work nice or fix it with another way?

iTAK Compatibility

We can't connect using iTAK, using TCP nor TCP SSL.

Is iTAK supported?

Duplicated message to Freetakserver

22.04 with GoAtak client connected to the free Freetakserver online.

When sending a message it appears duplicated in list of messages. For example, when connecting to the Freetakserver you get the first intro message. Sending a message such as “test” and going to view messages shows it twice and message found goes from one (initial welcome message) to account of three. In the console where goatak client is running it also appears there’s an issue getting a list of clients, but I will double check again.

Is this a known incompatibility with Freetakserver?

Broadcasting COTs are seen from all Scopes

Steps to reproduce:

1. Login using WinTAK using an account with scope: scopeA
2. Login with other device using an account with scope: scopeB
3. Create a COT with Account A and press Broadcast.
4. Scope B can see the broadcasted COT

A quick question...

Im attempting to install this on a raspberry pi. The docker command gives me this:

"WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
exec ./goatak_server: exec format error"

Is there no docker for Arm64?
