[Solved] The Port 7590 problems

sarahuang 2017-02-22 04:16:11 UTC #1

Hi,Vincrossers
Where can download the whole SDK not only MIND CLI ?
When I build the examples, have some error,like this
cannot find package “mind/core/framework/skill” in any of:
/usr/local/go/src/mind/core/framework/skill (from $GOROOT)
/Users/user/go/src/mind/core/framework/skill (from $GOPATH)

I think it is less the mind source file not MIND CLI. Can u open source the Mind SDK?

Hi Sarah.
The reason that is happening is because currently the MIND SDK exist only on the robot.
Current version of mindcli compiles the source code on the HEXA for the ARM processor architecture and since your PC probably is running x86, you can not compile the examples locally.
mind run will pack your Skill and upload it to the HEXA for compilation.

However,
We are currently working hard on a cross compiling toolchain that will make it possible to compile locally on PC but in the meanwhile please refer to the guide at: https://www.vincross.com/developer/introduction/getting-started

Best regards / Ted

Can u open the schematic?

Kaiqiang 2017-03-02 02:54:17 UTC #4

Would you mind elaborating what kind of schematic you are looking for?

I have a similar issue "mind run" gives this:

exit status 1: var/local/mind/skills/helloworld/src/helloworld/cmd/main.go:11:2: no buildable Go source files in /usr/local/src/mindskills/skill-helloworld

I am trying to use the hexa in direct link mode because I cannot change the access point that the hexa connects to.

Could you tell me the version of your MIND Command-line Interface?

I think you can try to follow introduction on https://developer.vincross.com/developer/introduction/getting-started/macos-&-linux to try again.

It works fine on my computer.

Then the run command gets stuck.

Does it matter that I am in direct link mode?
I have permission from the owner on my account. And the MIND CLI is v0.5.1.

Thanks for your help

It seems because of MIND system on your HEXA is an really old version. I think you should try to upgrade it first.

bb2515 2017-07-07 02:16:47 UTC #9

I'm also having issues connecting the HEXA to wifi APs and now can no longer connect via a direct link to the HEXA. I am unsure how to update the HEXA as a result of this.

Is it possible to reset the HEXA? or connect via a hardware interface to update the MIND system?

mirco.becker 2017-07-19 09:47:06 UTC #10

I have issues when scanning for HEXA from Mac.
Port seems to be blocked:
Port 7590 already in use

Mingzhao.Xu 2017-07-19 10:07:46 UTC #11

@mirco.becker

I think it might because port 7590 already used by another process, I would suggest you to find and stop that process.

lsof -iudp -sTCP:LISTEN -n -P | grep 7590
lsof -itcp -sTCP:LISTEN -n -P | grep 7590

These two commands work on my MAC.

mirco.becker 2017-07-21 04:05:26 UTC #12

thx, but the strange thing is that all test show that port 7590 is free. i pinged it directly form a different computer in the network - works fine, have nothing show up on Wireshark and also the terminal commands you suggested gives no indication of the port being used. Anything else that mind might not happy about and throws a port exception?

mirco.becker 2017-07-21 04:05:31 UTC #13

I see that the $ mind scan command runs as loopback so that might cause the used port exception. It does not seem right to me, why would it run as a loopback when it is looking for a device on the same network.

Mingzhao.Xu 2017-07-21 05:47:19 UTC #14

@mirco.becker Thanks a lot for your feedback.

From your description, I think it might be a bug of mind in your network config.

mindsdk project is open sourced, and from the code on github.com we actually loop all your network interfaces and filter loopback interfaces out with golang's standard libraries. I am not sure why it's not working correctly in your environment.

github.com

vincross/mindsdk/blob/master/cli/mindcli/getip.go#L36


}


func GetLocalIPs() ([]net.IP, error) {
	ips := []net.IP{}
	addrs, err := net.InterfaceAddrs()
	if err != nil {
		return nil, err
	}
	for _, addr := range addrs {
		if ip, ok := addr.(*net.IPNet); ok &&
			!ip.IP.IsLoopback() &&
			ip.IP.To4() != nil {
			ips = append(ips, ip.IP)
		}
	}
	return ips, nil
}

I think you can try these things for next:

Try to modify the project by yourself if you like.
As a workaround you can modify ~/.mind.json directly to setup ip address and name to skip mind scan, the format is:

{
  "DefaultRobotName": "HEXA",
  "Robots": [
    {
      "Name": "HEXA",
      "IP": "192.168.1.148"
    },
    {
      "Name": "Jackie",
      "IP": "192.168.1.124"
    }
  ],
  "DockerImage": ""
}

We will also keep trying to figure out where's the problem between our program and your network config. Thanks!

Tianqi 2017-07-21 10:28:40 UTC #15

Hi @mirco.becker , we'll look into this asap and make sure it works for you. Will let you know.

Mingzhao.Xu 2017-07-21 11:14:05 UTC #16

@mirco.becker, would you mind run commands to help us find the detail reason of why the port is already in use?

$ wget https://gist.githubusercontent.com/kilnyy/27998cf472339c9fb0a47ead417e9728/raw/7d21afd5242d26e00d3f609b4e0ddeec1c81fa6e/test-port.go
$ go run test-port.go 7590

It would be good if you can also test some other random ports and tell us the results to see if it a problem for only 7590 or also for others. Thanks!

mirco.becker 2017-07-22 01:11:27 UTC #17

sorry for super basic questions here but how do I run test-port.go on MacOS Terminal without GO install on the machine. Shall I install GO or can I point it to the mind Docker?
We got a solution and a clean VM with ubuntu but I guess that is exactly the point for using Docker, not having the handle chunky VMs.

Mingzhao.Xu 2017-07-22 04:03:33 UTC #18

mind scan is running outside Docker to find robots in your network, so it is better to run this test on your MacOS.
You need to install GO to go run test-port.go. you can also choose to download this pre-compiled test-go and run with following commands.

Thanks for helping us detecting the problem!

$ wget -O test-port https://cdn-file.vincross.com/5972c938733a660009000010
$ chmod +x test-port
$ ./test-port 7590

mirco.becker 2017-07-26 06:24:41 UTC #19

Thanks, that script somehow cleared port 7590 and everything is now running. Still a bit of a mystery to me why that happens but hey. Hope to have some new development soon to pay back for your help.

Mingzhao.Xu 2017-07-26 06:58:33 UTC #20

Good news! I still think it’s because of some other process are using port 7590, if this problem happens next time, please kindly let us know. Thanks!
